Hackers tied to the North Korean government have been observed using an updated version of a backdoor known as Dtrack targeting a wide range of industries in Germany, Brazil, India, Italy, Mexico, Switzerland, Saudi Arabia, Turkey and the U.S. "Dtrack allows criminals to upload, download, start or delete files on the victim host," Kaspersky researchers Konstantin Zykov and Jornt van der Wiel said in a report. Discovered in September 2019, the malware has been previously deployed in a cyber attack aimed at a nuclear power plant in India, with more recent intrusions using Dtrack as part of Maui ransomware attacks.
