Russian Group of Hackers reportedly cracked into the Kazan-based Energobank and messed up with the Ruble-Dollar exchange rates.
In Feb 2015, a hacking group, known by the name METEL, successfully breached into the Russian Regional Bank for just 14 minutes and caused the exchange rate to fluctuate between 55 and 66 rubles per dollar, which finally resulted in the increment of Ruble’s value.
