Most cyber attacks in the second quarter came from Europe, with Italy the source of most mobile-based attacks, says online content distributor Akamai.
Akamai's state of the internet report for Q2 2010 showed that while the US led Russia and China as the main sources of cyber attacks, on a continental basis Europe led with 39% of attacks.
Akamai's report is based on traffic hitting its global server network, and provides a practical snapshot of key internet statistics such as broadband adoption, mobile connectivity and attack traffic, as well as trends.
It said seven European countries are among the world top 10 for average connection speeds. They were Romania (6.8Mbps), Netherlands, Latvia, Sweden, Czech Republic, Belgium and Denmark.
In raw speed, the Netherlands was third behind South Korea and Japan. It said 31 countries had more than 10% of users getting above 5Mbps.
"Significant growth in connections to Akamai at speeds above 25Mbps were observed in the Netherlands (up 12%), Romania (up 25%) and Belgium (up 21%)," it said.
Sweden's high broadband adoption was down 21% and it was the only country in the top 10 to show a year-on-year decline.
The fastest city (at least 50,000 unique IP addresses connecting to Akamai) was Masan, South Korea, with an average connection speed of more than 20Mbps.
Umea in Sweden was the fastest European city (20 out of 100) with an average connection speed of 10.8Mbps, and 15 European cities made the list compared to just eight US cities. Romania had five cities in the top 100.
The US accounted for 11% of observed attack traffic, with China and Russia in second and third place respectively. Italy was the top source of attack traffic from known mobile networks, generating 25% of all observed mobile attacks.
Mobile broadband speeds varied from 6.1Mbps to 115kbps. Nineteen of the 109 mobile providers listed had average connection speeds of 2Mbps or faster, five more than in the first quarter.
Over 500 million unique IP addresses from 236 countries/regions connected to the Akamai network during the quarter. This was 2.8% more than in the first quarter of 2010, and 18% more than in the same quarter a year ago. Germany ranked fourth in the top country listing, with France (5), the UK (6) and Spain (10) also featuring.
