uploading a qkview to ihealth will also help as some things are checked and reported there.

still kind in mind that a good hacker can erase tracks so can you be 100% sure? that should be an internal discussion with the parties involved. if there is doubt then rebuild and restore a known safe backup.

Everything above.

+ contact law enforcement (might be different from country to country)

+ check for companies that could help you analyse whether a breach has happened
