The third largest botnet in existence, Grum, has been taken offline by authorities. The cooperative, collaborative effort involved in this multi-national sting is impressive in its own right. Don’t expect spam to suddenly stop, but don’t expect a new botnet. The attackers are still out there as well, so they may attempt to grow a new Botnet. Users should make sure they have good antivirus software installed and kept up to date. They should be proactive about keeping their systems and applications patched with the latest security updates.”]
