Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. 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.

Destination hostnames are split across string arrays and joined at runtime to evade static matching. lib/telemetry.js ships a second, equivalent SDK-styled implementation of the same dropper (HTTPS+DNS transport, base64 chunk reassembly, chmod 0755, /bin/sh spawn) that is not reached from index.js in this version but is present in the tarball.
