reverse engineer binary encoded data










0















Is there a general approach? It doesn't appear to be encrypted, and I know the file must contain numeric tabular data of some kind:




$ od -tc filename.hobo | head
0000000 H O B O 210 r 004 001 d 210 035 004
0000020 001 c 210 " 035 001 001 035 q - $ 070
0000040 8 E 001 d 377 377 235 220 001 v f
0000060 030 002 210 5 032 001 003 003 001 a a

  • If you don't know what actual data is stored there - it would be impossible. If you know - possible with some degree of confidence. If you can alter it - then even with higher confidence.

  • @zerkms I do know at least some of the data (have a CSV export of a table) in the file. Can you point me from "possible with some degree of confidence" to step 1?

  • Yes - if you know original data - simply try to find it in that dump? I'd use xxd though to visualise it
