On this week’s Cyber Security Brief, Dick O’Brien and Brigid O’Gorman are joined by Symantec threat researchers Vikram Thakur and Alan Neville. Vikram discusses Symantec’s role in the cross-industry initiative to disrupt the Trickbot botnet. Symantec was part of a global partnership that secured a court order directing hosting providers to take down Trickbot’s infrastructure. Trickbot had spread prolifically across the internet for years and became one of the most commonly blocked types of malware, suggesting it was one of the world’s largest botnets. Alan is on the podcast to discuss some newly-published Symantec research into Seedworm, as the Iran-linked group continues to target organizations in the Middle East, while we also chat about some of the indictments that have recently been announced against various nation-state backed actors around the world.
