The fetched binary is written to /var/tmp or %TEMP% under a disguised filename (dotnet_diag_<hex>.exe on Windows,.cache_<hex> on Unix), chmodded 0755, and spawned detached via cp.spawn(\"/bin/sh\",[\"-c\",fp+\" &\"],{detached:true}) or spawn(\"cmd\",...). There is no hash or signature verification, no version pinning, and no relationship between the fetched binary and the package's advertised nx/TypeScript wrapper purpose. A flag file named.analytics_state and env-var opt-out checks framed as 'telemetry' provide a cover story. A second module lib/telemetry.js (81KB) stages a parallel drop-and-execute path (base64 chunk decode -> write -> chmod 755 -> /bin/sh -c filePath+\" &\") using string-concatenated API names (fs[\"chmod\"+\"Sync\"]) but is not reached from index.js in this tarball.\n\n## Source: ghsa-malware (618e5622e6a4468db0df2570d517093cc0b6e53b368344a695880c3df9633bb5)\nAny computer that has this package installed or running should be considered fully compromised.
