Facebook Patches Security Threat,Apps acess Personal Info & Modify It..

Facebook has confirmed claims made by Symantec over millions of leaked “access tokens”. These tokens enable an application to access personal information and make changes to profiles, essentially giving third parties the “spare key” to your profile information, photographs, wall and messages.
It is not confirmed whether these third parties (mostly advertisers) knew about the security hole, though Facebook has since told Symantec that the flaw has been fixed. Access granted via these keys could have even been used to mine users’ personal data, with evidence that the security flaw could date back to 2007 when Facebook applications were launched.
Symantec employee Nishant Doshi said in a blog post:
“We estimate that as of April 2011, close to 100,000 applications were enabling this leakage. We estimate that over the years, hundreds of thousands of applications may have inadvertently leaked millions of access tokens to third parties.”
Not Quite Sony
Access tokens are granted when a user installs an application and grants the service access to his or her profile information. Usually access keys expire over time, though many applications request an offline access key which will not change until a user sets a new password.
Despite Facebook using solid OAUTH2.0 authentication methods, a number of older authentication schemes are still accepted and in turn used by thousands of applications. It is these applications, using outdated security methods which may have inadvertently leaked information to third parties.
Nishant explains:
“The application uses a client-side redirect for redirecting the user to the familiar application permission dialog box. This indirect leak could happen if the application uses a legacy Facebook API and has the following deprecated parameters, “return_session=1″ and “session_version=3″, as part of their redirect code.”
Should these parameters have been used (pictured above), Facebook would return an HTTP request containing access tokens within the URL. As part of the referral scheme, this URL is in turn passed on to third party advertisers, complete with access token (pictured below).
Users who are concerned that their access keys have been well and truly leaked should change their passwords immediately to automatically reset the token.
There was no news of the breach on the official Facebook blog, though revised application authentication methods have since been posted on the developers blog, requiring all sites and applications to switch to OAUTH2.0.

Get Ready For Windows 8 ,leaked screenshots,torrent may release Soon

Windows 8 was in the news for a long time now and today, Milestone 1 is leaked on web though currently on private FTP servers as published on Betaarchive. It is expected to soon find its way on Torrents and other file sharing sites.
Win7China and other sources has already quoted that Windows 8 Milestone 3 is ready whereas the leaked build is quite old. Windows 8 Milestone 1 build 7850 has build string 6.1.7850.0.winmain_win8m1.100922-1508. Number 10/09/22 in the string says that internal build which is leaked was compiled on 22nd September 2010.
As I already said, the build is pretty old but if you are curious to try out new Windows 8 features like One click Reset, Aero Auto colorization, User Picture in Taskbar, etc. then you can keep eye when this leak finds public way on your favorite torrent site. Filename is 6.1.7850.0.winmain_win8m1.100922-1508_x86fre_client-enterprise_en-us.iso with file size of 2.45 GB (2,637,101,056 bytes) and MD5 EA2DCFADA6BBA517A0A0649D15E1EB3D
It’s not confirmed whether all the above features are integrated in Milestone 1 because most of them came into light after the build was compiled but curious guys can always try it on Virtual Machine.

Intel® Anti-Theft Technology (Intel® AT) for Laptop Security

Laptop theft is an increasing phenomena in urban India particularly in student hostels and bachelor accommodations. Intel came up with an in-built feature that will shut down the laptop and make it useless for the thief remotely. Though you may not recover the lost laptop, it will act as an deterrent for a possible theft.
This intelligent laptop security technology is built into select 2nd generation Intel® Core™ and 2nd generation Intel® Core™ vPro™ processor families. This technology is built into the processor, so this will be activated even before that startup. By remotely activating it, we can shut the pc. It will work even without internet as it is hardwired and as it starts before startup, it is tamper proof.
There is an additional feature which will alert anyone who starts the laptop that the product they are trying to use is stolen one.
When i was discussing about this technology with my colleagues, many were quite skeptical about the feature being used as a loophole for developing viruses. A friend commented that “Once the remote shut-off has been hacked, there is little to stop someone to set up a iterative program that could continue to dial-up CPUs and shut them down.”
Another one commented that it will give an opportunity to U.S. government to shut down whatever computers they can, whenever they want to.
But i see it as an advantage as this hardware-based technology provides compelling tamper resistance and increased protection. The best feature is Intel AT can now transmit latitude and longitude (using GPS coordinates) to the central server if the system is equipped with a supported 3G module. So you know where exactly your laptop is. But Intel AT is a subscribed service. Intel AT is activated through service subscriptions from Intel AT-enabled software and service
providers.

Check which Application Is Using(Making Slow) Internet,with TCPEye

There might be some instances that your Internet is working properly, but still your browsing speed and downloading speed is very slow as compared to your normal average speed. This may happen because apart from your browser or download manager, various programs may be accessing the internet without your knowledge.
You can find out which other programs are accessing the internet with the help of software TCPEye. TCPEye is a freeware easy to use network monitoring application that will display a list of all the currently opened UDP and TCP/IP ports.
For the particular process that opened the port, all the information regarding that process is displayed, including the process name, full path of the process, version information of the process (product name, file description, and so on), the time that the process was created, and the user that created it, Country Name + Flag. Apart from this, TCPEye allows you to close unwanted TCP connections, kill the process that opened the ports, and save the TCP/UDP ports information to HTML, XML file, or to tab delimited text file and also get it checked for malware.
TCPEye also automatically mark with pink color suspicious TCP/UDP ports owned by unidentified applications. You can right click on any connection to view file properties, terminate the process that is using the connection or close the connection for that specific process. If you find a suspicious connection, you can even scan that process with the integrated VirusTotal Uploader to check if the process is a known malware, virus or Trojan.

Now,RAM can behave as a Flash Memory and vice versa with double-floating-gate FET

Look, we get it, you want DRAM that behaves like flash, flash that behaves like DRAM, and everything in between -- speedy computer memory that doesn't lose its data when the power goes off, and lasts for years on end. Well, it looks there's a new challenger about to enter that ring -- double floating-gate field effect transistors, currently in prototype form at North Carolina State University. Whereas the single floating-gate variety is currently responsible for the flash memory in your USB keys and SSDs, the second floating gate lets bits of data stay in an active, ready state, but the computer can also apply a higher voltage to "freeze" them in place. Since the memory can switch between static and dynamic modes in a single cycle and the data never disappears in between, researchers imagine the new tech could lead to instant-on computers and power-saving techniques that shut down idle memory banks. That's the consumer take, at least -- find the technical deep dive at our more coverage link.
