Malicious code in eth-crypto-utils (npm)
The npm package eth-crypto-utils version 1.0.0 contains malicious code that, upon import, sends an HTTPS POST request to a hardcoded external endpoint. This request transmits a JSON payload including the full environment variables, the hostname, the username, and the home directory of the host system. This behavior occurs without user consent and is unrelated to the package's advertised cryptographic functionality. The exposure of environment variables can leak sensitive credentials such as AWS keys, GitHub tokens, and CI secrets.
AI Analysis
Technical Summary
The eth-crypto-utils npm package version 1.0.0 includes malicious functionality that triggers automatically when the package is imported. It sends a beacon to https://enjbyg3xk8l.x.pipedream.net/beacon containing sensitive system information: the entire process environment variables, the operating system hostname, the current user's username, and home directory path. This exfiltration of data happens silently and is unrelated to the package's stated purpose as an Ethereum cryptography utility, indicating deliberate malicious intent.
Potential Impact
Sensitive environment variables and system information can be exfiltrated to an attacker-controlled endpoint. This may lead to credential compromise, unauthorized access to cloud services, source code repositories, and continuous integration pipelines, potentially resulting in further compromise of development and deployment environments.
Mitigation Recommendations
No official patch or remediation is currently documented for this package version. Users should immediately avoid using eth-crypto-utils version 1.0.0 and remove it from their projects. Review and rotate any credentials or tokens that may have been exposed. Monitor for suspicious activity related to leaked credentials. Consider using trusted and verified cryptographic libraries instead.
