"Friends, we've been DDoSed," the company said in a post on Tuesday."During the first wave of the attack, which began yesterday in the morning, our IT services could normalise the situation, and after 17:00, all the services on the site worked properly.
"But today, hackers are at it again. Due to their actions, both the website and services are working, but slowly and with interruptions."
Ukraine has suffered a couple of cyber attacks this year. In June this year Ukraine was heavily hit by the Notpetya ransomware attacks, with most of the attacks targeting Public transport services, banks, Power and television stations.
Some few days ago, the Ukrainian cyber police arrested a man accused of facilitating the spread of the Peyta virus.
