According to a top government official, terrorists are preparing for an Internet war, designed to take down systems and create havoc in financial markets and defense systems. The result may be of far greater consequence than bombing.The senior defense official, who gave information anonymously to MSNBC, declares extremist groups are recruiting Islamic extremists and seeking experts who can breach government or other sensitive network systems for travel, communication and finances. In addition Internet fraud is used to raise money for this. One of these is a forum called Mujadedeen Electronic Net which gives hacking instructions, along with a weekly course.
