The hacker is obviously one of the best hackers ever. It's only going to get worse and worse, duh, and there is nothing you can do about it! That's why you should hate hackers. Hackers ruin our country. Hackers. Hackers. Blah, blah, blah.
Shut up, will you? I'm sick of people using the word "hacker" is such false ways. You're making your self sound like a complete idiot. Learn how to read your own logs. Look through the HTTP requests your web server recieved to get a better understanding of what exactly happened. As long as your running the current release of SMF, no, there aren't going to be any huge security holes (discluding zero-days).
Yeah, sure. I'll take an FTP account. I could use one for my warez. </sarcasim>.
