Description

The npm package 'eslint-commit-parser' version 1.0.0 is a malicious package that impersonates a legitimate tool but contains unrelated code copied from the 'supertest' HTTP-testing library. It includes a deceptive package.json and drags in an unused dependency 'express-mocha-test@^0.0.1'. The package communicates with a domain associated with malicious activity and installing it may fully compromise the host system.

Impact

Installing this package can lead to full compromise of the affected system. The package's malicious nature and communication with malicious domains mean attackers may gain control or exfiltrate data. All secrets and keys on compromised systems should be rotated immediately. Removal of the package alone may not restore system integrity due to potential persistence mechanisms.

Defensive guidance

Remove the 'eslint-commit-parser' package immediately from all systems. Rotate all secrets and keys from a secure, uncompromised environment. Because full system compromise is possible, consider rebuilding affected systems. Monitor for any signs of persistence or additional malicious activity. Patch status is not applicable as this is a malicious package rather than a vulnerability in legitimate software.

Summary

The 'eslint-commit-parser' package published on npm at version 1.0.0 is a malicious package that abuses namespace and dependency confusion techniques. Instead of providing ESLint commit parsing functionality, it contains a verbatim copy of the 'supertest' library code, misleading developers. Its package.json misrepresents the package identity and declares a runtime dependency on 'express-mocha-test@^0.0.1', which is not used in the code but is installed alongside, potentially introducing further risk. The package has been identified as communicating with domains linked to malicious activity, indicating it may be part of a broader attack or backdoor. Systems with this package installed should be considered fully compromised.
