In this episode, we're talking about a significant development in the cyber threat landscape. There has been a surge in activity from a group known as Midnight Blizzard, also known as APT29. They're a sophisticated Russian state-sponsored group, and their primary targets are governments, diplomats, NGOs, and IT service providers, mainly in the US and Europe. What's really alarming is their recent shift in tactics. They're now using malicious RDP files in their spear-phishing campaigns, which is a new approach for them. This indicates they are evolving their methods, becoming even more dangerous. RDP is commonly used in corporate environments for remote access to resources, so many organizations have it enabled and may not be blocking RDP files, making them an ideal attack vector.
