"A good exploit is one that is delivered with style."Stegosploit creates a new way to encode "drive-by" browser exploits and deliver them through image files. These payloads are undetectable using current means. This talk discusses two broad underlying techniques used for image based exploit delivery - Steganography and Polyglots. Drive-by browser exploits are steganographically encoded into JPG and PNG images. The resultant image file is fused with HTML and Javascript decoder code, turning it into an HTML+Image polyglot. The polyglot looks and feels like an image, but is decoded and triggered in a victim's browser when loaded. The Stegosploit Toolkit v0.3, to be released with improvements upon existing v0.2, contains the tools necessary to test image based exploit delivery.
