By Ionut Arghire on April 05, 2021 China-linked cyber-espionage group Cycldek is showing increasing sophistication in a series of recent attacks targeting government and military entities in Vietnam, according to a report from anti-malware vendor Kaspersky. Active since at least 2013 and also referred to as Goblin Panda and Conimes, Cycldek is known for the active targeting of governments in Southeast Asia, and their preference for targets in Vietnam. In June last year, the group was revealed to have used a piece of custom malware to exfiltrate data from air-gapped systems, a clear sign of evolution for a group considered less sophisticated. The more recent attacks, Kaspersky says, show further increase in sophistication.
