Detects the execution of administrative or system-modifying tools (e.g., bash, sh, chroot, mount) or suspicious command lines involving root-level path manipulation or capability inspection (capsh) initiated by office applications, sandbox host processes, or specialized Excel engines. This behavior is indicative of a potential container breakout, privilege escalation, or post-exploitation activity originating from an initial access vector.
