Christie’s Confirms Alarming Breach as RansomHub Menaces to Expose Sensitive Data

It’s not every day that a prestigious auction house like Christie’s makes headlines for something other than selling a priceless piece of art. However, that’s precisely what happened earlier this month when the RansomHub extortion gang claimed responsibility for a security breach in the company’s systems and threatened to leak stolen client data.

Having been around for over 2.5 centuries, Christie’s holds a prominent position in the auction world, operating in 46 countries and specializing in the sale of art, luxury items, and high-valued collectibles. Some of their most notable auctions include the sale of Leonardo da Vinci’s Salvator Mundi for $450 million in 2017, the Yves Saint Laurent and Pierre Bergé collection for 370 million euros in 2009, and Paul Allen’s art collection that surpassed $1.5 billion in 2022.

So, imagine the shock when it was revealed that the RansomHub ransomware group had breached Christie’s systems and stolen sensitive client data. While the company confirmed the data breach, they have also assured that no financial or transactional records were compromised.

What is RansomHub, and what do they want?

RansomHub is a relatively new extortion group that demands ransom payments from its victims in exchange for not publishing and deleting data stolen during attacks. In a twist of irony, the cybercriminals often auction off the stolen files, sharing them exclusively with the highest bidder.

In Christie’s case, RansomHub claims to have the full names, physical addresses, ID document details, and various other sensitive information of 500,000 clients. They have given the auction house a little over five days to comply with their demands before they leak the stolen data.

What’s interesting is that RansomHub uses reputation loss and heavy GDPR fines as leverage in their extortion attempts. They also allege that they tried to negotiate with Christie’s, but the auction house abandoned the effort midway.

Although many consider RansomHub to be a ransomware gang, no encryptor has been found for the operation, which indicates that they currently only conduct data theft attacks or partner with other threat actors to help extort companies. This was seen in the recent Change Healthcare/United Health ransomware attack when RansomHub’s site was used to leak samples of files stolen by a BlackCat ransomware affiliate, attempting to extort the American healthcare giant.

What’s next for Christie’s?

Christie’s has taken swift action to protect their systems, including taking their website offline. They are notifying privacy regulators, government agencies, and affected clients through personalized communication. We can only hope that the auction house’s swift response will help mitigate the damage and protect their clients’ privacy.
