When talking about security, one of the easiest examples to show is something with [wikipedia:SQL Injection]. It's so easy, that most people laugh at these examples, because no one ever uses this anymore.
It seems, not everyone is aware of SQL Injection yet... The site of the RIAA got hacked a few days ago. As far as I know, one of the first reports were on TorrentFreak. They also have some screenshots of it, like the one below.
We experienced some serious problems since almost 20 hours ago or so. Our host wasn't able to fix the problems instantly and that's why it took so long for BloggingAbout.NET to be in the air again.
Hopefully everything's solved now. We're really sorry for the inconvenience.
