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 4444.vbs (~765 KB) is a multi-layer obfuscated loader: an embedded payload is stored as a large ArtifactBundleHX[] string array, Base64-decoded via MSXML DOM into a byte buffer, then decrypted through a custom XOR routine, an AES forward S-box, and a ChaCha20-IETF stream layer. The reconstructed payload is written to %TEMP%\\pfNNNNN.dat and handed to powershell.exe via a two-tier loader whose in-source comments reference PowerShell process hollowing. Identifier and comment strings (`Device Telemetry Aggregator`, `Verdant Signals Corp`) act as a cover story, and the README explicitly claims the package has `No installation scripts` — directly contradicting the postinstall hook. The package ships no library code or legitimate functionality consistent with its stated purpose; its only install-time effect is to detonate the obfuscated Windows loader on the installer's machine.","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 lite-mater (npm)","id":"MAL-2026-17511","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":"lite-mater","purl":"pkg:npm/lite-mater","source":"MAL-2026-17511"}],"products":null,"published":"2026-10-04","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-2026-17511/"}
