Earth Koshchei Coopts Red Team Tools in Complex RDP Attacks


Red teaming provides essential tools and testing methodologies for organizations to strengthen their security defenses. Cybercriminals and advanced persistent threat (APT) actors pay close attention to new methods and tools red teams develop, and they may repurpose them with a malicious intent.

In October 2024, an APT group that Trend Micro tracks as Earth Koshchei (also known as APT29 and Midnight Blizzard), likely used a rogue remote desktop protocol (RDP) attack methodology against numerous targets. This methodology was described earlier in 2022 by Black Hills Information Security in detail. The attack technique is called “rogue RDP”, which involves an RDP relay, a rogue RDP server, and a malicious RDP configuration file. A victim of this technique would give partial control of their machine to the attacker, potentially leading to data leakage and malware installation.
