I'm reversing an application with IDA. My VM crashed and left the IDA database in a corrupted unpacked state.
The next time I tried to load it back, IDA gave me the following error message:
The input database is corrupted: CRC32 mistmatch. Continue? a few times, then it quit with the error
bTree error: index file is bad. Google-ing these error messages gave no useful results, which is unusual.
I'ld like restore the database, or at least extract the data somehow.
I've already tried the following:
- Zynamics bindiff (couldn't open the IDB, said it's probably opened in another IDA instance, which I guess Is a result of the corrupted data)
- Manual hex diff - I just can't interpret the output.
At this point I'm thinking of somehow parsing the IDB and then diffing that output manually.
So, how can I parse/extract data from IDB files?
firstname.lastname@example.org. Otherwise you can use the SDK and the IDA book to figure out the details of the IDB format and extract what details you can salvage.
