Paedophiles, terrorists, online fraudsters and criminal gangs are more and more turning to the internet to try to escape detection, police warn. Sophisticated criminals are aware that if they carry a mobile telephone, their every movement can be tracked using cell site analysis. Calls from traditional land line phones leave a record with billing companies.
But newer technologies, such as Skype, an internet-based mobile phone system, are much more difficult to track. The same is true of online games, forums and social networking sites, where criminals can meet, buy and sell stolen information and plot, often undetected. Reports said terrorists are learning the techniques paedophiles use to escape detection online and turning them to their own advantage. The Times reported terrorists were using websites carrying images of child exploitation, and even embedding coded messages in child porn images as a way to communicate secretly.
The web is also a haven for organised criminal gangs from Russia and China who target websites for blackmail and overload them with information to bring them down if the money is not paid. The DarkMarket site, which has been taken off-line, operated as a "virtual criminal network", police say. Beginners to the world of online fraud could gain expertise quickly, share tips with each other and buy bank and credit card details.
Entry to the site was password protected and by invitation only, keeping the number of users down to about 2,500. These people were scattered around the world, operating in western Europe, Asia and the US. The website was brought down in a three-year sting involving FBI agents and police forces in different countries.
The operation illustrates the difficulties police have in tracking online crime and the need for international co-operation. As the web becomes more complicated, and internet technology more sophisticated, the opportunities for cybercrime continue to grow.
