    This is real scary. And it goes to prove that bad guys always come up with new ways to steal. I don't believe there is a technical solution to this arms race.

    Instead, I'd love to see our law enforcement friends be more pro-active and setup traps. Pose as a fake victim. Go out and seek those phishing sites. When the thieves come after your money thinking they just ripped off a stupid Internet newbie, then you can trace their activity and catch them.

    That's the best way I can think of scaring the bad guys: when they never know if their next victim might be a cop.

        Problem is with no-script you still have to decide if you trust or not-trust the site and if that level of trust you have is worth what the site is offering.

        If the site offers a useful service which requires scripts you have to decide if it is worth the risk.

        While in most cases it is easy to tell and block only those sites you trust. Those that you don't block may also allow third party scripts to be run such as in ads on the site.

          Problem is with no-script you still have to decide if you trust or not-trust the site and if that level of trust you have is worth what the site is offering.

          That slightly over-simplifies the protection that NoScript offers. For example, even when you allow script to run NoScript still provides protection against certain types of XSS, you can use it to force cookies to be exchanged over https for certain domains, it can block some plug-in types (Java, Flash, Silverlight), it features click-jacking protection, and just a couple of days ago it even added protection against attacks on twitter [hackademix.net].

          So yes, you do have to make that trade-off, but even when you click "allow" you're potentially better off with NoScript installed than without it.

      Well, the nature of an arms race is such that it has technological approaches.

      In this case, for example, there most certainly is a technological approach. JavaScript in one loaded tab in your browser should have no shared knowledge with other tabs in your browser. Data separation needs to be enforced at a finer level. You should also know, if you have two tabs open to different sites, which one of the two a popup is associated with.

      • AFAIK tabs are really just windows. The difference is how they're displayed by the GUI. But from a Javascript POV the tab is just another window. So if we start limiting the knowledge that javascript has over other windows then we prevent a lot of useful, legitimate things that can be done with other windows. For example: I have a few web-apps that use pop-up windows in a non-annoying way (ie: you click something to open the window that actually performs a useful task).

          When you're currently visiting one site, and open a new tab and go to a different site, those two open tabs should have no capacity to share information -- they should function as if they were separate browser sessions. (Obviously this isn't the same as if you clicked on something in a tab that causes another tab or window to open, as they may need to share knowledge. But then, the fact that those two tabs/windows are tied to the same context should be made apparent to the user.)

      BTW, for those of you who are curious about this attack (and are too lazy to RTFA), this basically uses a common image set behind a protected login. e.g.

      <img src="https://www.mybank.com/protected/images/lock.gif" onerror="notLoggedInSoRefresh();" onload="hahaGotEm();">

      If you ping the blasted thing for long enough, you will be able to detect the user logging in. One pop-up later and you've stolen their info.

      Now protecting against this sort of issue is an interesting question. Ideally static resources should never be behind closed doors. But that answer is a bit of a cop-out. The next best thing is to ensure that session cookies are maintained inside the login tab ONLY and that persistent cookies are not used for auto-login.

      (Interesting question: I wonder if Chrome is vulnerable? With process isolation, this trick would require that the main Chrome process delegate the handling of session cookies. Which seems like a bad idea anyway, so I would hope they implemented the browser in a more secure manner.)

      • Wouldn't this mean they'd have to ping every bank? If I bank at www.otherbank.com, loading anything from www.mybank.com isn't going to get them very far. Now, if they sniffed my temp folder for lock.gif or other footprints... that might work.

        so wait..
        as you explain it, I guess the idea is that once the user logs into the secure site, the malware script can magically access the lock.gif because the site and browser tell them that.. yup.. the user is logged in and thus should have access.

        however.. presumably, the script is not from a page that's actually -on- https://www.mybank.com/ [mybank.com].. if it was, you and the bank probably have bigger problems.

        So let's say that instead it's on http://www.malware.lol/ [malware.lol] - why would a script on a page from malware.lol be allowed access to a resource - in this case 'pinging' the 'lock.gif' - *on* https://www.mybank.com/ [mybank.com] ?

        Is there any valid purpose for allowing something like that? I can understand it for non-secure sites.. from inlining content that's hosted on another domain to allowing local applications to grab data off of e.g. websites that do not provide a nice API. But for secure sites? I'm baffled.

          There's a great deal of internet history behind this one. Originally, there were no barriers what so ever. Anyone could link anything from any page. Of course, as Javascript entered the scene and grew in sophistication, this was soon realized to be a problem. In result, most browsers adopted security behaviors for the really powerful stuff like XMLHttpRequest and locked out scripting across frames.

          However, that still leaves a hole like this one. And it's not an easy hole to plug. Quite a few sites are actually structured around the idea of cross-site linking. (e.g. The HTML may be www.mainsite.com while the images come from the web server media.mainsite.com.) Interestingly, this sort of structure is actually a solution to the problem posed. So it's difficult to dispose of it out of hand.

          Some of the web standards are moving toward highly restrictive models for HTTPS sites. e.g. HTTPS resources can only be accessed by pages whose origin is the same HTTPS site. More likely though, I expect to see more explicit security configurations along the lines of what Flash does. Flash uses a crossdomain.xml file on the target site to broadcast if a resource can be accessed or not. This scheme allows for situations like a media server separate from the primary site, but it also allows for those cross domain accesses to be tightly restricted.

          Of course, the scheme is not without its problems. Nothing prevents an attacker from transmitting information he may have collected TO a server that he has configured with a permissive policy file. If he finds a vulnerability that allows him to collect the information in the first place, he's going to be able to make off with the info scott-free.

          In result, web security is an ongoing area of research. It's incredibly complex due to the nature and history of the web, but standards bodies are working hard to find more reliable solutions that don't negatively impact existing sites and current usage.

    The next thing you know, they'll make up a screen scraper in JavaScript. There are several things to learn from this. For the users, one, that you should completely clear your browser (Clear Private Data or similar) before going to a banking website, two that you should NEVER open other websites (or have them open) while you're signed in to a banking website, third that when you've finished banking, you should completely clear your browser again. For the browser makers (Firefox devs reading this?), third party cookies should be disabled by default, the option to turn them on should come with stern warnings, and each website can ONLY read cookies previously set by itself. Further when an encrypted page is opened, its memory should be such that other pages cannot access any part of it. In other words, the same sandboxing approach taken to deal with other security issues, within the browser for encrypted pages.

    Use an Asynchronous request to "curl" out to a well known page of that site and then "grep" the response for typical "you are not logged in" text. If it is not found, commence shenanigans.

    • What if the cookie of the target site is against a host name such as

      http://094ec182f4a74bc1382206407.bank.com/ [bank.com]

      The attacker would not waste their time trying to guess the (randomly generated) 094ec182f4a74bc1382206407 part.

      So when you login your logging in with a host name with a token.

  • From the friendly article: although he and his research team have not spotted full-blown attacks like this in the wild as yet

    I'm sure they will now after this.

  • I already make sure that if I'm going to visit my bank, I close my browser, start a new one, do the banking thing, then close the browser before I do anything else. While banking I don't browse other sites.

    I figured an attack like this was possible but had no idea there was a way to check other sites you are visiting via JavaScript. That seems like a very obvious security flaw. Anyone know how that is possible? Is it via standard JavaScript, or does it require a bizarre hack that happens to work on t

  • I wonder if Chrome's idea of running each tab in a separate process makes it less vulnerable to this type of attack? I suspect that it is much harder for there to be a cross tab or cross window attack via Javascript it each has its own full process.
  • I always see folks bitching and moaning that FireFox burns memory... if you leave it open all day. Why would you do that? I must open FireFox 50 times a a day, and never complain about the extra 1.5 seconds it takes to do that, at least I know I have a "fresh start".

    Often, I also delete all the cookies too, just because I am a neat freak, not due to paranoia. Maybe I get more secure sessions as a side effect.

    Anyhow, keeping your kitchen neat and clean is healthy. Maybe keeping your computer neat and c

      For some reason, FF 3.0 freezes for about eight-ten seconds after I start it up, every single time. It's very, very irritating, and the behaviour encourages me to leave it open as much as possible. (This never happened with FF 1 or 2)

      I have a dual core cpu with gigs of ram, so it's not a hardware issue. Running another profile (with few bookmarks) on the same PC doesn't exhibit the same problem, and I can only assume it's the browser rechecking links, favicons or something else every time I start it up.

    Are you kidding? Internet security clowns have a very limited imagination. They go nuts on securing one aspect beyond usability while completely ignoring other areas.

    Here in NZ there is a problem with ATM machine skimmers. Criminals equip the ATM machine with camera and fake card reader and collect card and pin codes from unsuspecting users after which they raid their bank accounts.

    So everyone is worried about this now. Yet, the most popular form of electronic payment in shops in NZ is the user of a bank ca

  • From TFA: "Klein says placing a low-profile piece of malicious JavaScript on a high-profile Website isn't difficult to do, and the malware is basically invisible to the user."

    I don't see how any well-designed high-profile site wouldn't account for the possibility it might get hacked, let alone not have an automated method for undoing the damage... A simple approach would be to generate an MD5 checksum from each file (i.e. ASP, JPG, flash) and compare it to the MD5 checksums of what they're "supposed" to

    Internet Explorer has a porn^H^H^H^H privacy mode where privacy settings are locked down. Why not build an analagous 'secure mode' for Firefox or Konq. where security settings are all locked to high heaven for that browsing session only?

    That way users can both bank online securely and not have half the web break for them because they've disabled javascript.
  • Here's the novel part of it: it doesn't involve any of the typical attack vectors we all know and love. Instead, it uses JavaScript ...

    Anybody who knows the history of security vulnerabilities in browsers knows that Javascript itself is the all-time-best attack vector. If Javascript is enabled in any browser, that browser can be immediately compromised when you visit a compromised website. There are latent epidemics of Javascript zero-day vulnerabilities in all browsers.

  • No passwords (Score:2, Informative)

    by Haiyadragon (770036)
    Over here in the Netherlands most banks (maybe all) don't use passwords. In my case I have a card reader that will generate a code after I give it my card, PIN number and a code generated by the website. I have to do this to log in and to initiate transactions. That makes this attack pretty useless. Also, a prompt should always clearly indicate by which website it was called and it shouldn't block other tabs.

      Surely banking would be much safer if there was a public key for the bank and a private key for the card stored on the card. The bank would have the private bank key and public card key.

      Then you could use a card reader to create encrypted messages to send to the bank.

      Although it doesn't deal with the problem of if the bank's key gets compromised. They'd have to recall all the cards..
