Sysinternals Tool Written to Disk
Detects Sysinternals executables written to disk on Windows endpoints, identified by the Sysinternals company name in the PE metadata of newly written EXE files. These are legitimate admin utilities, but attackers also copy them to hosts for discovery, process inspection and credential access. The rule shows tool presence only, not misuse, so it suits inventory and hunting. To triage, review the file path, hash, writing process and whether the user is an administrator.
