Matthew GarrettIt's been the sort of day where I discover that I have a surprisingly useful ability to intuit fields in headers that are probably uuids and figure out what this structure is as a result
Did you know that you can impress people by just pasting some bytes into github search and then saying "Ah yes that's an EFI-spec RSA2048-SHA256 signature" (you do not need to do the github bit in front of them)
Anyway simply mechanically copying potentially interesting looking sequences of bytes into search engines is an incredibly underrated part of reverse engineering work
Sven "DrMcCoy" Hesse@mjg59 also useful when reversing older games. someone might have already written modding tools for the game or one from the same dev team that uses the same file formats. Or it's not even a wholly unique format, but just an obscure one. Or maybe it's a sample format in the AdLib SDK, happened to me
