Windows 11’s Recall tool has been cracked open again, and Microsoft doesn’t see that as a problem

Alexander Hagenah has developed a tool called TotalRecall Reloaded that exploits a vulnerability in Microsoft's AI feature, Recall, which manages data. Recall was designed to store AI-generated insights but was found to potentially store sensitive information in plain text, prompting Microsoft to delay its rollout. The vulnerability lies in AIXHost.exe, which lacks essential security measures, allowing unauthorized processes to extract sensitive data, such as decrypted screenshots and metadata, after user authentication via Windows Hello. Microsoft has downplayed the risks, asserting that existing security controls mitigate unauthorized access. TotalRecall Reloaded is available on GitHub for further exploration.

Microsoft adds Windows protections for malicious Remote Desktop files

Microsoft has introduced new security measures for Windows 10 and Windows 11 to protect against phishing attacks that exploit Remote Desktop Protocol (RDP) connection files. These updates, part of the April 2026 cumulative updates (KB5082200, KB5083769, and KB5082052), include a one-time educational prompt for users upon first opening an RDP file, requiring acknowledgment of the associated risks. Subsequent attempts to open RDP files will display a security dialog with information about the file's publisher, the remote system address, and local resource redirections, with options disabled by default. If an RDP file is unsigned, a warning will indicate an "Unknown remote connection." These protections apply only to connections initiated through RDP files, not through the Windows Remote Desktop client, and can be temporarily disabled via the Windows Registry.

Security researchers find 213 vulnerabilities in Russia’s state-backed messaging app Max

Security researchers discovered 213 vulnerabilities in Max, Russia's state-backed messaging app, during a bug bounty initiative. This information was shared by Alexei Batyuk, CTO of Positive Technologies, at the Svyaz-2026 exhibition. The bug bounty program has been active since July 1, 2025, resulting in 288 accepted vulnerability reports and total payouts of nearly 22 million rubles. Common vulnerabilities could allow unauthorized access to user data through the manipulation of object identifiers. Max's press service claimed that user data is "reliably protected" and emphasized the importance of independent white-hat hackers in identifying vulnerabilities. Max was launched by VK in March 2025 and is being promoted by Russian authorities amid efforts to block other messaging platforms like Telegram and WhatsApp. The app has faced criticisms regarding user surveillance and security vulnerabilities.
