Hackers attacked the websites of two of the largest telephone service providers T-Mobile and Telefónica O2 on Thursday morning. A Telefónica spokesperson said that the attack had come from an IP address in Russia. The attack is under investigation by Czech police and security services. Every day of this week, web servers of various Czech institutions have been attacked – news sites, the search engine Seznam.cz, and financial institutions. According to some experts, this type of an attack is fairly primitive, though effective and hard to trace.
