FBI warned US banks on cyberattacks after Bangladesh heist

More breaches: A malicious cyber group had compromised the networks of multiple foreign banks.

The US Federal Bureau of Investigation last month urged banks to look for signs of possible cyberattacks in the wake of the massive heist at Bangladesh's central bank, asking them to hunt for technical clues that they have been targeted by the same group.

The private "Flash" notification, which provided technical information about the attacks, said a "malicious cyber group" had compromised the networks of multiple foreign banks.
