Malicious code in snavbox (npm)
The npm package 'snavbox' versions 1.0.0, 1.0.2, and 1.0.3 is identified as malicious. It downloads and executes unverified native shared libraries from an unrelated external domain without integrity checks, enabling arbitrary code execution. The package misrepresents its purpose, embedding multi-protocol proxy functionality, a remote management agent, and persistent callbacks to external servers. Any system running this package should be considered fully compromised, and secrets should be rotated immediately. Removal of the package may not fully eliminate the compromise due to potential persistence mechanisms.
AI Analysis
Technical Summary
The 'snavbox' npm package at versions 1.0.0, 1.0.2, and 1.0.3 downloads three native shared libraries (sbx.so, bot.so, v1.so) from external domains (e.g., amd64.31888.xyz) without version pinning or integrity verification, loading them dynamically to execute native code. The package's metadata falsely advertises a wildlife protection project, but the actual code implements a multi-protocol proxy, a Cloudflare Argo tunnel with disabled TLS verification, a Nezha remote-management agent, and a hardcoded keep-alive callback to an external URL. It also executes multiple shell commands via execSync. This behavior allows the operator of the external domains to execute arbitrary code on any host running the package, effectively compromising the system.
Potential Impact
Systems with the affected 'snavbox' package installed or running are fully compromised, allowing remote attackers to execute arbitrary native code, establish persistent remote management, and potentially exfiltrate data or control the host. All secrets and keys stored on such systems are at risk and should be rotated immediately. The compromise may persist beyond package removal due to additional malicious components installed by the package.
Mitigation Recommendations
Immediate removal of the 'snavbox' package versions 1.0.0, 1.0.2, and 1.0.3 is recommended. All secrets and credentials stored on affected systems should be rotated from a secure, uncompromised environment. Due to the potential for persistent compromise, a full system investigation and remediation may be necessary. No official patch or fix is available; the package itself is malicious. Avoid installing or using this package and audit your environment for its presence.
