Technology is like a double- edged sword. While it's being used by the British intelligence to track them down, the Taliban are effectively exploiting the Internet phones to evade detection in war-ravaged Afghanistan.
The militants are using Skype, a popular piece of consumer software that allows free calls to be made over the web, to communicate with cells strung out across that country, the 'Daily Mail' quoted an intelligence source as saying.
"The trouble with this technology is that it is easily available but devilishly hard to crack. The technology can now be accessed on mobile Internet devices and the country's cell phone network is expanding rapidly," the unnamed source said.
In fact, according to him, intelligence agency MI6 is finding it virtually impossible to intercept calls, made via the Internet by the Taliban targeting British and US forces, as they are heavily encrypted.
Unlike traditional mobile calls, voice calls are broken into millions of pieces of data before being sent down the line and reassembled by the other caller's computer.
However, both Britain and America are investing considerable resources to crack the codes, and in the United Kingdom, the government is introducing legislation to force Internet service providers to log all web activity.
Even Sir David Pepper, the head of GCHQ, the British government's top-secret listening post, had told MPs recently that net calls are "seriously undermining" his organisation's ability to monitor Taliban communications.
However, Skype, the company which runs the software on the web, has refused to comment on the issue.
