Spray / mem pattern visualizer. Heappie!
Is an exploit-writing-oriented memory analysis tool. It assists vulnerability researchers in tracking heap sprays (as well as other memory patterns) by providing visualization of the memory state. VERA - Cyber Security Research. Heaper.py at master from mrmee/heaper - GitHub. Si - Visualizing entropy in binary files. Last week, I wrote about visualizing binary files using space-filling curves, a technique I use when I need to get a quick overview of the broad structure of a file.
Today, I'll show you an elaboration of the same basic idea - still based on space-filling curves, but this time using a colour function that measures local entropy. Before I get to the details, let's quickly talk about the motivation for a visualization like this.
