The extortion group ShinyHunters listed US data center operator CyrusOne on its leak site in August 2026, claiming it stole 12.9 million Salesforce records, hundreds of gigabytes of SharePoint data, employee records, contracts, and data center floor plans, and demanding $13 million. As of reporting, CyrusOne had not publicly confirmed or denied the claim and the group had released no data samples to substantiate it. This record is unverified: the alleged breach rests entirely on the attackers' claims.
