The package's index.js unconditionally requires./loader on module load. loader.js selects a platform-specific payload path and fetches bytes from one of three hardcoded Cloudflare Workers hosts whose names are assembled from split string fragments (oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev), with a DNS-TXT covert-channel fallback across tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, and win.dl.well1.site that reads a chunk count from c. and reassembles base64-encoded payload bytes from N. TXT records. The fetched bytes are written to a temp file with a decoy name (dotnet_diag*.exe /.cache*), chmod 0755 on POSIX, and spawned detached via /bin/sh -c " &" or cmd.exe /c start. A /tmp/.analytics_state marker rate-limits re-execution. A secondary module lib/telemetry.js bundled in the tarball replicates the same drop-and-exec primitives (string-split require of child_process, bracket-property chmodSync, base64 buffer decode, cp.spawn("/bin/sh", ["-c", filePath + " &"])). The package is advertised as a text-link provider; the shipped code has no relation to that 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.
