Didn't mean to have you apologize, it did it's job. It showed
That I was not vulnerable. I just found it interesting that my
AV called it something that could not be found through search.

thank you

<|>It might be detected as Trojan.Moo or any other variant of 
<|>the JPEG exploit. As I said, it attempts to exploit the 
<|>system to see if it's vulnerable, using an "infected" JPG. 
<|>The file I provided is simply a SFX with a batch file and 
<|>the "infecte" JPG (named exploit.bak). No attempt has been 
<|>made at all to mask what's inside.
<|>
<|>I figured those that would want to use it would either not 
<|>worry about the virus warnings, or not get them at all and 
<|>REALLY need the fix it helps provide. =) Email me at the 
<|>address provided in my original email (exploit _AT_ guidoz 
<|>_DOT_ com) and I'll provide a link to the batch files and 
<|>such so you may modify them as you wish.
<|>
<|>Sorry for any confusion with the AV. I should of warned 
<|>about that in the original email. (Others have written me 
<|>asking the same question.) I only provided it to possibly 
<|>help others who have lots of friends asking them for help to 
<|>patch their systems. This simply sees if they are 
<|>vulnerable, then leads them through the steps to patch the 
<|>system if they are. (You may have to tell them to ignore AV 
<|>warnings, or disable the AV scanner. Again, I urge you to 
<|>test this on a NON-PRODUCTION machine first. See what it 
<|>contains, read the batch files, see what it downloads, etc.)
<|>
<|>Please feel free to ask me any questions. Hope it helps someone else.

<|>Peace. ~G

<|>> <|> <|>Hello list, <|> <|>I wrote a very simple program/batch file

<|>> instructions on how to patch the <|>exploit. It has been 
<|>tested on my 
<|>> own lil happy lab network, as well <|>as one one network 
<|>where I'm a 
<|>> sysadmin. (Tested on Windows XP Home <|>and Pro, SP1a and 
<|>SP2.) <|> 
<|>> <|>It DOES test for the exploit by attempting to use an 
<|>"infected" JPG 
<|>> <|>which downloads the instructions for fixing it, if 
<|>exploited. By 
<|>> <|>viewing the strings in the JPG, you can see the file it 
<|>downloads 
<|>> and <|>check it out for yourself. It's clean. =) Just 
<|>contains a batch 
<|>> file <|>and a program to launch the batch file. (The file 
<|>that gets 
<|>> <|>downloaded <|>is a simple SFX.) Links are below. It contains a 
<|>> warning saying it's <|>about to try to exploit the system 
<|>and to save 
<|>> data in open programs.
<|>> <|>(It also warns that Explorer may crash.) <|> <|>I wrote 
<|>this merely 
<|>> to save myself time and allow friends/family to <|>test their own 
<|>> systems, then patch them without having to call me for 
<|><|>help. It's 
<|>> not been tested in every environment and in every <|>scenario.
<|>> <|>If you find a problem, feel free to email me (exploit 
<|>_AT_ guidoz 
<|>> <|>_DOT_ com) Obviously I'm not responsible if it's abused 
<|><|>somehow,

<|>> <|>
