Visa is warning that ransomware and AI-powered fraud are accelerating at an alarming rate. Cybercriminals now use generative AI to create highly convincing phishing messages and personalized scams, making it harder for individuals to spot fraud.
A 2025 survey found a 47% rise in AI-enabled cyberattacks. Financial services bore the brunt, accounting for 33% of all incidents. Additionally, 41% of ransomware families now include AI components, allowing malware to adapt and evade detection.
Visa operates AI fraud-detection systems that assign risk scores from 0 to 99 for every transaction. But attackers are now using adversarial AI to manipulate transaction patterns and bypass those defenses. This has become a cat-and-mouse game where both sides use machine learning.
The implications extend to crypto. Ransomware attackers almost universally demand Bitcoin or privacy coins. Increased ransomware activity fuels regulatory scrutiny, while also driving demand for blockchain analytics tools from firms like Chainalysis and Elliptic.
For individual users, generative AI can now produce phishing messages and fake websites that pass the eye test. Multi-factor authentication and hardware security keys are no longer optional but baseline necessities.
