Browser Security Test
http://bcheck.scanit.be/bcheck/

Allows users to subject their computer/browser to a selection of
synthetic exploits as follows:

- user selectable tests / exploits
- test only exploits known to affect the user's particular browser
- all tests for all known exploits

There are 19 tests in total. See below for a summary of them.

I ran these tests 3 times - once against each of the installed browsers
on my win-98se system.

I did not have any AV program or any form of browser-protection program
running on my test system.

Test results
-------------

Browser name: Firefox/2.0.0.12 Navigator
Version: 9.0.0.6
Platform: Windows 98
Congratulations! The test has found no vulnerabilities in your browser!

Browser name: Firefox
Version: 2.0.0.20
Platform: Windows 98
Congratulations! The test has found no vulnerabilities in your browser!

Browser name: MSIE
Version: 6.0
Platform: Windows 98
Congratulations! The test has found no vulnerabilities in your browser!

During the IE6 test, I was asked to download / run these two files:

crashy2.xul (a small script file)
path-neg.svg (another small script file)

The second file seems to be a very old IE5/IE6 exploit, as described
here:

http://www.greymagic.com/security/advisories/gm012-ie/

Neither of the above 2 files, when submitted to VirusTotal, are detected
as threats by any of the 42 AV apps hosted on that site.

Meb will no doubt respond to this post by frothing and spewing one
excuse after another why these tests should not be believed or taken as
evidence that Win-98 combined with old/legacy browsers are not
vulnerable to common exploitation.
