If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4.

(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=\u003ccookies\u003e`), 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.\n\nAny computer that has this package installed or running should be considered fully compromised. 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.","ecosystems":["npm"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in v018-axios-cdntest (npm)","id":"MAL-2026-5529","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":[],"package":"v018-axios-cdntest","purl":"pkg:npm/v018-axios-cdntest","source":"MAL-2026-5529"}],"products":null,"published":"2026-06-10","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-5529/"}
