'RansomHub' Hacker Group Claims Responsibility for Attack on Christie's

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. In a post on the dark web, 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.
