Case Study: Top 5 UK Bank Stops Advanced Fraud with BioCatch Behavioral Biometrics

BioCatch puts the brakes on a sustained cyber attack and produces demonstrable results for Top 5 UK bank

Top 5 UK Bank was facing a prolonged cyber attack involving Dridex malware that could take over customer accounts and bypass traditional fraud controls such as malware detection, transaction monitoring, and device fingerprinting. BioCatch provided behavioral biometrics to detect suspicious activity based on how users interacted with the banking session, not just the device or location.

BioCatch identified anomalous behavior inside a high-risk session, including unusual field selection, scrolling patterns, and disrupted hand-eye coordination that signaled remote access fraud. The solution generated a real-time alert that helped the bank stop an attempted £1.6M fraudulent transaction, and during the pilot the bank achieved a 23x ROI, 81% fraud detection rates, and a false positive rate of just 0.05%.
