CHINA charges Microsoft windows 8 for backdoor-spying

Microsoft and China are at odds over the issue of cyberspying, with Windows 8 caught in the crossfire.

State-run broadcaster China Central Television lashed out Wednesday at the latest version of Windows and charged that it's capable of collecting a huge amount of data on Chinese society. In a transcript of the CCTV interview published by the Wall Street Journal, an academic shared his opinion on the type of data that Microsoft can allegedly collect through its OS.

"It's very easy for providers of operating systems to obtain various types of sensitive user information," Ni Guangnan, an academician at the Chinese Academy of Engineering, told the interviewer. "They can find out your identity, your account information, your contact list, your mobile phone number. With all that data together, using big data analysis, a party can understand the conditions and activities of our national economy and society."

Adding fuel to the fire, Guangnan pointed to the classified documents leaked by former National Security Agency contractor Edward Snowden as proof that Microsoft has worked with the US government to obtain encrypted data over the Internet.

In response, Microsoft used its own Weibo account to refute the charges and deny all allegations of backdoor spying in collaboration with the US government. As translated in a story by Neowin, Microsoft's denials break down into five points. According to Neowin, Microsoft said it has:


  • Never "assisted any government in an attack of another government or clients."
  • Never "provided any government the authority to directly visit...products or services."
  • Never provided a "backdoor" to products or services.
  • Never provided client data or information to the US government or the NSA.
  • Never "concealed any requests from any government for information about its clients."

Microsoft's war of words with China is part of a larger skirmish between the US and Chinese governments. Charges of cyberspying between the two countries is nothing new. But since the revelations of NSA spying activities were leaked last year, China has used the opportunity to accuse such companies as Microsoft, Google, and Apple of cooperating with the NSA to gather data and steal state secrets. Tech companies have acknowledged that they are required to share certain customer data at the request of the government but have denied that they collaborate with the government or build backdoors into their products and services to allow data to be siphoned.

Such charges can damage a company's reputation and bottom line. In the case of Microsoft, China last month announced a ban on Windows 8 for government computers. At the time, China's state-run Xinhua news agency said simply that the ban was designed to improve security. However, China likely has another motive for wanting to put the kibosh on Windows 8 beyond security fears.

Microsoft has long accused China of widespread piracy of Windows. In 2011, former CEO Steve Ballmer told employees that Microsoft's revenue in China represented only 5 percent of sales in the US although the two markets were about the same size, according to the Journal. As such, a significant number of the PCs in China still running the now-unsupported Windows XP may be using illegal copies.

Microsoft wants to implement a server-based licensing system in China as one way to fight software piracy, the Journal added. And since the software giant no longer sells or supports Windows XP, Chinese consumers would be forced to upgrade to a more modern operating system, such as Windows 8.

MTGOX world's largest bitcoin trading website turned OFFLINE ~ Hack4friends

MTGOX world's largest bitcoin trading website turned OFFLINE ~ Hack4friends


As we all know in recent days the virtual currency-Bitcoins gained much popularity among all countries's people. And its exchange value to US Dollars raised to 1200$. But now its going to smashed because its exchange values is also decreasing day by day and today its value downed to 425.304$(Biggest fall).




MTGOX got much popularity in few months and ranked as No. 1 online bitcoin trading website.But now website is disappeared from internet and a blank page is left on their website. People from all countries have invested so millions of Dollars($) for online trading with Bitcoins but MTGOX disappeared with all money.
Mark Karpeles, CEO of the pioneering but troubled Bitcoin exchange MtGox, has resigned his seat on the board of the Bitcoin Foundation, the organization that standardizes and promotes the cryptocurrency.

MtGox, which handled the bulk of Bitcoin transactions until fraudulent hacking forced it to freeze withdrawals earlier this month, has had serious liquidity problems since last year. Though others were subsequently hit too, Bitcoin Foundation chief scientist Gavin Andresen blamed the exchange rather than the core protocol for the episode, and MtGox’s systems have struggled to recover.
                                   
                              
                                           All tweets are deleted by MTGOX

The Tokyo-based company has repeatedly promised a fix but failed to deliver. Its most recent communication was on Thursday, claiming that “security problems” had forced it to relocate, slowing down its progress in fixing its records after the attack. It’s not clear whether this is a reference to the couple of angry bitcoiners who were camped outside the MtGox offices, demanding their money.

In a statement on Sunday, the Bitcoin Foundation said it was “grateful for [MtGox's] early and valuable contributions as a founding member in launching the Bitcoin Foundation.” A request for comment from MtGox itself had gone unanswered at the time of writing, though as many have noted the company has deleted its entire tweet history, so take from that what you will.

We also contacted to MTGOX via their old email addresses but till now we have not got any response from their side about it all.

Snapchat hack spams users with smoothie photos ~ Hack4Friends

Snapchat hack spams users with smoothie photos ~ Hack4Friends

Snapchat is combating yet another security issue, and it's a juicy one.
In a story posted late Tuesday, Wired editor Joe Brown said his Snapchat friends were asking why he was sending them messages with photos of fruit smoothies. That was a surprise to Brown because he hadn't sent any such messages. Other Snapchatters have since complained about receiving these same messages, according to a Twitter search.
The messages serve up a URL for a company called Snapfroot, which then redirects the recipient to an AllRecipes.com page for a "Berry Delicious" smoothie. The spam outbreak so far seems innocuous, albeit annoying, but it does point to yet another vulnerability for the photo-sharing site.

Snapchat told Brown that these messages have been bouncing around the past couple of days.
"It's mostly cases where someone has your e-mail address and password and gets in on the first try," an anonymous Snapchat spokesperson told Wired. "We're not seeing any evidence of brute-force tactics."
Snapchat is trying to plug the leak. In the meantime, site users may want to change their passwords. The spokesperson also advised people to stay away from third-party apps that ask for your Snapchat username and password.
"Yesterday a small number of our users experienced a spam incident where unwanted photos were sent from their accounts," a Snapchat representative told Reuters. "Our security team deployed additional measures to secure accounts. We recommend using unique and strong passwords to prevent abuse."

Wickr 2.0 makes self-destructing SMS -- Care about Privacy

Wickr 2.0 makes self-destructing SMS -- Care about Privacy


Wickr 2.0's debut on Friday makes it much easier to invite friends to use the app, thanks to a new address-book scanning feature that prevents Wickr from learning who you're inviting. That's a big difference from just about every other service out there, which accesses your address book -- usually with your permission -- and then holds on to that data like the digital gold that it is.
Nico Sell, co-founder of Wickr, said that it was important to the company to avoid holding any sensitive information about its customers on its servers
 "Unlike other apps, Wickr does not upload your contact book to our servers; your contacts never leave your device," she said. "We create a cryptographic representation of your contacts that we store on our servers to match with your friends."

Available now on iOS and on Android in the next few days, the Wickr update still uses some of the toughest standards for major encryption protocol available. It uses
ECDH-512 encryption to protect your data; ECDH-512 for the security key exchange; RSA-4096 both as a backup and in legacy versions of the app; and SHA-256 for Transport Later Security and hashing. Once it encrypts a message, the keys are used only once then destroyed by the sender's phone. Since Wickr's servers don't have the decryption keys, there's no way for Wickr to access your messages.

Whit Diffie, co-inventor of the ECDH standard, is a Wickr adviser. The company boasts a veritable who's who roster of privacy bona fides on its advisory board, including Cory Doctorow, Paul Kocher, and Brian Behlendorf.

On top of all that, the service deletes attachment metadata to ensure that the company knows even less about you.

Sell thinks that her free app is at the forefront of a new movement to protect people from government intrusion, no small effort in the wake of the NSA leaks by Edward Snowden.

 "I believe this is the first bacterial growth app ever invented," she said, explaining "bacterial" as being "beneficial to society."

"We plan to license this piece of tech to all the messaging apps in trouble with regulators for abusing users' contact books," Sell said of Wickr's business model.

Wickr 2.0 ditches the mostly-red interface for a streamlined white one with red accents. While the interface makes the app easier to use, the company has invested in other usability features to compete more directly with its competition.

You can now finally reset your password without it being as big a hassle as before; customize your avatar, contact names, and group names; invite multiple friends at once; and send insecure e-mail or SMS from Wickr. For the last one, it warns you when you're about to send a message to a non-Wickr recipient.

Wickr still may not be for everyone, but for people who value sending private messages privately that are authentically difficult -- if not impossible -- to be read by anyone but the intended recipient -- then Wickr is one of the best messaging apps around.

Snowden's Christmas message about Privacy of ordinary person

 Snowden's Christmas message about Privacy of ordinary person

Edward Snowden, the National Security Agency whistleblower, delivered a video message on Christmas Day via UK's Channel 4 with a simple theme: "privacy matters."

"A child born today will grow up with no conception of privacy at all. They'll never know what it means to have a private moment to themselves -- an unrecorded, unanalyzed thought," Snowden said in the 1-minute, 43-second message. "And that's a problem because privacy matters. Privacy is what allows us to determine who we are and who we want to be."


          Must watch this video if you care about your privacy


Snowden referenced George Orwell's "1984" and noted the book's dystopian visions of microphones, video cameras, and televisions that watch people "are nothing compared to what we have available today. We have sensors in our pockets that track us everywhere we go." 


 He also used the message as an appeal to people everywhere to rally against widespread surveillance.

"The conversation occurring today will determine the amount of trust we can place both in the technology that surrounds us and the government that regulates it. Together, we can find a better balance," he said. "End mass surveillance. And remind the government that if it really wants to know how we feel, asking is always cheaper than spying."

UK's Channel 4 chose Snowden for its annual alternative message and response to Queen Elizabeth's annual Christmas address.

Snowden has temporary asylum in Russia following his leaks earlier this year about the National Security Agency's extensive electronic surveillance programs. The US Justice Department's charges against him include violations of the Espionage Act.
