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.

Famous quotes containing the words direct, connect and/or attacks:
“The most passionate, consistent, extreme and implacable enemy of the Enlightenment and ... all forms of rationalism ... was Johann Georg Hamann. His influence, direct and indirect, upon the romantic revolt against universalism and scientific method ... was considerable and perhaps crucial.”
—Isaiah Berlin (b. 1909)
“Our father presents an optional set of rhythms and responses for us to connect to. As a second home base, he makes it safer to roam. With him as an ally—a love—it is safer, too, to show that we’re mad when we’re mad at our mother. We can hate and not be abandoned, hate and still love.”
—Judith Viorst (20th century)
“Leadership does not always wear the harness of compromise. Once and again one of those great influences which we call a Cause arises in the midst of a nation. Men of strenuous minds and high ideals come forward.... The attacks they sustain are more cruel than the collision of arms.... Friends desert and despise them.... They stand alone and oftentimes are made bitter by their isolation.... They are doing nothing less than defy public opinion, and shall they convert it by blows. Yes.”
—Woodrow Wilson (1856–1924)
