KPMG refutes alleged Nova ransomware hack of Dutch branch

UK multinational professional services network KPMG has repudiated claims made by the Nova ransomware gang purporting the breach of KPMG Netherlands, according to Techzine.

No additional details on the extent of the hack were provided by Nova, which only threatened to expose KPMG Netherlands' data should the firm refuse to pay the demanded ransom within 10 days.

"We are aware of claims on social media alleging that KPMG data has been accessed. The IT infrastructure and security systems managed by KPMG have not been compromised. KPMG takes cybersecurity seriously and we will continue to monitor the situation closely," said KPMG.

Dutch lab Clinical Diagnostics had data from over 850,000 individuals compromised following an attack by Nova last year, with the ransomware operation leaking certain data even after the ransom was fulfilled. Nova also targeted Dutch software firm FysioRoadmap in an attack that led to the exposure of information from more than 20,000 patients.
