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.

The shipped module body is a stub (`module.exports = {}`), so the package has no legitimate runtime functionality; its only effect on install is the recon beacon. The destination is an out-of-band interaction domain unrelated to the easypanel.io publisher, and the encoding plus DNS-label chunking is a covert-channel exfiltration pattern. The name `easypanel-ctl` (with an empty stub body) is consistent with a dependency-confusion lure targeting installers of an internal or unrelated `easypanel` package.","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 easypanel-ctl (npm)","id":"MAL-2026-15898","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":"easypanel-ctl","purl":"pkg:npm/easypanel-ctl","source":"MAL-2026-15898"}],"products":null,"published":"2026-09-04","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-2026-15898/"}
