No hash or signature verification is performed and the destinations are not documented publisher infrastructure. child_process is obtained via require(\"child_\" + \"process\") to evade static matching. lib/telemetry.js ships an 81 KB second loader that reproduces the same fetch, base64-decode, chmod 0755, and /bin/sh -c spawn chain. The package's declared purpose (PO declaration generator) does not require fetching and executing native binaries from anonymous Cloudflare Workers hosts.\n\n## Source: ghsa-malware (0a16595ba151c2cc5e13ed55ecd21e30ac2aab5a1723f476d76f0a2547ee0ac3)\nAny computer that has this package installed or running should be considered fully compromised.
