About

This rule monitors for manual memory dumping via the proc filesystem. The proc filesystem in Linux provides a virtual filesystem that contains information about system processes and their memory mappings. Attackers may use this technique to dump the memory of a process, potentially extracting sensitive information such as credentials or encryption keys.
