Embedded JavaScript reconstructs a fragmented path from a `_paths` array (`[\"/gh/\", \"s0n-1m-\", \"cr1n3/\", \"sc13nc3/\", \"assets/\", \"index.html\"]`) joined at runtime to form `/gh/s0n-1m-cr1n3/sc13nc3/assets/index.html`, prefixes a jsDelivr mirror host, fetches the URL, and writes the response body into a new browser tab via `document.write`, which parses and executes it as HTML/JS. A `setTimeout` fires the fetch automatically 500 ms after page load, and a hidden `class code` modal (m1..m5) triggers the same fetch on demand. Because the jsDelivr path targets a personal GitHub repository (`s0n-1m-cr1n3/sc13nc3`) pinned to no commit, the operator can swap the delivered payload at any time. The split-string obfuscation of the destination and the author-labeled decoy UI show intent to conceal the delivery channel behind a Google Classroom facade.\n\n## Source: ghsa-malware (623532fe0234f0604f33f448e7b994bb3817bc08b2e9c91d4739f337763013f9)\nAny computer that has this package installed or running should be considered fully compromised.
