Stop installing these 4 apps—Windows does it all now

Windows has evolved to integrate functionalities that were once reliant on third-party applications, such as native support for ZIP files introduced in Windows ME in 2000, and the ability to open and create RAR, TAR, and 7z formats directly from File Explorer. Features like Storage Sense have replaced the need for tools like CCleaner by allowing users to manage temporary files more easily, and the effectiveness of Windows Defender has reduced the necessity for third-party antivirus solutions. Additionally, modern Windows can mount ISO files directly, eliminating the need for applications like Daemon Tools. The trend of operating systems adopting features from third-party applications, known as "Sherlocking," reflects a response to user demands while still allowing for optional third-party solutions.

Fix: “Cannot Complete the Archive Extraction” in Windows

Users may encounter the error message “Cannot complete the archive extraction wizard” when using the built-in Windows extractor for ZIP or RAR files, indicating limitations of this tool. Common issues include damaged archives, incompatible compression methods, long file paths, restricted extraction locations, insufficient disk space, or interruptions from security software. To address these challenges, users can: 1. Use third-party extractors like 7-Zip, WinRAR, or PeaZip for better compatibility and success rates. 2. Check if the archive is corrupted and re-download it if necessary, ensuring the download completes fully. 3. Shorten the file path by moving the archive to a simpler directory to avoid exceeding path limits. 4. Temporarily disable antivirus or real-time protection, as it may interrupt the extraction process. If problems persist, testing the archive on a different PC can help determine if the issue is with the archive or the current system. If the archive fails on another computer, it is likely corrupted or incomplete, requiring a fresh download or replacement.

Attackers Use Malformed ZIP Archives to Evade Antivirus and EDR Tools

Cybersecurity researchers at the CERT Coordination Center (CERT/CC) have identified a new evasion technique, VU#976247, used by threat actors to exploit malformed ZIP archives and bypass Antivirus (AV) and Endpoint Detection and Response (EDR) systems. Attackers manipulate the internal headers of ZIP files, particularly altering the compression method field, which causes security tools to fail in analyzing the malicious payload. While some security products may flag the modified files as corrupted, they often do not detect the underlying malicious code. Standard extraction tools typically trust the tampered metadata and may return errors, leaving the hidden payload undisclosed. Attackers use custom malware loaders to extract and execute the malicious data, circumventing traditional AV detection. Cisco has been confirmed as affected, while other vendors, including AhnLab, Avast, Bitdefender, and Avira, have an “Unknown” status regarding their vulnerability. To mitigate this threat, organizations should enhance archive handling processes, avoid relying solely on declared metadata, adopt aggressive detection modes, flag metadata inconsistencies, and consult with AV and EDR providers about vulnerabilities.

Malformed ZIP Files Allows Attackers to Bypass Antivirus and EDR Detections

A vulnerability identified as CVE-2026-0866 allows malicious actors to exploit malformed ZIP headers to bypass antivirus and Endpoint Detection and Response (EDR) systems. This flaw occurs because most security solutions rely on metadata within ZIP archives to scan and process files. When the compression method field is altered, security scanners may fail to decompress the archive correctly, resulting in a false negative and leaving the malicious payload undetected. Attackers can then use a custom loader to access the embedded malicious data, circumventing standard extraction tools. Cisco has been confirmed as affected by this vulnerability, while nearly 30 other security vendors have not disclosed their status. The cybersecurity community is urged to evolve scanning methodologies, including not relying solely on declared metadata and implementing aggressive detection modes. Organizations should verify their antivirus and EDR solutions for vulnerability to CVE-2026-0866 and monitor for custom loaders.

Microsoft Reveals ClickFix Campaign Using Windows Terminal to Deploy Lumma Stealer

Microsoft revealed a social engineering campaign named ClickFix that exploits the Windows Terminal application to deploy Lumma Stealer malware. Detected in February 2026, this campaign instructs users to access Windows Terminal using the Windows + X → I shortcut, enhancing its perceived legitimacy. Attackers evade detection by manipulating users into executing harmful commands through deceptive prompts. The attack chain involves pasting a hex-encoded command into Windows Terminal, which opens additional Terminal and PowerShell instances, leading to a PowerShell process that decodes a script. This process downloads a ZIP payload containing a renamed 7-Zip binary, which extracts files and initiates a multi-stage attack, including retrieving payloads, establishing persistence, configuring Microsoft Defender exclusions, exfiltrating data, and deploying Lumma Stealer by injecting it into "chrome.exe" and "msedge.exe." Lumma Stealer targets browser artifacts to harvest credentials. A secondary attack pathway involves downloading a batch script that writes a Visual Basic Script to the Temp folder and connects to Crypto Blockchain RPC endpoints, also using QueueUserAPC() for code injection into browsers to extract data.

Your BitLocker-secured Windows PC isn’t so secure after all – unless you do this

Microsoft's BitLocker encrypts personal files on Windows hard drives to protect against unauthorized access in case of loss or theft. The BitLocker recovery key is essential for decrypting data, but Microsoft has confirmed it will comply with valid legal requests for access to these keys if they are stored in the cloud. This was highlighted during an FBI investigation in Guam, where Microsoft provided recovery keys related to a COVID unemployment fraud case. Microsoft receives about 20 requests for BitLocker keys annually, but many cannot be fulfilled if users do not store their keys in the cloud. The Guam case is the first known instance of Microsoft providing encryption keys to law enforcement, contrasting with a previous request from the FBI in 2013 that was declined. Users can choose to store their keys locally or in Microsoft's cloud, but storing them in the cloud carries risks of unauthorized access. For optimal security, it is recommended to save the recovery key on a USB stick or external drive, encrypting the file if necessary, and avoiding cloud storage. Users should check their BitLocker settings in Windows 11 or 10 to manage their recovery keys and consider removing any keys stored in the cloud.
