From the EFF... [eff.org]

Sen. Ron Wyden has sent a letter [washingtonpost.com] to the U.S. Department of Justice concerning disruptions to 911 emergency services caused by law enforcement’s use of cell-site simulators [eff.org] (CSS, also known as IMSI catchers or Stingrays). In the letter, Sen. Wyden states that:

Senior officials from the Harris Corporation—the manufacturer of the cell-site simulators used most frequently by U.S. law enforcement agencies—have confirmed to my office that Harris’ cell-site simulators completely disrupt the communications of targeted phones for as long as the surveillance is ongoing. According to Harris, targeted phones cannot make or receive calls, send or receive text messages, or send or receive any data over the Internet. Moreover, while the company claims its cell-site simulators include a feature that detects and permits the delivery of emergency calls to 9-1-1, its officials admitted to my office that this feature has not been independently tested as part of the Federal Communication Commission’s certification process, nor were they able to confirm this feature is capable of detecting and passing-through 9-1-1 emergency communications made by people who are deaf, hard of hearing, or speech disabled using Real-Time Text technology.

The full text of the letter can be read here [eff.org].

Researchers of CSS technology have long suspected that using such technologies, even professionally designed and marketed CSS’s, would have a detrimental effect on emergency services, and now—for the first time—we have confirmation.

So not only does it snoop on all calls in the area, it also disrupts emergency calls. And why is everything about CSS, even its existence, such a huge secret, even to the point of dropping prosecutions?
