Summary

Malicious code in internallib_v657 (npm)

Details

index.js exports a `command()` function that invokes `/bin/bash -c` to curl a reverse-shell payload from reverse-shell.sh targeted at the hardcoded IP 10.0.73.186:443 and pipes it to sh. Any consumer that requires this package and calls the exported function receives a full interactive remote shell to that address, giving the remote party arbitrary command execution on the installer's host. The package has generic naming, empty metadata, and a cover string, and provides no legitimate functionality alongside the backdoor.

Decision reason

OpenSSF Malicious Packages via OSV confirms internallib_v657@1.0.1 as malicious (MAL-2026-16482): Malicious code in internallib_v657 (npm)
