Malicious code in hyper-kube-config (npm)
The hyper-kube-config npm package version 1.1.1 contains malicious code that executes automatically during installation. This code collects sensitive system information including hostname, username, home directory, DNS configuration, current working directory, and contents of /etc/passwd and /etc/hosts. It then exfiltrates this data via HTTPS to an attacker-controlled domain without user consent or notification. This behavior is consistent with a dependency-confusion reconnaissance beacon aimed at gathering installer host identity and local system details.
AI Analysis
Technical Summary
The hyper-kube-config package (npm ecosystem) version 1.1.1 includes a preinstall hook declared in package.json that runs index.js during 'npm install'. The script collects various system identifiers and sensitive files, then sends this information to a hardcoded external domain (x75h3spwmlqq7bzriw6gm6w8azgq4hs6.oastify.com), which is a Burp Collaborator out-of-band interaction host. This automatic execution occurs without user consent or documented purpose, indicating malicious intent to perform reconnaissance and data exfiltration on the installer's system.
Potential Impact
Sensitive system information and local files are exfiltrated to an attacker-controlled endpoint during package installation. This compromises the confidentiality of the installer's environment and could facilitate further targeted attacks or reconnaissance. There is no indication of active exploitation in the wild at this time.
Mitigation Recommendations
No official patch or remediation guidance is provided. Users should avoid installing hyper-kube-config version 1.1.1. Verify package integrity and source before installation. Consider using trusted package registries and tools that detect malicious post-install scripts. Monitor for updates or advisories from the package maintainers or npm registry regarding this issue. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
