Microsoft today announced plans to open source .NET, the company’s software
framework that primarily runs on Windows, and release it on GitHub. Microsoft
also unveiled plans to take .NET cross-platform by targeting both Mac OS X and
Linux.
In the next release, Microsoft plans to open source the entire .NET server
stack, from ASP.NET 5 down to the Common Language Runtime and Base Class
Libraries. The company will let developers build .NET cloud applications on
multiple platforms; it is promising future support of the .NET Core server
runtime and framework for Mac and Linux.

New Research Shows Vulnerability in Mobile Phones' Applications Offering Voice Communication Security
UAB News (11/05/14) Katherine Shonesy
Researchers at the University of Alabama at Birmingham (UAB) are studying the security vulnerabilities of video- and voice-over-Internet Protocol communications. The researchers developed attacks that uncovered vulnerabilities in a currently used security scheme, and once those weaknesses were identified, the team suggested alternatives that may protect against potential attacks, focusing on a peer-to-peer mechanism known as Crypto Phones. Crypto Phones is a security measure claiming to completely address the problem of wiretapping, in which users orally exchange information resulting from a cryptographic protocol employing Short Authenticated Strings to confirm each other's identity. The researchers found this security tool is vulnerable to automated voice mimicry attacks. One potential defense to these attacks could be the integration of an automated voice recognition or voice biometrics system into Crypto Phones, according to the researchers. "The results bring to light the threats of conceived voice privacy, and should serve as notice to users to pay careful attention to the potential security weaknesses in the future," says UAB Ph.D. student and project leader Maliheh Shirvanian. The researchers presented their findings this week at the 21st ACM Conference on Computer and Communications Security in Scottsdale, AZ.

Computers Could Talk Themselves Into Giving Up Secrets
Technology Review (10/30/14) David Talbot
Researchers from the Georgia Institute of Technology say they have found numerous security flaws that could allow malicious hackers to seize control of PCs and smartphones through the use of voice-control features, including those designed to make the devices easier for disabled individuals to use. In research that will be presented at the 21st ACM Conference on Computer and Communications Security this week in Scottsdale, AZ, the researchers describe 12 methods of subverting devices running the Android, iOS, Windows, or Ubuntu Linux operating systems (OSes), in some cases using methods that would not require any physical contact with the device. One attack uses malware that leverages Windows Speech Recognition to talk its way into running commands that would normally require a higher level of privilege, while another involves subverting the voiceprint feature of Android's Google Now digital assistant to access a device and then using generic text-to-speech apps to issue commands as if it were the user. Lead researcher Wenke Lee says most of the vulnerabilities are the result of voice command features being added late in the development cycle, making them less likely to be vetted for security vulnerabilities. "These features were added after the OS had been implemented, so these features don't have the same kinds of security checks," Lee says.

Computer Game Could Help Visually-Impaired Children Live Independently
University of Lincoln (10/31/14) Cerri Evans
University of Lincoln researchers are developing Eyelander, a computer game they say could help visually-impaired children lead independent lives. The game focuses on improving the functional vision of children who have sight issues due to a brain injury rather than damage to the eye itself. "We are tapping into the brain's innate ability to adapt (also known as neuroplasticity), and because substantial changes in vision are possible even into adulthood, this could yield real results," says Lincoln computational neuroscientist Jonathan Waddington. He says the game combines scientific knowledge of neuroscience and psychology with expertise in game development. "Clinical trials will get under way this summer to evaluate whether the software could become a valuable new tool for the treatment of children and young adults with visual impairments," Waddington says. The game also features advanced options to adapt the difficulty to the specific cognitive and visual impairment of the person playing. "Research has already shown that this type of training can lead to significant recovery of sight following damage to visual centers of the brain in adults, so it is vital that those using it are motivated by something interesting and engaging," says Lincoln professor Timothy Hodgson.
