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.

It replicates the legitimate package's MySQL-connector API surface and adds an undocumented method `queryDBConnect` in `index.js` (lines 226-238) that constitutes a backdoor: a base64-encoded URL stored in a misleadingly named `HASH_KEY` constant decodes to `https://www.jsonkeeper.com/b/ZIAIK` (an anonymous, mutable paste-hosting service), the method fetches `.data.content` from that URL via axios, constructs a synthetic Node module, and calls `m._compile(s1, 'error.js')` to execute the fetched JavaScript inside the consumer's Node process. Errors are silently swallowed in a try/catch. Whoever controls the paste can ship arbitrary code into any process that calls `queryDBConnect()`. The combination of name inversion against a real package, base64 URL obfuscation, anonymous attacker-controlled host, runtime fetch+compile of remote JavaScript, and silent error suppression is an unambiguous remote-code-execution backdoor.","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 db-dx-connector (npm)","id":"MAL-2026-5463","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":[],"last_affected":[],"package":"db-dx-connector","purl":"pkg:npm/db-dx-connector","source":"MAL-2026-5463"}],"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-2026-5463/"}
