KIEV, Feb. 13 - Not a single DDoS-attack on the state registers has led to the alteration of the data stored there, Ukrainian Justice Minister Pavlo Petrenko told Interfax.

"There were quite a lot of DDoS-attacks on our registers last year, but there was no external interference in the register itself in any case. So, these DDoS-attacks were unsuccessful. When they saw that the register does not work, it was an external attack, it was a load on the register, not a single instance of successful data change in the register was uncovered," he said.
