In this week’s Cyber Security Brief, Dick O’Brien and Brigid O’Gorman talk about some of the biggest cyber security stories of the last couple of weeks. There are multiple stories about APT groups to cover this week, including our own Threat Intel blog detailing a wide-ranging attack campaign that targeted Japan-linked companies in multiple sectors in 17 regions worldwide. We also discuss other public reports about a Chinese APT targeting governments in South East Asia, and nation-state backed attacks from Russia and North Korea targeting COVID-19 vaccine makers and researchers. We also discuss a separate campaign in which Lazarus is targeting victims in South Korea, and examine some developments in the world of ransomware.
