Researchers may have found a link between Moonlight Maze of the late 90s and the Turla APT. Researchers presented more evidence that could ultimately and definitively connect one of the earliest cyberespionage campaigns on record to the Russian-speaking APT. Turla is proficient in stealing secrets from sensitive Western targets through the use of hijacked satellite links, watering hole attacks, a host of covert backdoors, and advanced malware. Turla would elevate Turla to the ranks of the Equation Group as an elite nation-state attacker.
