Hackers claim to have breached the largest commercial bank in Ukraine

A group of hackers called Green Dragon Crew announced on Twitter that the recent cyberattack on Privatbank, the largest commercial bank in Ukraine, was their own achievement.

The attack appears to involve a distributed denial of service since on June 30, for a few hours, the bank's pages did not load or customers had limited access.

However, the group also claims to have managed to breach the bank's systems and access customer bank accounts. To do this, however, they would need to access different systems, as the payment service and the website are not part of the same infrastructure.
