internallib_v275npm

index.js exports a command function that invokes /bin/bash -c to curl a reverse-shell payload from reverse-shell.sh targeting the hardcoded host 10.0.49.106:443 and pipes the response to sh, yielding interactive remote shell access on the installer host whenever the exported API is called. The fetch-and-execute path has no pinning, no hash verification, and runs over an unauthenticated network retrieval. package.json also declares a self-referential dependency on internallib_v275@^1.0.0, a dependency-confusion shape consistent with a package targeting an internal registry namespace so that resolution against the public registry pulls this backdoor into internal builds.

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.
