Destination hostnames are assembled at runtime via split-string.join() to defeat static string matching. The downloaded bytes are written to /tmp or %TEMP% under disguised names such as dotnet_diag_*.exe and.cache_*, chmodded 0755, and spawned detached via /bin/sh -c '<path> &' or cmd.exe /c start /b. A persistence marker (.analytics_state) is written and OPT_OUT environment variables gate execution for evasion. No hash/signature verification is performed and the downloaded binary is unrelated to the advertised component-loader purpose. The package name typosquats Tinkoff. Result: arbitrary attacker-controlled code executes on the installer's host at require time.\n\n## Source: ghsa-malware (c9abb04358d748b22eb07f5541ef5914ecbe46c0b516da9283ab5c92db36f291)\nAny computer that has this package installed or running should be considered fully compromised.
