Every year, security researchers, hardware hackers and other deep geeks from around the world converge on an English nature reserve for Electromagnetic Field, a hacker campout where participants show off and discuss their research and creations. Read the rest

An NBC investigative journalism team and a security researcher went wardriving around the DC area with a cell-site-simulator detector that would tell them whenever they came in range of a fake cellphone tower that tried to trick their phones into connecting to it in order to covertly track their locations (some cell site simulators can also hack phones to spy on SMS, calls and data).

In 2016, Motherboard used public records requests to receive 3,000 pages of documents from the Royal Canadian Mounted Police detailing the federal police agency's longstanding secret use of IMSI Catchers (AKA "Stingrays" -- the fake cellular towers that silently capture data on every cellphone user in range).

A group of researchers from Oxford and TU Berlin will present their paper, White-Stingray: Evaluating IMSI Catchers Detection Applications at the Usenix Workshop on Offensive Technologies, demonstrating countermeasures that Stingray vendors could use to beat Stingrays and other "cell-site simulators" (AKA IMSI catchers).

This summer, two of the west coast’s largest metropolitan areas—Seattle and California—took major steps to curtail secret, unilateral surveillance by local police. These victories for transparency and community control lend momentum toward sweeping reforms pending across California, as well as congressional efforts to curtail unchecked surveillance by federal authorities.

Well, there's a second-decade-of-the-21st-century headline for you! Read the rest

Rudy Carcamo-Carranza was an undocumented restaurant worker in Michigan wanted for a DUI and a hit-and-run; the FBI and ICE used IMSI catchers -- powerful, secretive cellphone tracking tools that the agencies bill as a kind of superweapon in the war on terror -- to catch him and put him up for deportation.

Companies in the EU and China have been caught offering to commit fraud to launder sales of mass surveillance weapons to Al Jazeera reporters posing as representatives of autocratic regimes under sanction for gross human rights abuses; these weapons would allow their users to target and round up political dissidents for arbitrary detention, torture and murder.

Police who rely on vulnerabilities in crooks' devices are terminally compromised; the best way to protect crime-victims is to publicize and repair defects in systems, but every time a hole is patched, the cops lose a tool they rely on the attack their own adversaries. Read the rest

Privacy International interviewed 57 sources for their report on the link between surveillance and torture and murder in Kenya, including 32 law enforcement, military or intelligence officers with direct firsthand knowledge of the programs. Read the rest

During the Standing Rock confrontations, the Electronic Frontier Foundation got reports of police use of IMSI Catchers -- secretive surveillance devices used to gather data from nearby cellphones, often called Stingrays or Dirtboxes -- so it dispatched lawyers and technologists to monitor the situation, and filed 20 public records requests with law enforcement agencies.

Muckrock has been sending Freedom of Information requests to state police forces to find out how they're using "cell-site simulators" (AKA IMSI catchers/Stingrays), and they hit the motherlode with the Virginia State Police. Read the rest

An outstanding post on the EFF's Deeplinks blog by my colleague Ernesto Falcon explains the negligent chain of events that led us into the Stingray disaster, where whole cities are being blanketed in continuous location surveillance, without warrants, public consultation, or due process, thanks to the prevalence of "IMSI catchers" ("Stingrays," "Dirtboxes," "cell-site simulators," etc) that spy indiscriminately on anyone carrying a cellular phone -- something the FCC had a duty to prevent.

The Intercept has got hold of a set of Harris's super-secretive manuals for their even-more-secret Stingray devices: fake cellular towers used to spy indiscriminately on whole populations by hacking their cellphones into giving up identifying information and more. Read the rest

The baseband firmware in your phone is the outermost layer of software, the "bare metal" code that has to be implicitly trusted by the phone's operating system and apps to work; a flaw in that firmware means that attackers can do scary things to your hone that the phone itself can't detect or defend against.

Stingrays -- the trade name for an "IMSI catcher," a fake cellphone tower that tricks cellphones into emitting their unique ID numbers and sometimes harvests SMSes, calls, and other data -- are the most controversial and secretive law-enforcement tools in modern American policing. Harris, the company that manufactures the devices, swears police departments to silence about their use, a situation that's led to cops lying to judges and even a federal raid on a Florida police department to steal stingray records before they could be introduced in open court.
