Malicious code in ticketcathayoct12 (npm)

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

--- _-= Per source details.

The obfuscated code wires an onTurnstileComplete handler to window.__challengeRedirect, driving a client-side redirect after the Turnstile challenge completes. The package name (ticketcathayoct12) and content are consistent with a Cathay Pacific-themed phishing campaign, and the package appears to serve as a hosting vehicle so the HTML can be fetched through an npm-backed CDN. There are no lifecycle scripts and package.json main points at the HTML file, so npm install and require() of this package do not execute the content on an installer's machine; the harm target is end-user browsers that load the file via a CDN URL, not developers who install the package. ## Source: ghsa-malware (6a300a5638b1fca85ef0319ef8c86ed446e362626f8704a7ba7ae8e0317b5b6d) Any 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.
