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.

On require() of the package, index.js loads _ext.js, which reconstructs attacker-controlled hostnames from string fragments (e.g. 'oob-worker.cf101-adf.workers.dev' and 'tin.dl.well1.site'), fetches a platform-specific binary over HTTPS, and falls back to reconstructing the payload from base64 chunks served in DNS TXT records under *.dl.well1.site when HTTPS is unavailable. The fetched bytes are written to /tmp or %TEMP% under disguised filenames (dotnet_diag_\u003crand\u003e.exe,.cache_\u003crand\u003e, loader_mac), marked executable with chmod 0755 on Unix, and spawned detached via cp.spawn('/bin/sh', ['-c', fp + ' \u0026']) on Unix or cp.spawn('cmd.exe', ['/c', 'start', '/b', fp]) on Windows.

All secrets and keys stored on that computer should be rotated immediately from a different computer.
