Hacking For Beginners – Manthan Desai 2010 1. Server component of the Trojan opens a port in the Victim’s computer and invites the Attacker to connect and administrate the computer. 2. Client component of the Trojan tries to connect the Victim’s computer and administrate the computer without the permission of the User. Wrapper A Wrapper is a program used to combine two or more executables into a single packaged program. The wrapper attaches a harmless executable, like a game, to a Trojan’s payload, the executable code that does the real damage, so that it appears to be a harmless file. Hackers use Wrappers to bind the Server part of the Software behind any image or any other file. Wrappers are also known as Binders. Generally, games or other animated installations are used as wrappers because they entertain the user while the Trojan in being installed. This way, the user doesn’t notice the slower processing that occurs while the Trojan is being installed on the system—the user only sees the legitimate application being installed. w w w . h a c k i n g t e c h . c o . t v Page 46
Hacking For Beginners – Manthan Desai 2010 Mode of Transmission for Trojans Reverse Connection in Trojans Reverse-connecting Trojans let an attacker access a machine on the internal network from the outside. The Hacker can install a simple Trojan program on a system on the internal network. On a regular basis (usually every 60 seconds), the internal server tries to access the external master system to pick up commands. If the attacker has typed something into the master system, this command is retrieved and executed on the internal system. Reverse WWW shell uses standard HTTP. It’s dangerous because it’s difficult to detect - it looks like a client is browsing the Web from the internal network Now the final part …. Detection and Removal of Trojans The unusual behavior of system is usually an indication of a Trojan attack. Actions/symptoms such as, • Programs starting and running without the User’s initiation. • CD-ROM drawers Opening or Closing. • Wallpaper, background, or screen saver settings changing by themselves. • Screen display flipping upside down. • Browser program opening strange or unexpected websites All above are indications of a Trojan attack. Any action that is suspicious or not initiated by the user can be an indication of a Trojan attack. One thing which you can do is to check the applications which are making network connections with other computers. One of those applications will be a process started by the Server Trojan. w w w . h a c k i n g t e c h . c o . t v Page 47
