Al-Qaeda Used Basic Codes, Calling Cards, Hotmail

"In startling revelations, convicted terrorist Ali Saleh Kahlah al-Marri admitted that Al Qaeda used public telephones, pre-paid calling cards, search engines and Hotmail. al-Marri 'used a "10-code" to protect the [phone] numbers — subtracting the actual digits in the phone numbers from 10 to arrive at a coded number.' The real story behind all this is that the terrorists weren't using sophisticated methods to avoid detection or monitoring — which tells us just how crappy SIGINT really is right now.
