Enterprise-targeted botnets tend to be a different breed make use of enterprise-specific functionality (e.g. being proxy aware and exploiting vulnerabilities over the network that would be blocked by perimeter firewalls) Taterf is a run-of-the-mill botnet focused upon stealing online gaming credentials (such as log-in credentials for World of Warcraft, EverQuest and Aion) From there they infect files and additional hosts, but achieving very little apart from leaving behind a trail of breached assets.
