Sources of the Bulgarian National Radio claim that a Bulgarian institution has already become victim to the recent international cyber-attack. Bulgaria’s Chief Directorate Combating Organized Crime and the State Agency for National Security have been working on that case. Yesterday the Chief Directorate Combating Organized Crime already advised the citizens what to do if they fall victims to such cyber- attacks. Europol Director Rob Wainwright announced that the large-scale cyber- attack that started last Friday may continue on Monday. According to Europol, it has affected at least 100,000 organizations in 150 countries.
