If you are an aspiring terrorist, beware of using your credit card at Bombs R Us and certainly do not join the al Qaeda loyalty program for discounts. The government is watching the use of credit cards, calling cards, and loyalty cards. From Wired:
Federal law enforcement agencies have been tracking Americans in real-time using credit cards, loyalty cards and travel reservations without getting a court order, a new document released under a government sunshine request shows.
The document, obtained by security researcher Christopher Soghoian, explains how so-called “Hotwatch” orders allow for real-time tracking of individuals in a criminal investigation via credit card companies, rental car agencies, calling cards, and even grocery store loyalty programs. The revelation sheds a little more light on the Justice Department’s increasing power and willingness to surveil Americans with little to no judicial or Congressional oversight.
For credit cards, agents can get real-time information on a person’s purchases by writing their own subpoena, followed up by a order from a judge that the surveillance not be disclosed. Agents can also go the traditional route — going to a judge, proving probable cause and getting a search warrant — which means the target will eventually be notified they were spied on.
The document suggests that the normal practice is to ask for all historical records on an account or individual from a credit card company, since getting stored records is generally legally easy. Then the agent sends a request for “Any and all records and information relating directly or indirectly to any and all ongoing and future transactions or events relating to any and all of the following person(s), entitities, account numbers, addresses and other matters…” That gets them a live feed of transaction data.
The problem here isn’t necessarily the use of information of this type, but the nature in which it is being obtained without a warrant or judicial oversight. The judicial system is only being used to get an order to prevent disclosure of the surveillance after the federal agent has written his own subpoena to obtain the information.
