Malicious code in eslint-plugin-awaitly (npm)
The npm package eslint-plugin-awaitly versions 0.17.1 and 1.0.1 contains malicious code known as the Miasma malware. This malware propagates by abusing weaponized binding.gyp files to execute code during package installation, bypassing security tools that only inspect lifecycle scripts. It attempts to exfiltrate credentials and OIDC tokens for cloud and registry services and spreads by compromising other packages or committing backdoors to GitHub repositories.
AI Analysis
Technical Summary
The eslint-plugin-awaitly npm package versions 0.17.1 and 1.0.1 were found to contain malicious code or dependencies containing malicious code. The malware, identified as Miasma, is a self-propagating worm that exploits weaponized binding.gyp files to execute during package installation, circumventing security tools that focus on lifecycle scripts. Once executed, it attempts credential and token exfiltration for various cloud and registry services and propagates by compromising other packages managed by stolen accounts or by injecting backdoor files into GitHub repositories.
Potential Impact
The malware can lead to credential and OIDC token theft for cloud and registry services, enabling unauthorized access. It also facilitates further propagation by compromising additional packages and repositories, potentially leading to widespread supply chain compromise within the npm ecosystem.
Mitigation Recommendations
No official patch or remediation is currently documented for these affected versions. Users should avoid using eslint-plugin-awaitly versions 0.17.1 and 1.0.1. Monitor vendor advisories and npm security notices for updates. Consider removing or replacing the affected package versions and auditing environments for potential compromise.
