The Czech Republic was recently hit by an unprecedented wave of cyber attacks, which left the investigators baffled over the origin of the attacks; in the midst of increasing concerns that the attacks could potentially cause chaos.

With the cyber attacks chiefly targeting banks, media, and telecommunications websites, an AFP report quoted National Cyber Security Centre's spokesman Radek Holy as saying that the, as of now, the investigators have no inkling about the motivation behind the attacks because the responsibility of the attacks has not yet been claimed by anyone.

Holy further added that "the character of the attacks gives us absolutely no clues about the reasons" behind their launch in the Czech Republic.

It was on Monday that a `distributed denial of service' (DDoS) attack was launched by hackers on prominent Czech news websites. The attacks blocked the servers of the targeted organizations by inundating them with hundreds of thousands of requests.

According to reports, Czech's most popular search engine - Seznam. cz - was targeted by the attacks on Tuesday; followed by the Prague Stock Exchange, the central bank and a number of commercial banks on Wednesday; and two national mobile operators on Thursday.

About the cyber attacks, Karel Kucharik - head of Czech's police cyber crime squad - said that the recent assault was apparently "the biggest attack of its kind in the Czech Republic since the Internet was launched."
