Spoofing
A technique used to gain unauthorized access to computers, whereby the intruder sends messages to a computer with an IP address indicating that the message is coming from a trusted host. To engage in IP spoofing, a hacker must first use a variety of techniques to find an IP address of a trusted host and then modify the packet headers so that it appears that the packets are coming from that host.
A closely interconnected and often confused term with phishing and pharming is spoofing. A "spoofer", in Internet terms, is defined generally as the "cracker" who alters, or "forges", an e-mail address, pretending to originate a message from a different source address than that which he or she truly has. There are many ways an attacker may do this, and there are many types of attacks. The attacker may do this to gain access to a secured site that would accept the "hijacked" address as one of few permissible addresses, or more maliciously, the reason may be to hide the source of any type of attack. Email spoofing is often an attempt to trick the user into making a damaging statement or releasing sensitive information (such as passwords).
Spoofing Attacks Techniques
Spoofing attacks can be divided into different categories, some of which are
elaborated below:
Man-in-the-middle attack and internet protocol spoofing
An example from cryptography is the man-in-the-middle attack, in which an attacker
spoofs Alice into believing they're Bob, and spoofs Bob into believing they're Alice,
thus gaining access to all messages in both directions without the trouble of any.
