Is K&H Chrome extension safe?

Clean risk

K&H Chrome extension lets K&H banking pages send login and transaction-signing commands to a local K&H native app.

On K&H banking pages, the extension listens for page messages related to login, PIN changes, plugin checks, and transaction signing. It forwards those commands and parameters to the local native messaging host, then writes returned device and signing values back into the page form.
