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

Types of Trojans

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

• Information gathering• Sniffing • Spoofing• Session hijacking• Denial of service

Host Threats and Countermeasures

• Viruses, Trojan horses, and worms• Foot printing• Profiling• Password cracking• Denial of service• Arbitrary code execution• Unauthorized access
