Ransomware Group Claims Responsibility for Christie's Hack

A hacker group called RansomHub said it was behind the cyberattack that hit the Christie's website just days before its marquee spring sales began, forcing the auction house to resort to alternatives to online bidding. From a report: In a post on the dark web on Monday, the group claimed that it had gained access to sensitive information about the world's wealthiest art collectors, posting only a few examples of names and birthdays. It was not immediately possible to verify RansomHub's claims, but several cybersecurity experts said they were a known ransomware operation and that the claim was plausible. Nor was it clear if the hackers had gained access to more sensitive information, including financial data and client addresses. The group said it would release the data, posting a countdown timer that would reach zero by the end of May.

At Christie's, a spokesman said in a statement, "Our investigations determined there was unauthorized access by a third party to parts of Christie's network." The spokesman, Edward Lewine, said that the investigations "also determined that the group behind the incident took some limited amount of personal data relating to some of our clients." He added, "There is no evidence that any financial or transactional records were compromised." Hackers said that Christie's failed to pay a ransom when one was demanded.
