concealment writes with news that a court battle has brought to light details on how the FBI’s “stingray” surveillance tool works, and how they used it with Verizon’s help to collect evidence about an alleged identity thief. Quoting: “Air cards are devices that plug into a computer and use the wireless cellular networks of phone providers to connect the computer to the internet. The devices are not phones and therefore don’t have the ability to receive incoming calls, but in this case Rigmaiden asserts that Verizon reconfigured his air card to respond to surreptitious voice calls from a landline controlled by the FBI. The FBI calls, which contacted the air card silently in the background, operated as pings to force the air card into revealing its location. In order to do this, Verizon reprogrammed the device so that when an incoming voice call arrived, the card would disconnect from any legitimate cell tower to which it was already connected, and send real-time cell-site location data to Verizon, which forwarded the data to the FBI. This allowed the FBI to position its stingray in the neighborhood where Rigmaiden resided. The stingray then “broadcast a very strong signal” to force the air card into connecting to it, instead of reconnecting to a legitimate cell tower, so that agents could then triangulate signals coming from the air card and zoom-in on Rigmaiden’s location. To make sure the air card connected to the FBI’s simulator, Rigmaiden says that Verizon altered his air card’s Preferred Roaming List so that it would accept the FBI’s stingray as a legitimate cell site and not a rogue site, and also changed a data table on the air card designating the priority of cell sites so that the FBI’s fake site was at the top of the list.” Read more of this story at Slashdot.

paysonwelch writes “North Korea has declared a state of war against South Korea, stating that neither peace nor war has ended. Quoting the news release via Reuters: ‘1. From this moment, the north-south relations will be put at the state of war and all the issues arousing between the north and the south will be dealt with according to the wartime regulations.’ The DPRK goes on to say that this will be a ‘blitz’ war and that they will regain control of the south, and destroy U.S. bases in the process.” Great line from the declaration: “[The U.S.] should clearly know that in the era of Marshal Kim Jong Un, the greatest-ever commander, all things are different from what they used to be in the past.” A senior U.S. official called this statement “pot-banging and chest-thumping.” The official said, “North Korea is in a mindset of war, but North Korea is not going to war.” Read more of this story at Slashdot. 
Wired reports that the 3-D printed AR-15 magazine from Defense Distributed we mentioned a few weeks back has been improved through design, and is now robust enough to last through firing (at least) several hundred rounds, rather than fewer than a hundred as in the previous iteration. CNET says the video demonstration on YouTube was first yanked, then restored, but as of now seems to have been yanked again. Read more of this story at Slashdot. 
According to the Daily Yomiuri, “Japan launched two satellites on Jan. 27 to strengthen its surveillance capabilities, including keeping a closer eye on North Korea which has vowed to stage another nuclear test. One of them was a radar-equipped unit to complete a system of surveillance satellites that will allow Tokyo to monitor any place in the world at least once a day. The other was a demonstration satellite to collect data for research and development.” The Defense News version of the story says “Japan developed a plan to use several satellites as one group to gather intelligence in the late 1990s as a response to a long-range missile launch by Pyongyang in 1998. The space agency has said the radar satellite would be used for information-gathering, including data following Japan’s 2011 quake and tsunami, but did not mention North Korea by name.” Read more of this story at Slashdot.
