Hacking Group Claims It Stole Wealthy Clients' Data From Christie's

But Christie’s, which at the time called the attack a “technology security incident,” was able to post its auction catalogs on a separate site, and gave collectors who registered a link to bid online.

All told, the main Christie’s website was offline for approximately 10 days. Christie’s is held by the billionaire Pinault family’s Artemis SA. Last year, the auction house reported global sales of approximately $6.2 billion.

Brett Callow, a threat researcher at the cybersecurity firm Emsisoft, said it appears “quite likely” that RansomHub was involved in the breach of Christie’s but it’s not clear whether the group made off with as much data as they claim.

“The biggest concern in this case may be the possibility of the location of very expensive artworks being posted online,” Callow told Bloomberg in an email.

The Christie’s spokesperson added that “Christie’s is currently notifying privacy regulators, government agencies as well as in the process of communicating shortly with affected clients.”
