I think the point were CR/LF in the filename ... this way TB! did not show the
last extension ... But don't nail me on this ... it's only from my remeberance
:-)))

 What are your thoughts on this?

What do you mean by a TB! virus warning Jan? If I include *.JPG under
Options/Preferences/Warnings/Always Display Warnings... Then whenever I
attempt to open such a file, TB! indeed warns me about the possibility
this particular file might contain a virus.

Are you referring to something different?

I have not read this. Do you have a URL? *.jpg and *.jpeg files are
just pictures with no executable code. Since you refer to a beta
version (not allowed on this list ;-)), you can disable any file
types under the new menu item Options / Preferences, if you want.

If you use the virus-friendly Microsoft® products, a file called
virus.jpg.pif or virus.jpg.vbs will by default be conveniently (for
virus-spreaders) shown as if it were called virus.jpg - I think this
is what was meant in the article you thought you read.

rant

Microsoft® calls this deception user-friendly. That must make us
believe that their most important users are the people who want to
spread viruses. I don't know why Microsoft® is allowed to continue
distributing virus-friendly and home-user-unfriendly products. Do they
know people in high places?

I may be wrong, but even as a technical there is no space on my imagination
for Image-viri as I've NEVER seen any (not proprietary) image-format that
contains executable code. So without executable code viri are impossible.
What I cannot deny in general the the hypothetical possibility of viri in .psd
or something else, because I don't know if there are informations stored in
them formats that could contains executable code.

AFAIR there also was a Bug in Netscape = 4.76 where a .gif image could
contain javascript because of a bufferoverflow of Netscape, but this was not a
.giv-virus as more a Netscape virus (and the hidden code was limited to
JavaScript!!!)

Hi Jan,

On 03 June 2001 at  12:29:13 -0400 (which was 17:29 where I live)  Jan
Rifkinson wrote to TBUDL and made these points:

That this is a confused report about the attack which involved a file
name x.jpg.scr, where the double extension was supposed to mask
the fact that the file was a trojan script and not the innocent jpg it
seemed to be. Early versions of TB could be fooled by this under some
circumstance (I can't recall exactly what they were), but that
loophole has long been plugged.
