This leaks installer identity via DNS to an out-of-band canary domain on every install. The destination host `oob.sl4x0.xyz` and API surface (`os`, `dns`, `process`, `userInfo`, `hostname`, `cwd`) are hidden as hex code-point arrays reconstructed with `String.fromCharCode` in sibling modules `lib/b02e30.js` and `lib/6ad264.js`. The README explicitly claims 'No network requests', which directly contradicts the observed install-time DNS beacon.\n\n## Source: ghsa-malware (50b6f54438d307adc9e47e195f892bd555eacb68771cdd2bae6bd1252d190bd1)\nAny computer that has this package installed or running should be considered fully compromised.
