LAS VEGAS, Nev., Aug 11 (Reuters) - Ukraine's top cyber official addressed a room full of security experts at a hackers' convention following a two-day trip from the capital, Kyiv, to a golden online casino in Las Vegas.
During his unannounced visit, Victor Zhora, online casino the deputy head of Ukraine's State Special Communications Service, told the so-called Black Hat convention on Wednesday that the number of cyber incidents to have hit Ukraine tripled in the months following Russiaґs invasion of his country in late February.
"This is perhaps the biggest challenge since World War Two for the world, and it continues to be completely new in cyberspace," Zhora told an audience at the annual conference.
Ukraine faced a number of "huge incidents" in cyberspace from the end of March to the beginning of April, Zhora said, including the discovery of the "Industroyer2" malware which could manipulate equipment in electrical utilities to control the flow of power.
Russian hackers also hit Ukraine at the onset of the war though a cyberattack that took down regional satellite internet service.
