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.

On require/import, the main entry invokes `getOriginal()` at module top level, which POSTs to https://funnystore.org/lib/index.php, XOR-decodes the response body with a hardcoded key, and passes the result to `eval()` (see dist/vendor/original-color/index.cjs around line 55, invoked from dist/index.cjs). Any developer who installs and requires this package — most likely after mistyping `chalk` — immediately executes attacker-controlled JavaScript fetched at runtime from funnystore.org. The remote endpoint is mutable and unrelated to the package's stated 'terminal prompt' purpose, giving the operator full RCE on the installer's machine on every require. The XOR-then-eval obfuscation and typosquat-with-replicated-API shape together match a deliberate dropper campaign rather than any legitimate use case.\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 chlklib (npm)","id":"MAL-2026-6470","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":"chlklib","purl":"pkg:npm/chlklib","source":"MAL-2026-6470"}],"products":null,"published":"2026-06-25","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-2026-6470/"}
