Citizens Financial Group Data Breach via Third-Party Vendor
The Everest ransomware group posted data from Citizens Financial Group on its dark web leak site on April 20, 2026. The breach originated from a compromised third-party vendor, not the bank's internal systems. While most of the compromised dataset consisted of masked test data, a small subset of real customer data was affected, including names, addresses, and bank account numbers. Highly sensitive data like Social Security numbers or financial credentials were not indicated.
