Patching: Binary Ninja Basics ep.3

Ғылым және технология

One of Binary Ninja's strengths is the many ways you can patch binaries. Even if you're an expert there's probably some ways you might not know about.
Small update: early in the video Jordan mentions copying the physical offset using a snippet, but that's been added to the built-in copy menu in the bottom-right which makes navigating between views even faster and easier!

    I may need to wire up Python because I’m not seeing much on patching involving variable reassignment or replacement of one call with another. I’m very spoiled by supra-assembly languages.

    How to export the patched binary, or show differences I made so far to the input file?

    im also interested in this feature. I have to keep patching every time I run the binary inside bin ninja it's annoying, I'd like to patch only ONCE

    My first time trying to use the c-compiler I'm working on a crackme and want to printf debug something. I copy the pseudo-c and make sure it's valid c. I add a printf before the return and I compile. What I get is just an error saying: "[Compilation Failed] stdin:1: error: syntax error" I imagine there are probably some limitations I need to know about that weren't covered here.

    Hard to know without more context -- what's the exact snippet of code you're trying to compile? Also, YT comments aren't a great way to get support, I'd recommend joining our public slack (slack.binary.ninja/) or getting in touch with us via twitter or email.
