Linux Proc Memory Credential Harvesting Tool
This rule detects attempts to harvest credentials from process memory on Linux systems. It specifically looks for HTTP traffic (flow:to_client,established) containing both the string "/proc/self/mem" and "password" (case-insensitive) within the file data. This combination suggests a tool or script is attempting to read memory for credential extraction, often associated with techniques like credential dumping.
