I've been sans DSL for over a week now, so forgive me for the lack of posts. Using dial-up is almost as bad as having to listen to Clay Aiken on repeat. But anyway...

While I've been away, some nugget has been trying to hijack my contact form. He's done it about 10-15 times over the course of the past few days, and he's easily recognizable by the email address he includes in the attempts, jrubin3546@aol.com.

All it took was a Google search for that address to uncover other victims. That also led me to Form Post Hijacking, a very informative look at what is going on when these hacking attempts are made. Not only is there a very in-depth explanation, but a good description of preventative measures to take as well.

Even though I don't believe the hacker, if you can even call him that, has been successful in exploiting an open relay on my domain, I've gone through and followed the measures explained at Form Post Hijacking anyway, eliminating all carriage returns and line feeds from entries in that form. However, it should be noted that I used PHP's ereg_replace function instead of preg_replace and combined the two calls into one, like so:

$message = ereg_replace("\r|\n", " ", $message);

I'll still probably have to deal with the annoyance of receiving worthless emails for a while, but at least I know that loser isn't getting anything out of it.
