Bots are the root cause of many security problems on the Internet, as they send spam, steal information from infected machines, and perform distributed denial-of-service attacks. Many approaches to bot detection have been proposed, but they either rely on end-host installations, or, if they operate on network traffic, require deep packet inspection for signature matching. In this paper, the authors present BOTFINDER, a novel system that detects infected hosts in a network using only high-level properties of the bot's network traffic. BOTFINDER does not rely on content analysis.
