Simply i dont think that the Iter count that bitcoin2john gives is a value probability to conclude that the wallet could be fake, the iteration count is simply the number of how many times the password was hashed.
I have the 11.56 BTC wallet and it gives the same iter count from bitcoin2john that You posted, and the wallet was not fake becouse it was opened.
Just want to use different tools on this wallet but I don't have it.
There is nothing wrong with bitcoin2john, did it occur to you that the wallet is a fake one and the actual real person of the wallet just moved out the tokens, only cause the sites that sell it say it is a success story does not mean they're telling you the truth. Have they provided the password with the success story? or just that funds have been moved from it?
It is very unlikely that multiple wallets contain the same iteration. It could but VERY unlikely.
