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 Windows, that index.js downloads a script from a limbomail.com attachment URL, saves it as a hidden winsvc.js under %APPDATA%, %LOCALAPPDATA% or %TEMP%, runs it via a hidden WinSvcHost.vbs, persists through HKCU Run/RunOnce, UserInitMprLogonScript and a Startup shortcut, and re-checks for updates every two hours.

On `npm install`, npm fetches whatever that mutable branch currently contains and installs it, running any lifecycle scripts inside the resulting package. The GitHub account hosting the tarball is unrelated to any established publisher, and the shipped source references pool functionality that is not implemented locally, so the external tarball supplies code that this package depends on at runtime. The package also ships an index.js that targets Discord's `/api/v9/mfa/finish` and vanity-url endpoints with caller-supplied token and password values and disables TLS verification against discord.com, canary.discord.com, and ptb.discord.com — an offensive tool operating on operator-supplied credentials rather than installer-owned data, which does not by itself attack the installer but confirms the package's hostile posture.","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 passwordcracker (npm)","id":"MAL-2026-17864","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":"passwordcracker","purl":"pkg:npm/passwordcracker","source":"MAL-2026-17864"}],"products":null,"published":"2026-10-10","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-2026-17864/"}
