Conficker worm authors could launch DDoS attacks

Share this article:

Prolexic Technologies has enhanced its global network defence systems to protect against possible Conficker distributed denial-of-service (DDoS) attacks.

 

Prolexic's chief technology officer Paul Sop claimed that the general approach to Conficker, and other viruses designed to wreak havoc on compromised PCs, has been to address these at the source by updating virus scanning and PC protection software in order to disinfect compromised PCs.

 

However he claimed that there is a threat to externally targeted businesses and networks, and attacks can be launched simultaneously from millions of PCs, similar to a DDoS attack.

 

Sop said: “Conficker's DDoS capabilities are a side-effect of its proliferation and update capabilities. However, Conficker's author(s) could weaponise this botnet at any time and launch massive DDoS attacks.

 

“We've recently seen the number of domains that Conficker can attack in a day grow from 250 to 50,000, and Prolexic has taken the necessary steps to protect its customers from the potential damage that could occur should one of the targeted domains be theirs.”

 

Prolexic further claimed that the recent Conficker updates are expected to make it more difficult for anti-virus specialists and others to block the domains used in attacks.
