WHAT IS TROJAN ?
HOW DO TROJAN WORKS ?
• Nothing But a Server Client Program
• Uses TCP/IP protocol as well as UDP protocol
• It is only be send to the target system by user interaction only.
TASKS OF THE TROJAN
• erasing or overwriting data on a computer
• corrupting files in a subtle way
• spreading other malware, such as viruses. In this case the Trojan horse is called a 'dropper'.
• To launch DDoS attacks or send Spam.
• logging keystrokes to steal information such as passwords and credit card numbers (known as a key logger)
• phish for bank or other account details, which can be used for criminal activities.

HOW TO ATTACH THE TROJAN?
• Without Changing the File size• Generally Attached with game or email
WHERE THEY LIVE….
• Autostart FolderThe Autostart folder is located in C:\Windows\Start Menu\Programs\startup and as its name suggests, automatically starts everything placed there.
• Win.iniWindows system file using load=Trojan.exe and run=Trojan.exe to execute the Trojan
• Trojan horse attack, used a quantum cryptographic key algorithm with EPR pairs.
• With Quantum cryptography we can create a communication chancel where it is impossible to eavesdrop without disturbing the transmission.
• Remote Access Trojans• Password Sending Trojans• Denial Of Service (DoS) Attack Trojans• Keyloggers
HOW CAN YOU BE INFECTED……
• Via Email (Attachments)• Physical Access• Visiting Untrusted websites • Peer to peer download system• Installing the untrusted software's.
WHAT IS ATTACKER LOOKING FOR ?• Credit Card Information (often used for domain registration, shopping with your credit
