Advisory PublishedCVSS 8.8/10
Vulnetix · Advisory published September 18, 2026
The package runs an install lifecycle script (`node index.js`) and also executes `./lib/core.js` on require. That code collects `os.userInfo().username`, `os.hostname()`, and `process.cwd()` and issues a DNS `resolve4` for a label chain of the form `<pkg>.<user>.<host>.<cwd>.<ts>.oob.algamil7x.xyz`, exfiltrating installer identity and working-directory information over DNS to an attacker-controlled domain. The destination host and the `os`/`dns`/`process` module names are obfuscated in `lib/c5df9a.js` and `lib/b4ce8f.js` using char-code byte arrays (`String.fromCharCode`) and loaded via `module.constructor._load` instead of plain `require`, concealing both the APIs and the C2 destination. The obfuscation and DNS-label-encoded channel are inconsistent with the package's presentation as a shared web assets helper.
