The trojan bakdoors, i think is not efective because the firewall

block incoming ports and is very dificult to access the server (trojan)

for outside connections, only receiving information is capable, port

what the firewall allow to outside, and the information what can the

client receive is very poor, everything depend of FireWall rules.

if the firewall is open to send any connections the trojan work.
