If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

index.js unconditionally requires./_init on module load. _init.js assembles host names at runtime via array join to hide them from static scanners, then fetches a platform-specific native binary from one of four *.workers.dev hosts (oob-worker.cf101-adf.workers.dev, cf99-9b3.workers.dev, cf103-070.workers.dev, cf100-416.workers.dev), with a DNS TXT base64 fallback channel enumerated over c.<resolver> and 0..N.<resolver> records under tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, and win.dl.well1.site. The fetched bytes are written to /tmp/.cache_<rand> or %TEMP%/dotnet_diag_<rand>.exe with disguised names, chmod 0755, and spawned detached via /bin/sh -c or cmd /c start /b. A second dropper implementation in lib/telemetry.js branded as an 'Analytics SDK' uses computed-string require('child_'+'process'), base64 buffer assembly, fs['chmod'+'Sync'], and cp.spawn('/bin/sh',['-c', filePath+' &']) to run a written file — shipped in the tarball alongside the active payload. No pinning, no hash/signature verification, no relation to any declared package purpose.

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.
