Auction house Christie's has confirmed suffering a data breach after a ransomware group on Monday threatened to leak information stolen from the company.
The cyberattack was launched just as the auction house was attempting to sell high-value items worth an estimated $840 million.
While the incident prevented potential buyers from viewing the auctioned items on Christie's site, people could still make bids and the event was considered a success.
It now appears that the incident was the result of an attack conducted as part of a relatively new ransomware operation named RansomHub.
RansomHub listed Christie's on its Tor-based leak website - along with a few other organizations - on Monday.
The cybercriminals claim to have stolen 2 Gb of data from the auction house and are threatening to make it public in less than a week unless a ransom is paid.
A screenshot posted by the hackers suggests that they have obtained a database containing personal information such as name, date of birth, address, nationality, and data from identification documents such as passports.
In a statement to SecurityWeek, Christie's said the company experienced a technology security incident earlier this month and took swift action to protect its systems, which included taking its website offline.
