We are using dotnetnuke Version 3.2.0
When tring to access one of our portals, the portal page displays for a few seconds and then site visitors are redirected to another site (http://by-nasah.blogspot.com/). Only one portal is affected so far but I am assuming others can be compromised as well.
 
Any advice on how to fix this? I checked the default.aspx page for that portal and all seems normal.
 
We want to upgrade to the latest version of DNN but currently have no technical staff to do this. Is there a migration tool we can use?

Thanks!

check for index.htm or default.htm in your root directory and delete it.

For further assistance contact security@dotnetnuke.com

The OP did say that their portal page shows for a few seconds so it's unlikely to be a hi-jack of default.htm et al.

DNN is its own upgrade tool.  You would be wise to backup the site plus database BEFORE upgrading.  I think there is no guarantee that upgrading will fix the hack.  It may do so, it may not.

Can you log into the portal?  If so, set modules to admin view only until the redirect stops when running as unauthenticated.  The content of the last module is what is the problem.  Also check for redirects in the web.config file.  If all else fails, restore from a good backup, then upgrade.

Are there any modules that users can post content to? This may be a simple as someone was able to upload some javascript that is doing the redirect. It would look something like the javascript time delay section on this page: http://www.tizag.com/javascriptT/javascriptredirect.php
