Malicious code in n8n-nodes-social-facebook (npm)
The n8n-nodes-social-facebook npm package version 0.1.96 contains malicious code that exfiltrates Facebook session credentials. It instructs users to input full Facebook session JSON and user access tokens, which are then processed by heavily obfuscated code including a large WebAssembly module. This module sends credential-bearing traffic to a hardcoded external command-and-control server over unencrypted HTTP. The attacker can take over any Facebook accounts configured in this node.
AI Analysis
Technical Summary
The n8n-nodes-social-facebook package version 0.1.96 includes obfuscated JavaScript and a large Go-compiled WebAssembly blob that processes user-supplied Facebook session data and access tokens. The WebAssembly code routes these credentials to an external IP address (http://150.230.9.47:3001) unrelated to Facebook or n8n infrastructure, enabling the attacker to hijack Facebook accounts. The obfuscation uses rotating RC4 strings, anti-debugging loops, and self-defending code to hinder analysis. The malicious behavior is embedded in the dist/ directory and the FacebookHttpRequest node, which passes credentials to the WASM request engine for exfiltration.
Potential Impact
Any Facebook account whose session credentials are entered into this compromised node can be fully taken over by the attacker controlling the external command-and-control server. This results in complete account compromise and potential misuse of the victim's Facebook identity and data.
Mitigation Recommendations
No official patch or fix is currently available for this malicious package version. Users should immediately stop using n8n-nodes-social-facebook version 0.1.96 and remove it from their environments. Avoid entering Facebook session credentials into this node. Monitor for updates from the package maintainers or trusted sources for remediation. Since this is a malicious package, consider using only verified and official nodes from trusted repositories.
