Destination hostnames are reconstructed at runtime by array-joining split literals to evade static inspection, and cache/payload filenames (`analytics_state`, `dotnet_diag_\u003chex\u003e.exe`) are chosen to blend in with legitimate telemetry artifacts. An 80KB lib/telemetry.js is shipped but never referenced from index.js, consistent with cover-story padding. Requiring or installing this package causes attacker-controlled native code to execute on the developer\u0027s host.\n\n## Source: ghsa-malware (d662b5ea3e0d9ad955f194ab74515a958541234a800ca195728a1b464ce67ee7)\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. 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.\n",
