The Evolution of Ransomware: From WannaCry to AI-Powered Attacks
How ransomware has evolved over the past decade and what the emergence of AI means for future threats.
The Ransomware Timeline
From CryptoLocker in 2013 to today's sophisticated RaaS operations, ransomware has undergone remarkable evolution.
Early Days: 2013-2016
The first modern ransomware families emerged with CryptoLocker, introducing strong encryption and Bitcoin payments. Key characteristics included:
The WannaCry Era: 2017
WannaCry marked a turning point, combining ransomware with the EternalBlue exploit for worm-like propagation. This demonstrated the potential for mass-scale ransomware attacks.
Modern Ransomware: 2020-Present
Double Extortion
Groups like Maze pioneered double extortion - encrypting data AND threatening to leak it publicly. This made backups alone insufficient as a defense.
Ransomware-as-a-Service (RaaS)
Operations like LockBit, BlackCat, and REvil operate as franchise models, enabling less technical criminals to launch sophisticated attacks.
Big Game Hunting
Targeted attacks against large organizations with deep pockets and critical infrastructure.
AI and the Future

Conclusion
Ransomware will continue to evolve, but so will our defenses. Understanding the threat landscape is the first step toward effective protection.
