OK, so Ram PM'd me on this, saying my message board was hacked. Here's our conversation:
I had the chanchoi URL edited to prevent infections; according to Norton SafeWeb, the site originated from Moldova, using a Chinese domain. The redirect script was obfuscated (read: masked); it made an invisible frame on the HTML file, which redirects to the script. This is an example of a drive-by download, in which exploits, or holes in the security of an application, are being taken advantage of in infecting users with malware.
I'm planning on some security measures on the site, such as a password change. Any thoughts on this?
