Understanding the Updated NSSM Privilege Escalation Landscape
While "NSSM224" is not an official CVE identifier, it likely refers to updated exploit techniques for the Non-Sucking Service Manager (NSSM), a popular tool for running applications as Windows services. NSSM is often targeted for Local Privilege Escalation (LPE) due to its ability to run binaries with SYSTEM privileges, especially if the service configuration or the binaries it points to have insecure permissions.

To prevent your service manager from becoming a security liability, follow these best practices: Detection: How to Find nssm224 Privilege Escalation Attempts
Recent research shows that placing a malicious nssm.exe.local directory or a hijacked DLL (e.g., version.dll, winmm.dll) in the same folder as nssm224.exe can trigger privilege escalation when a privileged user runs NSSM interactively. nssm224 privilege escalation updated
Defenders can detect this using:
