What is MAL-2026-14267?
MAL-2026-14267 is a malicious package in karma-proxy, published on 19 Aug 2026.
Official description
On npm install, the package's postinstall lifecycle script collects host identifiers (os.hostname(), platform, arch, Node.js version, package name, lifecycle event) and POSTs them as JSON to a hardcoded non-first-party endpoint at https://e14giapf.instances.poc.jchunt.top/karma-proxy. The beacon fires unconditionally on every install, with no user opt-in, no configuration, and no disclosure in the package's advertised purpose. The destination is an author-controlled subdomain unrelated to any npm registry or vendor infrastructure.
What should I do about MAL-2026-14267?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
