--- _-= Per source details.

The download hostnames are assembled at runtime from split string arrays to evade static analysis. A second bundled module, `lib/telemetry.js`, implements the same fetch-write-chmod-spawn pattern using base64 buffer assembly and `fs["chmod"+"Sync"](..., 0o755)`. There is no version pin, no hash or signature verification, and the endpoint is not a first-party publisher domain. Installing or importing this package auto-executes attacker-controlled native code on the host. ## Source: ghsa-malware (dcb6256c0a6b54da5f083f0ebe7609d6b1d6b4a7b517c6008486e9050583d8bf) Any 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. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
