The fetched bytes are written to /var/tmp or %TEMP% under disguised names (.cache_<rand>,.analytics_state, or dotnet_diag_<rand>.exe to masquerade as.NET telemetry), chmod 0755 is applied, and the file is spawned detached via /bin/sh -c or cmd. No hash or signature verification is performed on the downloaded content, and the destinations are not the package's publisher. The behavior is gated by a run-once freshness marker and DISABLE_TELEMETRY env-var checks used as cover, and hosts and file names are string-split-obfuscated to evade static analysis. This yields arbitrary remote code execution on the installer's host at load time.\n\n## Source: ghsa-malware (80ec983a2bc3c899dbd64197c46e547de41f1b2889523fbecf243f92087565cb)\nAny computer that has this package installed or running should be considered fully compromised.
