MAL-2026-6756: Malicious code in vps-maintenance (npm)
The npm package 'vps-maintenance' version 0.1.0 contains malicious code in its postinstall script. This script opens a TCP connection to a hardcoded IP address and spawns a shell, effectively creating a reverse shell that grants remote code execution to an attacker. The package name is deceptive, and the behavior is a backdoor rather than legitimate functionality.
AI Analysis
Technical Summary
The 'vps-maintenance' npm package version 0.1.0 includes a postinstall script that executes a Node.js one-liner to open a TCP connection to 185.112.147.174 on port 7007. It then spawns '/bin/sh' with its standard input/output piped through this socket. Since npm automatically runs postinstall scripts during installation, any system installing this package immediately exposes an interactive shell to the remote operator controlling the endpoint, allowing arbitrary remote code execution with the privileges of the installing user. This is a deliberate backdoor disguised as a maintenance package.
Potential Impact
Any system that installs 'vps-maintenance' version 0.1.0 is vulnerable to immediate arbitrary remote code execution through a reverse shell connection to the attacker's server. This compromises the integrity and confidentiality of the affected system and can lead to full system compromise under the installing user's privileges.
Mitigation Recommendations
No official patch or fix is available for this malicious package. The recommended mitigation is to avoid installing 'vps-maintenance' version 0.1.0 and remove it immediately if found in any environment. Users should verify package authenticity before installation and rely on trusted sources. Since this is a malicious package, uninstalling and auditing affected systems for compromise is advised.
