The Russia-linked threat actor known as APT29 targeted European diplomatic missions and Ministries of Foreign Affairs as part of a series of spear-phishing campaigns mounted in October and November 2021.
According to ESET’s T3 2021 Threat Report shared with The Hacker News, the intrusions paved the way for the deployment of Cobalt Strike Beacon on compromised systems, followed by leveraging the foothold to drop additional malware for gathering information about the hosts and other machines in the same network.
Also tracked under the names The Dukes, Cozy Bear, and Nobelium, the advanced persistent threat group is an infamous cyber-espionage group that has been active for more than a decade, with its attacks targeting Europe and the U.S., before it gained widespread attention for the supply‐chain compromise of SolarWinds, leading to further infections in several downstream entities, including U.S. government agencies in 2020.
The spear-phishing attacks commenced with a COVID-19-themed phishing email impersonating the Iranian Ministry of Foreign Affairs and containing an HTML attachment that, when opened, prompts the recipients to open or save what appears to be an ISO disk image file (“Covid.iso”).
