Barcajax, It depends on whether or not you are just trying to hide a file in a jpg, or actually have it execute disguised as a jpg. The latter I don't know how to do, but if you just want to embed an executable in an image file, you could use something like Forensic Toolkit or even the freeware Autopsy which comes with most live security distros. Even Hex Workshop will allow you to do this but you've got to embed it in the right place so that the image will still display, while covering up the existence of the executable. Typically you would need to place it at the end of the image file. If you place it after the image header, portions of the image will appear corrupt or not display at all Hope this makes sense to you... --Jason Kratzer On 10 Aug 2006 13:58:34 -0000, barcajax () gmail com < barcajax () gmail com> wrote:
I came across an article that introduced the concept of using packer software to hide an executable file in another file such as a jpg file. I want to try this out but am worried about downloading malicious files disguised as packers. Can anyone recommend a legit/safe packer that I can use for my testing purpose? Thanks. ------------------------------------------------------------------------------ This List Sponsored by: Cenzic Concerned about Web Application Security?
