As a thank you to those who nominated me for the European Security Bloggers Awards, I’m going to release some new scripts this week. Here’s the second one.
fuzzer.1sc is a 010 Editor script that implements a simple fuzzer. It overwrites bytes in a file or selection. A selection is particularly useful combined with a template. For example, with a couple of clicks you can fuzz the control structures of a JPEG image.
4 parameters (number of fuzz sequences to overwrite, minimum length and maximum length of a sequence, and the fuzz character) allow you to control the random overwriting process.
