It’s been five years since the WannaCry ransomware attack spread like wildfire, encrypting hundreds of thousands of important and high-profile systems.
More than 200,000 devices across 150 countries were encrypted in just 24 hours on May 12, 2017, according to Digital Shadows. After files were encrypted, a ransom note appeared on compromised devices with a ransom of $300-600, albeit less than the average ransom demands at the time.
