-The Tor exit node scanner 'SoaT', part of the <a
-href="<svnsandbox>torflow/">Torflow project</a>, makes connections out
-of each Tor exit node and compares the content it gets back with what it
-"should" get back. The goal is to notice misconfigured, broken, and even
-malicious exit relays. Alas, the code is
-currently written in rather rickety perl and relies on MD5sums of
-entire documents in order to determine if exit nodes are modifying
-content. The problem with this is threefold: 1) Perl sucks at life.
-2) The scanner can't verify pages that are dynamic, and attackers can
-focus malicious content injection on only those dynamic pages. 3)
-Pages change after a while (or based on GeoIP) and begin generating
-false positives.
-<br />
-Ideally, soat.pl would be reimplemented in a sane language with a
-robust html parser library (since the rest of Torflow is in Python
-that would be nice, but it is not required), and calculate signatures only for
-tags and content likely to be targeted by a malicious attacker (script
-tags, object links, images, css). It should also be robust in the face of
-changes to content outside of Tor, and ultimately even GeoIP localized
-content.
