We have been receiving a massive amount of errors in our event logs pertaining to 404 errors.  It looks like some sort of attack, has anyone else experienced similar issues?  Here is a copy of one the errors:

TabId:

PortalAlias:

OriginalUrl:/announce.php?info_hash=%DA%3A%90%2F%22%1E%C3u3%DB%3A%14r%1C%09%0C%9F%E4%CA%EE&peer_id=%2DSD0100%2D%05%B6%B0%2E%FF8%AC%184%8FJ%1D&ip=175.148.112.36&port=8478&uploaded=1467764919&downloaded=1467764919&left=241481&numwant=200&key=17356&compact=1

Url:http://a.tracker.thepiratebay.org/404.aspx?404;http://a.tracker.thepiratebay.org:80/announce.php?info_hash=%DA%3A%90%2F%22%1E%C3u3%DB%3A%14r%1C%09%0C%9F%E4%CA%EE&peer_id=%2DSD0100%2D%05%B6%B0%2E%FF8%AC%184%8FJ%1D&ip=175.148.112.36&port=8478&uploaded=1467764919&downloaded=1467764919&left=241481&numwant=200&key=17356&compact=1

UserAgent:Bittorrent

HostAddress:113.230.17.31

HostName:113.230.17.31

Server Name: DNN311

 

The errors are mostly identical besides the HostAddress, UserAgent andOriginalUrl changes.

 

Any help on this would be appreciated!!

Yes that looks like a distributed bit torrent attack - someone has published your site as an announcer for a bitorrent file
- i would suggest you talk with your hosting provider about url mapping or blocking calls to /announce.php.
If your hosting supports urlrewrite - you can do it yourself in the web.config as well.
