The package's index.js unconditionally requires a vendor.js script that initiates a bootstrap routine fetching a platform-specific binary over HTTPS from three Cloudflare Workers hosts. The hostnames are constructed dynamically, and a DNS TXT fallback discovery mechanism is used. The fetched binary is saved to temporary directories with disguised filenames and executed with permissions set to 0755, using shell commands. The package also uses obfuscated code to load child_process and change file permissions to evade static detection. The payload and its delivery mechanism are unrelated to the package's stated functionality, indicating malicious intent. The package version affected is 20.6.6.

Any system with this package installed or running is considered fully compromised, as the malicious code downloads and executes arbitrary binaries without integrity checks. This can lead to complete system takeover by an attacker. All secrets and keys stored on the compromised system are at risk and should be rotated immediately from a secure environment. Removing the package alone may not eliminate all malicious components due to the potential for persistent backdoors or additional malware installed by the payload.

Remove the malicious package immediately from all affected systems. Rotate all secrets, keys, and credentials that were stored or accessible on the compromised systems from a different, trusted machine. Because the package executes arbitrary binaries without verification, assume full system compromise and consider rebuilding affected systems if possible. Monitor for any signs of persistent malware or backdoors. There is no known patch or official fix for this package; avoidance and removal are the only mitigations.
