  • last year the company described a prototype solid state lithium superionic conductor battery in an article in the journal Nature Materials that was based on a three dimensional framework. And just this month the company announced plans to introduce several new lines of hybrid and all electric vehicles over the next three years (after also announcing that the Prius hybrid now accounts for ten percent of all sales). The sticking point has been and remains, the batteries used in such vehicles which can account for up to half their cost to consumers.
  • The new battery, first described last year, uses Li10GeP2S12 in a layered three dimensional framework where cells are sandwiched together to create a stack of seven tiers with each having a voltage of four volts for a total of twenty eight at normal temperatures. The result, they say is a battery with five times the output density of previous varieties. To demonstrate its progress in refining the battery, the prototype was demonstrated recently to a group attending a green technology seminar as a power source for an electric scooter.

    The Hummingbird's bird-shaped body is removable but it gives the bot an uncanny resemblance to a real hummingbird. The vehicle can hover and maneuver just like the bird. The ornithopter can fly into buildings under the control of an operator flying the spybot with the help of a feed from its tiny video camera. The prototype is capable of flying at speeds of up to 18 km/h (11 mph) and weighs 19 grams, which is about the same as an AA battery.

    The student team, Ori Ossmy, Ofir Tam and Ariel Rozen, developed the prototype application for their bachelor's degree project under the supervision BGU Prof. Mark Last, Dr. Rami Puzis, Prof. Yuval Lovitz and Dr. Lior Rokah. As part of a recent demonstration, a student composed and sent a hands-free e-mail using only thought combined with the adaptive hardware. The students and BGU team plan to continue research working with the disabled.

    BGU software engineering students have developed innovative technology that could enable people to operate a computer without using a keyboard or mouse - only their brainwaves. While there have been previous attempts to develop devices to read brainwaves and operate specific programs, they were cumbersome and not feasible outside of a laboratory setting. The BGU technology features a helmet equipped with 14 EEG connect points that sense brain activity. According to Dr. Rami Puzis, "The technology is designed to assist those who are physically disabled who might otherwise be unable to manipulate a computer mouse or keyboard." The student team, Ori Ossmy, Ofir Tam and Ariel Rozen, developed the prototype application for their bachelor's degree project under supervision at BGU by Prof. Mark Last, Dr. Rami Puzis, Prof. Yuval Elovich and Dr. Lior Rokah. As part of a recent demonstration, a student composed and sent a hands-free e-mail using only thought combined with the adaptive hardware. The students and BGU team plan to continue research working with the disabled.

  • Britain's surveillance agency GCHQ, with aid from the US National Security Agency, intercepted and stored the webcam images of millions of internet users not suspected of wrongdoing, secret documents reveal.
  • between 2008 and 2010
  • Optic Nerve, the documents provided by NSA whistleblower Edward Snowden show, began as a prototype in 2008 and was still active in 2012, according to an internal GCHQ wiki page accessed that year.The system, eerily reminiscent of the telescreens evoked in George Orwell's 1984, was used for experiments in automated facial recognition, to monitor GCHQ's existing targets, and to discover new targets of interest. Such searches could be used to try to find terror suspects or criminals making use of multiple, anonymous user IDs

  • Optic Nerve was based on collecting information from GCHQ's huge network of internet cable taps, which was then processed and fed into systems provided by the NSA. Webcam information was fed into NSA's XKeyscore search tool, and NSA research was used to build the tool which identified Yahoo's webcam traffic.

  • Since some time in the second half of 2014, a different state-sponsored group had been casing their corporate network using malware derived from Stuxnet, the highly sophisticated computer worm reportedly created by the US and Israel to sabotage Iran’s nuclear program.
  • the malware was more advanced than the malicious programs developed by the NSA-tied Equation Group that Kaspersky just exposed. More intriguing still, Kaspersky antivirus products showed the same malware has infected one or more venues that hosted recent diplomatic negotiations the US and five other countries have convened with Iran over its nuclear program.
  • We see this battle or arms race emerging and now it involves some kind of confrontation between the security industry and nation-state sponsored spies

  • Kaspersky officials first became suspicious their network might be infected in the weeks following February's Security Analyst Summit, where company researchers exposed a state-sponsored hacking operation that had ties to some of the developers of Stuxnet. Kaspersky dubbed the highly sophisticated group behind the 14-year campaign Equation Group. Now back in Moscow, a company engineer was testing a software prototype for detecting so-called advanced persistent threats (APTs), the type of well-organized and highly sophisticated attack campaigns launched by well-funded hacking groups. Strangely enough, the developer's computer itself was having unusual interactions with the Kaspersky network. The new APT technology under development, it seemed, was one of several things of interest to the Duqu attackers penetrating the Kaspersky fortress. "For the developer it was important to find out why" his PC was acting oddly, Kamluk said. "Of course, he did not consider that machine could be infected by real malware. We eventually found an alien module that should not be there that tried to mask behind legitimate looking modules from Microsoft. That was the point of discovery."
  • What they found was a vastly overhauled malware operation that made huge leaps in stealth, operational security, and software design. The Duqu actors also grew much more ambitious, infecting an estimated 100 or so targets, about twice as many as were hit by the 2011 version.
  • So the Duqu 2.0 attackers pulled an audacious feat that Kaspersky researchers had never seen before. Virtually all of the malware resided solely in the memory of the compromised computers or servers. When one of them was restarted, the infection would be purged, but as the rebooted machine reconnected to the network, it would be infected all over again by another compromised computer in the corporate network. The secret lynchpin making this untraceable reinfection scheme possible was the Windows vulnerability Microsoft patched only Tuesday, which has been designated
