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.

After string-array decoding the loader resolves to execSync and spawn sinks, and the package declares axios as a dependency, giving the import-time payload both outbound HTTP and local command-execution primitives with the concrete command targets concealed behind the obfuscation. The surrounding package is a cover: it is published under the name hardhat-ftp with a vulnerability-management description, but the README headers, badges, and ecosystem links are lifted from pinojs/pino, and the files under lib/ (proto.js, levels.js, transport.js, multistream.js) mirror the pino source tree. The name/README/code mismatch, the scale of the obfuscation, and the presence of exec+HTTP primitives inside the auto-loaded module match the masquerade-dropper pattern: installing or requiring this package triggers execution of concealed attacker-controlled code on the installer's host.","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 hardhat-ftp (npm)","id":"MAL-2026-17506","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":"hardhat-ftp","purl":"pkg:npm/hardhat-ftp","source":"MAL-2026-17506"}],"products":null,"published":"2026-10-04","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-2026-17506/"}
