New research about the Yanluowang ransomware and two separate campaigns targeting victims in Asia

On this week’s Cyber Security Brief, Brigid O Gorman and Dick O’Brien discuss several new blogs that the Symantec Threat Hunter Team has published recently. Firstly, we uncovered a new ransomware threat that we dubbed Yanluowang, which appears to be deployed in a targeted fashion and is certainly a new threat as various indications point towards it still being in development. We also published two blogs detailing two separate campaigns targeting organizations in Asia. The Harvester group is a previously unknown, likely nation-state backed group targeting victims in South Asia, while elsewhere a new espionage campaign is targeting the defense, healthcare, and ICT sectors in South East Asia. Meanwhile, we also discuss new activity from a targeted attack group dubbed LightBasin, and the return of the Lyceum group.

Kaseya ransomware supply chain attack, new SolarWinds vulnerability, and the rising cost of cyber insurance

On this week’s Cyber Security Brief, Gavin O’Gorman joins us to discuss the Kaseya ransomware supply chain attack that occurred over the July 4 holiday weekend in the U.S. The REvil/Sodinokibi ransomware gang were behind this attack, and Gavin and Dick O’Brien discuss whether this is a sign that we now need to be aware of ransomware actors targeting victims through supply chain attacks, which would more traditionally be associated with state-sponsored hackers, as well as some of the other interesting aspects of this attack. Meanwhile, Brigid O Gorman discusses the latest news of a new vulnerability in SolarWinds software being exploited by a Chinese hacking group, energy companies being targeted in a year-long espionage campaign, and the rising cost of cyber insurance.
