You guys are late to the party.
MtGox's whole user database was compromised.
Since the database has been leaked I will prove it to you:
steve3, you are the customer #52107
Your password hash: !$1$7u9tG3ex$KkKOgkgdJTknIARmG3SBS1
The password has been hashed with FreeBSD salted MD5. It is a tough cookie but not unbreakable.
The salting prevents time-memory trade off (Rainbow Tables), so a dedicated cracker should crack every each one of them individually.
As long as your password is complex and long enough, it will resist cracking by bruteforcing.
Interestingly it seems that your account steve3 were locked back then.
Cheers,
So it is locked, not stolen? How I can check if this password hash = to my password? Is there any online resource to get this type of hash from my password? If it is locked - at least money should be there and I have slight chance.. But when I tried claims.mtgox.com they just told that password incorrect, which I am sure I did correct.
