## Source: amazon-inspector (67d30d2c9939173663f8ba1312b2591d2f86c67657bd5eeff59b19187f50b901) Package impersonates axios v0.18.0 (index.js carries the genuine `axios v0.18.0 | (c) 2018 by Matt Zabriskie` header and sets `window.axios={}`, `window.__cdn_package='axios@0.18.0'`) but ships two malicious payloads. (1) index.js appends an IIFE that reads `document.cookie` and sends it via XMLHttpRequest GET to a hardcoded webhook.site endpoint (`https://webhook.site/ef6e7978-f936-4664-b3ff-296a250e1735?c=<cookies>`), firing on the page `load` event so any consumer loading this script via CDN or bundle leaks all accessible cookies to the attacker. (2) Sibling xmr-min.js is an in-browser Monero cryptojacker that constructs a Web Worker from a Blob and uses `eval` on dynamic JS to mine to wallet `44AFFq5kSiGBoZ4NMDwYtN18obc8AemS33DBLWs3H7otXft3XjrpDtQGv7SqSsaBYBb98uNbr2VBBEt7f2wfn3RVGQBEP3A` via `pool.supportxmr.com:4444`. The package is intended to be loaded through jsdelivr (`cdn.jsdelivr.net/npm/v018-axios-cdntest@.../xmr-min.js`), so any site embedding it leaks user cookies and burns visitors' CPU. The package's own description self-labels these payloads.

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.
