linux hosting security

This tag covers security threats specific to Linux hosting environments, with a focus on stealthy attack techniques. Recent content highlights how threat actors use HTTP cookies to control PHP webshells, a method that evades traditional detection by hiding malicious commands in cookie headers. Microsoft's research shows this technique is used across web requests, scheduled tasks, and background workers, making it a persistent threat. Discussions emphasize the need for layered defenses beyond single detection points, as cookie-based control planes are less scrutinized than query strings or request bodies. The tag is relevant for system administrators, security professionals, and anyone managing Linux web servers who needs to understand emerging attack vectors and improve their security posture.
