I have a client SBS 2003 server who had their IIS hacked.

All websites on IIS have been redirected to :

http://0xcfe190c7/ks/?http://www.commbank.com.au/personal/survey/default.aspx

Currently I've disabled ports 80 and 443 to the server via their firewall appliance, but I'm not sure where to start on re-setting it and securing it afterwords

I"ve requested all users scan their systems for viruses and we're changing all the passwords.

Thanks in advance!

Do you have backups of these websites?  If so, your best and quickest option is to delete those websites and create new websites, and restore those websites.

Never put you websites in the default location of C:\Inetpub\wwwroot always change that location, never use the IUSR_computername account as your account for anonymous access, change it!  Never install all you websites on a single website, with the same IP address or the same IP address of the server.

Goodluck!

Are you familiar with SBS server?  The sites that were hacked (really IIS was hacked) were the companywbsite and OWA, I've never had to move those before.   I almost suspect that someone's weak password was cracked.

Passwords are generally cracked from compromised client PCs and also specially Password sved browser like mozilla has done this manytimes....

Compell your users to use strong passwords and no easy passwords..set GP for strong pwds..ask them not to mark password remember in browsers

Use S/W firewall in server like Visneic that has saved us many many times from hackers and intruders and from DDOS attack.

Update AV scanners in server and scn for virus.

Check "cmd"  in c: driveif any user or group has access that must not have access on the same

1. Use Good S/W firewall
2. Use and update Virus scanners in server and scan server compltly.
3. Update security patches of MS if left any in updates
4. Use and force your clients to change and use only strong passwords.
5. Do not give access to any IUSR or client groups on CMD in server.
6. Disable Webdev if not used in server.
7. Check sites and isolate that has scripts and executables enabled and check zip files in client drive if they have any strange exe files which are infected .
8. check if any CSS files are compromised and code injected as they are prime way to deface sites.

Block unused and unwanted ports in server.
