How Ransomware Works

Ransomware Spotlight: WannaCry

WannaCry (aka WannaCrypt, WCry, WanaCrypt0r 2.0, Wanna Decryptor) is yet another ransomware variant. This particular strain was coupled with a Windows exploit dubbed EternalBlue which allowed it to automatically propagate itself to vulnerable machines across the internet beginning on May 12, 2017, when the first wide-scale infections began. Perhaps the most high-proflle compromise to-date has been the large swath of health care institutions in the UK that were essentially shut-down and rendered unable to provide care to their patients. While not technically advanced, the use of the EternalBlue created a ransomworm that spread much faster than any other previously reported ransomware outbreak.

How Cylance blocks WannaCry

CylancePROTECT immediately prevented the execution of WannaCry on all of our customer’s endpoints. How? By leveraging machine learning and artificial intelligence to predict malicious code pre-execution without relying on a signature, heuristic ruleset, cloud connection, or any of the methods used by traditional antivirus products.
