    Hey guys,
    I think i found something that could be called a very tiny security issue in IE :)
    I need people with AV software installed to test it for me
    Go to: http://www.stormbyte.com/vtest/test.php
    and report :
    a. If your antivirus warned you about a new virus on your system
    b. Your operating system, browser, and antivirus

    Don't worry there will be no viruses or spyware installed. I just found a way to trick some antiviruses into thinking that computer is being infected by just visiting a web site.

    Thanks!

    A - nope
    B - Win2k, Firefox 0.9.1, NOD32

    Just got a blank page there so if it's anything Proxo might have blocked - that might be the case as well.

    Yeah. Firefox is safe. Try with IE :)

    I've got my own doubts about doing that. I used firefox, clicked on the link, and got a blank page with absolutely nothing happening at all.
    I used IE, and also I get a blank page with nothing happening at all. I'm very secure here.

    Same result - IE 6.0 - also routing through Proxo. I'll try without.

    Same in IE without Proxo.

    Then NOD32 is not looking at it as a virus.
    But when you scan cookies folder you should find "Eicar" virus.
    Unless Nod does not scan txt's or you have cookies disabled.
    Oh well. Thanks anyway.

    I get this in Proxo's (+ Opera) log window. Ran it with IE, no proxy, and F-Prot 3.16a and got just a blank window and no alert.

    That is way I needed more people to test my idea:)
    Basically, when you go to that page your browser will receive a cookie.
    This cookies has eicar test virus string as a value. Some AVs when they see this file being written to the hard drive will inform you about that.
    It will not work if you use Firefox, or have cookies disabled, or your AV is not scanning TCP packets, or txt/cookie files.
    Like I said this is not a big issue, (or in your case it's not an issue) but I had to check it.

    How did F-Prot do realtime? Or did you try that?

    So it works:)
    Now I have a question. Do you guys think that this could be called a "security hole" in IE? I know that it's only a cookie, can't be executed and so on, but still it could cause problems for some people. (OMG! My computer is infected - for example)

    Virus test file. I did not wanted to use string from a real virus so I had to use Eicar. YOu can read more about it here:

    :) I know. I tested it first with mks_vir.
    Question remains: should this be reported somewhere or not? ;)

    It would seem to me that it warrants attention to try and prevent future exploitation.

    You won't get any alert if you block stormbyte's cookies. The cookies will cause your antivirus to alert you if allow them in.
