How Do Hackers Hack Phones and How Can I Prevent It?

How do hackers hack phones? In several ways. But also, there are several ways you can prevent it from happening to you. The thing is that our phones are like little treasure chests. They’re loaded with plenty of personal data, and we use them to shop, bank, and take care of other personal and financial matters—all of which are of high value to identity thieves. However, you can protect yourself and your phone by knowing what to look out for and by taking a few simple steps. Let’s break it down by first understanding what phone hacking is, taking a look at some common attacks, and learning how you can prevent it.

What is phone hacking?

Phone hacking refers to any method where an unauthorized third party gains access to your smartphone and its data. This isn’t just one single technique; it covers a wide range of cybercrimes. A phone hack can happen through software vulnerabilities, like the spyware campaigns throughout the years that could monitor calls and messages. It can also occur over unsecured networks, such as a hacker intercepting your data on public Wi-Fi. Sometimes, it’s as simple as physical access, where someone installs tracking software on an unattended device. 

Types of smartphone hacks and attacks

Hackers have multiple avenues of attacking your phone. Among these common methods are using malicious apps disguised as legitimate software, exploiting the vulnerabilities of unsecure public Wi-Fi networks, or deploying sophisticated zero-click exploits that require no interaction from you at all. The most common method, however, remains social engineering, where they trick you into giving them access. Let’s further explore these common hacking techniques below.

Hacking software

Whether hackers sneak it onto your phone by physically accessing your phone or by tricking you into installing it via a phony app, a sketchy website, or a phishing attack, hacking software can create problems for you in a couple of ways:

  • Keylogging: In the hands of a hacker, keylogging works like a stalker by snooping information as you type, tap, and even talk on your phone.
  • Trojans: Trojans are malware disguised in your phone to extract important data, such as credit card account details or personal information.

Some possible signs of hacking software on your phone include:

  • A battery that drains way too quickly.
  • Your phone runs a little sluggish or gets hot.
  • Apps quit suddenly or your phone shuts off and turns back on.
  • You see unrecognized data, text, or other charges on your bill.

In all, hacking software can eat up system resources, create conflicts with other apps, and use your data or internet connection to pass your personal information into the hands of hackers.

Phishing attacks

This classic form of attack has been leveled at our computers for years. Phishing is where hackers impersonate a company or trusted individual to get access to your accounts or personal info or both. These attacks take many forms such as emails, texts, instant messages, and so forth, some of which can look really legitimate. Common to them are links to bogus sites that attempt to trick you into handing over personal info or that install malware to wreak havoc on your device or likewise steal information. Learning to spot a phishing attack is one way to keep yourself from falling victim to one.

Bluetooth hacking

Professional hackers can use dedicated technologies that search for vulnerable mobile devices with an open Bluetooth connection. Hackers can pull off these attacks when they are within range of your phone, up to 30 feet away, usually in a populated area. When hackers make a Bluetooth connection to your phone, they might access your data and info, yet that data and info must be downloaded while the phone is within range. This is a more sophisticated attack given the effort and technology involved.

SIM card swapping

In August of 2019, then CEO of Twitter had his phone hacked by SIM card swapping scam. In this type of scam, a hacker contacts your phone provider, pretends to be you, then asks for a replacement SIM card. Once the provider sends the new SIM to the hacker, the old SIM card is deactivated, and your phone number will be effectively stolen. This enables the hacker to take control of your phone calls, messages, among others. The task of impersonating someone else seems difficult, yet it happened to the CEO of a major tech company, underscoring the importance of protecting your personal info and identity online to prevent hackers from pulling off this and other crimes.

Vishing or voice phishing

While a phone call itself cannot typically install malware on your device, it is a primary tool for social engineering, known as vishing or voice phishing. A hacker might call, impersonating your bank or tech support company, and trick you into revealing sensitive information like passwords or financial details. They might also try to convince you to install a malicious app. Another common tactic is the “one-ring” scam, where they hang up hoping you’ll call back a premium-rate number. To stay safe, be wary of unsolicited calls, never provide personal data, block suspicious numbers, and check that your call forwarding isn’t enabled.

Low-power mode hacks

Generally, a phone that is powered off is a difficult target for remote hackers. However, modern smartphones aren’t always truly off. Features like Apple’s Find My network can operate in a low-power mode, keeping certain radios active. Furthermore, if a device has been previously compromised with sophisticated firmware-level malware, it could activate upon startup. The more common risk involves data that was already stolen before the phone was turned off or if the device is physically stolen. While it’s an uncommon scenario, the only sure way to take a device offline and completely sever all power is by removing the battery, where possible.

Camera hacks

Hacking a phone’s camera is referred to as camfecting, usually done through malware or spyware hidden within a rogue application. Once installed, these apps can gain unauthorized permission to access your camera and record video or capture images without your knowledge. Occasionally, vulnerabilities in a phone’s operating system (OS) have been discovered that could allow for this, though these are rare and usually patched quickly. Protect yourself by regularly reviewing app permissions in your phone’s settings—for both iOS and Android—and revoking camera access for any app that doesn’t absolutely need it. Always keep your OS and apps updated to the latest versions.

Android vs. iPhone: Which is harder to hack?

This is a long-standing debate with no simple answer. iPhones are generally considered more secure due to Apple’s walled garden approach: a closed ecosystem, a strict vetting process for the App Store, and timely security updates for all supported devices. Android’s open-source nature offers more flexibility but also creates a more fragmented ecosystem, where security updates can be delayed depending on the device manufacturer. However, both platforms use powerful security features like application sandboxing. 

The most important factor is not the brand but your behavior. A user who practices good digital hygiene—using strong passwords, avoiding suspicious links, and vetting apps—is well-protected on any platform.

Signs your phone has been hacked

Detecting a phone hack early can save you from significant trouble. Watch for key red flags: your battery draining much faster than usual, unexpected spikes in your mobile data usage, a persistently hot device even when idle, or a sudden barrage of pop-up ads. You might also notice apps you don’t remember installing or find that your phone is running unusually slow. To check, go into your settings to review your battery and data usage reports for any strange activity. The most effective step you can take is to install a comprehensive security app, like McAfee® Mobile Security, to run an immediate scan and detect any threats.

How to remove a hacker from your phone

Discovering that your phone has been hacked can be alarming, but acting quickly can help you regain control and protect your personal information. Here are the urgent steps to take so you can remove the hacker, secure your accounts, and prevent future intrusions.

  1. Disconnect immediately: Turn on Airplane Mode to cut off the hacker’s connection to your device via Wi-Fi and cellular data.
  2. Run an antivirus scan: Use a reputable mobile security app to scan your phone, and identify and remove malicious software.
  3. Review and remove apps: Manually check your installed applications. Delete any you don’t recognize or that look suspicious. While you’re there, review app permissions and revoke access for any apps that seem overly intrusive.
  4. Change your passwords: Using a separate, secure device, change the passwords for your critical accounts immediately—especially for your email, banking, and social media.
  5. Perform a factory reset: For persistent infections, a factory reset is the most effective solution. This will wipe all data from your phone, so ensure you have a clean backup—the time before you suspected a hack—to restore from.
  6. Monitor your accounts: After securing your device, keep a close eye on your financial and online accounts for any unauthorized activity.

10 tips to prevent your phone from being hacked

While there are several ways a hacker can get into your phone and steal personal and critical information, here are a few tips to keep that from happening:

  1. Use comprehensive security software. We’ve gotten into the good habit of using this on our desktop and laptop computers. Our phones? Not so much. Installing security software on your smartphone gives you a first line of defense against attacks, plus additional security features.
  2. Update your phone OS and its apps. Keeping your operating system current is the primary way to protect your phone. Updates fix vulnerabilities that cybercriminals rely on to pull off their malware-based attacks. Additionally, those updates can help keep your phone and apps running smoothly while introducing new, helpful features.
  3. Stay safe on the go with a VPN. One way that crooks hack their way into your phone is via public Wi-Fi at airports, hotels, and even libraries. This means your activities are exposed to others on the network—your bank details, password, all of it. To make a public network private and protect your data, use a virtual private network.
  4. Use a password manager. Strong, unique passwords offer another primary line of defense, but juggling dozens of passwords can be a task, thus the temptation to use and reuse simpler passwords. Hackers love this because one password can be the key to several accounts. Instead, try a password manager that can create those passwords for you and safely store them as well. Comprehensive security software will include one.
  5. Avoid public charging stations. Charging your device at a public station seems so convenient. However, some hackers have been known to juice jack by installing malware into the charging station, while stealing your passwords and personal info. Instead, bring a portable power pack that you can charge ahead of time. They’re pretty inexpensive and easy to find.
  6. Keep your eyes on your phone. Many hacks happen simply because a phone falls into the wrong hands. This is a good case for password or PIN protecting your phone, as well as turning on device tracking to locate your phone or wipe it clean remotely if you need to. Apple and Google provide their users with a step-by-step guide for remotely wiping devices.
  7. Encrypt your phone. Encrypting your cell phone can save you from being hacked and can protect your calls, messages, and critical information. To check if your iPhone is encrypted, go into Touch ID & Passcode, scroll to the bottom, and see if data protection is enabled. Typically, this is automatic if you have a passcode enabled. Android users have automatic encryption depending on the type of phone.
  8. Lock your SIM card. Just as you can lock your phone, you can also lock the SIM card that is used to identify you, the owner, and to connect you to your cellular network. Locking it keeps your phone from being used on any other network than yours. If you own an iPhone, you can lock it by following these simple directions. For other platforms, check out the manufacturer’s website.
  9. Turn off your Wi-Fi and Bluetooth when not in use. Think of it as closing an open door. As many hacks rely on both Wi-Fi and Bluetooth to be performed, switching off both can protect your privacy in many situations. You can easily turn off both from your settings by simply pulling down the menu on your home screen.
  10. Steer clear of unvetted third-party app stores. Google Play and Apple’s App Store have measures in place to review and vet apps, and ensure that they are safe and secure. Third-party sites may not have that process and might intentionally host malicious apps. While some cybercriminals have found ways to circumvent Google and Apple’s review process, downloading a safe app from them is far greater than anywhere else.

Final thoughts

Your smartphone is central to your life, so protecting it is essential. Ultimately, your proactive security habits are your strongest defense against mobile hacking. Make a habit of keeping your operating system and apps updated, be cautious about the links you click and the networks you join, and use a comprehensive security solution like McAfee® Mobile Security.

By staying vigilant and informed, you can enjoy all the benefits of your mobile device with confidence and peace of mind. Stay tuned to McAfee for the latest on how to protect your digital world from emerging threats.

How To Tell If Your Smartphone Has Been Hacked

Smartphone hacking is the unauthorized access to and control over a mobile device or its communications. This goes beyond a simple malware infection; it’s a targeted breach aimed at stealing your personal data, spying on your activities, or using your device for malicious purposes. Unlike general viruses that may just slow down your device, a hack can lead to severe real-world consequences. This article aims to increase your awareness about hacking methods, how to prevent it or determine if your phone has been infiltrated, and how to protect your phone moving forward.

Why cybercriminals target smartphones

Your smartphone is a goldmine of personal information, making it a high-value target for cybercriminals whose motivations are typically centered on financial gain and identity theft. Hackers seek banking credentials, credit card numbers, and access to payment apps for direct financial theft. Meanwhile, stealing your personal information—like emails, contacts, and passwords—allows them to commit identity fraud or sell on dark-web markets.

Beyond money, attackers may use your phone for surveillance, secretly activating your camera or microphone to spy on you. In other cases, they may hijack your device’s resources to include it in a botnet for larger attacks or hold your files hostage with ransomware. Understanding these threats is the first step in knowing how to protect yourself from them, so it’s vital to learn the methods hackers use to get into your phone.

Hackers exploit iOS and Android differently

While both iOS and Android are secure, their core philosophies create different opportunities for hackers. Android’s open-source nature allows for greater customization, including the ability to “sideload” third-party apps from outside the official Google Play Store. Unvetted apps with malicious code are a primary vector for malware.

In contrast, Apple’s iOS’s closed ecosystem makes it much harder to install unauthorized software. For this reason, many attacks targeting iPhones rely on social engineering, sophisticated zero-day exploits that target unknown vulnerabilities, or jailbroken devices, which strips away Apple’s built-in protections.

To protect your device, tailor your defense to its ecosystem. The best practice for Android users is to stick to the Google Play Store and ensure Google Play Protect is active, as it continuously scans your apps for harmful behavior. iPhone users concerned about targeted attacks should activate Lockdown Mode, an extreme feature that limits functionality to reduce the potential attack surface. Regardless of your platform, keeping your operating system updated is the single most important step you can take to stay secure.

Common attack vectors

Wondering how your phone gets compromised? Hackers use several common pathways.

Jailbreaking or rooting

A hacker might install spyware after you jailbreak or root your smartphone to bypass the security of their respective stores. Jailbreaking or rooting gives smartphone users more control over their devices, such as removing pre-installed apps and installing third-party apps from unvetted sources. However, this action removes barriers that keep viruses and malware from entering the smartphone’s system and spreading to apps, files, devices and other networks. And because Apple and Google don’t review the apps in those sources, this allows the hacker to post a bad app with relative ease.

Sneaking a malicious app update

Apple has a strict review policy before apps are approved for posting in the App Store. Meanwhile, Google started applying AI-powered threat detection, stronger privacy policies, supercharged developer tools, industry-wide alliances, and other methods in its app reviews. Bad actors, however, could still sneak malware into the stores by uploading infected app versions during updates. Other times, they’ll embed malicious code that triggers only in certain countries or encrypt malicious code into the app they submit, making it difficult for reviewers to sniff out.

Remote hacking

Cybercriminals have several sophisticated methods to hack smartphones remotely. One common technique is phishing, where you might receive a text or email with a malicious link that, when clicked, installs spyware on your device. Another remote hacking vector is through unsecured public Wi-Fi networks, where hackers can intercept your data. Spyware can also be delivered via SMS payloads that require no user interaction.

Text messages

Smishing (SMS phishing) is a common and effective way for hackers to attack your phone, where they send an urgent text with a malicious link, like a fake delivery notification or a bank alert, to trick you into clicking without thinking. Once you click, the link can lead to a fake website designed to steal your login credentials or directly download malware onto your device. Attackers also use MMS messages to send malicious files, like images or videos, which in some rare “zero-click” exploits, can infect your phone without you even opening the message.

To protect yourself, treat all unexpected links in text messages with suspicion. Never click on a link from an unknown sender. A key preventive step is to go into your messaging app’s settings and disable the automatic download of MMS files. This prevents malicious media from loading onto your device automatically. Always verify urgent requests by contacting the company or person directly through a trusted channel, not by using the contact information provided in the suspicious text.

Malicious websites

In this method, hackers use techniques like drive-by downloads, which silently installs malware onto your device the moment a page loads—no click required. Malvertising is where malicious code is hidden in online ads that, if served on a site you visit, can trigger a spyware or ransomware download. These attacks are most effective against devices with outdated web browsers, as they target known security holes that have since been patched. Fake “update required” pop-ups are designed to scare you into installing malicious software disguised as a critical browser update. To protect yourself, always keep your mobile browser and operating system fully updated. Use your browser’s built-in safe-browsing features, and be cautious about granting permissions or clicking links on unfamiliar websites.

SIM-swap and phone cloning

These two sophisticated attacks can give a hacker complete control over your phone number. In a SIM-swap attack, a criminal tricks your mobile carrier into transferring your phone number to a SIM card they control. In phone cloning, they copy the identifying information from your phone to another, making a functional duplicate. In either case, the attacker can then intercept your calls, texts, and two-factor authentication codes.

Proactive defense includes setting up a unique PIN or password on your account for an extra layer of security. Switch to an eSIM if possible, as eSIMs are not as easily swapped as physical cards. If you suspect an attack, immediately report the issue to your carrier and check your financial and email accounts for unauthorized activity. You can also use the dial codes, like *#62#, to see if your calls are being forwarded to an unknown number.

Compromised phone camera

Malicious apps and spyware can secretly access your camera and microphone, potentially livestreaming audio and video to an attacker without your knowledge. Key warning signs include the camera indicator light turning on unexpectedly, significant and unexplained battery drain, or finding unfamiliar photos and videos in your gallery. To protect yourself, regularly audit the apps installed on your phone. Go into your device’s settings to review which apps have permission to access your camera and revoke access for any that don’t need it.

Other methods

Network-based attacks occur over unsecured public Wi-Fi where attackers can intercept your data. Finally, unsecure cloud backups can be a weak point, as a compromised password for your Apple or Google account could give a hacker access to all the data you’ve stored. Knowing these attack vectors is the first step toward understanding how to know if your phone is hacked.

Signs your smartphone has been hacked

Because we spend so much time on our phones, it’s fairly easy to tell when something isn’t working right. Sometimes those issues are symptoms of an infection. Possible signs that your device has been hacked include:

  • Performance issues: A slower device, webpages taking way too long to load, or a battery that never keeps a charge can be attributed to your device reaching its retirement. However, these things might also signal that malware has compromised your phone.
  • Your phone feels hot: Malware running in the background of your device might burn extra computing power, causing your phone to feel overheated.
  • Mysterious calls, texts, or apps: If apps you haven’t downloaded suddenly appear on your screen, or if outgoing calls you didn’t make pop up on your phone bill, these are definite red flags that your device has been hacked.
  • Changes or pop-ups crowd your screen: If you are getting an influx of spammy ads or your app organization is suddenly out of order, or your home screen has been reorganized, there is a big possibility that your phone has been hacked.
  • Unexpected battery drain: Your phone’s battery dies much faster than usual because malware is constantly running in the background.
  • Sudden data spikes: You notice a sharp, unexplained increase in your mobile data usage as spyware sends your information to a hacker.
  • Unexplained charges: You find subscriptions or premium service charges on your phone bill or to your account that you never authorized.
  • Background noise on calls: You hear clicks, static, or distant voices during phone conversations, which could indicate a call-monitoring app is active.
  • Sudden loss of mobile service on your phone, notifications of account changes you didn’t make, or being locked out of your online accounts.

Confirm a breach with built-in diagnostics

If these symptoms are present, use the following tools to verify whether your device has been compromised:

  1. For Android, run Google Play Protect: This is your first line of defense on an Android device. Open the Google Play Store app, tap your profile icon in the top right, and select Play Protect. Tap “Scan” to check your installed apps for harmful behavior. Play Protect runs automatically but a manual scan can help confirm if your phone is hacked.
  2. For iOS, use Apple’s Safety Check: To check if your iPhone has been hacked, go to Settings > Privacy & Security > Safety Check. This tool helps you review and revoke the access you’ve granted to people, apps, and devices, which is a common way iPhones are compromised.
  3. Install a reputable antivirus scanner: For a deeper analysis, install a trusted mobile security app like McAfee to detect a wider range of malware, spyware, and risky settings. Run a full system scan.
  4. Interpret the results: If the scan detects a threat, it will typically be labeled with a name and a risk level. The security app will also give you an option to remove or uninstall the malware. If you receive a warning but no option to remove, boot your phone into safe mode and manually uninstall the suspicious app.

Hack attack! Your next steps

The results of the scan are in: your smartphone has clearly been hacked. There is no time to lose. To start the process of blocking the hacker or removing the malware, follow these essential first steps:

  1. Remove apps you didn’t install and restart. Check your apps folder for anything unfamiliar and remove them. From there, disconnect from the Internet and restart your phone to halt any malicious activity.
  2. If issues persist, reset. If you still have issues, restoring your phone to its factory settings is an option, provided you have backed up photos, contacts, and other vital info in the cloud. A quick online search can show how relatively straightforward it is to wipe and restore your model of phone.
  3. Flash the stock firmware. As a last resort for technical users, reinstalling the official operating system will almost certainly remove the hack.
  4. Change critical passwords: Using a different, trusted device, immediately change the passwords for your most important accounts—email, banking, and social media.
  5. Check your accounts and credit. Some online security solutions like McAfee+ are capable of Identity Monitoring, which alerts you if your info winds up on the dark web, while Credit Monitoring alerts you of unauthorized activity in your accounts.
  6. Get expert help. Our Identity Theft Coverage & Restoration service offers $2 million that covers required travel, losses, and legal fees associated with identity theft. It also offers the services of a licensed recovery professional who can repair your credit and your identity after a hack attack.
  7. Notify financial institutions: Contact your bank and credit card companies to alert them to the potential breach. Monitor your statements closely for any fraudulent charges.
  8. Report the incident: Inform your mobile carrier about the breach and consider filing a report with the appropriate authorities, such as local law enforcement and the FBI’s Internet Crime Complaint Center.

Seek professional help

Persistent problems with your smartphone after a factory reset, may indicate a sophisticated, low-level hack. If you are the victim of significant financial fraud or identity theft, or if the hack involves sensitive legal or corporate data, it is crucial to stop using your smartphone and get assistance. In these cases, continued use could tamper with evidence.

After reporting the hacking incident to your mobile carrier, and authorities, you may need a certified digital forensic analyst for deep analysis, especially in corporate or legal cases. Before you call, gather key information: the make and model of your phone, the date you first noticed issues, a list of suspicious apps or messages, and any known fraudulent activity on your accounts.

Dial codes to detect hidden hacks

Certain dial codes, also known as Unstructured Supplementary Service Data (USSD) or Man-Machine Interface (MMI) codes, can help you check for signs of suspicious activity or hidden configurations. These codes can reveal call forwarding, SIM tracking, or conditional redirects that may indicate a compromise:

  • Dial *#21#: This code shows you the status of call forwarding. If calls, messages, or other data are being diverted without your knowledge, this is one of the key signs your phone is hacked. The results should all say “Not Forwarded.”
  • Dial *#62#: Use this code to find out where calls are being forwarded when your phone is unreachable (e.g., turned off or out of service area). It should typically go to your carrier’s voicemail number, so check if the number shown is unfamiliar.
  • Dial ##002#: This universal code disables all call forwarding. If you suspect your calls are being diverted, dialing this code will reset it. Note that availability and functionality of these codes can vary by carrier and country.

Tips to block hackers from your phone

You can take simple, effective steps to protect yourself and your device from hackers. Here are some practical tips, from the basic to the more layered steps, to help you block hackers from accessing your phone.

Basic best practices

To avoid the hassle of having a hacked phone in the first place, here are some fundamental measures you can do as part of your routine:

  • Update your phone and its apps. Promptly updating your phone and apps is a primary way to keep your device safer. Updates often fix bugs and vulnerabilities that hackers rely on to download malware for their attacks.
  • Avoid third-party apps from unvetted stores. Apple’s App Store and Google Play have protections in place, unlike third-party sites which sometimes purposely host malicious apps. Avoiding these sites altogether can block hackers from your device.
  • Don’t use a jailbroken or rooted phone. Jailbreaking or rooting a phone introduces all kinds of security issues. Your best bet as an everyday internet user is to rely on the built-in security features of iOS and Android.

Layered protection beyond the basics

Beyond the foundational advice, fortifying your smartphone requires a layered defense. We suggest the following actions you can apply:

  • Install a reputable mobile security app: A trusted provider like McAfee can scan for malware and alert you to risky websites.
  • Enable two-factor authentication: Use this feature on all critical accounts, such as your email, banking, and social media apps. This adds a crucial second layer of verification that protects you even if your password is stolen.
  • Disable connective services: Minimize your attack surface by disabling wireless radios like Bluetooth, near field communication (NFC), and location tracking when not in use.
  • Leverage hardware security: Rely on built-in hardware features like Apple’s Secure Enclave or Android’s Titan M chip, which protect your biometric data and encryption keys.
  • Review app permissions regularly: Make it a monthly habit to check which apps have access to your camera, microphone, location, and contacts, revoking permissions from any that seem unnecessary.
  • Adopt a zero-trust mindset: Never automatically trust links or attachments in emails and messages, even if they appear to be from someone you know. Use a VPN on public Wi-Fi to encrypt your connection and protect your data from eavesdroppers. In addition, ensure your device’s storage is always encrypted for a strong baseline of protection.
  • Take full advantage of built-in safety features: Apple offers Lockdown Mode for high-risk users, while Google has Play Protect which continuously scans your apps for harmful behavior.
  • Avoid using public USB charging stations: These can be used for juice jacking, where hackers steal data from or install malware on your device. It’s best to bring a portable battery pack, especially during travel or long days out.

One-tap checklist: Security settings you can enable today

Securing your device doesn’t have to be complicated or time-consuming. In fact, many powerful protections are just a tap away. This quick checklist offers quick and simple security settings you can enable with minimal effort.

  1. Turn on automatic updates: Go to Settings > General > Software Update on iOS or Settings > System > System Update on Android to enable automatic updates and ensure you always have the latest security patches.
  2. Enable biometric lock: Set up Face ID or Touch ID (iOS) or Fingerprint Unlock (Android) for a fast, secure way to protect your device from unauthorized physical access.
  3. Activate “Find My” feature: Turn on Apple’s “Find My iPhone” or Android’s “Find My Device” to allow you to locate, lock, or remotely erase your phone if it’s lost or stolen.

FAQs about phone hacking

Does dialing *#21# show if I’m hacked?

This code shows if your calls and messages are being forwarded, which can be a sign of a hack, but it doesn’t detect other types of malware or spyware.

Can iPhones get viruses?

While less common due to Apple’s strong security structure, iPhones can still be compromised, especially through malicious apps from outside the App Store or sophisticated phishing attacks.

Will a factory reset remove spyware?

In most cases, yes. A factory reset erases all data and apps on your device, including most forms of malware and spyware, returning it to its original state.

Can my phone be hacked while powered off?

A phone that is truly powered off cannot be hacked remotely. When the device is off, its wireless radios (cellular, Wi-Fi, Bluetooth) are inactive, and the operating system is not running, cutting off any connection for an attacker to exploit. In Airplane Mode, only the radios are disabled, but leaves the OS running.

The myth of a phone being hacked while off often stems from two things: advanced, targeted attacks that fake a shutdown to compromise firmware, or physical attacks like a “cold boot” where a forensics expert with physical access can extract data from the RAM shortly after shutdown. To mitigate these extremely rare risks, always ensure your phone is fully encrypted, a default setting on modern iPhones and Androids, to make data unreadable even if accessed physically.

For everyday security, shutting off your phone is a good first step to sever any potential malicious connection.

Does my iPhone need antivirus?

If your iPhone is not jailbroken, you don’t need antivirus. But your phone should still get extra protection to deal with other cyberthreats such as scammy text messages, phishing and AI-driven attempts. Comprehensive online protection software like McAfee keeps you and your phone safer. It can:

  • Block sketchy links in texts, emails, messages, as well as suspicious links during searches, while surfing, and on social media.
  • Protect your identity by keeping tabs on your credit and accounts.

Those are only some of the many McAfee capabilities that protect you and your phone.

Final thoughts

Recognizing the signs your phone is hacked is the critical first step, but swift and correct action is what truly protects you.

You can usually determine your smartphone has been hacked by observing any unusual behavior patterns, such as unexplained battery drain, data usage spikes, a blitz of ad pop-ups, unexplained charges on your banking accounts, and even mysterious calls, texts, or apps. Another way to confirm a breach is by running built-in diagnostics such as security scans and security keys. If any of the odd behaviors listed above sound familiar, don’t wait. Take immediate action and implement a layered defense.

In the first place, you can significantly reduce your risk of being hacked through regular software updates, careful app management, and smart browsing habits. Another important component is installing a complete privacy, identity and device solution like McAfee that provides comprehensive protection.

Don’t wait until you suspect a breach; adopt these protective strategies today to keep your digital life private and secure.

How to Know If Your Phone Has Been Hacked

“My phone’s been hacked!” These are words you never want to hear or say. Ever. You are not alone in this sentiment.

Our phones have become the central hub of our lives, storing everything from personal and financial information, access to payment apps, files, photos, and contacts. This has made our phones irresistible, prized targets for cyber criminals. And because these devices are always on and always with us, the opportunity for attack is constant. What are the signs that you have been hacked and how can you reclaim your control? This guide walks you through the common indicators of a hacked phone and what steps you can take to protect your data and privacy.

What is phone hacking and how does it work?

Phone hacking is the unauthorized access and control of your smartphone and its data. It can happen to any person and any device, whether it’s an iPhone or an Android. To achieve this, cybercriminals—also called hackers—use various types of malicious software, sometimes called malware, such as:

  • Spyware, which secretly tracks your every move
  • Adware, which bombards your device with pop-up ads
  • Ransomware, which locks your files until you pay a fee 

These attacks are typically motivated by financial gain, such as stealing banking credentials, or by a desire to monitor someone’s personal life. 

The cost of phone hacking to you

Phone hacking isn’t just a technical or convenience issue. It has real and often costly consequences for your personal life, finances, and privacy. Here, we list the kinds of losses you might face with a hacked phone:

  • Financial loss: Hackers can access banking apps to drain your accounts, steal credit card information for fraudulent purchases, or use your phone to subscribe to premium services without your consent.
  • Identity theft: Cybercriminals can steal personal information from your device, such as your social security number, passwords, and photos—to open new accounts or commit crimes in your name.
  • Severe privacy invasion: Through spyware, an attacker can turn on your phone’s camera and microphone to secretly record you, track your location in real-time, and read all your private messages.
  • Emotional and reputational damage: The stress of being hacked is significant. A criminal could use your accounts to impersonate you, spread misinformation or damage your relationships with family, friends, and colleagues.

The consequences of a hacked phone go far beyond inconvenience. This is why it is so critical to stay alert for the warning signs of a compromise and know exactly what to do if your phone is hacked.

Common ways hackers gain access to your smartphone

The unfortunate reality is that anyone’s phone can be targeted and successfully hacked. Cybercriminals have developed several sophisticated methods that allow them to remotely take over your device. These tactics are done mainly by surreptitiously installing malicious software or malware, monitoring calls and messages, stealing personal information, or even taking over your various accounts. Here are detailed explanations for each hacking method:

  • Malicious apps: Malware can be disguised as legitimate applications, such as games and utility tools, available on unofficial third-party app stores. Once installed, it can steal data, track your location, or install more malware. Always be cautious of apps that ask for permissions that exceed their intended function, such as a calculator app requesting access to your contacts.
  • Visiting malicious websites: Visiting a compromised website on your phone could infect it with malware through a drive-by download which automatically installs malicious software, scripts that exploit your phone’s operating system vulnerabilities, or pop-ups or ads that trick you into authorizing a download, often disguised as a software update or a prize notification. 
  • Phishing or smishing: You might receive a text message (SMS) or email that appears to be from a trusted source, like your bank or a delivery service. These messages contain links that lead to fake websites designed to trick you into entering your passwords or personal information. A common example is a text claiming there’s a problem with a package delivery, urging you to click a link to reschedule.
  • Unsecured public Wi-Fi: When you connect to a free, public Wi-Fi network at a café, airport, or hotel without protection, your data can be vulnerable. Hackers on the same network can intercept the information you send, including passwords and credit card details. Using a virtual private network (VPN) protects you on public networks.
  • SIM swapping: This sophisticated scam involves a hacker impersonating you and convincing your mobile carrier to transfer your phone number to a new SIM card they control. Once they have your number, they can intercept calls and texts, including two-factor authentication codes, allowing them to take over your online accounts.
  • Juice-jacking: Cybercriminals can modify public USB charging stations to install malware onto your phone while it charges. This technique can steal sensitive data from your phone. It’s always safer to use your own AC power adapter and a wall outlet.
  • Outdated operating systems: Hackers actively search for security holes in older versions of iOS and Android. Installing the latest security updates for your phone’s operating system locks the doors to malware as these updates contain critical patches that protect you from newly discovered threats.

12 signs your phone was hacked

To be certain that your phone has been hacked, here are some signs you should consider. Note that these might be signs of a hacked phone, yet not always. 

  1. More popups than usual: Phones hit with adware will be bombarded with pop-up ads. Never tap or click on them, as they might take you to pages designed to steal personal information.
  2. Data spikes or unknown call charges: A hacker is likely using your phone to transfer data, make purchases, send messages, or make calls via your phone. 
  3. Issues with online accounts: Spyware might have stolen your account credentials, then transmitted them to the hacker, leading to credit and debit fraud. In some cases, hackers will change the password and lock out the device owner.
  4. Unexpected battery drain: Your phone’s battery dies much faster than usual because hidden malware is constantly running in the background.
  5. Sluggish performance: Your device freezes, crashes, or lags significantly as malicious software consumes its processing power and memory.
  6. Unfamiliar apps or messages: You discover apps you never installed or see outgoing calls and texts you didn’t make, indicating unauthorized use.
  7. Phone overheats while idle: Your device feels unusually warm even when you’re not using it, a sign of malware overworking the processor.
  8. Random reboots or shutdowns: The phone restarts on its own, which could be caused by conflicting malicious code or a hacker remotely controlling it.
  9. Camera or mic activates unexpectedly: Someone may be spying on you when the camera or microphone indicator light turns on when you aren’t using it.
  10. Websites look different: Pages you visit look unusual or frequently redirect you to spammy sites, indicating your web traffic is being hijacked.
  11. Unauthorized 2FA requests: You receive notifications for two-factor authentication codes you didn’t request, a strong signal that someone has your password and is trying to access your accounts.
  12. Inability to shut down properly: Your phone resists being turned off or fails to shut down completely, as malware may be designed to keep it running. 

If you see several of these signs, it’s crucial to take immediate action to secure your device and data.

Clarifying misconceptions about phone hacking

Ultimately, the biggest factor in security is user behavior. Regardless of whether you use Android or iOS, practising safe habits—like avoiding suspicious links, using strong passwords, and keeping your operating system updated—is the most critical defense against having your phone hacked.

What’s easier to hack: Android or iPhone?

This is a long-standing debate, and the truth is that both platforms can be hacked. Android’s open-source nature and accommodation of third-party sources apps create more potential vulnerabilities. Additionally, security updates can sometimes be delayed depending on the device manufacturer. iPhones, while generally more secure, can be vulnerable if a user jailbreaks the device or falls victim to phishing and other social engineering scams.

Can answering a phone call get you hacked?

Simply answering a phone call cannot install malware on a modern, updated smartphone. The real danger comes from social engineering, where the caller will convince you into taking an action that compromises your security such as giving your personal information or installing something yourself. This is often called vishing or voice phishing.

Can your phone camera be hacked?

Yes, your phone’s camera and microphone can be hacked, a process known as camfecting. This is typically done using spyware hidden in malicious apps disguised as legitimate software that you may have been tricked into installing. Signs of a compromised camera include the indicator light turning on unexpectedly, finding photos or videos in your gallery that you didn’t take, or experiencing unusually high battery drain.

Can a phone be hacked when turned off?

When your phone is completely powered down, its network connections and most of its hardware are inactive, making it impossible to be actively hacked over the internet. However, some modern smartphones have features that remain active even when the device seems off, like the location tracker. Sophisticated, state-level spyware like Pegasus are also theoretically capable of attacking a device’s firmware even while turned off. 

Hacking off a hacker: A step-by-step recovery guide 

Sometimes you are fortunate enough to catch the hacking attempt while it is in progress, such as during a vishing incident. When this happens, you can take these immediate steps to thwart the hacker before, during and after:

  • Use call screening and blocking: Enable your carrier’s spam call filtering services and manually block any suspicious numbers that call you.
  • Never share one-time codes: Legitimate companies will never call you to ask for a password, PIN, or two-factor authentication (2FA) code. Treat any such request as a scam.
  • Hang up and verify independently: If you receive a suspicious call, hang up immediately. Find the official phone number for the company online and call them directly.

Discovering that your phone has been hacked can be alarming, but acting quickly can help minimize the damage and restore your privacy. Here are the actions to take to regain control and protect your personal information:

  1. Back up essential data: Before taking any action, save your irreplaceable data such as photos, contacts, and important documents to a cloud service or computer. Do not back up applications or system data, as these may be infected.
  2. Disconnect immediately: The first step is to restart your phone in Safe Mode (for Android) or Recovery Mode (for iPhone). This cuts off its connection to Wi-Fi and cellular networks, preventing the hacker from sending or receiving more data.
  3. Run a security scan: Use a trusted mobile security app, like McAfee Mobile Security to scan your device. It’s designed to find and remove malware that may be hiding on your phone.
  4. Delete suspicious apps and files: Manually go through your applications and delete anything you don’t remember installing or that looks unfamiliar. Check your downloads folder for suspicious files and delete those as well.
  5. Clear browser cache and data: Malicious code could be stored in your browser’s cache. Go into your browser settings and clear all history, cookies, and cached data to remove lingering threats.
  6. Change your passwords: From a separate, uninfected device, change the passwords for your critical accounts, including email, banking, and social media. Use a password manager to create and store strong, unique passwords for each account. Enable 2FA where possible for added security. 
  7. Secure your accounts: Review recent activity on your online accounts for any unauthorized transactions or messages. Have your bank accounts frozen and request new cards and credentials.
  8. Update your operating system: Check for and install the latest OS update for your device. These updates often contain critical security patches that can fix the vulnerability the hacker exploited in the first place.
  9. Perform a full shutdown when needed, disable always-on location features if you’re concerned.
  10. Perform a factory reset: If the issues persist, a factory reset is your most effective —and last—option. Once you have backed up files, resetting is a straightforward process and will completely remove any lingering malware.
  11. Verify backups before restoring: After cleaning your device or a factory reset, be cautious when restoring data. Ensure your backup is from a date before the hacking occurred to avoid reinfecting your phone. Restore only essential data and manually reinstall apps only from official app stores.
  12. Notify your contacts and authorities: Let your contacts know your phone was hacked so they can be wary of strange messages from your number. If you suspect identity theft or financial fraud, report it to the relevant authorities and your financial institutions immediately.

Future-proof your phone from hacks

  • Set a SIM PIN: Add a personal identification number to your SIM card through your phone’s settings. This prevents a fraudster from using your SIM in another device to execute a SIM swap attack.
  • Enable automatic security updates: Ensure your phone is set to automatically download and install OS updates. These patches often fix critical security vulnerabilities that hackers actively exploit.
  • Use encrypted DNS: Enable the Private DNS feature on Android or an equivalent app on iOS to encrypt your web traffic lookups. This prevents eavesdroppers on public Wi-Fi from seeing which websites you visit.
  • Disable developer options and USB debugging: These settings are for app developers and can create security backdoors if left on. Turn them off in your phone’s settings unless you have a specific need for them.

Protective measures to take in the first place

Applying security measures the moment you bring home your brand new phone helps to keep your phone from getting hacked in the first place. It only takes a few minutes. Follow these tips to find yourself much safer from the start:  

  1. Install trusted security software immediately. You’ve adopted this good habit on your desktops and laptops. Your phones? Not so much. Online protection software gives you the first line of defense against attacks, and more.
  2. Go with a VPN. Make a public network safe by deploying a virtual private network, which serves as your Wi-Fi hotspot.  It will encrypt your data to keep you safe from advertisers and prying eyes.
  3. Use a password manager. Strong, unique passwords offer another primary line of defense. Try a password manager that can create and safely store them. 
  4. Avoid public charging stations. Look into a portable power pack that you can charge up ahead of time or run on AA batteries. They’re pretty inexpensive and are a safer alternative to public charging stations.  
  5. Keep your eyes on your phone. Preventing the actual theft of your phone is important. This is a good case for password or PIN protecting your phone, and turning on device tracking. In case it is stolen, Apple and Google provide a step-by-step guide for remotely wiping devices.  
  6. Stick with trusted app stores. Stick with legitimate app stores like Google Play and Apple’s App Store, which vet apps to ensure they are safe.
  7. Keep an eye on app permissions. Check what permissions your apps are asking for. Both iPhone and Android users can allow or revoke app permission.
  8. Update your phone’s operating system. Keeping your phone’s operating system up to date can fix vulnerabilities that hackers rely on to pull off attacks—it’s another tried and true method to keep your phone safe and performing well.

Advanced ways to block hackers from your phone

  • Enable a SIM Card PIN: Set up a PIN for your SIM card to prevent hackers from using it in another phone for a SIM swap attack, which requires the PIN upon restart.
  • Use an eSIM if possible: An embedded SIM (eSIM) cannot be physically removed from your phone, making it difficult for criminals to execute a fraudulent SIM swap.
  • Enforce encrypted DNS: Configure your phone to use DNS-over-HTTPS (DoH), which encrypts your DNS queries, preventing eavesdroppers on public Wi-Fi from seeing which websites you visit.
  • Deploy a hardware security key: For the ultimate 2FA protection, a physical key (like a YubiKey) for sensitive accounts makes it nearly impossible for hackers to log in without it.
  • Disable USB debugging and developer mode: Unless you are an app developer, keep these advanced Android features off to close potential backdoors that malware could exploit.
  • Turn off unused wireless radios: Manually disable Wi-Fi, Bluetooth, and NFC when you aren’t using them to reduce your phone’s attack surface and prevent unauthorized connections.

Stay proactive with mobile security

Protecting your phone from hackers doesn’t have to be overwhelming. By remaining vigilant for the warning signs, keeping your software updated, and using trusted security tools, you can significantly reduce your risk of getting your phone infiltrated. Think of your digital security as an ongoing practice, not a one-time fix. 

Mobile security solutions like McAfee Mobile Security are specifically designed to scan your device for malware, spyware, and other malicious code. Key features to look for in a quality security app include real-time antivirus protection, web protection to block dangerous websites, and privacy monitoring to check which apps have access to your personal data.
