Microsoft Edge Stores Passwords in Process Memory, Posing Risk

, ,

Security researcher Tom Jøran Sønstebyseter Rønning revealed that Microsoft Edge stores all saved passwords in cleartext in process memory, even when sites are not actively visited, allowing anyone with administrative privileges to extract these passwords and potentially escalate attacks within corporate environments. Microsoft considers this behavior “by design,” citing trade-offs between performance, usability, and security, but experts warn it poses significant risks, especially in shared or virtualized settings, and recommend organizations limit reliance on browsers for password storage and enforce strict access controls.

Critical Apache HTTP/2 Flaw (CVE-2026-23918) Enables DoS and Potential RCE

,

The Apache Software Foundation has released updates to fix a critical vulnerability (CVE-2026-23918) in Apache HTTP Server 2.4.66 that allows denial-of-service (DoS) attacks and potential remote code execution (RCE) via a double-free bug in HTTP/2 protocol handling. The flaw can be exploited by sending specific HTTP/2 frames, with the RCE path particularly feasible on systems using the default Apache Portable Runtime mmap allocator, leading to high risk for widely deployed servers.

I Left Port 22 Open on the Internet for 54 Days. Here’s Who Showed Up.

In a 54-day experiment, a honeypot mimicking an Ubuntu SSH server was left open on port 22, recording over 269,000 connection attempts from 7,556 unique IPs. The study revealed a constant flood of mostly automated attacks scanning for weak passwords, with a small fraction of sophisticated attackers deploying advanced techniques, including targeted crypto node intrusions; the findings underscore the relentless and noisy nature of internet scanning and the importance of robust SSH security practices.
