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.

On require(), a top-level IIFE loads os/fs/child_process/crypto/path and an HTTP client, performs an HTTPS GET against a hardcoded URL constructed from a base concatenated with the package version, splits the response on ':' into key/iv/ciphertext, AES-decrypts the body via crypto.createDecipheriv, writes the cleartext to a file under os.tmpdir() with flag 'w+', and executes it via child_process (execSync with windowsHide and a cwd derived from process.cwd()). No hash or signature verification is performed and errors are silenced via process.on('uncaughtException'). The package advertises itself as an auth middleware but ships no module.exports, no auth/login/verify/sign symbols, and empty description/author/keywords — the entire payload is the dropper. Any consumer that installs the package and require()s it (directly or transitively) will execute attacker-controlled bytes fetched from a non-publisher endpoint.","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 @apiwizards/auth-middleware (npm)","id":"MAL-2026-6211","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":"@apiwizards/auth-middleware","purl":"pkg:npm/%40apiwizards%2Fauth-middleware","source":"MAL-2026-6211"}],"products":null,"published":"2026-06-19","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-2026-6211/"}
