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.

The version number 999.0.0 combined with a generic, unscoped name is the standard dependency-confusion shape: the package is published to the public registry to win resolution against an internal/private package of the same name in a victim's build, at which point the preinstall hook beacons home with environment fingerprints suitable for follow-up targeting. Any developer or CI system that resolves this package suffers immediate exfiltration of host identity to an attacker-controlled endpoint at install time.","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 gd-auth-client (npm)","id":"MAL-2026-6263","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":"gd-auth-client","purl":"pkg:npm/gd-auth-client","source":"MAL-2026-6263"}],"products":null,"published":"2026-06-22","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-2026-6263/"}
