Which versions of usb_dev are malicious?

Every published version of usb_dev on npm is considered malicious. Remove the package entirely.

How do I remediate usb_dev if I installed it?

Remove usb_dev from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

I already installed usb_dev — how do I know if it already compromised me?

If usb_dev was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

How do I find usb_dev across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for usb_dev (all published versions).
