Official description
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.What should I do about MAL-2026-16482?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
