Summary: Intelligence reports indicate terrorist groups that have long used the Internet to spread propaganda are increasingly tapping the Web to teach Islamic extremists how to be hackers, recruiting techies capable of breaching government or other sensitive network systems for cyberwarfare, and raising money through online fraud.
The terrorism threat to the United States over the next five years will be driven by instability in the Middle East and Africa, persistent challenges to border security, and increasing Internet savvy — with chemical, biological, radiological, and nuclear [CBRN] attacks considered the most dangerous threats — according to a Homeland Security Threat Assessment for the years 2008-2013.
