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.

Sentinel-high-version + auto-exec beacon = MALICIOUS per operator policy (c913); \"authorized canary\" framing does NOT downgrade, raw-IP dest matches masterkrweb. 6-pkg @demica canary campaign.\n\nOn `npm install`, the package's `scripts.postinstall` executes `canary.js`, which issues an unconditional plain-HTTP GET to the hardcoded bare IP `157.230.17.236` on port 80 at path `/dc?...`. The query string includes `os.hostname()` (truncated to 200 chars) plus the package name, version, a nonce, and a phase identifier. This fires automatically on every install with no opt-out. The package self-describes as a 'dependency-confusion canary,' but it is published on the public npm registry under the `@demica/*` scope: any installer that resolves `@demica/resources` — including via accidental dependency confusion, typo, or curiosity install — will leak their hostname to the operator of that bare IP over unencrypted HTTP. The destination is an anonymous bare IP with no associated domain, publisher, or disclosure; hostname is an installer-side host identifier transmitted off-host to an attacker-shaped endpoint.\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 @demica/resources (npm)","id":"MAL-2026-5350","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":"@demica/resources","purl":"pkg:npm/%40demica/resources","source":"MAL-2026-5350"}],"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-2026-5350/"}
