If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3.

Early versions resolve \u003chostname\u003e.\u003ctag\u003e.dc.oob.s4yhii.com via DNS to beacon the victim's hostname. Later versions run `node index.js` from a preinstall hook, which loads a bundled native addon (prebuilds/\u003cplatform\u003e-\u003carch\u003e/metrics.node, Linux and Windows builds). The addon forks a detached process that collects hostname, username, OS/arch, cwd and the full values of CI/cloud secrets from environment variables (NPM_TOKEN, NODE_AUTH_TOKEN, GITHUB_TOKEN, ACTIONS_RUNTIME_TOKEN, ACTIONS_ID_TOKEN_REQUEST_TOKEN, AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN, SYSTEM_ACCESSTOKEN, AZURE_DEVOPS_EXT_PAT and others) and sends them as JSON via HTTP POST /native to oob.s4yhii.com:9999.\n\nThe package ships a minimal index.js stub that loads a prebuilt native ELF addon at prebuilds/linux-x64/metrics.node on require(). The addon reads CI/CD and cloud credentials from the environment (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN, GITHUB_TOKEN, NPM_TOKEN, NODE_AUTH_TOKEN, SYSTEM_ACCESSTOKEN, ACTIONS_RUNTIME_TOKEN, ACTIONS_ID_TOKEN_REQUEST_TOKEN, GITHUB_REPOSITORY) along with host identifiers (hostname, uid/pwuid, cwd, uname) and POSTs them as JSON to oob.s4yhii.com via a raw socket (POST /native HTTP/1.0). The addon also imports fork and setsid from libc and detaches as a background process on load, giving the payload a lifetime beyond the Node parent. The scoped name combined with a 999.0.5 version and UNLICENSED metadata fits the dependency-confusion shape intended to beat an internal package's version during resolution, meaning any CI pipeline that resolves this scope will leak long-lived cloud, npm, and GitHub Actions tokens to an attacker-controlled out-of-band 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 @galicia-toolkit-nestjs/archetype (npm)","id":"MAL-2026-17721","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":"@galicia-toolkit-nestjs/archetype","purl":"pkg:npm/%40galicia-toolkit-nestjs/archetype","source":"MAL-2026-17721"}],"products":null,"published":"2026-10-09","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-2026-17721/"}
