At FireEye, we’ve been observing an increased use of ransomware for a while now. Some factors contributing to the rise include high profit margins coupled with low overhead, the financial success of ransomware families such as CryptoWall, the emergence of ransomware variants adopting a ransomware-as-a-service framework, and the major media coverage of high-profile ransomware attacks.
Just this year we’ve seen WannaCry ransomware spread fast and infect countless machines using the now infamous EternalBlue exploit that was revealed in the Shadow Brokers leak. Then, about a month later, EternalPetya ransomware did the same thing. When considering how financially successful and widely reported these attacks were – as well as 2016 attacks against hospitals and other major entities – then it’s not hard to see why threat actors continue to rely on this tricky type of malware.
