Obama doesn't want you to have privacy using a cellphone

The Obama administration is arguing in court that there is no expectation of privacy while using a cell phone. That is, the administration wants to track you without probable cause or a warrant. As usual, the EFF and the ACLU seem to be the only people that care...

Government can Track your Location Without Telco Help

Law enforcement agencies have been installing "Triggerfish" cell phone tower simulators which force cell phones to reveal unique identifiers. In other words, they now have the ability to track your location if you are carrying a cell phone. This requires a court order, but we all know how that story goes -- nowadays those are viewed as completely optional by those in power (not that they are all that hard to obtain anyways).

This wouldn't be all that significant (compared to other things we know about government surveillance) except that this monitoring technology is unique in that the government does not require the cooperation of any telco company to use it.

Point and Click Surveillance

Wired has an excellent article on the FBI's surveillance system used to eavesdrop on anyone with a cellphone. Some of the pictures are particularly revealing; they show how simple it is to use this powerful system. Some commentary on the system from the article:

Columbia's Bellovin says the flaws are appalling and show that the FBI fails to appreciate the risk from insiders.

"The underlying problem isn't so much the weaknesses here, as the FBI attitude towards security," he says. The FBI assumes "the threat is from the outside, not the inside," he adds, and it believes that "to the extent that inside threats exist, they can be controlled by process rather than technology."

Bellovin says any wiretap system faces a slew of risks, such as surveillance targets discovering a tap, or an outsider or corrupt insider setting up unauthorized taps. Moreover, the architectural changes to accommodate easy surveillance on phone switches and the internet can introduce new security and privacy holes.

"Any time something is tappable there is a risk," Bellovin says. "I'm not saying, 'Don't do wiretaps,' but when you start designing a system to be wiretappable, you start to create a new vulnerability. A wiretap is, by definition, a vulnerability from the point of the third party. The question is, can you control it?"

Well it's a good thing that we can completely trust the FBI to understand the scope of its responsibilities and the limits of its power because it has never abused the privileges entrusted to it in the past. Oh, wait.

Your cellphone is listening... even when it's off

The FBI is pulling some sweet new tricks on mob bosses. Cell phones can be made to listen in on conversations even when they are turned off. This is just another reminder, however, of how easy it is for law enforcement to monitor us with today's technology. Let's hope that mob bosses are the only ones that they choose to monitor, and not deploy it on a much wider, illegal scale...
