Direct Connect Used For DDoS Attacks
As the protocol allow hubs to redirect users to another hub, malicious hubs have redirected users to other places than real Direct Connect hubs, effectively causing a Distributed Denial of Service attack. As well, the hubs may alter the IP in client to client connections, pointing to a potential victim.
The CTM Exploit made its presence known during 2006-2007; it made the developers take security issues more seriously since the whole direct connect network suffered from DDoS attacks from this exploit. It's recommended for users to run later versions of the hub software due to this exploit. Many hublists have started to block insecure hubs.
As of February 2009, an extension for clients was proposed in order for the attacked party to find out the hub sending the connecting users.
