The number of client-side attacks has grown significantly in the past few years shifting focus on poorly protected vulnerable clients. Just as the most known honeypot technologies enable research into server-side attacks, honeyclients allow the study of client-side attacks.

A complement to honeypots, a honeyclient is a tool designed to mimic the behavior of a user-driven network client application, such as a web browser, and be exploited by an attacker's content.

Thug is a Python low-interaction honeyclient aimed at mimicking the behavior of a web browser in order to detect and emulate malicious contents.
