+The Tor Project makes use of the Python tool <a
+href="https://gitweb.torproject.org/user/phw/exitmap.git/">Exitmap</a> to
+systematically scan for malicious and misbehaving exit relays.  Once such a
+relay is found, it is assigned the BadExit flag which prevents clients from
+selecting the relay as last hop in their circuit.
+    </p>
+
+    <p>
+Exitmap supports scanning modules which implement a specific scan over
+exit relays.  Examples are the DNS module which checks for DNS poisoning
+or the patching check module which looks out for tampered file
+downloads.
+    </p>
+
+    <p>
+This project is meant to extend exitmap in several ways.  First, it
+should be made fully autonomous.  That means that exitmap should be able
+to run in the background, periodically fetch new relay descriptors, and
+have a smart algorithm which keeps scanning all exit relays
+periodically.  Second, exitmap should be able to emulate some user
+interaction and dynamically "explore" the web in order to detect
+tampering.  Third, unit tests should be added for existing and new code
+in order to make the code base more robust.
