Abstract

In August 2013, the Tor network experienced a sudden, drastic reduction in performance due to the Mevade/Sefnit botnet. This botnet ran its command and control server as a Tor hidden service, so that all infected nodes contacted the command and control through Tor. In this paper, we consider several protocol changes to protect Tor against future incidents of this nature, describing the research challenges that must be solved in order to evaluate and deploy each of these methods. In particular, we consider four technical approaches: resource-based throttling, guard node throttling, reuse of failed partial circuits, and hidden service circuit isolation.
