: If the path to the executable NSSM manages contains spaces and is not enclosed in quotes (e.g., C:\Program Files\App Name\nssm.exe ), an attacker can place a malicious file (e.g., C:\Program.exe ) to be executed by the system during reboot .

Penetration testers have refined the nssm224 attack chain. Here is the modern methodology: Here is the modern methodology: In the ever-evolving

In the ever-evolving landscape of Windows privilege escalation techniques, few identifiers have maintained the staying power of . Originally documented as a proof-of-concept for abusing the Non-Sucking Service Manager (NSSM) utility, this attack vector has recently resurfaced in penetration testing reports and red team operations. Security researchers have released updated findings on how attackers leverage NSSM version 2.24 (and adjacent builds) to bypass standard security boundaries.

Executive Summary: NSSM Local Privilege Escalation (LPE) NSSM (Non-Sucking Service Manager) version

The Non-Sucking Service Manager ( nssm.exe ) is a legitimate, open-source utility designed to run any executable as a Windows service. Unlike sc.exe or PowerShell’s New-Service , NSSM handles service failure recovery, environment variables, and graceful shutdowns. It is widely deployed by system administrators to convert batch scripts, Node.js apps, or Python daemons into persistent services.
