So... anyone willing to learn enough about BitCoin to build something to find all the "fixed" transactions? It shouldn't take much analysis to determine whether or not MtGox has been drained.

All these articles written about what happened but no one able to just look at the blockchain and give hard numbers.

Do we actually have an exhaustive list of wallets controlled by Mt Gox though? That would seem like difficult to obtain and likely proprietary info they would not want to reveal.

my understanding is that the TxID is a sha256 of the entire transaction, hence it would be feasibly and even rather simple to scan the blockchain for invalid transaction IDs.. however we would have no idea which ones could be attributed to mtgox

I don't think you could accurately estimate by looking at just the blockchain.
