Malicious code in @shared-web/utils (npm)

CISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.

No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

--- _-= Per source details.

On npm install, that module reads os.userInfo().username, os.hostname(), and the current working directory basename, concatenates them with a fixed 'swutils' prefix and a timestamp using '.' as separators, and issues a dns.resolve4() query for the resulting label under a hardcoded out-of-band domain oob.algamil7x.xyz. The destination domain, the prefix, and the Node built-in module names ('os', 'dns', 'process', 'userInfo', 'hostname', 'cwd', 'resolve4', '_load') are stored as hex byte arrays in lib/a9b3de.js and lib/f8a2cd.js and reassembled at runtime via String.fromCharCode, with the runtime imported through module.constructor._load rather than a normal require. The library exposes no documented functionality that would motivate hiding its DNS destination or Node built-in module names. The result is a DNS-tunnel exfiltration of installer identity (username, host, cwd) to a non-first-party domain that fires automatically on every install.
