ScarCruft, an anti-North Korean Hacking Team, was exposed by Kaspersky Lab for establishing espionage campaigns using Bluetooth exploits. The group has targeted government officials and businessmen operating in the Korean peninsula through Bluetooth. The operation apparently started in 2018, with the use of a specially designed modular malware, composed of many modules in its goal of evading detection. A Hong Kong government diplomatic agency which has strong ties with North Korea was also reported of falling for the same espionage campaign. An unnamed public agency in Russia also had signs of malware infection that were similar to the one reported by the same North Korean agency.”]
