Analyzing cryptocurrency data, a research group has estimated a lower-bound on 2020 ransomware revenue: $350 million, four times more than in 2019.

Based on the company’s data, among last year’s top earners, there were groups like Ryuk, Maze (now-defunct), Doppelpaymer, Netwalker (disrupted by authorities), Conti, and REvil (aka Sodinokibi).

Ransomware is now an established worldwide business.
