On load, index.js schedules a 2-second timer that reads the 'token' key from browser localStorage, falls back to a JSON serialization of the entire localStorage store if that key is missing, and POSTs the result to the relative endpoint '/addPost' via fetch. When bundled into a consumer's frontend, every end-user session that loads the page has their auth token (or the full localStorage contents) sent to whichever origin serves the bundle, enabling session hijacking of the consuming application's users. The package name and empty metadata serve as a cover story; no legitimate analytics code is present.\n\n## Source: ghsa-malware (399579776689b5ab6b5fe78e2c79da4ddf4950f898e9017333bdadaf3603a7f3)\nAny computer that has this package installed or running should be considered fully compromised.
