I just downloaded a 50-cent track intentionally to receive fakes or to check on hash exploiting.. almost straight away..
206.62.151.21.mp3 was corrupt (The downloads are named after their IP with the thing I'm developing).
The beginning is fine but then it's corrupt. This is one of 'those' files and even better.. 206.62.151.21 belongs to NHI Networks which PG is already blocking - with just one attempt on one song, I've managed to uncover at least one faker for sure.
I'm guessing kazaa's hashing is based on filesize, type and a block of data at the beginning of the file.(well, for mp3s anyway, ISOs etc are probably different)
Anyway.. I'm working on it. Things are looking pretty good so far. Just thought I'd let you all know what I'm up to... oh.. and props to Random Nut for the idea.
Peace!
