Problem
P2P payment apps make money movement effortless—but also open doors for fraud. Behind everyday transactions, criminals build complex networks to launder money, hijack accounts, and exploit trust. Traditional rule-based systems can’t keep up. Fraud is dynamic, social, and constantly evolving. Your mission: help Viseca stay ahead by building an AI-powered model that detects suspicious behavior, uncovers hidden patterns, and adapts to new threats.
Objective Design a fraud detection system that goes beyond static rules. Your solution should:
- Model the network: Represent users and transactions as a graph to reveal suspicious structures.
- Spot anomalies: Assign risk scores to users or transactions based on behavioral patterns.
- Adapt to change: Build a model that generalizes to new fraud tactics—not just known ones.
- Explain your logic: Show why a transaction or user was flagged—transparency builds trust.
Support for Hackers

Technical Preferences
- The problem is well suited for graph-based methodologies. However, you have complete theoretical and technical freedom.
Why hack? Every fraudulent transaction has a human cost—someone’s rent, a small business’s payroll, a grandparent’s savings. Fraud is getting smarter. So must we. This is your chance to use AI for good: help Viseca protect millions by outsmarting evolving threats and building a safer digital finance future.
