New App Detects Government Stingray Cell Phone Trackers 71

HughPickens.com writes IMSI catchers, otherwise known as stingrays, are those surveillance tools that masquerade as cell towers and trick mobile phones into connecting, spewing private data in the process. Law-enforcement agencies have been using them for almost two decades, but there's never been a good way for individuals to detect them. Now Lily Hay Newman reports that SnoopSnitch scans for radio signals that indicate a transition to a stingray from a legitimate cell tower. "SnoopSnitch collects and analyzes mobile radio data to make you aware of your mobile network security and to warn you about threats like fake base stations (IMSI catchers), user tracking and over-the-air updates." say German security researchers Alex Senier, Karsten Nohl, and Tobias Engel, creators of the app which is available now only for Android. The app can't protect people's phones from connecting to stingrays in the first place, but it can at least let them know that there is surveillance happening in a given area. "There's no one set of information, taken by itself, that allows you to detect an IMSI catcher," says Nohl. "But we do stream analysis of everything that happens on your phone, and can come out with a warning if it crosses a certain threshold."

Stingrays have garnered attention since a 2011 Arizona court case in which one agent admitted in an affidavit that the tool collaterally swept up data on "innocent, non-target devices" (U.S. v. Rigmaiden). The government eventually conceded in this case that the "tracking operation was a Fourth Amendment search and seizure," meaning it required a warrant. But given that the Justice Department has continued to claim that cellphone users have no reasonable expectation of privacy over their location data, it may take a Supreme Court judgement to settle the Stingray issue countrywide.

Being Colder May Be Good For Your Health 234

An anonymous reader writes: If you live in a developed nation, you're probably pretty warm throughout most of the day. Enclosed spaces, thick clothing, and heating devices do a good job to keep the cold away. But this hasn't been the case for most of human history. Even in warmer climates, humans often had to deal with chilly nights and tough winters. That's where our metabolic system evolved, and now people are doing research to figure out if that's a better natural state for maintaining our health.

One recent study found that "when people cool their bedrooms from 75 degrees to 66 degrees, they gain brown fat, the metabolically active fat that burns calories to generate heat." Another showed that "even after controlling for diet, lifestyle, and other factors, people who live in warmer parts of Spain are more likely to be obese than people who live in the cooler parts." The article talks about people letting their house temperatures drop into the 50s and wearing ice vests during the day, all in the name of further research.

Paul Graham: Let the Other 95% of Great Programmers In 552

An anonymous reader writes: Y Combinator's Paul Graham has posted an essay arguing in favor of relaxed immigration rules. His argument is straight-forward: with only 5% of the world's population, the U.S. can only expect about 5% of great programmers to be born here. He says, "What the anti-immigration people don't understand is that there is a huge variation in ability between competent programmers and exceptional ones, and while you can train people to be competent, you can't train them to be exceptional. Exceptional programmers have an aptitude for and interest in programming that is not merely the product of training."

Graham says even a dramatic boost to the training of programmers within the U.S. can't hope to match the resources available elsewhere. "We have the potential to ensure that the U.S. remains a technology superpower just by letting in a few thousand great programmers a year. What a colossal mistake it would be to let that opportunity slip. It could easily be the defining mistake this generation of American politicians later become famous for."

Chromebook Gets "OK Google" and Intel's Easy Migration App 35

An anonymous reader points out that Chromebook users just got a couple of early gifts. "Chromebooks have had a good run thus far in their history, and most recently they've had a stellar year of sales – famously beating out Apple's iPad. However, Google is not stopping there, as the company has decided to include and integrate 'OK Google' into their Chromebook tablets. As it turns out, the feature was possible all along with the code that had been included in the operating system, but was hidden well from users' direct line of sight. Intel has also shown a lot of support for Chromebooks, and the company has now released the Easy Migration app that will fittingly migrate data between Windows devices, iOS devices, and Android devices. The only catch is that users will have to be running a Chromebook that hosts an Intel processor. Intel has provided a website to check if your device is compatible, but it will surely be a significant hit for the Chromebook."

Over 9,000 PCs In Australia Infected By TorrentLocker Ransomware 83

First time accepted submitter River Tam writes Cybercriminals behind the TorrenLocker malware may have earned as much as $585,000 over several months from 39,000 PC infections worldwide, of which over 9,000 were from Australia. If you're a Windows user in Australia who's had their files encrypted by hackers after visiting a bogus Australia Post website, chances are you were infected by TorrentLocker and may have contributed to the tens of thousands of dollars likely to have come from Australia due to this digital shakedown racket.

$35 Quad-core Hacker SBC Offers Raspberry Pi-like Size and I/O 140

DeviceGuru writes: Hardkernel has again set its sights on the Raspberry Pi with a new $35 Odroid-C1 hacker board that matches the RPI's board size and offers a mostly similar 40-pin expansion connector. Unlike the previous $30 Odroid-W that used the same Broadcom BCM2835 SoC as the Pi and was soon cancelled due to lack of BCM2835 SoC availability, the Odroid-C1 is based on a quad-core 1.5GHz Cortex-A5 based Amlogic S805 SoC, which integrates the Mali-400 GPU found on Allwinner's popular SoCs. Touted advantages over the similarly priced Raspberry Pi Model B+ include a substantially more powerful processor, double the RAM, an extra USB2.0 port that adds Device/OTG, and GbE rather than 10/100 Ethernet.

POODLE Flaw Returns, This Time Hitting TLS Protocol 54

angry tapir writes: If you patched your sites against a serious SSL flaw discovered in October you will have to check them again. Researchers have discovered that the POODLE vulnerability also affects implementations of the newer TLS protocol. The POODLE (Padding Oracle On Downgraded Legacy Encryption) vulnerability allows attackers who manage to intercept traffic between a user's browser and an HTTPS website to decrypt sensitive information, like the user's authentication cookies.

How the Rollout of 5G Will Change Everything 216

mrspoonsi writes The global race is on to develop 5G, the fifth generation of mobile network. While 5G will follow in the footsteps of 4G and 3G, this time scientists are more excited. They say 5G will be different — very different. "5G will be a dramatic overhaul and harmonization of the radio spectrum," says Prof Rahim Tafazolli who is the lead at the UK's multimillion-pound government-funded 5G Innovation Centre at the University of Surrey. To pave the way for 5G the ITU is comprehensively restructuring the parts of the radio network used to transmit data, while allowing pre-existing communications, including 4G and 3G, to continue functioning. 5G will also run faster, a lot faster. Prof Tafazolli now believes it is possible to run a wireless data connection at an astounding 800Gbps — that's 100 times faster than current 5G testing. A speed of 800Gbps would equate to downloading 33 HD films — in a single second. Samsung hopes to launch a temporary trial 5G network in time for 2018's Winter Olympic Games.

Clarificiation on the IP Address Security in Dropbox Case 152

Bennett Haselton writes A judge rules that a county has to turn over the IP addresses that were used to access a county mayor's Dropbox account, stating that there is no valid security-related reason why the IP addresses should be exempt from a public records request. I think the judge's conclusion about IP addresses was right, but the reasoning was flawed; here is a technically more correct argument that would have led to the same answer. Keep Reading to see what Bennett has to say about the case.

Is Ruby On Rails Losing Steam? 291

itwbennett writes: In a post last week, Quartz ranked the most valuable programming skills, based on job listing data from Burning Glass and the Brookings Institution. Ruby on Rails came out on top, with an average salary of $109,460. And that may have been true in the first quarter of 2013 when the data was collected, but "before you run out and buy Ruby on Rails for Dummies, you might want to consider some other data which indicate that Rails (and Ruby) usage is not trending upwards," writes Phil Johnson. He looked at recent trends in the usage of Ruby (as a proxy for Rails usage) across MS Gooroo, the TIOBE index, the PYPL index, Redmonk's language rankings, and GitHut and found that "demand by U.S. employers for engineers with Rails skills has been on the decline, at least for the last year."

People Trained To Experience an Overlap In Senses Also Receive IQ Boost 68

Zothecula writes Tasting lemons when they see a number seven, regarding a certain letter as being yellow in color. Not a great deal is known about why some people experience an overlapping of the senses, a phenomena known as synesthesia. But a new study conducted at the University of Sussex has suggested that specific training of the mind can induce the effects of the condition. The study even suggests that such training can boost a person's IQ.

Joey Hess Resigns From Debian 450

An anonymous reader writes: Long-time Debian developer Joey Hess has posted a resignation letter to the Debian mailing list. Hess was a big part of the development of the Debian installer, debhelper, Alien, and other systems. He says, "It's become abundantly clear that this is no longer the project I originally joined in 1996. We've made some good things, and I wish everyone well, but I'm out. ... If I have one regret from my 18 years in Debian, it's that when the Debian constitution was originally proposed, despite seeing it as dubious, I neglected to speak out against it. It's clear to me now that it's a toxic document, that has slowly but surely led Debian in very unhealthy directions."

Independent Researchers Test Rossi's Alleged Cold Fusion Device For 32 Days 986

WheezyJoe (1168567) writes The E-Cat (or "Energy Catalyzer") is an alleged cold fusion device that produces heat from a low-energy nuclear reaction where nickel and hydrogen fuse into copper. Previous reports have tended to suggest the technology is a hoax, and the inventor Andrea Rossi's reluctance to share details of the device haven't helped the situation. ExtremeTech now reports that "six (reputable) researchers from Italy and Sweden" have "observed a small E-Cat over 32 days, where it produced net energy of 1.5 megawatt-hours, "far more than can be obtained from any known chemical sources in the small reactor volume."... "The researchers, analyzing the fuel before and after the 32-day burn, note that there is an isotope shift from a "natural" mix of Nickel-58/Nickel-60 to almost entirely Nickel-62 — a reaction that, the researchers say, cannot occur without nuclear reactions (i.e. fusion)." The paper (PDF) linked in the article concludes that the E-cat is "a device giving heat energy compatible with nuclear transformations, but it operates at low energy and gives neither nuclear radioactive waste nor emits radiation. From basic general knowledge in nuclear physics this should not be possible. Nevertheless we have to relate to the fact that the experimental results from our test show heat production beyond chemical burning, and that the E-Cat fuel undergoes nuclear transformations. It is certainly most unsatisfying that these results so far have no convincing theoretical explanation, but the experimental results cannot be dismissed or ignored just because of lack of theoretical understanding. Moreover, the E-Cat results are too conspicuous not to be followed up in detail. In addition, if proven sustainable in further tests the E-Cat invention has a large potential to become an important energy source." The observers understandably hedge a bit, though: The researchers are very careful about not actually saying that cold fusion/LENR is the source of the E-Cat’s energy, instead merely saying that an “unknown reaction” is at work. In serious scientific circles, LENR is still a bit of a joke/taboo topic. The paper is actually somewhat comical in this regard: The researchers really try to work out how the E-Cat produces so much darn energy — and they conclude that fusion is the only answer — but then they reel it all back in by adding: “The reaction speculation above should only be considered as an example of reasoning and not a serious conjecture.”

Four Dutch Uberpop Taxi Drivers Arrested, Fined 282

An anonymous reader writes with news that authorities in the Netherlands have arrested four drivers sharing their car for money through the Uberpop app. The drivers were then released with a fine of EUR 4,200 (USD 5,300) each and further threatened with additional fines of EUR 10,000 (USD 12,600) for each time they might be caught doing it again. While similar bullying applied to short rentals of private rooms through sites like Airbnb hasn't had the same success so far the thoughts go to the fined drivers, hoping they won't ever be caught carrying their grandmother to the supermarket then have to explain how they dared. Uber says it will "fully support" the affected drivers."

Smart Gun Inspires Smart Mouse Authentification System 60

dcblogs writes Defense contractor Raytheon has received a patent for a mouse that has a biometric pressure grip. It believes the pressure grip, as a form of authentication, will be particularly hard to defeat because it works from a neurological pattern versus a physical pattern, such as a facial scan. "It's not just how much pressure you exert on the mouse itself, but it's also the x-y coordinates of your position," said Glenn Kaufman, a cybersecurity engineer. The approach was inspired by similar pressure grips used in smart guns.
