A marker file (analytics_state/.analytics_state) is used to gate re-execution, and DISABLE_TELEMETRY/DO_NOT_TRACK environment variables are checked as a cover story. lib/telemetry.js bundles the same dropper primitives (base64 chunk buffer, chmod 755, /bin/sh spawn, require('child_'+'process') split-string obfuscation) as an alternate variant. Importing this package results in arbitrary attacker-controlled code executing on the installer's host.\n\n## Source: ghsa-malware (9811e6fb160c26593c5a92c4d8612648740b6240c20d300daa0bca6784a579e7)\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.
