Microsoft Scrambles To Patch ShieldBreak Zero-Day Flaw In Windows Defender

A new exploit named ShieldBreak, developed by Nightmare-Eclipse, targets Microsoft Defender by allowing privilege escalation and bypassing previous security fixes related to the RoguePlanet vulnerability. ShieldBreak operates on Windows 11 25H2, its Canary channel, and Windows Server 2025, achieving a "100% success rate." Windows 10 may also be vulnerable, but the exploit is specifically designed for Windows 11. There is currently no patch for ShieldBreak, and users are advised to disable Microsoft Defender, implement two-factor authentication, and exercise caution with suspicious online activities. Malwarebytes has recommended its Premium Security antivirus as a temporary solution.

Best Malware Removal Tools of 2026: Tested on Infected PC

A hands-on evaluation was conducted to assess the effectiveness of various malware removal tools by deliberately infecting a PC and running six different cleanup tools. The recommended steps for users suspecting malware infection include disconnecting from the internet, installing an on-demand scanner, removing detected threats, rebooting the system, and changing passwords. The top malware removal tools identified were: 1. Malwarebytes Free: Quick scan in 2 minutes and 20 seconds; complete removal with no remnants. 2. Bitdefender: Quick scan in 1 minute and 4 seconds; complete removal confirmed. 3. Norton 360: Quick scan in 58 seconds; effective for severely compromised devices. 4. Avast One Free: Quick scan in 1 minute and 12 seconds; complete removal with ongoing protection. 5. McAfee: Full system scan took 16 minutes and 47 seconds; complete removal but slower than others. 6.

For Windows, Safe Mode with Networking is recommended for removal, while Mac users should use Activity Monitor to identify suspicious processes. Android users can utilize Safe Mode and Play Protect for scanning. A factory reset may be necessary if infections persist.

It achieved the highest malware detection rates, the fewest false alarms, and minimal impact on startup time.

PSA: Don’t trust that Chrome update popup

Users of Chromium-based browsers, including Google Chrome, Brave, and Opera, are experiencing deceptive pop-ups that falsely claim a "Critical Update Required" or "Update available." These notifications are part of a scam designed to trick users into downloading malware disguised as software updates. Clicking on these prompts can lead to the download of harmful scripts, such as .vbs or .exe files, which traditional antivirus software often fails to detect. The issue is linked to compromised browser extensions that fetch malicious scripts from external servers. A specific extension, QuickLens – Search Screen with Google Lens, has been identified as a source of these pop-ups and has been removed from the Web Store. Other extensions, like “Enable Right Click & Copy Smart Unlock + OCR,” have also been implicated despite their popularity. Users are advised not to click on any links or run downloaded files and to check their browser settings for legitimate updates, as well as to audit and disable suspicious extensions.

Fake popular sites offer a free app, instead take over PCs

A fraudulent website mimicking CNN's homepage is promoting a fake "CNN app" that is not affiliated with CNN. This site, along with others impersonating brands like Avast and Stremio, distributes a legitimate remote management tool called O&O Syspectr, which can grant attackers remote access to victims' computers. The installers for these counterfeit apps share the same account ID, indicating they are linked to the same malicious source. Users are misled into downloading these installers, which appear legitimate but allow unauthorized access to their systems. O&O Software has responded by disabling certain features for free accounts and monitoring for abuse. Users are advised to only download software from official sources and verify installer details before execution.
