Symantec sinkholes significant part of massive botnet

Today Symantec announces it has successfully sinkholed a significant part of the ZeroAccess botnet, which has been active since 2011 and is one of the largest known botnets in existence - with upwards of 1.9 million infected computers, generating tens of millions of dollars annually.

Highlights include:

Symantec takes first step in combating the ZeroAccess botnet - Symantec has sinkholed more than half a million bots - making a serious dent to the number of bots under the attacker’s control. Symantec is actively working with ISPs and CERTs worldwide to help get infected machines cleaned up.

ZeroAccess botnet is sophisticated and resilient - ZeroAccess has a highly technical and sophisticated infrastructure - it uses a peer-to-peer architecture giving the botnet a high degree of redundancy with no central command and control server. It also uses various advanced methods to survive on infected machines.

How the attackers are making money through ZeroAccess - ZeroAccess leverages click-fraud and Bitcoin mining to carry out two revenue generating activities - potentially earning tens of millions of USD per year in the process.
