Symantec has taken down a significant part of the ZeroAccess botnet, by exploiting a weakness discovered in its code. The botnet is a virtual money machine, as the primary focus is Bitcoin mining and click-fraud. ZeroAccess spreads via exploit kits, usually after victims follow a link in email or downloaded pirated software or Warez (key generators or software cracks) In tests, it took an average of just five minutes of P2P communication before another bot was sinkholed and removed.”]
