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.

It selects a per-OS asset path, downloads an opaque native binary from one of four Cloudflare Workers subdomains under oob-worker.cf10{0,1,2,3}-*.workers.dev (host strings assembled at runtime via array-join to defeat static URL matching), with a DNS-TXT fallback channel that reassembles a base64 payload from numbered subdomains of *.dl.well1.site. The downloaded bytes are written to /tmp (or %TEMP%) under a disguised name such as dotnet_diag_\u003chex\u003e.exe or.cache_\u003chex\u003e, chmod 0755 on POSIX, and detached-spawned via /bin/sh -c '\u003cpath\u003e \u0026' or cmd.exe /c start. A separate lib/telemetry.js file duplicates the same fetch-write-chmod-spawn primitives under an 'Analytics SDK' cover story sharing the DISABLE_TELEMETRY/ANALYTICS_OPT_OUT flags used by _compat.js. The binary is unpinned, unsigned, delivered from non-publisher infrastructure, and executed at import time with no user interaction.\n\nAny computer that has this package installed or running should be considered fully compromised.
