This Week in Scams: Why That “Booking Confirmation” Message Might Be Fake

20 March 2026 at 16:46

Today marks the start of Spring in the Northern Hemisphere, and with warmer weather setting in summer trips are vacation planning are starting to take shape.   

But before you respond to that message about your hotel booking or payment confirmation, it’s worth asking: is it actually legit? 

This week in scams, we’re breaking down a travel phishing scheme making the rounds through realistic booking messages, as well as new McAfee research on betting scams and AI-driven malware. 

We’ll walk through what happened, what to watch for, and how McAfee’s tools can help you stay safe. 

Scammers Who Know Your Exact Travel Reservation Details 

A new phishing campaign targeting travelers is exploiting hotel booking platforms like Booking.com, and it’s convincing enough to fool even cautious users. 

According to reporting from ITBrew and Cybernews, attackers are running a multi-stage scam: 

How The Booking Scam Works 

Scam Stage  How It Works  What You’ll Notice  How to Protect Yourself  Where McAfee Helps 
Stage 1: Hotel account gets compromised  Attackers phish or hack hotel staff to access booking platforms and guest reservation data.  You won’t see this part — it happens behind the scenes.  Use strong, unique passwords and enable multi-factor authentication on your own accounts to reduce risk of similar breaches.  Identity Monitoring can alert you if your personal information appears in suspicious places or data leaks. 
Stage 2: You receive a realistic message  Scammers use stolen booking data to send messages via WhatsApp, email, or even booking platforms.  The message includes your real name, hotel, and travel dates, making it feel legitimate.  Be cautious of unexpected outreach, even if the details are correct. Don’t assume accuracy means authenticity.  Scam detection tools can help flag suspicious messages and identify potential phishing attempts. 
Stage 3: Urgency is introduced  The message claims there’s an issue with your reservation and pushes you to act quickly.  Phrases like “confirm within 12 hours” or “risk cancellation” create pressure.  Pause before acting. Legitimate companies rarely require urgent payment changes without prior notice.  Scam detection can help identify high-risk messages designed to pressure you into quick decisions. 
Stage 4: You’re sent to a fake payment page  A link leads to a convincing lookalike site designed to steal your payment details.  The page looks real but may have subtle URL differences or unusual formatting.  Always navigate directly to the official website or app instead of clicking links in messages.  Safe Browsing tools can help block risky or known malicious websites before you enter sensitive information. 

March Madness Brackets, Bets, and Bad Actors 

March Madness brings brackets, bets, and a flood of bad actors. 

New McAfee research found that 1 in 3 Americans (32%) say they’ve experienced a betting or gambling scam, and nearly a quarter (24%) say they’ve lost money to one. On average, victims reported losing $547. 

That’s not surprising when you look at the environment around the tournament. More than half of Americans are watching, more than half are participating in some form of betting, and 82% say they’ve seen betting promotions in the past year. 

Some of the most common setups this season include: 

  • “Guaranteed win” or “can’t lose” betting tips that require payment upfront 
  • Fake sportsbook promotions offering bonus bets or free credits 
  • Messages claiming you have winnings, but need to pay a fee to unlock them 
  • Impersonation scams posing as sportsbook support or betting platforms 
  • Invitations to private “VIP betting groups” on WhatsApp or Telegram 

The takeaway:
If a betting offer promises guaranteed results, demands the use of bizarre apps and sites, asks for money upfront, or pushes you to act quickly, it’s not an edge. It’s a scam. 

“AI-Written” Malware Is Hiding in Everyday Downloads 

Not all scams start with a message. Some start with a search. 

McAfee Labs uncovered a large-scale malware campaign hiding inside hundreds of fake downloads, including game mods, AI tools, drivers, and trading utilities. 

In January alone, researchers identified: 

  • 443 malicious ZIP files disguised as legitimate software 
  • 1,700+ file names used to make those downloads look credible 
  • 48 variants of a malicious DLL file used to infect devices 

These weren’t hosted on obscure corners of the internet either. The files were distributed through platforms people recognize, including Discord, SourceForge, and file-sharing sites. 

Here’s how the attack typically works: 

  • You search for a tool. 
  • You download what looks like the right file. 
  • It opens normally at first. 

Then, behind the scenes, malware loads quietly and begins pulling in additional code. In some cases, victims are shown fake error messages while the real infection happens in the background. 

From there, attackers can: 

  • Turn your device into a cryptocurrency mining machine 
  • Install additional malware like infostealers or remote access tools 
  • Slow down your system while running hidden processes 

What makes this campaign stand out is that some of the code appears to have been generated with help from AI tools. 

That doesn’t mean AI is running the attack on its own. But it does suggest attackers are using AI to: 

  • Generate code faster 
  • Create more variations of malware 
  • Scale campaigns more efficiently 

In other words, the barrier to building malware is getting lower. 

The takeaway:
If a download is unofficial, hard to find, or feels like a shortcut, it’s worth slowing down. The file may look right, but that doesn’t mean it’s safe. 

How McAfee+ Advanced Works in These Scam Moments 

Whether it’s a message about your booking, a betting offer that looks legitimate, or a download that appears to be exactly what you were searching for, these scams all rely on the same thing: they blend into everyday moments. 

That’s where having backup like McAfee+ Advanced comes in. It includes: 

  • McAfee’s Scam Detector, which helps flag suspicious links in texts and messages like the ones used in these booking and betting scams, so you can spot something risky before you engage
  • Web protection and real-time device security, helping protect against risky links, malicious sites, and evolving threats if you do click, including fake betting platforms or malware hidden in downloads
  • Personal Data Cleanup, which helps remove your information from sites that sell it, making it harder for scammers to access the personal details that make messages and scams feel legitimate
  • Secure VPN, which helps keep your personal info safe and private anywhere you use public Wi-Fi, like hotels, airports, and cafés while traveling
  • Identity Monitoring and alerts, with 24/7 scans of the dark web to help ensure your personal and financial information isn’t being exposed or reused
  • Credit and transaction monitoring, so you can get alerts about suspicious financial activity if your information is ever compromised 
  • Identity restoration support and up to $2 million in identity theft coverage, giving you access to US-based experts and added peace of mind if something does go wrong 

Stay skeptical, verify before you click, and we’ll see you next week with more.

How to Secure Tax Documents Before Sending to Your Accountant

19 March 2026 at 13:15

Filing your taxes may not feel risky. You download a W-2. Upload a PDF. Email a document. Move on. 

But tax season is one of the most active times of year for scammers, and the moment you start collecting and sharing tax documents is often when people are most exposed. 

W-2s, 1099s, prior-year returns, and identity documents contain nearly everything criminals need to commit tax fraud or identity theft. And increasingly, scammers don’t need to break into systems to get them. They rely on rushed filers, familiar workflows, and convincing messages that blend into tax season noise. 

The good news: securing your tax documents doesn’t require expensive tools or technical expertise. With a few deliberate steps, you can dramatically reduce your risk before anything leaves your device. 

Why Scammers Want Your Tax Documents

Tax documents are valuable because they’re complete.A single W-2 includes your full name, Social Security number, employer information, and income data. Combined with other files, like a prior return or ID scan, that’s enough to: 

  • File a fraudulent tax return 
  • Open new credit accounts 
  • Access financial services 
  • Sell your identity on criminal marketplaces 

That’s why tax-related phishing and document theft spike every filing season. Many scams don’t look like scams at all. They look like routine requests, delivery notices, or “quick questions” from someone you already trust. 

How to Safely Handle and Share Tax Documents 

Tax forms contain some of the most sensitive personal information you have. Taking a few precautions when storing and sharing them can reduce the risk of identity theft and tax fraud. 

Store Your Tax Documents Securely 

Before sending anything to an accountant or tax service, make sure your files are organized and stored safely. 

Use a single secure folder
Create one folder, on your device or in a trusted private cloud service account, specifically for tax documents. Avoid scattering files across downloads, email attachments, and screenshots. 

Rename files clearly
Use descriptive names such as “2025_W2_EmployerName.pdf” so you can easily identify documents without opening multiple files or re-downloading forms. 

Avoid public Wi-Fi
If you’re downloading tax documents, do it on a secure home network whenever possible. Public Wi-Fi can increase the risk of interception. If you must connect in public, using a trusted VPN adds another layer of protection. 

Watch for Tax-Season Phishing Scams 

Many tax scams don’t target software, they target people. 

Common examples include: 

  • Emails pretending to be from the IRS asking you to “verify” information 
  • Messages that appear to come from your employer requesting a copy of your  W2 
  • Fake tax portals asking you to re-upload documents 
  • Urgent messages claiming there is a problem with your return 

These scams often arrive when you’re already expecting tax-related communication, which makes them easier to trust. 

Important: The IRS does not initiate contact by email, text message, or social media to request personal or financial information. 

Use Secure Ways to Share Tax Documents 

Email attachments are convenient, but they can also expose sensitive information. 

Safer options include: 

  • secure client portal provided by your accountant or tax preparer 
  • Encrypted file-sharing services 
  • Password-protected documents sent through a secure channel 

If you must email a document, avoid sending the password in the same message. 

Verify Requests Before Sending Documents 

Even if a request looks legitimate, pause before sharing sensitive files. 

Ask yourself: 

  • Did I expect this request? 
  • Is the sender using their normal contact method? 
  • Does the message create urgency or pressure? 

If something seems unusual, verify the request through a separate channel, such as calling the person directly or starting a new email thread. 

Secure the Devices You Use to File 

Protecting tax documents also means protecting the device where they’re stored. 

Before filing your taxes: 

  • Install the latest software updates on your computer and phone 
  • Enable automatic updates when possible 
  • Use security tools that can flag malicious links, fake websites, and suspicious messages, like McAfee’s WebAdvisor (free download here)

Tax scams increasingly arrive through text messages and social media, not just email, so protection needs to cover the places scammers actually reach you. 

File Early and Watch for Warning Signs 

Filing early reduces the opportunity for scammers to file a fraudulent tax return in your name. 

After filing: 

  • Watch for IRS notices you didn’t expect 
  • Monitor financial accounts for unfamiliar activity 
  • Be cautious of follow-up messages claiming problems with your return 

If something feels off, investigate before responding. 

Step-by-Step: How to Encrypt Tax Documents Before Sending Them 

Step  What to Do  Why It Matters 
1. Put all tax files into one folder  Gather your W-2s, 1099s, receipts, PDFs, and spreadsheets in one folder.  Keeps you organized and prevents accidentally leaving something unprotected. 
2. Convert photos into PDFs (if needed)  If documents are photos, save them as a PDF using your phone scanner app or printer settings.  PDFs are easier to encrypt and share securely than image files. 
3. Combine files into one ZIP folder  On your computer, select all files → right click → Compress / Zip.  Creates a single package you can protect with a password. 
4. Add a password to the ZIP file  Choose the “Encrypt” or “Password Protect” option when creating the ZIP file.  Password protection helps prevent unauthorized access if the file is intercepted. 
5. Use a strong password  Use at least 12 characters with a mix of letters, numbers, and symbols.  Weak passwords can be cracked quickly. 
6. Rename the file to something generic  Use a name like “Documents_2025.zip” instead of “Taxes_W2_SSN.zip.”  Avoids exposing sensitive info in the file name itself. 
7. Send the encrypted file through a secure method  Upload via your tax preparer’s secure portal or share through a secure cloud link.  Email attachments can be risky if the wrong person gains access. 
8. Send the password separately  Text or call the password—don’t include it in the same email as the file.  If someone intercepts the email, they won’t have both pieces. 
9. Confirm the recipient received it securely  Ask them to confirm download and access.  Prevents re-sending sensitive documents multiple times. 
10. Delete extra copies once filing is done  Remove unneeded copies from desktop, downloads folder, and email attachments.  Reduces the chance of future exposure if your device is compromised. 

What to Do If You Think Your Tax Information Was Exposed 

If you believe your tax documents were shared with the wrong party or compromised: 

  1. Stop further communication immediately 
  2. Contact your accountant or tax service 
  3. Notify the IRS if sensitive information was exposed 
  4. Monitor credit and financial accounts closely 
  5. Run a security scan on your device, check out our free trial 

Acting quickly can limit damage and help prevent long-term fallout. 

Final Thoughts

Securing your tax documents doesn’t require perfection, just intention. 

By slowing down, using safer sharing methods, and staying alert to tax-season scams, you can protect yourself before problems start. In a season where everyone feels rushed, a few extra minutes can save months of cleanup later. 

McAfee helps protect your identity, devices, and personal information so tax season doesn’t become scam season. 

Frequently Asked Questions 

Q: Is it safe to email tax documents to my accountant? 

A: Email is not the safest option. Secure portals or encrypted file-sharing tools are preferred for sensitive documents like W-2s and tax returns. 

Q: How do W-2 phishing scams work? 

A: Scammers impersonate employers or tax authorities to trick people into sending W-2s or personal information, often using urgent or official-looking messag 

Q: Can scammers file taxes using my W-2? 

A: Yes. With enough personal information, criminals can file fraudulent returns or commit identity theft. 

Q: How can I tell if a tax message is fake?
A: Be cautious of unsolicited requests, urgent language, unfamiliar links, or requests for documents outside normal filing workflows. 
Q: What’s the safest way to share tax documents online? 

A: Use secure portals, encrypted file-sharing, and verified communication channels. Avoid public Wi-Fi and unprotected email attachments.

New Research: Hackers Are Using AI-Written Code to Spread Malware

18 March 2026 at 21:48

McAfee Labs has uncovered a widespread malware campaign hiding inside fake downloads for things like game mods, AI tools, drivers, and trading utilities. 

In January 2026, researchers observed 443 malicious ZIP files impersonating software people might actively search for online. Across those files, McAfee identified 48 malicious WinUpdateHelper.dll variants used to infect devices. The campaign was spread through a mix of file-hosting and content delivery services, including Discord, SourceForge, FOSSHub, and mydofiles[.]com. 

What makes this campaign especially notable is that some parts of it appear to have been built with help from large language models (LLMs). McAfee researchers found signs that certain scripts likely used AI-generated code, which may have helped the attackers create and scale the campaign faster. 

That does not mean AI created the whole operation on its own. But it does suggest AI may be helping cybercriminals lower the effort needed to build malware and launch attacks. 

Want the full research? Dive in here. 

We break down the top takeaways below. 

What McAfee Found 

Finding  What it means 
443 malicious ZIP files  Attackers created many different fake downloads to reach more victims 
48 malicious DLL variants  The campaign used multiple versions of the malware, not just one file 
1,700+ file names observed  The same threat was repackaged under many different names to look convincing 
17 distinct kill chains  Researchers found multiple attack flows, but they followed a similar overall pattern 
Hosted on familiar platforms  The malware was distributed through services users may recognize, including Discord and SourceForge 
AI-assisted code suspected  Some scripts contained explanatory comments and patterns that strongly suggest LLM assistance 
Cryptomining and additional malware observed  Infected devices could be used to mine cryptocurrency or receive more malicious payloads 

What Is “AI-Written Malware”? 

In this case, “AI-written malware” does not mean an AI system independently invented and launched the attack. 

Instead, McAfee Labs found evidence that the attackers very likely used AI tools to help generate some of the code used in the campaign, especially in certain PowerShell scripts. 

Put simply: 

Term  Plain-English meaning 
Large language model (LLM)  An AI system that can generate text and code based on prompts 
AI-assisted malware  Malware where attackers appear to have used AI tools to help write or structure parts of the code 
Vibe coding  A style of coding where someone describes what they want and an AI does much of the writing 

This matters because it can make malware development faster, easier, and more scalable for attackers. 

Figure 1: Attack Vector
Figure 1: Attack Vector

 

How The Fake Download Attack Works 

The attack begins when someone searches for software online and downloads what looks like the tool they wanted. 

That tool might appear to be a game mod, AI voice changer, emulator, trading utility, VPN, or driver. But behind the scenes, the ZIP archive includes malicious components that start the infection. 

Step  What happens 
1. A user downloads a fake file  The ZIP archive is disguised as something useful or desirable, such as a mod menu, AI tool, or driver 
2. The file appears normal at first  In some cases, the package includes a legitimate executable so it feels more convincing 
3. A malicious DLL is loaded  A hidden malicious file, often WinUpdateHelper.dll, starts the real attack 
4. The user is distracted  The malware may display a fake “missing dependency” message and redirect the user to install unrelated software 
5. A PowerShell script is pulled from a remote server  While the user is distracted, the malware contacts a command-and-control server and runs additional code 
6. More malware is installed  Depending on the sample, the device may receive coin miners, infostealers, or remote access tools 
7. The infected device is abused for profit  In many cases, attackers use the victim’s system resources to mine cryptocurrency in the background 

What Kinds of Files Were Used as Bait 

McAfee found that the attackers cast a very wide net. The malicious ZIP files impersonated many types of software, including: 

Bait category  Examples 
Gaming tools  game mods, cheats, executors, Roblox-related tools 
AI-themed tools  AI image generators, AI voice changers, AI-branded downloads 
System utilities  graphics drivers, USB drivers, emulators, VPNs 
Trading or finance tools  stock-market utilities and related downloads 
Fake security or malware tools  fake stealers, decryptors, and other risky-looking utilities 

That broad range is part of what made the campaign effective. It was designed to catch people already looking for shortcuts, unofficial tools, or hard-to-find software. 

Why McAfee Researchers Believe AI Was Used 

One of the strongest clues came from the comments inside some of the attack scripts. 

McAfee researchers found explanatory comments that looked more like AI-generated instructions than the kind of shorthand attackers usually leave for themselves. In one example, a comment referred to downloading a file from “your GitHub URL,” which suggests the code may have come from a generated template and was not fully cleaned up before use. 

These details do not prove every part of the campaign was AI-made. But they do support McAfee’s assessment that certain components were likely generated with help from large language models. 

What Happens on an Infected Device 

In many cases, the malware was used to turn victims’ computers into quiet crypto-mining machines. 

McAfee observed mining activity involving several cryptocurrencies, including: 

  • Ravencoin 
  • Zephyr 
  • Monero 
  • Bitcoin Gold 
  • Ergo 
  • Clore 

Some samples also downloaded additional payloads such as SalatStealer or Mesh Agent. 

For victims, that can mean: 

Possible effect  What it may look like 
Slower performance  apps lag, games stutter, system feels unusually sluggish 
High CPU or GPU usage  fans run constantly, laptop gets hot, battery drains faster 
Background malware activity  unknown processes, suspicious downloads, unexpected behavior 
Potential data theft  if an infostealer or remote access tool is installed 

McAfee was also able to trace several Bitcoin wallets tied to the campaign. At the time of the report, those wallets held about $4,536 in Bitcoin, while total funds received were approximately $11,497.70. Researchers note the real total could be higher because some of the currencies involved are harder to trace. 

Who Was Targeted Most 

This campaign was observed most heavily in: 

  • United States 
  • United Kingdom 
  • India 
  • Brazil 
  • France 
  • Canada 
  • Australia 

That does not mean users elsewhere were unaffected. These were simply the countries where researchers saw the highest prevalence. 

Figure 2: Geographical Prevalence 
Figure 2: Geographical Prevalence 

  Red Flags To Watch For 

Even though the campaign used advanced techniques, the warning signs for users were often familiar. 

Red flag  Why it matters 
You found the file through a random link  Unofficial forums, Discord links, and file-hosting pages are common malware delivery paths 
The download is a ZIP for something sketchy or unofficial  Cheats, cracks, mod tools, and unofficial utilities carry higher risk 
You get a “missing dependency” message  Attackers may use this to push a second download while the real infection happens in the background 
The file name looks right, but the source feels wrong  Familiar names can be faked easily 
Your PC suddenly slows down or overheats  Hidden cryptominers often abuse system resources 
You notice new, unrelated software installed  The campaign sometimes used unwanted software installs as a distraction 

How To Stay Safe From Malware Hidden in Fake Downloads 

This campaign is a reminder that not every convincing file is a safe one. A few habits can reduce your risk significantly. 

Safety step  Why it helps 
Download software only from official sources  This lowers the chance of accidentally installing a trojanized file 
Avoid cheats, cracks, and unofficial mods  These categories are common bait for malware campaigns 
Be skeptical of dependency prompts  Unexpected requests to install helper files or missing components can be part of the attack 
Keep your security software updated  Current protection can help detect known threats and suspicious behavior 
Pay attention to system performance  A suddenly hot, loud, or slow PC may be a sign something is running in the background 
Review what you download before opening it  Even a familiar file name does not guarantee a file is legitimate 

McAfee helps protect against malware threats like these with multiple layers of security, including malware detection and safer browsing protections designed to help stop risky downloads before they can do damage. 

What To Do If You Think You Opened One of These Files 

If you think you downloaded and ran a suspicious file like one described in this campaign: 

Action  Why it matters 
Disconnect from the internet  This can help interrupt communication with attacker-controlled servers 
Run a full security scan  A trusted scan can help identify malicious files and behavior 
Delete suspicious downloads  Remove the file and avoid reopening it 
Check for unfamiliar software or startup items  The infection may have installed additional components 
Change important passwords from a clean device  This is especially important if data-stealing malware may have been involved 
Monitor accounts for unusual activity  Keep an eye on email, banking, and other sensitive accounts 

If your computer continues acting strangely after a scan, it may be worth getting professional help. 

What This Means for the Future of Malware 

This campaign highlights how cybercrime is evolving. 

The core risk is not just fake downloads. It is the fact that attackers are using AI tools to help generate code, create variations, and speed up parts of the malware development process. 

That can make campaigns like this easier to scale and harder to ignore. 

For everyday users, the takeaway is simple: if a file seems unofficial, rushed, or too good to be true, pause before opening it. A fake download may look like a shortcut, but it can quietly turn your device into a target.

1 in 3 Has Experienced a Betting Scam. What March Madness Fans Should Know

17 March 2026 at 12:55

Whether you’re a hardcore basketball fan or the office colleague who gets roped into filling out a bracket every year, March Madness is the season for brackets, office pools, and last-minute picks. 

More than half of Americans (57%) plan to watch the NCAA basketball tournament, and 55% say they participate in some kind of betting or bracket activity during March Madness, from office pools to licensed sportsbook wagers.  

But where there’s excitement and money, scammers aren’t far behind. 

New research from McAfee finds that 1 in 3 Americans (32%) say they’ve experienced a betting or gambling scam, and 24% say they’ve lost money to one, with victims losing an average of $547. 

Big events like March Madness create the perfect storm: massive attention, constant betting promotions, and fans searching online for predictions, tips, and an edge. 

Scammers know it, and they’re exploiting the moment. 

This example shows an incredible realistic, but fake, Fanduel site created by scammers to impersonate the real thing.
This example shows an incredibly realistic, but fake, FanDuel site created by scammers to impersonate the real thing.

Why March Madness is Prime Time for Betting Scams 

Sports betting promotions are everywhere during major events like March Madness. 

According to McAfee research, 82% of Americans say they’ve seen sports betting promotions or offers in the past year, often on social media, streaming broadcasts, and sports websites. 

That flood of promotions makes it easier for scams to blend in with legitimate content. 

Many scams start the same way legitimate offers do, through messages, ads, or links promising bonuses or tips. But once someone clicks or responds, the situation can escalate quickly. 

For example: 

  • 42% of Americans say they’ve been asked to click a link sent via email tied to a betting offer 
  • Others report links sent through social media messages or text messages directing them to betting sites, apps, or private betting groups 

In many cases, victims are then asked to send money to unlock winnings, activate accounts, or access premium betting picks. 

The payout rarely exists. 

The Most Common Betting Scams Fans Encounter 

Betting scams come in several forms, but many follow familiar patterns. 

Here are some of the most common tactics reported in McAfee’s research: 

Scam Type  Definition  How It Works  Red Flags 
Guaranteed Win Scam  A betting scam where someone promises a “guaranteed win,” “sure bet,” or “can’t lose” outcome in exchange for money, clicks, or sign-ups. According to McAfee Findings, about 1 in 6 Americans say they’ve received these kinds of messages, which are designed to lure fans looking for an edge.  Scammers send private messages, emails, or social posts claiming they have insider knowledge or a lock on a game. The goal is usually to get the victim to pay for picks, join a private group, or click a malicious link.  Claims that a bet is guaranteed, pressure to act fast, requests for payment to access picks, and promises that sound risk-free. 
Fake Free Bet Promotion Scam  A scam that pretends to offer bonus bets, deposit matches, or free credits through a fake sportsbook promotion.  The victim sees what looks like a real sportsbook offer, often through social media, email, or text. Clicking may lead to a fake site that steals login details, payment information, or deposits.  Unfamiliar brand names, unofficial links, urgent sign-up language, and promotions that seem unusually generous. 
Winnings Release Fee Scam  A scam where a victim is told they have winnings waiting, but must first pay a fee, deposit, or processing charge to collect them.  The scammer claims the user has won money, then invents a reason payment is required before the funds can be released. Once the fee is sent, the payout never arrives.  Requests to pay before receiving winnings, vague “processing” or “verification” fees, and pressure to send money immediately. 
Fake Betting App or Website Scam  A scam involving a fraudulent app or website designed to look like a real sportsbook or betting platform.  Victims are directed to a fake platform where they may create an account, enter personal information, or deposit money. The site may appear legitimate, but withdrawals are blocked or impossible.  Slightly misspelled URLs, strange app download paths, poor website quality, and platforms that make deposits easy but withdrawals difficult. 
Sportsbook Impersonation Scam  A scam in which someone pretends to represent a legitimate betting platform or sportsbook support team.  The scammer contacts the victim claiming there is an issue with an account, a bonus, or winnings. They then ask for login credentials, payment details, or personal information.  Requests for passwords, bank details, or identity information; unexpected outreach; and messages pushing you to resolve an “account issue” through a link. 
Fake Insider Tip Scam  A scam that uses claims of insider information, fixed games, or special access to make a betting offer sound exclusive and trustworthy.  Scammers position themselves as experts, insiders, or connected sources who can help the victim beat the odds. The real goal is usually payment, account access, or enrollment in a scam betting channel.  Claims of fixed outcomes, “insider” knowledge, exclusive access, and offers that rely on secrecy or urgency. 
Celebrity or Influencer Endorsement Scam  A betting scam that uses fake or misleading celebrity, athlete, or influencer endorsements to make an offer seem legitimate.  Scammers create ads, videos, or posts that appear to feature a public figure recommending a betting platform, app, or tip service. In some cases, AI-generated content makes these endorsements look more convincing.  Endorsements that seem off-brand, videos or graphics that look unnatural, unfamiliar accounts, and promotions tied to fake urgency or suspicious links. 
Private Betting Group Scam  A scam that tries to move betting conversations into private channels like WhatsApp, Telegram, or Signal.  After initial contact on social media or another public platform, the scammer encourages the victim to join a private group for “exclusive picks,” “VIP bets,” or “premium insights.” These groups are often used to pressure victims into sending money or clicking malicious links.  Pressure to move off-platform quickly, promises of VIP access, requests for payment to join, and little proof that the group is legitimate. 

Who Is Most Likely to Encounter Betting Scams 

McAfee’s research found that Americans under 45 are significantly more likely to encounter betting scams, with 44% saying they’ve experienced one compared with 19% of those over 45. 

Men also report higher exposure, with 40% saying they’ve experienced a betting scam, compared with 25% of women.  

Men and younger adults are also more likely to participate in brackets, fantasy sports, or sportsbook betting, the same spaces where scams often appear.

AI Is Making Betting Scams Harder to Spot 

Artificial intelligence is beginning to change how scams look and sound. 

About 1 in 5 Americans say they’ve encountered betting scams that appeared more realistic because of AI, and 27% believe they’ve seen AI-generated betting content such as fake promotions, images, or videos.  

Among those who encountered AI-driven scams: 

  • 58% reported AI-generated images or graphics in betting ads 
  • 57% saw AI-written messages that sounded natural or personalized 
  • 45% encountered fake celebrity or influencer endorsements 
  • 36% interacted with chatbots posing as betting experts or support agents  

As these tools improve, scam messages are becoming smoother, more convincing, and harder to distinguish from legitimate promotions. 

Safety Check  What To Do 
Be skeptical of “guaranteed wins”  No bet is risk-free. Ignore messages promising sure bets, insider picks, or guaranteed outcomes. 
Use only licensed sportsbooks  Stick to official betting apps and well-known sportsbooks. Avoid unfamiliar websites or apps. 
Don’t click betting links from unknown messages  If you receive a betting offer via email, text, or social media, go directly to the official site instead of clicking the link. 
Never pay fees to unlock winnings  If someone says you must send money to claim winnings or activate a betting account, it’s almost certainly a scam. 
Be cautious of private betting groups  Invitations to “VIP betting groups” on apps like Telegram or WhatsApp are often used to promote scam picks or collect payments. 
Protect your accounts  Use strong passwords and turn on two-factor authentication wherever possible. Try our free strong password generator. 
Use scam detection tools  Tools like McAfee’s Scam Detector can flag suspicious links, websites, and messages before you engage. 

March Madness is meant to be fun, filling out brackets, debating picks with friends, and cheering for the next big upset. Betting can be part of that excitement, but it’s worth remembering that scammers are watching the tournament too. 

A simple rule of thumb can go a long way: if a betting offer promises guaranteed wins, asks for money upfront, or pushes you to act quickly, take a step back and verify it first.  

The safest plays are the ones where you slow down, stick to trusted platforms, and keep your personal information protected.
