3. INTRODUCTION What is trojan Basically trojan is a Program used to gain access the victims computers. Fully Controls the victims Computer Used to hack the remote Computer

4. Types of Trojans Remote Access Trojans Password Sending Trojans KeyLoggers Destructive Trojans Denial of Service (DoS) Attack Trojans Proxy/Wingate Trojans FTP Trojans

5. Working of the Trojan Trojan has 2 Components * A Client Component * A Server Component Server part get installed in victims Computer Client Program operated by attacker

6. Hacking the Remote Computer Attacker tries to install the server part in victims Computer Attacker gets the ip address and port number of the victims computer Using the Client part attacker attacker monitors the remote computer (can access the files, monitor key logs, can crash entire system)
