Session
Known for hacking many industries as well as developing their own custom tooling, the Russian-based threat actor known as Turla uses a stealthy Microsoft Exchange backdoor called LightNeuron. Using standard mail protocols, steganography and an unconventional mail rule engine (to name a few), in this talk I’ll demonstrate a re-imagination of this complex backdoor while extending it to be used with Cobalt Strike. All this while asking, what does this mean for detection engineering?
