This crowdfunded router updates its own security

It’s really, really, really hard to make a router sound exciting , but the folks behind the Turris Omnia are betting the device’s focus on keeping your sensitive data secure might grab you. The manufacturer’s IndieGogo campaign still has 45 days to go, but it’s already proved incredibly popular: over a thousand backers have pledged some $274, 598 as of this writing. That’s 275 percent higher than the threshold for funding the project. The router itself runs Turris’ open source operating system (based on the OpenWRT project ) which auto updates as soon as any type of vulnerability is discovered by its cadre of developers.

DecryptorMax/CryptInfinite Ransomware Decrypted, No Need To Pay Ransom

An anonymous reader writes: Emsisoft has launched a new tool capable of decrypting files compromised by the DecryptorMax (CryptInfinite) ransomware. The tool is quite easy to use, and will generate a decryption key. For best results users should compare an encrypted and decrypted file, but the tool can also get the decryption key by comparing an encrypted PNG with a random PNG downloaded off the Internet.

Scientists Produce Graphene 100 Times Cheaper Than Ever Before

Zothecula writes that researchers at the University of Glasgow have found a way to produce large sheets of graphene 100 times more cheaply than previous methods. Gizmag reports: “Since first being synthesized by Andre Geim and Kostya Novoselov at the University of Manchester in 2004, there has been an extensive effort to exploit the extraordinary properties of graphene. However the cost of graphene in comparison to more traditional electronic materials has meant that its uptake in electronic manufacturing has been slow. Now researchers at the University of Glasgow have discovered a way to create large sheets of graphene using the same type of cheap copper used to manufacture lithium-ion batteries.” Read more of this story at Slashdot.

Even the Dumbest Ransomware Is Almost Unremovable On Smart TVs

An anonymous reader writes: Apparently even the easiest-to-remove ransomware is painfully hard to uninstall from smart TVs, if they’re running on the Android TV platform, and many are. This didn’t happen in a real-world scenario (yet), and was only a PoC test by Symantec. The researcher managed to remove the ransomware only because he enabled the Android ADB tool beforehand, knowing he would infect the TV with the ransomware. “Without this option enabled, and if I was less experienced user, I’d probably still be locked out of my smart TV, making it a large and expensive paper weight, ” said the researcher.

Understanding the Antikythera Mechanism

szczys writes: We attribute great thinking to ancient Greece. This is exemplified by the Antikythera Mechanism. Fragments of the mechanism were found in a shipwreck first discovered in 1900 and visited by researchers several times over the next century. It is believed to be a method of tracking the calendar and is the first known example of what are now common-yet-complicated engineering mechanisms like the differential gear. A few working reproductions have been produced and make it clear that whomever designed this had an advanced understanding of complex gear ratios and their ability to track the passage of time and celestial bodies. Last year research by two scientists suggested that the device might be much older than previously thought. Read more of this story at Slashdot.

TrueCrypt Safer Than Previously Thought

An anonymous reader writes: Back in September, members of Google’s Project Zero team found a pair of flaws in the TrueCrypt disk encryption software that could lead to a system compromise. Their discovery raised concerns that TrueCrypt was unsuitable for use in securing sensitive data. However, the Fraunhofer Institute went ahead with a full audit of TrueCrypt’s code, and they found it to be more secure than most people think. They correctly point out that for an attacker to exploit the earlier vulnerabilities (and a couple more vulnerabilities they found themselves), the attacker would already need to have “far-reaching access to the system, ” with which they could do far worse things than exploit an obscure vulnerability. The auditors say, “It does not seem apparent to many people that TrueCrypt is inherently not suitable to protect encrypted data against attackers who can repeatedly access the running system. This is because when a TrueCrypt volume is mounted its data is generally accessible through the file system, and with repeated access one can install key loggers etc. to get hold of the key material in many situations. Only when unmounted, and no key is kept in memory, can a TrueCrypt volume really be secure.” For other uses, the software “does what it’s designed for, ” despite its code flaws. Their detailed, 77-page report (PDF) goes into further detail. Read more of this story at Slashdot.

Researchers Create Plant-Circuit Hybrid

sciencehabit writes: Researchers have crafted flexible electronic circuits inside a rose. Eventually such circuitry may help farmers eavesdrop on their crops and even control when they ripen. The advance may even allow people to harness energy from trees and shrubs not by cutting them down and using them for fuel, but by plugging directly into their photosynthesis machinery. The researchers used “an organic electronic building block called PEDOT-S:H. Each of these building blocks consists of a short, repeating chain of a conductive organic molecule with short arms coming off each link of the chain. Each of the arms sports a sulfur-containing group linked to a hydrogen atom. Berggren’s group found that when they placed them in the water, the rose stems readily pulled the short polymer chains up the xylem channels (abstract). … The upshot was that the myriad short polymer chains quickly linked themselves together into continuous strings as long as 10 centimeters. The researchers then added electronic probes to opposite ends of these strings, and found that they were, in fact, wires, conducting electricity all down the line.” Read more of this story at Slashdot.

Sony Quietly Adds PS2 Emulation To the PS4

An anonymous reader writes: The Digital Foundry blog reports that Sony has added functionality to the PlayStation 4 that allows it to act as an emulator for some PlayStation 2 games. Surprisingly, the company did not mention that this functionality is live; a new Star Wars game bundle just happened to include three titles that were released on the PS2. From the article: “How can we tell? First of all, a system prompt appears telling you that select and start buttons are mapped to the left and right sides of the Dual Shock 4’s trackpad. Third party game developers cannot access the system OS in this manner. Secondly, just like the PS2 emulator on PlayStation 3, there’s an emulation system in place for handling PS2 memory cards. Thirdly, the classic PlayStation 2 logo appears in all of its poorly upscaled glory when you boot each title.” Sony has confirmed the games are being emulated, but declined to provide any further details.

First Liquid-Cooling Laser Could Advance Biological Research

Zothecula writes: In a world where lasers are sci-fi’s weapon of choice for melting away an enemy spaceship, researchers at the University of Washington have swum against the current and produced the first laser capable of cooling liquids. ” They demonstrated that the laser could refrigerate saline solution and cell culture media that are commonly used in genetic and molecular research. To achieve the breakthrough, the UW team used a material commonly found in commercial lasers but essentially ran the laser phenomenon in reverse. They illuminated a single microscopic crystal suspended in water with infrared laser light to excite a unique kind of glow that has slightly more energy than that amount of light absorbed. This higher-energy glow carries heat away from both the crystal and the water surrounding it.” The technology could be especially useful for slowing down single cells and allowing scientists to study biological processes as they happen.

US Navy Is Planning To Launch a Squadron of Underwater Drones By 2020

Hallie Siegel writes: According to the non-profit Autonomous Undersea Vehicle Applications Center, there are over 250 different configurations of unmanned undersea vehicles (UUVs) in service today. That number is likely to grow in the coming years as the technology improves — note that the US Navy has made UUVs a priority and is planning to launch a whole squadron of them by 2020. Dan Gettinger from the Center for the Study of the Drone at Bard College gives an overview of this technology. Read more of this story at Slashdot.
