Summary

In 2025, 90% of breaches in the financial sector were financially motivated, with data breaches at 64% and ransomware at 36%. The average cost of a data breach in this sector reached $5.56 million, making it the second-most expensive industry for breaches. AI-related threats, particularly Shadow AI, contributed to 20% of these incidents, while third-party compromises were involved in 30% of breaches. The rise of double-extortion ransomware tactics has become a significant concern, with 12.8% of B2B financial organizations affected. The EU's Digital Operational Resilience Act (DORA) is now enforceable, requiring financial institutions to adopt intelligence-led risk management and conduct threat-led penetration testing. Continuous intelligence sharing and attack simulations across vendor ecosystems are recommended to mitigate these risks. Key Points: • 90% of financial sector breaches in 2025 were financially motivated. • The average cost of a data breach in finance reached $5.56 million. • Double-extortion ransomware tactics are now dominant against financial institutions.
