| WannaCry had little impact in Slovakia |
| Bratislava, 07.06.2017 |

| Three good tips for online security.
In mid May computers of national railways in Germany, mobile operators in Spain and Hungary and hospitals in the United Kingdom were infected by the WannaCryptor ransomware, leaving them with the message “Ooops, your files have been encrypted!” on their screens. The ransomware encrypted their files and demanded payment of $300 in bitcoin to get them back. In Slovakia only a hospital in Nitra reported infected computers.
We spoke with Ondrej Kubovič, security evangelist at the Slovak security software company ESET about the ransomware WannaCryptor, also known under the name WannaCry, and the best ways to keep yourself protected from cyberthreats.
The Slovak Spectator (TSS): What exactly happened when the ransomware WannaCryptor attacked computers on May 12?
Ondrej Kubovič (OK): Actually two things happened there. First the EternalBlue exploit was leaked sometime in February from America’s National Security Agency (NSA). It is believed that it was used for espionage. This tool abused vulnerability in the Windows operatingsystems that it no longer supports, like Windows XP or Windows 8. But people using these unsupported systems had to install the patch on their own and in many cases that was not done. This is why there were so many vulnerable computers.
TSS: How many computers were infected?
OK: Based on data published by Europol, WannaCryptor infected over 200,000 computers in 150 countries around the world, which is not an extremely high number. What earned it such extensive coverage was that it infected computers in sensitive institutions like mobile operators in Spain and Hungary or health-care related organisations in the UK. It is estimated that the hackers who were behind the attack received some $120,000, which is not a huge amount of money. From this point of view, this was rather faulty implementation. But there are also speculations that WannaCryptor was leaked on the web when it was only in its testing phase.
