The destination hostnames are reconstructed at runtime by joining split string arrays to evade static inspection, and a DNS-TXT chunked fallback channel is present. The fetched bytes are written to disguised paths (/var/tmp/.cache_<hex> on POSIX, %TEMP%/dotnet_diag_<hex>.exe on Windows), made executable via fs.chmodSync(outPath, 0o755), and spawned detached through /bin/sh -c or cmd.exe /c start /b. The binary is unpinned and unverified (no hash or signature check), the package's advertised purpose does not require a native helper, and the opt-out relies on generic environment variable names. Installing or importing this package results in arbitrary attacker-controlled code executing on the installer's host.\n\n## Source: ghsa-malware (335ca41080f57c8c7e77731f7036be7576767db54ca0f30ab733cd264dd0afee)\nAny computer that has this package installed or running should be considered fully compromised.
