Vulnerability Development: Re: Infected jpeg files? (viruses)

[Jonathas Diogenes Castello Branco <jonathas () lia ufc br>]

I think it's possible to create a virus that infects win32 binaries that
contains images. Part of the code would be on the executable area, and the
other part could be in a Icon image. This would make easier for larger
viruses to hide themselves in an bigger executable file.
