WASHINGTON - Extremist groups that have long used the Internet to spread propaganda are increasingly tapping the Web to teach Islamic extremists how to be hackers, recruit techies for cyberwarfare, and raise money through online fraud, U.S. officials say.
A senior defense official said intelligence reports indicate extremist groups are seeking computer experts, including those capable of breaching government or other sensitive network systems.
The official, who spoke on condition of anonymity to discuss intelligence reports about the recruiting, said the extent and success of those recruiting efforts were unclear.
But jihadists' interest in hacking is evident in forums across the Internet. Law-enforcement officials say extremists are branching out into Internet fraud to raise money for their operations.
One Internet forum, the Mujahedeen Electronic Net, offers hacking instructions in a number of postings. A lengthy posting markets a weekly course and limits it to regular contributors to the Web site who confirm they are committed to Islam. The author of the offer says the course will be taught by "experts in the electronic jihad," according to a translation of the posting.
Last week, U.S. and Italian authorities broke up an international telephone fraud ring that had roots in Italy and employed hackers in the Philippines. The operation is believed to have funneled thousands of dollars to extremist groups in Southeast Asia.
Italian officials drew a fragile link to Osama bin Laden. They said one of the men charged with financing the hacking scheme had close ties to members of the International Islamic Efforts Foundation, a Philippines-based group linked to an Islamic charity organization once headed by one of bin Laden's brothers-in-law, Muhammad Jamal Khalifa. Khalifa was reported killed in 2007 during a burglary in Madagascar, where he had a sapphire business.
To date, experts say extremists largely have engaged in "sport hacking" - defacing or taking down Web sites belonging to groups they consider enemies, such as sites featuring Shiite, Jewish, or Christian beliefs.
"It's more for propaganda value than for tactical value," said Jarret Brachman, a former West Point researcher who is an expert on jihadist groups.
These "hacktivists" prefer to use the electronic media for advertising and spreading their beliefs. Internet sites that promote Islamic extremism abound, as do sites that instruct followers how to build bombs or conduct other types of attacks.
But some recent activity suggests there may be an aggressive push among extremists for expertise such as engineering and technical backgrounds that could be used against the U.S. government or other vital systems.
