In this week’s Cyber Security Brief, Dick O’Brien and Brigid O’Gorman discuss the implications of the Colonial Pipeline ransomware attack and the activities of the group behind it, Darkside. We also talk about what appears to be a reasonably new ransomware - Avaddon - that has been used in a string of attacks recently, while we also discuss an idea Brian Krebs wrote about that could potentially help deter ransomware actors from infecting your network. Away from the world of ransomware we talk about Lemon Duck and something of a resurgence in crypto mining, while we also discuss what CISOs are most worried about in 2021.
