usally I don't disclose any information about the security vulnerabilities that I find.
But in this case, I have to.
First, I won't give any information about the security vulnerability!
The vulnerability itself could only be programmed by a total noob.
There isn't any information about the owner of the site.
There site doesn't provides no contact information.
The whois returned only a postbox.
Total scammer, tries to lure as many users as he can trough the so called "beta invitation".
Once the "beta" has started, most of the "lucky" ones will download an random_file_name.exe,
which installs a trojan and/or uploads the wallet.dat on the victims pc.
I strongly suggest to not register to that beta and don't download software from it,
until, it still could be, proved otherwise.
a nice guy
