What is MAL-2026-17635?
MAL-2026-17635 is a malicious package in internallib_v875, published on 6 Oct 2026.
Official description
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.
What should I do about MAL-2026-17635?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
