The top 10 ranking was compiled using telemetry data gathered during 2015 from Symantec security products and includes details about bot-infected PCs, Macs, smartphones, tablets and connected smart devices.
Based on the number of total bots in one specific city, Istanbul, Turkey was the most infected city, with the largest number of detected bots, followed by another Turkish city, Ankara, the country’s capital.
Taking into account the number of Internet users in each country, and comparing this data with the number of detected bots, we get a “bot density” factor that provides a more accurate reflection of which countries do an appalling job at securing their computers and connected devices.
