Nova Ransomware Group Claims Attack on KPMG, Threatens to Leak 500GB of Data

The Nova ransomware group has claimed responsibility for an attack against KPMG, one of the Big Four professional services firms, threatening to release 500GB of stolen data if ransom demands are not met.

The listing appeared on Nova's dark web leak site on January 23, 2026, with a 10-day countdown timer. The group claims to have exfiltrated business services data and has provided samples as proof of compromise. A tree structure of the allegedly stolen files is also available for download.

KPMG provides audit, tax, and advisory services to many of the world's largest organizations. KPMG LLP North America operates as the independent U.S. member firm of KPMG International Cooperative.

Nova Ransomware Background

Nova, formerly known as RALord, is a fast-growing ransomware-as-a-service operation that emerged in late 2024. The group employs double-extortion tactics—encrypting victim systems while exfiltrating data to pressure payment.

The operation heavily targets the IT, technology, manufacturing, and healthcare sectors, with previous victims in the UAE, France, Singapore, and the United States.

KPMG has not publicly confirmed the incident. This story will be updated if additional information becomes available.
