Background
A leading BFSI enterprise with operations in 50+ countries and handling billions of dollars in daily transactions faced a sophisticated cyber fraud campaign targeting its digital banking ecosystem.
Challenges
Fraudsters exploited gaps in transaction validation, customer authentication, and third-party payment integrations, using:
- Phishing and social engineering
- Credential stuffing attacks
- API manipulation to evade fraud detection
Internal Resistance: Siloed fraud monitoring across regions, lack of unified visibility between fraud prevention, IT security, and compliance teams.
External Resistance: Delayed fraud intelligence sharing from partner banks, payment gateways, and outsourced service providers.
Approach
- Conducted digital forensics to map the fraud execution lifecycle
- Performed fraud risk, Threat Review, Threat Modelling, Vulnerability Assessment, Penetration Testing, and API security assessment of payment workflows and integrations
- Deployed AI-driven fraud detection models using behavioural analytics
- Developed incident response playbooks for cross-team coordination
- Integrated SIEM, SOAR, Threat Intelligence, and Fraud Detection platforms for real-time prevention
Outcome
- 99.97% fraudulent transactions blocked before execution
- 62% faster detection-to-response cycle
- 24/7/365 global fraud monitoring across all customer-facing channels
- Strengthened authentication with adaptive multi-factor verification
- Achieved full compliance with PCI-DSS, GDPR, and local banking regulations
- Prevented over $1.2 billion in potential fraud losses within the first quarter of implementation
Impact
The organization shifted from reactive fraud handling to a proactive, intelligence-led defence, safeguarding customer trust, ensuring compliance, and protecting global operations from financial and reputational damage.
