Hyperloop—a theoretical, 760 mph transit system made of sun, air, and magnets

Concept sketches of the Hyperloop passenger capsules; note the air intake noses. Tesla Motors The proposed design for the “Hyperloop, ” an ultra-fast transit system that would run between San Francisco and Los Angeles, was revealed today on Elon Musk’s Tesla Motors website. Musk, the founder of SpaceX and Tesla Motors, describes a system that moves pods under low pressure through a tube between the two cities following the I-5 freeway, all within a 56-page PDF document . The Hyperloop would consist of aluminum pods inside a set of two steel tubes, one for each direction of travel. These are connected at each terminus. The tubes would be positioned on top of pylons spaced 100 feet apart holding the tube 20 feet in the air, and the tube would be covered by solar arrays to generate its own power. Inside the tubes, the pods would carry people up to 760 miles per hour. The pods would each carry 28 passengers, departing every two minutes from either location (or every 30 seconds at peak times). So each pod would have about 23 miles between each other while traversing the tube. The transport capacity would therefore be about 840 passengers per hour.

FBI director calls on private sector to man up, help with cyber threat

Robert Mueller, FBI Director, says Keith and John are his BFFs. FBI FBI Director Robert S. Mueller, CIA Director John Brennan, and National Security Agency (NSA) Director Gen. Keith Alexander shared the stage on August 8 at the International Conference on Cyber Security  (ICCS), an event cohosted by the FBI and Fordham University in New York. The three spoke on a panel about the future of cybersecurity. Mueller spoke about the Lulzec case and how the FBI caught Hector “Sabu” Monsegur , along with how it will deal with increasingly sophisticated hackers and cybercriminals. Key to the bureau’s success, he said, was “focusing on the individuals behind the keyboards”—with the help of the NSA, CIA, and private industry. “I do believe that in the future, the cyber threat will equal or even eclipse the terrorist threat, ” Mueller said in his opening remarks. “And just as partnerships have enabled us to address the terrorist threat, partnerships will enable us to address the cyber threat. But the array of partners critical to defeating the cyber threat is different. In this case, the private sector is the essential partner.” Getting into hackers’ heads “In the years to come, we will encounter new intrusion methods, hacking techniques, and other unpleasant surprises, ” Mueller said in his prepared remarks for the panel. “And in response, our nation will continue to develop—as we must—the technical skills and tools to prevent these intrusions and limit their damage.” Read 8 remaining paragraphs | Comments

“Hand of Thief” banking trojan doesn’t do Windows—but it does Linux

The administration panel for Hand of Thief. RSA Signaling criminals’ growing interest in attacking non-Windows computers, researchers have discovered banking fraud malware that targets people using the open-source Linux operating system. Hand of Thief, as researchers from security firm RSA have dubbed it , sells for about $2, 000 in underground Internet forums and boasts its own support and sales agents. Its functionality—consisting of form grabbers and backdoor capabilities—is rudimentary compared to Windows banking trojans spawned from the Citadel or Blackhole exploit kits, but that’s likely to change. RSA researcher Limor Kessem said she expects Hand of Thief to become a full-blown banking trojan that includes more advanced features such as the ability to inject attacker-controlled content into trusted bank webpages. “Although Hand of Thief comes to the underground at a time when commercial trojans are high in demand, writing malware for the Linux OS is uncommon, and for good reason, ” Kessem wrote. “In comparison to Windows, Linux’s user base is smaller, considerably reducing the number of potential victims and thereby the potential fraud gains.” Read 5 remaining paragraphs | Comments

Mobile startup offers unprecedented plan: 500MB of data, free incoming calls

On Tuesday, the American mobile phone market took one step closer to looking a bit more like the European or Asian markets: free incoming calls, inexpensive outgoing calls, and a focus on data. A Canadian startup, TextNow , just launched a new mobile service in the United States. For $18.99 per month, you get 500MB of data, 750 rollover minutes, and unlimited texting and incoming calls. In the US, it’s the norm for both the sending and receiving parties to be charged for a call. But nearly everywhere else in the world, only the person who originated the call actually pays. “Incoming calls don’t really cost us that much, ” Derek Ting, the company’s CEO, told Ars. “Carriers charge you anyway because they can get away with it.” Read 5 remaining paragraphs | Comments

Update: Researchers say Tor-targeted malware phoned home to NSA

A search reveals the address used in an attack on Tor users’ privacy referenced an IP address belonging to the NSA, routed through SAIC. Malware planted on the servers of Freedom Hosting — the “hidden service” hosting provider on the Tor anonymized network brought down late last week—may have de-anonymized visitors to the sites running on that service. This issue could send identifying information about site visitors to an Internet Protocol address that was hard-coded into the script the malware injected into browsers. And it appears the IP address in question belongs to the National Security Agency (NSA). This revelation comes from analysis done collaboratively by Baneki Privacy Labs , a collective of Internet security researchers, and VPN provider Cryptocloud . When the IP address was uncovered in the JavaScript exploit —which specifically targets Firefox Long-Term Support version 17, the version included in Tor Browser Bundle—a source at Baneki told Ars that he and others reached out to the malware and security community to help identify the source. The exploit attacked a vulnerability in the Windows version of the Firefox Extended Support Release  17 browser —the one used previously in the Tor Project’s Tor Browser Bundle (TBB).  That vulnerability had been patched by Mozilla in June, and the updated browser is now part of TBB. But the TBB configuration of Firefox doesn’t include automatic security updates, so users of the bundle would not have been protected if they had not recently upgraded.

Simple technique puts graphene capacitors on par with lead-acid battery

If the bottom is a layer of graphene in a super capacitor, then storage can be increased by making the solution above it as low-volume as possible. Lawrence Livermore National Lab Individual pieces of graphene have some pretty amazing properties, but finding a way to produce bulk materials that make good use of those properties has been rather challenging. Now, researchers have figured out a way to make graphene-based electrodes in bulk through a process so simple that it can be adapted to the manufacturing techniques that we currently use to make paper. And the resulting capacitors, at least in these test cases, had storage capacities that approached those of lead-acid batteries. Those of us who have taken basic physics tend to think of capacitors as two parallel, charge-holding plates, since that’s how they’re taught. But electrochemical capacitors perform a similar trick on a much smaller scale, by having the charges held by individual ions that absorb to an electrode. To boost capacity, the simplest thing to do is to increase the surface area for the ions to interact with. That’s why graphene seems so appealing; since it’s only a single atom thick, it should be possible to stick a tremendous amount of surface into a relatively small volume. The problem, however, has been getting the ions into the graphene itself in order for them to interact. Once the graphene is prepared, lots of factors like pore size and inter-sheet spacing come into play, since these control how quickly ions can get into the graphene. A team at Australia’s Monash University came up with an easy solution to this: put the ions in place during the manufacturing process. Read 4 remaining paragraphs | Comments

Alleged Tor hidden service operator busted for child porn distribution

Catherine Scott On Friday, Eric Eoin Marques, a 28 year-old Dublin resident, was arrested on a warrant from the US on charges that he is, in the words of a FBI agent to an Irish court , “the largest facilitator of child porn on the planet.” The arrest coincides with the disappearance of a vast number of ” hidden services ” hosted on Tor, the anonymizing encrypted network. Marques is alleged to be the founder of Freedom Hosting, a major hidden services hosting provider. While Marques’ connection to Freedom Hosting was not brought up in court, he has been widely connected to the service—as well as the Tormail anonymized e-mail service and a Bitcoin exchange and escrow service called Onionbank—in discussions on Tor-based news and Wiki sites. All those services are now offline. And prior to disappearing, the sites hosted by Freedom Hosting were also distributing malware that may have been used to expose the users of those services. Tor hidden services are a lesser known part of the Tor “darknet.” They are anonymized Web sites, mail hosts, and other services which can only be reached by computers connected to Tor, or through a Tor hidden services proxy website, such as tor2web.org , and they have host names ending in .onion.

SkyDrive follows Metro into oblivion as Microsoft abandons trademark case

“How’s SkyDrive?” “Oh, SkyDrive… won’t see him no more.” Microsoft One month after a British court ruled that Microsoft’s SkyDrive infringed on a British Sky Broadcasting (BSkyB) Group trademark, Microsoft has decided not to appeal and will find a new name for its cloud storage service. A press release Microsoft provided to Ars today states that BSkyB and Microsoft have agreed to a “settlement of trade mark infringement proceedings in the European Union brought by Sky against Microsoft in the English High Court… According to the settlement, Microsoft will not pursue its planned appeal of this decision and Sky will allow Microsoft to continue using the SkyDrive name for a reasonable period of time to allow for an orderly transition to a new brand. The agreement also contains financial and other terms, the details of which are confidential.” Microsoft said it would not provide any details beyond what’s in the press release, which also makes a vague reference to “joint projects” to benefit Microsoft and BSkyB customers. A new name for SkyDrive was not announced. The release does not specify whether the name change would occur in Europe only or worldwide, but it seems likely that Microsoft would want to have one name for the service in every region.

Trusting iPhones plugged into bogus chargers get a dose of malware

The Mactans charger uses a BeagleBoard for its computational power. Billy Lau, Yeongjin Jang, and Chengyu Song Plugging your phone into a charger should be pretty safe to do. It should fill your phone with electricity, not malware. But researchers from Georgia Institute of Technology have produced fake chargers they’ve named Mactans that do more than just charge your phone: they install custom, malicious applications onto iPhones. Their bogus chargers—which do, incidentally, charge the phone—contain small computers instead of mere transformers. The iPhone treats these computers just as it does any other computer; instead of just charging, it responds to USB commands. It turns out that the iPhone is very trusting of USB-attached computers; as long as the iPhone is unlocked (if only for a split second) while attached to a USB host, then the host has considerable control over the iPhone. The researchers used their USB host to install an app package onto any iPhone that gets plugged in. iOS guards against installation of arbitrary applications with a strict sandboxing system, a feature that has led to the widespread practice of jailbreaking. This attack doesn’t need to jailbreak, however. Read 6 remaining paragraphs | Comments

Thailand bans using Bitcoin in any way, local startup reports

A Bitcoin startup based in Thailand now says that it has suspended all operations  because the Bank of Thailand has effectively banned bitcoins in the southeast Asian country. As Bitcoin Co. Ltd. reports: At the conclusion of the meeting, senior members of the Foreign Exchange Administration and Policy Department advised that due to lack of existing applicable laws, capital controls, and the fact that Bitcoin straddles multiple financial facets the following Bitcoin activities are illegal in Thailand: – Buying bitcoins – Selling bitcoins – Buying any goods or services in exchange for bitcoins – Selling any goods or services for bitcoins – Sending bitcoins to anyone located outside of Thailand – Receiving bitcoins from anyone located outside of Thailand This appears to be the first time that any country has outright banned the digital crypto currency . Further, it remains unclear exactly how Thailand would even enforce such a ban. Ars has been unable to confirm the ban with the Bank of Thailand , when this ban goes into effect, and how this decision came about. Bank representatives did not immediately respond to Ars’ request for comment. Read 1 remaining paragraphs | Comments
