RansomHub group says it was behind Christie's attack, threatens to release private data of half a million customers

A laptop with a red screen with a white skull on it with the message: "RANSOMWARE. All your files are encrypted.".

The recent cyberattack at auction house Christie’s, which took the company’s website offline hours before a major event, appears to now be confirmed as a ransomware incident.

A hacking collective calling itself RansomHub has claimed responsibility for the attack, also saying it stole sensitive information about Christie’s customers.
