Researcher Claims To Have Chrome Zero-Day, Google Says "Prove It" 106

chicksdaddy writes "Google's been known to pay $60,000 for information on remotely exploitable vulnerabilities in its Chrome web browser. So, when a researcher says that he has one, but isn't interested in selling it, eyebrows get raised. And that's just what's happening this week, with Google saying it will wait and see what Georgian researcher Ucha Gobejishvili has up his sleeve in a presentation on Saturday at the Malcon conference in New Delhi. Gobejishvili has claimed that he will demonstrate a remotely exploitable hole in the Chrome web browser at Malcon. He described the security hole in Chrome as a 'critical vulnerability' in a Chrome DLL. 'It has silent and automatically (sp) download function and it works on all Windows systems,' he told Security Ledger. However, more than a few questions hang over Gobejishvili's talk. The researcher said he discovered the hole in July, but hasn't bothered to contact Google. He will demonstrate the exploit at MalCon, and have a 'general discussion' about it, but won't release source code for it. 'I know this is a very dangerous issue that's why I am not publishing more details about this vulnerability,' he wrote. Google said that, with no information on the hole, it can only wait to hear the researcher's Malcon presentation before it can assess the threat to Chrome users."

      He's doing it for fame, not for profit. By selling out a single hole, he gets a one-time check. By talking about it in the abstract, he gets attention. Perhaps a lot of attention, and people listening to him speak. Some people value attention more than money.

        I particularly like this part from his bug report:

        VERSION
        Chrome Version:Ubuntu 11.4 version
        Operating System: [Ubuntu 11.4]

        Man I love that version of chrome. What do you call a security researcher who cant even identify his platform in his bug reports?

          • When you go to the Chrome "about" screen, I dont believe the words "ubuntu 11.4 version" ever pop up. I believe the version is an all numeric string that is the same regardless of what language you speak, like "23.0.1271.64 m"

      He has a video of the Google Chrome exploit that he discovered up already:

      http://youtu.be/AvkbhFmJcn4

      He can get your browser to launch an arbitrary application on your PC when you open a webpage.

      • Nope. That did not show that. Just the opposite. He had a browser up, clicks on what appears to be a .doc, which simply creates a tab. However, I did not see the browser exec an app.
        • So putty opened all by itself, right?

            The word document, which was already on his local system, which is already preset to trusted which can execute macros, executed putty.

            • I thought so as well, but just ran the video again. Just dawned on me that he restarts the web page and putty comes up.
              Well, this guy MAY actually have something.
              • Well, this guy MAY actually have something.

                Or maybe the page has a hidden image loaded from a webserver running on localhost. The webserver is configured to start putty when someone connects...

                I did something like that 15+ years ago, so it's nothing new at all.

                • Correct. That is possible. However, why do that for the publicity? That is SUCH negative publicity that he would never work in software again.

      LMAO

      The very first video where he purportedly shows an Office 2010 0-day vulnerability ("it has silent and automatically download function"), I noticed he right clicked the desktop and clicked pressed "refresh"...
      He then moves on to show that he really is running Office 2010, and then he opens a link, not a word file, which opens MS Word and then opens a local, not silently downloaded, executable: Putty. He finishes by typing "1337" in the connectbox of Putty.

      There are unthinkably many scenarios that lead to this behavior, but this dude having been able to find an actual 0-day vulnerability in any software is not one of them.

      • and then he opens a link, not a word file

        How can you tell it's a link (and what do you mean by "link" - shortcut? URL file?) and not a Word file? The filename of whatever he clicks on (which admittedly doesn't look like any Word .doc icon I've seen, but I don't see very many) does seem to match the filename showing in the titlebar of the opened Word window.

        Not that I don't believe this guy really is clueless.

        • If you look closely sometimes you see the little icon that designates a shortcut. I don't know why it isn't visible all the time, may have something to do with the recorder he used. Also look at some of his other video's, he basically does the exact same thing everytime.

          He could have bound a keyboard shortcut to open Putty for all we know, and he just times pressing the combination to "prove" he has an exploit. Kinda stupid that he never ever gives the source for his exploits, maybe he's just furious that h

          • If you look closely sometimes you see the little icon that designates a shortcut.

            Oh, I see what you mean now - I think you've mistaken the optional Windows item selection checkbox for a shortcut indicator.

            http://www.sevenforums.com/tutorials/10111-select-items-check-boxes.html

            But yes, you're right, that video is proof of nothing.

            • Oh right, anyway it would still be anything, like a batch script of which he changed the icon or whatever.

          Your point being?

          But apples vs. oranges anyway. I don't know Ucha Gobejishvili's middle name (if he even has one), else I might have upped the minimum number, if I hadn't been completely joking... Though 7 vowels in just a first+last name seems excessive; I blame his parents.

          • if I hadn't been completely joking

            For me, it was just a fun thought exercise to see how your heuristic held up against real-world American names or otherwise plausible anglophone names like Stephanie Peterson: eaieeeo (7).

            Though 7 vowels in just a first+last name seems excessive; I blame his parents.

            For one thing, different languages have different standards for a last name. Russian, for example, has lots of surnames that carry the suffix "-ov" (fem. "-ova"), "-ev" (fem. "-eva") or "-in" (fem. "-ina"). Greek has the suffix "-opoulos", which corresponds to English "-son" but has four vowels by itself. I just wanted to
