A security firm and ISPs have colluded to take down the command and control servers of the Lethic botnet, according to an article on The Register. Neustar, a security research firm, along with cooperation from ISPs, were able to attack the servers of the Lethic botnet, which was used in distributing spam.
This is the third major assault against spammers by security research firms in the past year. Cyber criminals are quickly adapting and are creating more resilient botnet networks. Cyber criminals are moving to shared models on forums, etc. Several hours following the attack, researchers noted infected computers were searching for new servers to attach to.
The attack against the Lethic botnet will likely only cause a minor disruption in incidents of spam and only for a brief period.
