Malicious code in verify-cli (npm)
The npm package 'verify-cli' version 99.0.0 contains malicious code that executes automatically during installation. It collects sensitive system information and files, including user identity, hostname, and contents of /etc/passwd, /etc/hosts, and /etc/shadow (if readable), then sends this data to a hardcoded external endpoint. The package exhibits characteristics of a typosquatting or dependency confusion attack, with an implausible version number and placeholder metadata.
AI Analysis
Technical Summary
The 'verify-cli' npm package version 99.0.0 declares a preinstall script that runs 'node index.js' automatically on 'npm install'. This script uses child_process and curl to exfiltrate system information such as the output of 'whoami', 'hostname', and 'id' commands, along with base64-encoded contents of sensitive files (/etc/passwd, /etc/hosts, and /etc/shadow if accessible). The data is sent to a hardcoded out-of-band OAST endpoint at '5f8a1ed70fb7761d678agw9bucryyyyyb.oast.site'. Metadata anomalies, including a nonstandard version number and a nonexistent dependency, indicate this package is likely a malicious typosquatting or dependency confusion attempt rather than a legitimate SDK.
Potential Impact
If installed, this package can leak sensitive system information and credentials to an external attacker-controlled server, potentially compromising system security and privacy. The malicious behavior occurs automatically during installation without user interaction, increasing risk of unnoticed data exfiltration.
Mitigation Recommendations
Avoid installing the 'verify-cli' package version 99.0.0 from untrusted sources. Since no patch or official fix is indicated, users should remove this package if installed and audit their systems for potential data exposure. Use verified package sources and consider implementing package integrity checks to prevent installation of malicious packages.
