How WannaCry Shapes Cybersecurity Today

WannaCry was a ransomware attack from 2017 that was not highly complex or innovative, but its rapid spread using the EternalBlue exploit caused significant damage worldwide. This incident was a wake-up call for cybersecurity, exposing vulnerabilities in common security frameworks and leading to collective defense efforts. Despite the discovery of a “kill switch” in the code, new versions of the attack targeted systems with the same Microsoft flaw, leading to a 53% increase in WannaCry attacks in early 2021.
