On Thursday, March 7, the biggest cyber-attack in the history of the Czech Republic continued for a fourth day. After news websites and bank servers, hackers also switched off websites belonging to telecoms operators, the Sme daily wrote on March 8.
For 30 minutes, the website of Slovak mobile operator O2 experienced a blackout, as it shares a server with its Czech sister company.
In a rare public statement, Slovakia's SIS intelligence service confirmed that Slovakia also faces "risks". SIS spokesman Branislav Zvara said, according to Sme, that the SIS had informed "those concerned", but he did not specify who they were or what are the risks.
It is not clear what the hackers want to prove. There has been speculation that they may simply want to cause mayhem, or alternatively that the action may be an attempt to introduce harmful code onto corporate websites and servers.
