A group of cybercriminals has breached and mapped the global banking system, and in a series of attacks has so far stolen $81 million from the central bank of Bangladesh.
Experts believe the attacks were done using fraudulent messages on a money transfer network connected to the banking system.
According to an insider with direct knowledge of the recent attacks, however, the culprit behind the digital bank robberies is much larger. The insider requested to remain anonymous due to security concerns, and was able to provide evidence to support his claims.
Investigations into the ongoing attacks are still underway, and related attacks on other banks are still being uncovered. Some experts are pinning the attack on hackers from North Korea, since the tools they used share similarities to the November 2014 hack of Sony Pictures Entertainment.
