SIM cards vulnerable to hacking


Hundreds of thousands of mobile phones may be vulnerable to spying because of the utilization of outdated, 1970s-era cryptography, in accordance to new exploration because of be presented on the Black Hat security conference.

Karsten Nohl, an professional cryptographer with Protection Research Labs, has discovered a method to trick mobile phones into granting accessibility to the device’s spot, SMS functions and allow modifications to a person’s voicemail amount.

Nohl’s analysis looked at a mobile phones’ SIM (Subscriber Identification Module), the little card inserted into a device that ties it to a telephone amount and authenticates computer software updates and commands sent over-the-air from an operator.

A lot more than 7 billion SIM cards are in use globally. To make certain privacy and safety, SIM cards use encryption when communicating with an operator, however the encryption standards use fluctuate extensively.

Nohl’s analysis found that a lot of SIMs use a weak encryption conventional dating in the 1970s known as DES (Data Encryption Typical), according to a preview posted on his company’s blog.

DES has long been considered a weak type of encryption, and many mobile operators have upgraded now to far more safe types. It truly is reasonably easy to find the private essential employed to signal articles encrypted with DES.

In its experiment, Safety Investigation Labs sent a binary code in excess of SMS to a device utilizing a SIM with DES. Because the binary code wasn’t properly cryptographically signed, it would not run to the gadget.

But although rejecting the code, the phone’s SIM tends to make a essential mistake: it sends back more than SMS an error code that carries its personal encrypted 56-bit private important, according towards the company. Due to the fact DES is thought of an extremely weak form of encryption, it’s achievable to decrypt the personal crucial utilizing identified cracking methods.

Safety Exploration Labs did it in about two minutes on the typical laptop or computer together with the assistance of the rainbow table, a mathematical chart that helps convert an encrypted private critical or password hash into its authentic type a lot quicker.

Using the private DES key in hand, it really is then probable to “sign” malicious software program updates together with the key, and send individuals updates to your gadget. The device believes the software originates from a legit supply after which grants accessibility to sensitive data.

The enterprise outlined an assault situation towards SIM cards that run some type of Java virtual machine, a computer software framework for Java applications.

Making use of the SIM’s personal important, an attacker could force the SIM to download Java applets, that are fundamentally extremely small applications that complete some function. These applets would be “allowed to send SMS, alter voicemail numbers, and query the telephone place, amongst numerous other predefined functions.”

“These abilities alone present lots of likely for abuse,” the enterprise wrote.

Possible treatments for the problem such as ensuring SIM cards use state-of-the-art cryptography and also working with Java virtual machines that restrict applets’ entry to particular information and facts.

Nohl’s presentation, ”Rooting SIM cards,” will consider area in the Black Hat protection conference in Las Vegas on July 31.

Google Earnings: Profit Up but Search-Ad Prices Drop 6%


Google Inc's profit and income continued to climb from the latest quarter, but deceleration from the growth of its primary business of marketing search advertising reignited considerations regarding the affect of mobile gadgets as well as Web giant's push into lower-margin firms.

The results had been reduced than what Wall Street was expecting, sending the company's shares lower in after-hours trading.

Google on Thursday reported a 20% rise in income from its core business awhich excludes its Motorola hardware unit?ain the 2nd quarter, slightly less than the 22% revenue rise in the prior two quarters. The company also posted a 16% rise in revenue to the 2nd quarter in a row.

But Google couldn't stem a drop in search-ad rates. The cost-per-click, or the selling price that advertisers paid Google each time an individual clicked on an ad in its internet search engine, fell 6% from a yr earlier, worse compared to the 4% year-over-year drop in charges all through the 1st quarter. Analysts had expected rates to fall by only about 3% inside the 2nd quarter.

In the course of an earnings phone with analysts, Google's chief economic officer, Patrick Pichette, stated clearly, mobile has some effect, but that general the health from the company was good, given that Google noticed 23% a lot more clicks on its ads within the 2nd quarter compared by using a 12 months earlier, offsetting the reduce costs.

Google's shares fell more than 4% in after-hours trading Thursday following finishing earlier at $910.68, or down significantly less than 1%, over the Nasdaq Stock Industry.

The CPC drop is usually a bit surprising, and perhaps raises once more the question of no matter whether Google truly positive aspects through the Mobile shift, stated Mark Mahaney, a stock analyst at RBC Capital Markets.

Search-ad rates happen to be declining since the fourth quarter of 2011. Analysts attribute the drop towards the fact that prices for showing ads on web sites which have been accessed via mobile gadgets have lengthy been reduce than charges for adverts viewed on PCs.

Google executives have stated repeatedly that they don't believe mobile devices would harm Google's company in the long lasting.

The enterprise is looking to improve the mobile-ad rates by requiring advertisers working with Google's AdWords online-ad system to implement the enhanced campaigns? characteristic and pay out for advertisements on tablet units when they need to market on PCs, amongst other matters

Chief Small business Officer Nikesh Arora explained YouTube's mobile income in June of this 12 months was triple its revenue while in the starting in the year, although he didn't give specifics.

He explained that several advertisers weren't addressing the mobile chance appropriately, and that Google has aided numerous of them to increase their marketing achievement with people on mobile devices.

Google's online-ad revenue growth continues to outpace the general development seen during the online-ad industry, most analysts say. Rival Yahoo Inc. earlier this week reported a 7% drop in income because of market-share losses in its sale of on line adverts. Social network Facebook Inc., Google's other principal competitor during the online-ad market, reviews second-quarter final results subsequent week.

During the analyst phone, Chief Executive Larry Webpage said he would continue to invest the vast majority of our sources and time in our core products, this kind of as Google's Android mobile working procedure that powers smartphones, tablets along with other units.

Far more than 900 million Android products have been activated because the launch of Android in late 2008, and one.five million devices are remaining activated every single day, he said. Google generates income from Web-search, Google Maps, YouTube and other apps which are preinstalled on Android gadgets.

Mr. Web page additional that Google will carry on to invest in riskier, longer-term projects this kind of as working with high-altitude balloons to supply Net accessibility to persons in remote regions, between other efforts.

Google has worked to slim down its troubled Motorola hardware-design and manufacturing unit, which it acquired in May perhaps of last 12 months. But on Thursday, Google mentioned Motorola posted a second-quarter reduction of $342 million, up from a $271 million reduction within the initially quarter.

The business strategies to invest around $500 million to industry Motorola's new flagship smartphone, the Moto X, starting later this year and it's functioning on a number of other gadgets, persons acquainted with all the matter have said.

The losses at Motorola, amongst other elements, contributed to Google's lower-than-expected earnings per share of $9.54 within a 2nd quarter, up 13% from $8.42 a 12 months ago. Analysts had been expected earnings of about $10.80 a share.

While in the get in touch with, Mr. Arora explained development in Google's emerging business lines was accelerating. People consist of hardware, such as laptops based upon Google's Chrome operating system, that are accessible in extra than six,000 brick-and-mortar merchants, and Google's suite of enterprise application and cloud-computing solutions that assistance corporations this kind of as LinkedIn Corp. and Snapchat Inc. run their Net solutions. He didn't give revenue figures.

General, Google's second-quarter profit of $3.23 billion was up from $2.79 billion a yr earlier. Like its Motorola unit, Google's income rose by 19% to $14.eleven billion inside the 2nd quarter.

Its head count was 44,777 at the end of June, down from 53,891 with the end of March, largely due to the layoffs at Motorola earlier this year.

Hackers ask the federal government not to participate in its annual meetings

Def Con hacker annual meeting request not to participate in the federal government, which is the first time in 21 years to mention meeting this requirement, said Snowden information disclosed on the federal government to make some hackers presence of the person feel uncomfortable.
 
 
"If the federal government does not participate in this year's Def Con conference, good for everyone." Def Con founder Jeff Moss at the meeting on Wednesday night, said in a statement posted on the website.
 
 
August 2 began meeting in Las Vegas expected to have over 15,000 hackers, researchers, corporate security experts, privacy advocates and artists who attend.
 
 
Moss is the U.S. Department of Homeland Security network security consultant, he told Reuters that such a decision is not easy, but he thinks Def Con takes time to accept the recent disclosures about the U.S. surveillance practices.
 
 
"Everyone in the digestion of the federal government over the past 10 years to understand and reach a compromise thing. (To us) some time and a certain distance is beneficial, especially when feeling a bit emotional time." Moss said.
 
 
He said the move is not to create tension, but defuse tensions. "We will not catch a ghost or check the identity and the people kicked out."
 
 
Hacker conference held this past attracted the CIA (CIA), National Security Agency (NSA), Federal Bureau of Investigation (FBI), President of the Secret Service and military officials in the various departments involved.

Twitter surrenders user data to French government


CEO Dick Costolo's Twitter was forced to turn over data that will allow the French government to ID the service's users. Photo: Lionel Cironneau, Associated Press


Twitter has turned over data on its users that will help French authorities identify which of the microblogging service's users published anti-Semitic messages, a violation of French law.

The company had been fighting - and losing - in rounds of appeals in French courts in order to protect the users' identities, going so far as to not immediately comply with a French judge's orders, but eventually acquiesced.

This development does damage to one of the company's largest value propositions: that people can speak freely - and anonymously - on the service. In volatile nations like Egypt, Iran and Syria, dissidents have used the services to organize and communicate during uprisings. Many analysts see such tools as integral in marches toward freedom and democracy. In the U.S., much of the Occupy protests were organized on Twitter.

Yet others counter that Internet tools also create an easy way for governments to identify those dissidents, should they get access to the data, and that's what's happened here. What will happen to the racist tweeters remains to be seen.

"This disclosure puts an end to the dispute between the parties, which have agreed to actively continue contributing together to the fight against racism and anti-Semitism, in keeping with their respective domestic laws and regulations," Twitter and the French Union of Jewish Students said in a joint statement.

In October, the hashtags #UnBonJuif (a good Jew) and #UnJuifMort (a dead Jew) appeared in tweets alongside offensive comments. Twitter promptly deleted the tweets.

The Jewish students' union took Twitter to court anyway, demanding the users' personal information. France has laws against publishing racist and bigoted hate speech.

Twitter has claimed it will always try to follow national laws when dealing with legal matters that pertain to a specific country - but in this case, it tried, unsuccessfully, to fall back on the U.S. protections of freedom of speech.

Human copter? Well, humans can fly now.

OK, maybe we won't be flapping through the Grand Canyon any time soon, but researchers have managed to get a human-powered helicopter to stay aloft for about a minute.

In a video that might remind one of the crafts trying to get airborne during the time of the Wright Brothers, a contraption called Atlas remained aloft for 64.11 seconds and reached an altitude of 3.3 meters. In doing so, a collaborative group in Canada called AeroVelo was declared the winner of the Igor I. Sikorsky Human Powered Helicopter Competition by the American Helicopter Society. They'll bank $250,000 for the effort.

And effort is certainly the keyword. As you can see in the video - online at http://bit.ly/12wWoDj - human-powered flight has a long way to go. The contraption is completely - hilariously - impractical and the guy powering the bike, which makes the rotors turn, has quads that would make a linebacker jealous.

But the group is optimistic nonetheless.

"We would like the public to understand that with innovative engineering and creative design we can find sustainable and environmentally conscious solutions to many of the technological challenges facing our generation," the group wrote in a blog post.

Human-powered helicopters may be a long way off, and not a solution to world problems. But this one at least captures the imagination - if only for a minute.

Google reportedly prepared to spend $500M marketing Moto X


Google is apparently going all in to support the Moto X, the first flagship handset released by Motorola Mobility since being acquired by the Web giant a year ago.

Google is expected to allow the unit to spend up to $500 million marketing the highly-anticipated smartphone in the U.S. and overseas, people familiar with the matter told The Wall Street Journal. The device is expected to be available on AT&T, Sprint, T-Mobile, and Verizon Wireless this fall, sources told the Journal.

With an emphasis toward customer convenience and customization, Motorola has reportedly taken steps to limit "bloatware," the apps and services pre-installed on handsets by carriers that are often useless and difficult to remove without rooting the device. Customers will be able to choose the colors for the back of the device and the trim and engrave a name or message to the back cover, ABC News reported earlier this month.

A Motorola spokesperson declined to comment on the report.

Beyond a solid partnership with Verizon, Motorola has struggled to sell its Android smartphones. With Google's backing, the Moto X represents Motorola's best chance in years to make inroads against Apple and Samsung.

After months of rumors and speculation, a sign-up page for the Moto X handset finally went live earlier this month, offering users access to the product information and promotional offers. The page, which touts the Moto X as "the first smartphone designed, engineered and assembled in the USA," promises that the handset is "coming soon."

Motorola said it expects to have more than 2,000 new employees at a Fort Worth, Texas, facility building the phones. The domestic location will enable the phones to arrive in customers' hands within days of their order, according to ABC News.
