This guy ianbeal is horrible, he can hack into your minecraft account and take over your server.
He took over my account (Omega12, I am the owner) and my friend's account.

everyone on the server was told to change their passwords. Heads up for all of you admins.
Changing passwords won't do anything, I had the same guy on a server I hang around yesterday and he ended up explaining what the issue is, where the exploit lies in the source and demonstrating user impersonation.
Since I'd rather not spread it around and have a lot of servers destroyed, I'll just say verify names doesn't actually do anything for the most part. This isn't spread in the slightest so just don't be an asshole to random people who join maybe?
Edit: I should clarify this is only an issue within MinerCPP.
