If a service using NSSM is configured with an unquoted path containing spaces (e.g., C:\Program Files\App\nssm.exe ), an attacker can place a malicious executable at C:\Program.exe . Windows will attempt to execute Program.exe first when starting the service. Persistence and Malware:
Because NSSM is not a native Windows binary (unlike sc.exe ), it often bypasses application whitelisting rules that only check %SystemRoot%\System32 .
In the flickering fluorescent hum of Level 4, Elias stared at the string of characters that shouldn't exist: nssm-2.24 .
Move to the latest pre-release builds (e.g., 2.25) available on the NSSM Download Page , which fix many of the 2.24-specific bugs.
: To mitigate these risks, ensure all service paths in the registry are enclosed in double quotes and consider upgrading to the 2.25 pre-release or newer, which addresses several 2.24-specific bugs. NSSM - the Non-Sucking Service Manager Odoo 12.0.20190101 - 'nssm.exe' Unquoted Service Path
The Non-Sucking Service Manager, better known as NSSM, is a lightweight open-source utility for Windows that can run any executable, script, or command as a Windows service, ensuring applications remain active and restart automatically after crashes or reboots. First released in 2003 as an alternative to Microsoft's problematic srvany.exe , NSSM has become a staple for system administrators—and, increasingly, for malicious actors.
Despite its utility, the official NSSM project has seen little activity in recent years. Many official repositories (such as the one once maintained by Perforce) are now archived, and development appears to have stalled. This lack of ongoing maintenance is one of the key factors that makes older versions like 2.24 potentially risky in modern security environments.
: A common misconfiguration in Windows where the path to the executable contains spaces and is not enclosed in quotes (e.g., C:\Program Files\App\nssm.exe ). Attackers can place a malicious executable (like C:\Program.exe ) to intercept the service launch and gain elevated access.
