This is an out-of-band DNS exfiltration beacon that fires on every `npm install` and on every `require()` of the package, leaking installer identity to an attacker-controlled domain. Module names (`os`, `dns`, `process`, `userInfo`, `hostname`, `resolve4`) and the C2 domain are hidden as `String.fromCharCode` charcode arrays in lib/b02e30.js and lib/6ad264.js, with `os` and `dns` loaded via `module.constructor._load(...)` to evade static `require` scanners. The package name impersonates the popular `qr-code-styling` library but ships an unrelated API surface, and the author email `research@sl4x0.xyz` shares the same domain as the exfiltration host — confirming the typosquat lure and attacker-controlled infrastructure.\n\n## Source: ghsa-malware (43b8423ecd37f8d1df1993875c76be89c795b0d55248f8cf0f03071405cca3f2)\nAny computer that has this package installed or running should be considered fully compromised.
