I made a quick-coded tool to compare 2 files byte per byte : osos's
data are very different (except for the 690 bytes), there are no more
than 2 or 3 adjacent identical bytes.
Same thing for aupd, but only the first 32 data bytes are identical

I guess that Vincent didn't look further than the first bit of
difference in the payload, am I right Vincent ?

Can someone build a tool to detect differences and similarity in two (or
more) binaries ? (and of course perform the frequency analysis of the
xor of the two firmwares as serpilliere mentioned it)
