As reported by Censor.NET citing the press service of the National Security and Defense Council of Ukraine, this was stated by NSDC Information Security Office Head Valentyn Petrov in an interview with German ZDF TV channel.
"The cyber attacks on Ukraine were masterminded by the Russian special services and international hacking groups closely linked to them. In fact, the Russian Federation is testing a new system in Ukraine for bringing infrastructure facilities out of operation via cyberspace," he said.
Petrov noted that Ukraine started facing different types of cyber threats immediately after the Revolution of Dignity.
Moreover, Petrov stresses that when it comes to cyber attacks committed for the purpose of propaganda, they impact the entire society as propaganda has mass effect.
"However, our experts recorded that except for those cases which have become widely known, the massive attacks were committed on the banking sector - computer frauds, as well as the public authorities - cyber-espionage," he said, adding that all these cases were being investigated.
"We monitor the situation and obstruct attempts to gain unauthorized access to our hosts quite successfully," he stressed.
Petrov also noted that the number of cyber attacks would increase since the society embraced the digital age.
"Therefore, not only Ukraine but all other countries should take information security measures and steps to protect their systems from the outset."
As previously reported, the U.S.-based iSight Partners, which specialized on cyber intelligence, argued that the Russian group of hackers known as Sandworm was involved in the unprecedented blackout in Ukraine in late December 2015.
