As Bitcoin Price Surges, DDoS Extortion Gangs Return in Force

Extortion groups that send emails threatening companies with DDoS attacks unless paid a certain fee are making a comeback, security firm Radware warned today. From a report: In a security alert sent to its customers and shared with ZDNet this week, Radware said that during the last week of 2020 and the first week of 2021, its customers received a new wave of DDoS extortion emails. Extortionists threatened companies with crippling DDoS attacks unless they got paid between 5 and 10 bitcoins ($150,000 to $300,000).

Radware said that some of the emails it seen were sent by a group that was active over the 2020 summer when the extortionists targeted many financial organizations across the world. Companies that received this group’s emails last summer also received new threats over the winter, Radware said. The security firm believes that the rise in the Bitcoin-to-USD price has led to some groups returning to or re-prioritizing DDoS extortion schemes.
