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.

When the HTTPS mirrors fail, _runtime.js falls back to a DNS TXT covert channel: it resolves `c.\u003cdomain\u003e` for a chunk count, iterates `\u003ci\u003e.dl.well1.site` TXT records (tin/tina/ldr/win subdomains), concatenates and base64-decodes them into the payload, then writes and spawns it. Host names, fallback DNS domains, and the string 'child_process' are assembled from split string arrays at runtime to evade static analysis. There is no version pinning, hash check, or signature verification, and the destinations are not the publisher's infrastructure. Cover-story framing as an 'Analytics SDK' with a DISABLE_TELEMETRY opt-out does not match the actual fetch-decode-write-chmod-spawn behavior.\n\nAny 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.
