In this week’s Cyber Security Brief, Brigid O Gorman and Dick O’Brien discuss how Russian espionage actors are exploiting the Follina vulnerability, the release of the latest version of Metasploit, and a new phishing campaign that’s been underway on Facebook. We also discuss ransomware extensively, including what authorities were able to find when they took down the Netwalker ransomware gang, the increasing activity of the BlackCat ransomware, and some new research into the Hello XD ransomware. We also speculate about the impact turmoil on the cryptocurrency markets may have on the types of payment ransomware actors might demand.
