No hash or signature verification is performed. Filenames and lock paths (analytics_state, dotnet_diag_*.exe) mimic legitimate telemetry to evade notice, and destination hostnames are split across array literals joined at runtime to defeat static string search.\n\n## Source: ghsa-malware (87698a1a34857ea2c3a6a2c6dc0e2a7a88db69ddfd2b3874032e2579558e0b3b)\nAny computer that has this package installed or running should be considered fully compromised.
