The real issue here is somewhere there is a Game Over Zeus
infected client that is web browsing through the Tor network.
We have no way of alerting that host to their compromised status.
At least and unless entry nodes have a means for detecting infected
clients. Which I believe is not the case.
Anti virus software is poor at detecting this type of trojan.
It is a difficult problem we would do well to give thought to.
