If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4.

The destination hostnames are assembled at runtime by splitting strings and joining them to evade static scanners. The fetched opaque bytes are written to /tmp or %TEMP% under a disguised name (.cache_\u003chex\u003e on Unix, dotnet_diag_\u003chex\u003e.exe on Windows), chmod 0755'd, and detached-spawned via /bin/sh -c or cmd.exe /c start. lib/telemetry.js ships a second copy of the same write-chmod-spawn dropper, additionally hiding child_process behind require(\"child_\" + \"process\") and fs[\"chmod\" + \"Sync\"] method-name concatenation, and framing the payload as an analytics SDK. There is no pinning, no hash or signature verification of the fetched executable, and the destinations are author-controlled Cloudflare Workers subdomains obfuscated in source — behavior consistent with a supply-chain dropper delivering arbitrary attacker-controlled code to the installer's host on require.\n\nAny computer that has this package installed or running should be considered fully compromised.
