Let me blow your mind real quick: When you use Remote Desktop (RDP), Windows secretly takes screenshots of what you are doing. It’s called the RDP Bitmap Cache. To make the connection faster, Windows saves small tiles (images) of the remote screen to your hard drive in a bin

Multiple, serious security vulnerabilities found in the Rust clone of Sudo — which shipped with Ubuntu 25.10 (the most recent release). Not little vulnerabilities: We’re talking about the disclosure of passwords and total bypassing of authentication. In fact, we’re getting new
