On this week’s Cyber Security Brief podcast, Brigid O Gorman and Dick O’Brien are joined by Symantec threat researcher Alan Neville to discuss the biggest cyber security story of the last couple of weeks - the vulnerabilities in Microsoft Exchange Server. Alan gives a comprehensive overview of the vulnerabilities, what’s happened since they became public knowledge last week, and the steps you can take to keep your organization’s network safe. He also talks about some of the post-compromise activity that Symantec has seen. We also chat about some other topics: new research into the SolarWinds hack, and the arrest of an alleged GandCrab ransomware gang member.
