In an announcement Mr Simkhai mentioned maintaining his program protect from hackers got a “number one concern”.
Making use of scientific ways and appropriate behavior their team got “blocked the annoying internet site and hacker”.
“Our company is vigilantly monitoring for hacking and now we’ve added committed they protection experts to your group,” the guy said. “when you look at the coming days, we will getting running aside a major safety update to our program.”
