Submission + - Opening Fixed-Code Garage Doors With a Toy in 10 Seconds

Trailrunner7 writes: It may be time to upgrade your garage door opener. Security researcher Samy Kamkar has developed a new technique that enables him to open almost any garage door that uses a fixed code–and he implemented it on a $12 child’s toy.

The attack Kamkar devised, known as OpenSesame, reduces the amount of time it takes to guess the fixed code for a garage door from several minutes down to less than 10 seconds. Most openers in commercially available garage door openers have a set of 12 dip switches, which are binary, and provide a total of 4,096 possible code combinations. This is a highly limited keyspace and is open to brute-force attacks. But even on such a small keyspace, those attacks take some time.

With a simple brute-force attack, that would take 29 minutes, Kamkar said. To begin reducing that time, he eliminated the retransmission of each code, bringing the time down to about six minutes. He then removed the wait period after each code is sent, which reduced the time even further, to about three minutes. Looking to further reduce the time, Kamkar discovered that many garage door openers use a technique known as a bit shift register. This means that when the opener receives a 12-bit code, it will test that code, and if it’s incorrect, the opener will then shift out one bit and pull in one bit of the next code transmitted.

Kamkar implemented an algorithm known as the De Bruijn sequence to automate this process and then loaded his code onto a now-discontinued toy called the Mattel IM-ME. The toy was designed as a short-range texting device for kids, but Kamkar reprogrammed it using the GoodFET adapter built by Travis Goodspeed. Once that was done, Kamkar tested the device against a variety of garage door openers and discovered that the technique worked on systems manufactured by several companies, including Nortek and NSCD. It also works on older systems made by Chamberlain, Liftmaster, Stanley, Delta-3, and Moore-O-Matic.

When a device power circuit already integrate a voltage regulator, this is yet another battery scam.

We are just trying to describe and define it based on our consciousness and from what our senses can feel about it.
And given our consciousness and our senses are themselves artifacts of the universe. I think we will never be able to understand and describe outside of the thin domain of our own being.

Submission + - The Pentagon's $399 Billion Plane to Nowhere->

schwit1 writes: On July 3 the the entire F-35 Joint Strike Fighter fleet was being grounded after a June 23 runway fire.

The grounding could not have come at a worse time as costs have soared to an estimated $112 million per aircraft.

One thing the grounding won't do, however, is derail the F-35, a juggernaut of a program that apparently has enough political top cover to withstand any storm.

Part of that protection comes from the jaw-dropping amounts of money at stake. The Pentagon intends to spend roughly $399 billion to develop and buy 2,443 of the planes. However, over the course of the aircrafts' lifetimes, operating costs are expected to exceed $1 trillion. Lockheed has carefully hired suppliers and subcontractors in almost every state to ensure that virtually all senators and members of Congress have a stake in keeping the program — and the jobs it has created — in place.

"An upfront question with any program now is: How many congressional districts is it in?" said Thomas Christie, a former senior Pentagon acquisitions official.

Counting all of its suppliers and subcontractors, parts of the program are spread out across at least 45 states. That's why there's no doubt lawmakers will continue to fund the program even though this is the third time in 17 months that the entire fleet has been grounded due to engine problems.

It's a very good start but until they can manage dynamic clocking, proper monitoring of GPU, RAM and PCB temperature, and then adjust fan speeds or fallback lower in case of overheat, you are better be very careful with this recent feature.

Submission + - Selfie of Stroke Symptoms Finally Gets Woman Correct Diagnosis

theshowmecanuck writes: Canada's CBC TV reports that a woman suffering from a transient ischemic attack (mini-stroke) was diagnosed by the attending emergency room physician as suffering from stress, given tips on how to manage it and sent home. As she left the hospital she again began suffering the same symptoms in her car. Thinking quick she pulled out her smart phone and started taking a video selfie of herself to show the doctors the classic symptoms of a stroke. She was originally stricken at home and remembering the symptoms of a stroke from a public service announcement, went to the hospital when the symptoms subsided. After the second episode, her quick thinking and video convinced the doctors they were wrong and she was right, and they sent her for the proper diagnostic testing and treatment they should have given in first place. The article has a link to the video she took, but here it is in case, and I know it is unlikely on Slashdot, you don't want to read it.

Submission + - The upcoming Windows 8.1 apocalypse 2 2

arglebargle_xiv writes: As most people will have heard, Microsoft will end support for anyone who hasn't upgraded to Win8.1 Update 1 on May 8. What fewer people have heard is that large numbers of users can't install the 8.1 Update, with over a thousand messages in this one thread alone, and that's for tech geeks rather than home users who won't find out about this until their PC becomes orphaned on May 8. Check your Windows Update log, if you've got a "Failed" entry next to KB2919355 then your PC will also become orphaned after May 8.

Submission + - French journalist "hacks" govt by inputting correct URL, later fined $4,000+-> 1 1

mpicpp writes: In 2012, French blogger, activist, and businessman Olivier Laurelli sat down at his computer. It automatically connected to his VPN on boot (he owns a small security services company, called Toonux, which was providing a connection via a Panamanian IP address) and began surfing the Web.

Laurelli, who goes by the alias “Bluetouff” in most circles (including on Ars Technica), is something of a presence among the French tech-savvy community. Besides managing Toonux, he also co-founded the French-language activist news site Reflets.info, which describes itself as a “community project to connect journalists and computer networking specialists.” As such, Laurelli initiated a Google search on other subjects, but what he stumbled on was perhaps more interesting: a link that led to 7.7 Gb of internal documents from the French National Agency for Food Safety, Environment, and Labor (the acronym is ANSES in French).

Although the documents were openly indexed by Google, Laurelli would soon be in the French government’s crosshairs for publishing them. He eventually faced criminal charges, though he was later acquitted of those. However, a separate government agency pursued a civil appeal. And last Tuesday, a French appeals court fined Laurelli 3,000 Euros (or a little over $4,000), meaning he likely made one of the more expensive Google searches to date.

Submission + - Six Nissan Leaf Electric Cars Can Power an Office Building->

cartechboy writes: How many Nissan Leafs does it take to power an office building? The answer, it turns out, is six. Nissan is the latest Japanese automaker to explore electric "vehicle-to-building" setups, this time with impressive results. The company started testing its latest system at the Nissan Advanced Technology Center in Atsugi City, Japan, during the summer. It found that just six Leafs plugged in to the building's power supply allowed it to cut peak-hour electricity use by 2 percent. Annualized, that's a savings of half a million yen (about $4,800 US) in electricity costs. How it works: The building pulls electricity from the plugged-in vehicles during peak-use hours, when power is most expensive, and then sends the power back to recharge the cars when grid prices fall. Nissan says the system is set up to ensure the cars are fully charged by the end of the workday. (Is this a devious secret way to make sure workers stay until a certain time?) Next up: Why not just do this using batteries--never mind the cars?

"Figured this deserved its own thread. I hate to be the bearer of bad news here, but my previous statement that GK would be available on Linux turns out to be incorrect. I can't even begin to imagine why, but Activision isn't allowing the game to be made for that platform. Just PC, Mac, Android, and iOS devices."

Submission + - German summons US ambassador over NSA spying of Chancellor Angela Merkel

rtoz writes: German summons the US ambassador over claims that the US monitored German Chancellor Angela Merkel’s mobile phone.

Foreign minister Guido Westerwelle will personally meet US envoy John Emerson.

Previously, U.S President Barack Obama had denied the spying of German Chancellor Angela Merkel’s phone calls when she made call to Obama for asking about the reports of NSA spying of her phone calls.

And, Germany’s defense minister said that Europe can’t simply return to business as usual in its relations with Washington following allegations that U.S. intelligence may have targeted Chancellor Angela Merkel’s cellphone — though he stressed that ties will remain stable.

Defense Minister Thomas de Maiziere told ARD television the alleged surveillance would be “really bad” if confirmed. “The Americans are and remain our best friends, but this is absolutely not right,” he said.

Few days back, France called in the U.S. ambassador to protest at allegations in Le Monde newspaper about large-scale spying on French citizens by the U.S. National Security Agency (NSA).
