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.
