[Question] BinDiff users

[tomer121233]

How much time does the diff part usually take you? I'v been waiting for an hour+.

Dump/Load/Rebase => ~45 minutes
Diff/Import => 1.5+ hours usually 😂

Diff/import takes for me around 30mins dump/load/rebase 15mins but when i'm diffing i can not touch ida pro! Sometimes i accidently click on the GUI and ida just freezes and nothing will ever happen...

Ahhh shoot. thanks for the reply.
Took me 3~ h to finish :\

Would anyone care to share how they work with BinDiff? Any articles? I couldn't find anything about it with my searches. Very curious to learn!

It depends what you mean? My ideal is that I start with a good known binary that I've already labelled in ida. Once you have that, you can use that as your base to compare all new patches to. Once you've confirmed that the functions that have been diffed are a good match, you can also confirm them to bring your base forward in the patch version.

Does it last well through patches? For example, if they change an internal call chain, that breaks the flow and I would think BinDiff wouldn't be able to match that signature anymore?

Works fine however going from classic to BC to Wotlk some sigs are gonna break finding them is easy tho if you use your old .idb for reference...
