I have been writing about TVs and home theater tech for the better part of a decade. These are the best TVs ZDNET has tested from brands like LG, Samsung, and Hisense.
Comcast has folded its Wi-Fi-based intruder detection feature into Xfinity Shield, a repackaged bundle of physical and cybersecurity offerings. The US telco launched WiFi Motion in 2025. Xfinity Shield also includes cybersecurity protections built into the Xfinity Gateway router. The Wi-Fi sensing technology harnesses the radio waves beamed around a user's home to detect motion and potential intruders. "Using Xfinity Gateway intelligence, WiFi Motion detects changes in the home's radio frequency signal between the Xfinity Gateway and a Wi-Fi connected device, then sends instant notifications to customers through the Xfinity app when unexpected activity is detected," Comcast said. "It provides an added layer of awareness without recording video, capturing images or identifying individuals." The company does not consider this a home security service, merely a feature, because it is not managed by a dedicated security provider. Not every connected device can support the sensing feature. It uses the Xfinity Gateway, Xfinity Wi-Fi extenders, and up to three other compatible devices around the home. Crucially, these devices must be stationary. Think thermostats and home speakers, not smartphones or toothbrushes. Comcast advises users to position the router and extenders so that their signals pass through the areas where they want to detect motion. Open spaces such as hallways work best, and the company urges routine testing to ensure coverage is maintained. A setting in the Xfinity app allows WiFi Motion to ignore small pets. Animals weighing around 18 kg (40 pounds) or less will not trigger alerts when this setting is enabled, and the app warns this may also exclude small children. Customers can also adjust the sensitivity of the motion detection, choosing from low, medium, and high-sensitivity modes. Comcast says the latter works best in single-family, detached homes, whereas those who share walls with neighbors may want to choose the less-sensitive settings to avoid meaningless notifications. The telco also assured customers that WiFi Motion does not track individuals or their precise movements, and cannot identify specific people. It added that it "does not monitor motion and/or notifications generated by the service." The small print, which also accompanied the 2025 launch, suggests the service may not be quite as private as the marketing implies. Comcast states: "Subject to applicable law, Comcast may disclose information generated by your WiFi Motion to third parties without further notice to you in connection with any law enforcement investigation or proceeding, any dispute to which Comcast is a party, or pursuant to a court order or subpoena." Comcast does not specify what information may be disclosed or which "third parties," beyond law enforcement, might receive it. How it works Users can establish "sensing areas" by placing Wi-Fi devices around parts of the home with regular foot traffic. Comcast describes each sensing area as a long oval extending between two connected devices. Sensing areas can be established through walls separating rooms, although in two-storey or multi-storey homes, the telco encourages customers to avoid placing Wi-Fi equipment directly above or below each other. "Motion is detected within the sensing area when movement disrupts the wireless signals that travel between your Xfinity WiFi equipment and selected WiFi-connected devices within the sensing area," said Comcast. "Notifications will be sent only when motion disrupts the wireless signals in the sensing area between the WiFi equipment and your connected devices." Not a novel feature Comcast is the latest, but not the first, to harness Wi-Fi radio waves for motion detection. Companies such as Cognitive Systems and Origin Wireless have been developing other uses for wireless signals. Beyond domestic intruder alerts, the technology can measure occupancy and foot traffic in commercial buildings, helping operators reduce energy consumption and make better use of leased space. Wireless signals can also be used to support caregivers in places like assisted living centers. Wi-Fi transmissions can help track activity patterns and build a greater understanding of patients' fall risks, for example. Boffins began working on an official Wi-Fi sensing standard in 2020. Following a draft published by the IEEE in 2023, the 802.11bf standard was ratified in 2025. Major chipmakers including MediaTek, Qualcomm, and others are now working on embedding the standard into their Wi-Fi 7 chips and beyond. SaaS biz Plume, which provides smart home services to consumers and ISPs, has offered Wi-Fi sensing since 2020, around the time the 802.11bf working group began devising the standard. ®
A previously unreported cyber espionage operation dubbed SilkParasite has been observed targeting government bodies in Central Asia.
The intrusion set makes use of seven remote access tool (RAT) families, five of which have never been previously documented: DriveSilkRAT, CookiETagRAT, NomadRAT, GoginRAT, and NodeEdgeRAT. SilkParasite, first discovered in late 2025, is assessed to be a
I finally found some time to organize my notes on secure boot, remote attestation, measured boot and in general embedded security.
This is not ground breaking zero-day research but I figured some of you might like a good story. Good here is obviously subjective but I felt like it came out quite readable.
This blog builds heavily on public research so as already stated at the end of article if you liked some particular section, show the respective person some love :)

Cybersecurity researchers at Hunt.io have disclosed details of a campaign that they say compromised more than 14,530 Dahua devices between June 17 and July 22, 2026, using credential attacks, two authentication-bypass flaws, and a peer-to-peer (P2P) relay technique.
The activity, codenamed Operation CameraSwarm, was reconstructed from a 407 MB exposed working directory containing 2,616 files
Most email defenses still do the job they did a decade ago. Scan the message, look for something malicious, block it. That worked when the danger sat in the payload, a bad link or an attachment. It stopped working when the danger moved into the message's intent, and it is failing now that the sender is no longer a person.
From Bad Content to Bad Intent to AI on Both Sides
Phishing 1.0 was bad
Cybersecurity researchers have flagged a global cybercrime operation that abuses thousands of hacked WordPress websites as infrastructure to disseminate malware, commandeer infected hosts, store stolen documents, screenshots, and activity logs created to track the status of the activity.
"The operation doesn't rely on a single piece of malware, but on a whole toolkit of criminal software
Even if it has impressive out-of-the-box color, your new (or old) TV can always benefit from a few simple tweaks to get the best color accuracy possible.
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday added four critical vulnerabilities to its Known Exploited Vulnerabilities (KEV) catalog, stating they are being exploited in the wild.
The shortcomings added to the KEV catalog are listed below -
CVE-2026-65400 (CVSS score: 9.8) - An improper authentication vulnerability impacting Apple macOS that could allow an
The people-search tool ClarityCheck says its reverse image search service is “private and secure”—but it left a database containing more than 9 million image files exposed.
Flock’s surveillance cameras have already sparked outrage. WIRED reconstructed its next-generation AI system, already in use by some police, to confirm it goes much further than tracking license plates.
Mozilla has finally released the beta of Firefox Smart Window. I ran it through its paces and found features that might lure me back to my old favorite browser.
