Our recent investigation at Certfa Lab, the APT42 has been running multiple phishing campaigns since late 2021 and some of them are ongoing and still active.

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.

InvisiMole has been collaborating with the Gamaredon APT for years.

* 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.
