POSTER: Application-Layer Routing Attacks on Tor

Katharina Kohls, Christina Pöpper

IEEE Symposium on Security & Privacy (Oakland), May 2019


Application layer routing attacks allow to force Tor entry traffic through an area under adversarial control. In contrast to previous routing attacks that focus on layer-three or -four mechanisms, the application-layer attack exploits Tor's DoS mitigation features that were implemented to prevent from bursty connection and circuit establishments. The proposed poster documents the general attack concept and summarizes the results of preliminary experiments. Furthermore, it raises questions about several open challenges and provides an overview of the next steps of this work in progress.
