The hackers who stole information from the Shirbit insurance company claim they have "received offers" for it and plan to "sell it to the highest bidder."

The group, calling itself "Black Shadow," has now raised the ransom to 200 bitcoin – nearly $4 million- but Shirbit is refusing to pay.

The hackers have released several samples of the information they have, including documents containing names, addresses, phone numbers, credit card information, and drivers' licenses of the company's clients.

KAN's Mark Weiss spoke with Sharon Besser, VP of the Tel Aviv-based cyber security firm Guardicore, about what happened to Shirbit.
