jd writes "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. If the NSA needs to wiretap the whole of the US because they can't break into a Hotmail account, you know they've got problems. FindLaw has a copy of al-Marri's plea agreement (the tech-related information begins on page 12), and the LA Times has further details on his case."
