: Captured jihadist geek reveals al Qaeda’s web strategy (hey, doesn’t everybody have a web strategy?):

U.S. sources said Khan told interrogators al Qaeda uses Web sites and e-mail addresses in Turkey, Nigeria and tribal areas of Pakistan to pass messages among themselves.

Couriers were often used to deliver computer discs, and Khan would then post the messages on Web sites, but only briefly, the sources said.

According to the sources, after messages were sent and read, the files were deleted.

E-mail addresses were used only two or three times; if the information was really sensitive, an address might be used only once.
