Test your computer/browser protection to the WMF exploit


Synapse

Recommended Posts

found this quite fun... its in german... but just scroll down to where it says "Test"

http://www.heise.de/security/dienste/brows...os/ie/wmf.shtml

My results:

Firefox: Asked me to download it or open it.. i chose to download it and double clicked the icon to open windows fax and picture viewer.. calc.exe ran and explorer.exe crashed.. even right clicking and hitting properties on the file caused it to run.

IE: Started download, ran windows fax viewer thing but no calculator execution... which i found weird.. maybe its reading from the cache, i'll have to test after i do a restart and clear my browser cache.

Explorer: with Thumbnails turned on, it ran calc.exe and caused the explorer.exe to crash again.

Post your results..

btw.. incase anyone is interested on how this looks when the actual infected .wmf is ran.. check out this movie

IE: Asked me to download or open it. Chose Open: "Open file with..." dialog comes up. I choose to open it with IE. The "save" dialog comes up and closes immediately.

Chose Save: Downloaded the WMF. Double-clicked it and "open file with..." comes up again.

Right-click and view Properties: Standard property page comes up, nothing else happens.

Turned on Thumbnails: Nothing happened.

Tried various Image-editing programs I had. All of them refused to open the file, claiming the file was invalid.

I guess I'm immune... :thumbup

OS: 98se customised.

it's a TEST wmf file.. all it does is runs calc.exe if your system is vulnerable..

and yes i have checked this link myself, both on a VMware workstation and my main computer.. with regmon, filemon, and process explorer all running.. to make sure its 100% safe.. I would never put up a link here that could even have the possibility of damaging a fellow MSFN users comp in anyway.

as for the site being in german, its a german magazine.. basically an equivelent of slashdot.. they made it so people could check to make sure they were protected from the exploit without having to run the actual destructive wmf.

kthanks.

My results:

Opera and IE: Asked me to download it or open it.. i choose to download it and double clicked the icon to open windows fax and picture viewer. Viewer opens with the message: No example aviable (translated from dutch to english). And yes, i have the WMFpatch installed from microsoft...

But nice movie, now i know how it looks. Thanks! :)

FF prompts to download.

saved file and scanned and, naturally, ClamWin detected:

\browsercheck.tif: Exploit.WMF.Gen-3 FOUND

opened file and got error "format of the file could not be determined". however, i don't have windows p&f viewer installed. 'tif' is associated with XnView, but it obviously wasn't a valid 'tif' file.

calc.exe didn't run.
