MOSCOW (Reuters) - Russia's No. 2 bank VTB was hit by the largest cyber attack in its history, it said on Tuesday, warning of temporary difficulties in accessing its mobile app and website, but assuring customers that their data remained safe.

State-owned VTB said it was repelling the distributed denial of service (DDoS) attack, in which hackers attempt to flood a network with unusually high volumes of data traffic in order to paralyse it.
