In this week’s Security Ledger Podcast (#88) we do a deep dive with researcher Vikram Thakur of the firm Symantec on “Dragonfly,” the Russian hacking group whose actions prompted the U.S. Department of Homeland Security and the FBI to issue a joint statement last week warning of intrusions into critical infrastructure in the US. Also: how do cyber criminals cash out all the loot they make from online scams? In our second segment we’ll talk to researcher Mike McGuire of the University of Surrey, who has been studying that question.
