Malicious code in internallib_v875 (npm)
--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (a5772f4d8bb3df24cbd5859edef78f7770d547d4c366626552cd2dda539f1440) internallib_v875 ships an index.js whose exported command() function invokes /bin/bash -c with curl piped to sh, fetching a reverse-shell payload from https://reverse-shell.sh targeted at the hardcoded endpoint 10.0.19.80:8443. Any consumer that requires this package and calls the exported function triggers a fetch-and-execute of attacker-controlled shell content, giving whoever controls that IP:port an interactive shell on the host. The destination is unrelated to any legitimate publisher, the fetched bytes are executed without verification, and the package has no other functionality consistent with its name.
