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 \u2014 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. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.\n",
