Have the forums been hacked?

And is it just the forums or also the main page?

It's only the forums, not the main page. Anyways, the site should be taken offline until it's fixed, otherwise lots of people will be hacked. Also, and obviously, web pages don't just change themselves...

Lucky I am on my Mac! God this could be dangerous (I don't even have anti-virus for my non-internet connected laptop - I don't connect it to the internet so n most cases it doesn't matter). There isn't anything at http://zchxsikpgz.biz/. It is just the default Apache filler page! This is really bad. I hope it can be squashed soon.

When the HTML entities are decoded (" ;"), it is http://zchxsikpgz.biz/dl/adv543.php

Didn't affect Firefox, had to fire up IE7 Beta 3 to see it, and NOD32 stopped it.

I can confirm: Invision Power Board has been hacked.

That happened also tmy forum at http://forum.wininizio.it

Useful notice for the admins: grep your server for the string "r57shell".

The hacker that attacked our website used this perl script: http://www.milw0rm.com/exploits/1720

The script attacks IPB up to v 2.1.5 but it could be improved to attack 2.1.6 also. The perl script can be locally executed (you just need a Perl environment in your system): it adds a post with a user account specifically added to begin the attack; the script then adds a new post with strange characters and finally it enables a remote shell. The hacker that attacked us placed a WGET command to upload a web shell (r57shell.php) that gives full control over the server, so he was able to modify the index.php file of any web application he found on our server.

Additional info: this kind of attack uses the Invision folders that need to be chmod 0777 like /uploads or similar.
