US using fake mobile phone towers on planes to gather data
Devices nicknamed ‘dirtboxes’ can collect information from tens of thousands of mobile phones in a single flight

An agency of the US Justice Department is gathering data from thousands of mobile telephones, including both criminal suspects and innocent Americans, by using fake communications towers on planes, according to a newspaper report.
The programme run by the US Marshals Service began operations in 2007 and uses Cessna planes flying from at least five major airports and covering most of the US population, the Wall Street Journal said on Thursday, citing people familiar with the operations.
The planes use devices made by Boeing that mimic mobile phone towers used by major telecommunications companies and trick mobile phones into revealing their unique registration data, the report said.
The devices, nicknamed “dirtboxes,” can collect information from tens of thousands of mobile phones in a single flight, which occur on a regular basis, according to those with knowledge of the programme, the Journal said.
It said a Justice Department official would not confirm or deny the existence of such a programme, saying such discussion would allow criminal suspects or foreign powers to determine US surveillance abilities, but that department agencies comply with federal law, including by seeking court approval.
The programme is similar to one used by the National Security Agency which collects the phone records of millions of Americans in order to find a single person or a handful of people.
The Journal cited the people familiar with the programme as saying that the device used in it decides which phones belong to suspects and “lets go” of non-suspect phones.
Although it can interrupt calls on some phones, authorities have made software changes to make sure it doesn’t interrupt anyone calling the 911 emergency number for help, one person familiar with the matter said, the Journal reported.
It also bypasses telephone companies, allowing authorities to locate suspects directly, people with knowledge of the programme said.
The report quoted Christopher Soghoian, chief technologist at the American Civil Liberties Union, as calling it “a dragnet surveillance programme. It’s inexcusable and it’s likely, to the extent judges are authorising it, they have no idea of the scale of it.”
The newspaper said it was unknown what steps are being taken to ensure data collected on innocent people is not kept for future perusal by authorities.
