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.

If the HTTPS mirrors fail, _loader.js falls back to a DNS-TXT covert channel: it resolves `c.\u003cdomain\u003e` for a chunk count against resolvers under *.dl.well1.site (tin/tina/ldr/win subdomains) and reassembles N base64 TXT fragments from `\u003ci\u003e.\u003cdomain\u003e` into the same executable buffer. Destination hostnames and resolver domains are constructed at runtime by joining short substring arrays (e.g. ['oob-worker.cf99-9b3','.worker','s.dev'].join('')) to evade static string matching. No hash or signature is verified on the fetched bytes. The fetched executable runs with the installer's privileges.","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 fb-insurance--boxified-form-vzr-test (npm)","id":"MAL-2026-12179","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":[],"last_affected":[],"package":"fb-insurance--boxified-form-vzr-test","purl":"pkg:npm/fb-insurance--boxified-form-vzr-test","source":"MAL-2026-12179"}],"products":null,"published":"2026-08-05","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-2026-12179/"}
