Vulnerability Development: Re: Infected jpeg files?

["Rob Salmond" <rob.salmond () home com>]

If memory serves, from my days of Mac use you should be able to do a
straight ResEdit on the file who's icon you wish to modify.  Much the same
way you can alter the icon of a win32 binary with similar reshacking
programs.  When the .res file is added during compilation its a standard
.ico file added as static data to the binary.

hope this helps,
