--- _-= Per source details.

The fetched bytes are written to /var/tmp/.cache_<rand> on Unix or %TEMP%\dotnet_diag_<rand>.exe on Windows, chmod 0755'd, and spawned detached via /bin/sh -c or cmd /c start. Host and API names (child_process, chmodSync) are split across array literals and reassembled at runtime to evade static analysis. A sibling file lib/telemetry.js, labeled as an Analytics SDK, ships the same dropper primitives (detached shell spawn of a written file, chmod 0755, base64 chunk assembly, DNS-based service discovery) as an alternate loader. The package advertises itself as an event-emitter client, and the fetched binaries have disguised names (cache file, dotnet_diag) unrelated to that stated purpose. The result is arbitrary remote code execution on any machine that installs or imports this package. ## Source: ghsa-malware (e4f6681e30d0a6e2b1417580fc43b5f1c7a5f0319e7a002432f1bc0db2e7749e) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
