Unveiling an unknown APT actor attacking high-profile entities in Europe and Asia

ToddyCat is a relatively new APT actor that we have not been able to relate to other known actors, responsible for multiple sets of attacks detected since December 2020 against high-profile entities in Europe and Asia. We still have little information about this actor, but we know that its main distinctive signs are two formerly unknown tools that we call ‘Samurai backdoor’ and ‘Ninja Trojan’.

Here we go with another episode about our (not so) old friend, BRATA. In almost one year, threat actors (TAs) have further improved the capabilities of this malware. In our previous blog post [1] we defined three main BRATA variants, which appeared during two different waves detected by our telemetries at the very end of 2021. However, during the last months we have observed a change in the attack pattern commonly used.

Researchers looking into a new APT group targeting gambling sites with a variety of cross-platform malware recently identified a version of oRAT malware targeting macOS users and written in Go. While neither RATs nor Go malware are uncommon on any platform, including the Mac, the development of such a tool by a previously unknown APT is an interesting turn, signifying the increasing need for threat actors to address the rising occurrence of Macs among their intended targets and victims. In this post, we dig deeper into the technical details of this novel RAT to understand better how it works and how security teams can detect it in their environments.

• Proofpoint has identified a likely nation-state sponsored phishing campaign using a possibly compromised Ukrainian armed service member’s email account to target European government personnel involved in managing the logistics of refugees fleeing Ukraine.
• The email included a malicious macro attachment which attempted to download a Lua-based malware dubbed SunSeed.
• The infection chain used in this campaign bears significant similarities to a historic campaign Proofpoint observed in July 2021, making it likely the same threat actor is behind both clusters of activity.
• Proofpoint is releasing this report in an effort to balance accuracy with responsibility to disclose actionable intelligence during a time of high-tempo conflict.
