RansomHub claims attack on Christie’s, the world’s wealthiest auction house

RansomHub has claimed responsibility for a cyberattack on auction house Christie’s, posting alleged stolen data on its extortion site; Christie’s confirmed unauthorized access and that a limited amount of client personal data was taken but said there is no evidence financial or transactional client data were copied. The company has taken its website offline during investigation, will notify affected clients and regulators, and the incident is noted amid a broader surge in ransomware attacks in the UK.
