Dhaka: Investigators probing the cyber theft of $81 million from Bangladesh's central bank have discovered evidence of unidentified hacking groups from North Korea, Pakistan and one other place inside the bank's network, Bloomberg reported, citing two people briefed on the progress of the bank's investigation.
FireEye Inc (FEYE.O), the company hired by the bank to conduct the forensics investigation identified digital fingerprints of the hacking groups, the two people said.
It was the third group, whose identity and country of origin is unknown, that pulled off the heist, according to reports.
FireEye has not found enough data to determine whether the third group, described by the company as the actual culprit, was a criminal network or the agent of another nation.
FireEye spokesman Vitor de Souza declined to comment.
