Is ransomware winning?

Abstract

This paper evaluates the performance of ransomware attacks and looks at the tactics and successes to determine effective counterstrategies. By analysing lagging indicators of the successes of ransomware, we can reverse-engineer an effective counterstrategy to fight back and significantly reduce the effectiveness of ransomware. This paper argues that the biggest challenge in countering modern ransomware is that the approach most companies are taking is too narrow. There is no one solution answer to this challenge. The most effective counter to modern ransomware is a balanced security strategy of preventative and detect and response, layered in such a way as to disrupt, reduce and eliminate the tools and tactics that make modern ransomware effective. This also includes activities that happen well in advance of the ransomware attack and devices that may not even be part of the actual attack itself. This paper will also propose an effective strategy to counter modern ransomware and provide organisations with key technologies to remove critical capabilities from our adversary’s arsenal and disrupt the tactics that have made modern ransomware so successful.
