Hi malware fighters,

Do this on your own risk, test out the crashability of your favourite browser with BrowserFry:

Hey Polonus, do you have a similar banner to other nations too? :wink:
I’ve tried to crash my own browser (for what ???) but I can’t realize how to use your kindly link ::slight_smile:

One for you on page 11, http://www.userbars.be/category/countries/11 and page 12.

Hi folks,

Yep, good thing you found the link to the banners, there is one for every nation…
Then about the other link, just paste some code in the upper window, run and you see how your browser reacts in the bottom one. I think this is not your kettle of fish, when you aren’t a pen tester, or like to test exploit code inside a browser, all very educational.
An example test with the following sample code in the upper window:

<body onLoad="alert(window.frames.iframe.document.getElementsByTagName('body')[0].innerHTML);
alert(window.frames.iframe.document.cookie);">
<p>test</p><iframe src="http://www.amazon.co.uk/" id="iframe" name="iframe"></iframe> 
</body><code></code>

This does not crash your browser, but you see the workings of an i-frame redirection (harmless example)
But opening the following inside IE7

<style>*{position:relative}</style><table><input /></table>

brings this browser in an infintive loop and down…IE7 killed with 6 words… while Firefox stands.
