BBC News - Web code weakness allows data dump on PCs - 0 views

clevercode html5 browser bug

shared by Gabrijela Vrbnjak on 04 Mar 13 - No Cached
  • The loophole exploits a feature of HTML 5 which defines how websites are made and what they can do.
  • Developer Feross Aboukhadijeh found the bug and set up a demo page that fills visitors' hard drives with pictures of cartoon cats. In one demo, Mr Aboukhadijeh managed to dump one gigabyte of data every 16 seconds onto a vulnerable Macbook. Clever code Most major browsers, Chrome, Internet Explorer, Opera and Safari, were found to be vulnerable to the bug, said Mr Aboukhadijeh. While most websites are currently built using version 4 of the Hyper Text Markup Language (HTML), that code is gradually being superseded by the newer version 5. One big change brought in with HTML 5 lets websites store more data locally on visitors' PCs. Safeguards built into the "local storage" specification should limit how much data can be stored. Different browsers allow different limits but all allow at least 2.5 megabytes to be stored. However, Mr Aboukhadijeh found a way round this cap by creating lots of temporary websites linked to the one a person actually visited. He found that each one of these associated sites was allowed to store up to the limit of data because browser makers had not written code to stop this happening. By endlessly creating new, linked websites the bug can be used to siphon huge amounts of data onto target PCs. Only Mozilla's Firefox capped storage at 5MB and was not vulnerable, he found. "Cleverly coded websites have effectively unlimited storage space on visitor's computers," wrote Mr Aboukhadijeh in a blogpost about the bug. Code to exploit the bug has been released by Mr Aboukhadijeh and he set up a website, called Filldisk that, on vulnerable PCs, dumps lots of images of cats on to the hard drive. So far, no malicious use of the exploits has been observed. In a bid to solve the problem, bug reports about the exploit have been filed with major browser makers.

  • Adults must impose the necessary checks and balances to keep children safe online, says the children's commissioner for Wales.
  • "All children and young people don't seem much of a distinction between their online and offline lives,"
  • Mr Towler told BBC Radio Wales. "It's all just one thing and they get really excited by the opportunities the internet affords and sometimes parents get a little scared about that and worried about what their children are accessing." 'Crossing the road' Continue reading the main story “Start Quote They're all running around with handheld computers these days, they're not just on phones ” End Quote Keith Towler Children's commissioner Mr Towler said he talks to children in lots of different settings and they "still enjoy playing outside as much as they ever did". He said we need to recognise that the internet provides fantastic opportunities for education and learning and its making sure that children access that safely. He said that was a real challenge for parents and carers. "It's a bit like crossing the road, you try to teach your children the best way of crossing the road well. We need to teach our children the best way of using this fantastic resource. "I think too many parents are very very scared of the internet and because they're so scared they will say 'Oh I don't understand it'". Handheld computers The commissioner also praised Hwb, the virtual learning environment, which he said provides protection for children using the web in schools. Mr Towler said: "We've got to get parents and carers to recognise that children do operate in the digital world. They're all running around with handheld computers these days, they're not just on phones. "They can access whatever they want whenever they want and parents need to engage on that. " "We need to remember that children and young people are much more savvy than sometimes we think they are, and they are much more responsible than sometimes adults think they are so its not all doom and gloom. "What we need to do is put the right checks and balances in place and what children always want from parents and carers is to understand what the boundaries are, and that's our job to do that." Sangeet Bhullar, executive director of Wise Kids, added that the digital landscape was "evolving rapidly" and up-to-date data was needed on how children and young people in Wales related to it.

  • Is Yoda, You Are Luke: How the Video Site Became Our Storehouse of Folk Knowledge
  • What makes it special is that YouTube taps people who want to show you what they know, not write about it. Learning from YouTube is more like a momentary apprenticeship than it is like book learning, and that's what makes it so great.
  • I started Googling.

  • Somehow, then, perhaps Google surfaced the video through search, I found my way to YouTube
  • What I love about this kind of knowledge transfer is that it's so human. The video is shot from a first-person point-of-view, the narrator talks directly to you, and there are no cuts.
  • If you start to search around on YouTube for various household fix-ups, you find all kinds of people posting similar how-tos.
  • But mostly it's just helpful people who decided to record a video and post it to YouTube for some reason.

  • Firefox OS won't magically succeed just because it's open source - see webOS The siren song of open source means some people think Firefox OS could take the smartphone market by storm - but that's what they thought about webOS
  • Open source" operating systems are the siren call of the internet. For years, we were promised, Linux was going to be the Next Big Thing on the desktop; the tired old empires of Windows and MacOS were going to be pushed aside, and everyone was going to embrace Linux (though quite which distro wasn't clear). From infants to grannies, they would all see the light, and install software that was built with the user in mind - as long as the user was someone who could hold the idea of the concentric circles of file ownership (root/wheel/std) in their head
  • Despite the fevered imaginings of a fair number at the time, there was simply no chance that webOS was going to go anywhere without direct help from HP; and HP wasn't going to give it that help, since it had plenty of troubles of its own.
  • ...8 more annotations...
  • LG has indicated that it will be using webOS in its Smart TV line (which, in passing, suggests that Google's hopes of having a multi-manufacturer-pronged assault on the living room with Google TV are being chipped away; Samsung has gone its own way, Sony offers a mixture of Google and its own smart TV offerings, and now it looks like LG isn't exactly all-in). Though that might, in time, become something that it uses on phones or tablets, you'd be crazy to bet on it. LG is smart enough to know that TVs are a world away from phones and tablets, both in terms of the user interaction experience, and the demands that they make for user acceptance.
  • But the siren song of open source OSs becomes deafening when you look at the other announcement to come out of Mobile World Congress, in which Mozilla is touting its Firefox OS as the anathema to the world's ills - or at least those afflicting the smartphone industry. What does Moziila chief executive Gary Kovacs think is going to be the unique selling point of the Firefox OS phones that he expects to see in 2014? "Our goal is to level the playing field and usher in an explosion of content and services that will meet the diverse needs of the next two billion people online," he said in Barcelona, adding "We're not trying to get in the middle of an operating system fight; what we are trying to do is be the catalyst to drive more development around the open web."
  • The problem for Firefox OS is that it doesn't have a dedicated hardware backer. Sure, Sony has said that it will make some phones using it. ZTE and Alcatel say they will build hardware that will run it. And Kovacs points to the fact that Firefox OS will run HTML5 apps - not "native" apps (in the sense that iOS or Android apps run natively). That might put a questionmark over whether, by some analysts' measure, the FFOS phone is truly a "smartphone", since their definition for that includes "running apps on a native API". (That's why Gartner and IDC don't class Nokia's Asha phones as smartphones.)
  • So how did Android succeed? Three things. First, Google get a vibrant app ecosystem going even before there was a single phone: it had competitions for apps, with a $10m fund to seed developer ideas. By April 2008 there were almost 2,000 Android applications; two-third came from outside the US. Among the offerings: photo-enhanced driving, on-the-fly party mashups with maps, maintaining passive surveillance on your family's whereabouts. (Some things never change.) Second, it was able to go to Verizon, which was looking enviously at how AT&amp;T was able to offer the iPhone, and suggest that Android phones - when they came along - could be the answer to that competitive challenge. And third, it was Google - the gigantic search-engine-and-everything-else company with the international reputation. If Google was doing a new generation of smartphone software (and if Apple had validated the idea), then it looked like a good deal for everyone. And handset manufacturers were eager to find an alternative to Microsoft.
  • Android is gigantic - some version of it might be on a billion phones this year - meaning there's no obvious need for another open source OS. What, after all, is FFOS actually going to do that Android doesn't, or that iOS or Windows Phone or BlackBerry can't? Yes, we've heard that the target isn't the west, but the developing world; that still doesn't explain why a Chinese handset manufacturer would deploy FFOS rather than Android, whether the Google version or a forked one that could connect to a local app store.
  • Even worse, FFOS is at an immediate competitive disadvantage because the principal browser on smartphones now is based on WebKit. Chrome uses it, MobileSafari uses it, BlackBerry uses it, and Opera uses it too now. That leaves only Internet Explorer on Windows Phone standing alone. Developers writing HTML5 apps will naturally write for compatibility with WebKit, which is always going to behave slightly differently from Firefox's Gecko rendering engine. For FFOS's sake, you have to hope the differences aren't big.
  • That's the trouble with the magical thinking that often attaches to open source projects. Making webOS open source didn't solve its problems; it simply shoved them off into a siding. Having an open source mobile OS didn't guarantee Android's success; the efforts of Google, and the timing in the market, did that.
  • Perhaps for that reason, people have high expectations for the Ubuntu OS and phone, with its fabulously complex array of gestures for control. Bad news, dreamers: it's going to fail in the market too if Canonical attempts to market it as a hardware-software combination - that is, sells Ubuntu phones at retail.

  • The prediction of Web 2.0's demise was made by Christopher Mims, a technology commentator who writes for the MIT journal Technology Review. He started by typing Web 2.0 into Google Trends search engine
  • As it happens, Web 2.0 does mean something, even though the definition gets a bit fuzzy round the edges. It first appeared in 1999
  • if the internet itself was the platform on which Web 1.0 – the first version of the Web as a simple publication system – was built, then Web 2.0 was the platform on which new, innovative&nbsp;&nbsp;applications could be&nbsp;built.
  • Online mapping systems
  • Image-hosting services
  • social networking services such as MySpace, Orkut, LinkedIn, Facebook and Twitter.
  • Cloud computing
  • So one way of looking at Web 2.0 is simply to say that it's "the web done properly"
  • The big question, of course, is what will Web 3.0 be like? And the answer, I suppose, is that if we knew that then we wouldn't be here.

  • Google raises privacy fears as personal details are released to app developers Campaigner says tech giant's policies don't make it clear that Google Play users who buy apps give over information
  • Charles Arthur guardian.co.uk, Monday 25 February 2013 14.39 GMT
  • Google Play: the personal details of app buyers are released to developers Google could face a third privacy row in a two years, after a leading campaigner called for the US government to investigate the fact that the names, geographic region and email addresses of people who buy apps from its Play store are passed on to the app developers without users' explicit permission.
  • ...5 more annotations...
  • Ben Edelman, an associate professor at Harvard Business School, says that analysis of Google's terms and conditions relating to its Google Play store and Google Wallet transaction system (used for buying apps) doesn't show any clauses where users are specifically told that their emails will be sent on to the developer. He also warns that developers could use that information to "track and harass" people who have given apps low ratings or requested refunds. And hackers – or malicious developers – could create personalised emails to send out to people to steal passwords (phishing) or install "updates" that were actually malware.
  • Google says it has to provide some location data about which country apps are bought in so developers can calculate the correct amount of tax to pay. But that does not explain why it passes on buyers' names and email addresses, which together with a postcode could be used to identify a person's location and address."Google's prior privacy blunders have put [it] under higher scrutiny," Edelman says, pointing to the 20-year consent order with the US Federal Trade Commission that Google signed in March 2011 in the wake of its Buzz social network fiasco – followed by a record $22.5m fine in August 2012 for hacking Apple users' browsers to install tracking cookies. It has also been fiercely criticised in Europe for its changes in March 2012 to its privacy policies, which data protection chiefs said could mean "uncontrolled" use of personal data.
  • Eric Butler, a freelance software developer of the Tapchat and Farebot apps, tweeted in July 2012 "I wonder if most Android users realise that when you buy an app in the Play Store the seller [of the app] can see your name, email address and phone."Following the row, he has noted on his blog that "Because the entire experience of purchasing Android apps is so sloppy, it's not unreasonable to assume that this privacy issue was actually an oversight." But, he says, "Google should follow Apple's lead and offer users and developers better privacy protection."
  • Another developer, Jesse Wilson, pointed out the same problem in November on Google+, and was quickly echoed by Chris Lacy, who said that "as a developer I never asked for this information, I have no need for it, and I simply do not want to be a custodian of such information."Lacy added that "As a consumer, this is distressing on many levels: there is no fair warning that this information will be transferred … trusting my personal information to Google is one thing. But with this system, users are unknowingly having to trust their information to a third party. There's no way to know what security measures that third party might have in place." He added that it meant that the app developer "has gained my personal information without requesting the appropriate permissions via the app."
  • Google has said that passing on the details does not breach its privacy conditions. In a quote to Siliconvalley.com, a representative told the site that "Google Wallet shares the information necessary to process a transaction, which is clearly spelled out in the Google Wallet privacy notice."

  • Amanda Holpuch guardian.co.uk, Tuesday 19 February 2013 22.42 GMT
  • A blogger has published once-classified FBI files that show how the agency tracked and collected information on internet activist Aaron Swartz. Swartz, who killed himself in January aged 26, had previously requested his files and posted them on his blog, but some new documents and redactions are included in the files published by Firedoglake blogger Daniel Wright.Wright was given 21 of 23 declassified documents, thanks to a rule that declassifies FBI files on the deceased. Wright said that he was told the other two pages of documents were not provided because of freedom of information subsections concerning privacy, "sources and methods," and that can "put someone's life in danger."

  • The FBI's files concern Swartz's involvement in accessing the Public Access to Court Electronic Records (Pacer) documents. In pursuit of their investigation, the FBI had collected his personal information and was surveilling an Illinois address where he had his IP address registered. Aaron H. Swartz FBI File by Daniel Wright
  • One page reads: "Washington Field Office requests that the North RA attempt to locate Aaron Swartz, his vehicles, drivers license information and picture, and others. Since Swartz is the potential subject of an ongoing investigation, it is requested that Swartz not be approached by agents." The FBI also collected information from his social networking profiles, including Facebook and Linkedin. The latter proved to be a catalog of his many notable accomplishments, which include being a co-founder of Reddit, a founder of a website to improve the government, watchdog.net and as metadata adviser at Creative Commons.
  • Information from a New York Times article about his Pacer hack was also included in the files, though strangely, since the article can still be read online, the name of the article's other subject, Carl Malamud, was blocked out.Hacking collective Anonymous released a State Department database Monday in memory of Swartz. The files included employees' personal information such as addresses, phone number and emails.
