In the context of network security, a spoofing attack is a situation in which one person or program successfully masquerades as another by falsifying data and thereby gaining an illegitimate advantage. Network security consists of the provisions made in an underlying computer network infrastructure, policies adopted by the network administrator to protect the network and the network-accessible resources from unauthorized access and the effectiveness (or lack) of these measures combined together. ...
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 cryptanalytic effort. The German Lorenz cipher machine, used in World War II for encryption of very high-level general staff messages Cryptography (or cryptology; derived from Greek κÏυπτός kryptós hidden, and the verb γÏάφω gráfo write or λεγειν legein to speak) is the study of message secrecy. ...

Cryptanalysis (from the Greek kryptós, hidden, and analýein, to loosen or to untie) is the study of methods for obtaining the meaning of encrypted information, without access to the secret information which is normally required to do so. ...
The attacker must monitor the packets sent from Alice to Bob and then guess the sequence number of the packets. Then the attacker knocks out Alice with a SYN attack and injects his own packets, claiming to have the address of Alice. Alice's firewall can defend against some spoof attacks when it has been configured with knowledge of all the IP addresses connected to each of its interfaces. It can then detect a spoofed packet if it arrives at an interface that is not known to be connected to the IP address. A SYN flood is a form of denial-of-service attack in which an attacker sends a succession of SYN requests to a targets system. ...

Many carelessly designed protocols are subject to spoof attacks, including many of those used on the Internet. See Internet protocol spoofing In computer networking, the term Internet Protocol spoofing (IP spoofing) is the creation of IP packets with a forged (spoofed) source IP address. ...
URL spoofing and phishing Another kind of spoofing is "webpage spoofing," also known as phishing. In this attack, a legitimate web page such as a bank's site is reproduced in "look and feel" on another server under control of the attacker. The intent is to fool the users into thinking that they are connected to a trusted site, for instance to harvest user names and passwords. An example of a phishing email, disguised as an official email from a (fictional) bank. ...
This attack is often performed with the aid of URL spoofing, which exploits web browser bugs in order to display incorrect URLs in the browsers location bar; or with DNS cache poisoning in order to direct the user away from the legitimate site and to the fake one. Once the user puts in their password, the attack-code reports a password error, then redirects the user back to the legitimate site. A Spoofed URL describes one website that poses as another. ...

Referer spoofing Some websites, especially pornographic paysites, allow access to their materials only from certain approved (login-) pages. This is enforced by checking the Referer header of the HTTP request. This referer header however can be changed (known as "Referer spoofing" or "Ref-tar spoofing"), allowing users to gain unauthorized access to the materials. A paysite, in pornography slang, is a pornographic website that charges money for admission, unlike free sites such as TGPs. ...
Referer is a common misspelling of the word referrer; so common, in fact, that it made it into the official specification of HTTP - the communication protocol of the world wide web. ...

In computer security, Referer spoofing or ref tar spoofing is the sending of incorrect Referer information along with an HTTP request, with the aim of gaining unauthorized access to a web site. ...
Poisoning of file-sharing networks "Spoofing" can also refer to copyright holders placing distorted or unlistenable versions of works on file-sharing networks, to discourage downloading from these sources. Not to be confused with copywriting. ...

Caller ID spoofing In public telephone networks, it has for a long while been possible to find out who is calling you by looking at the Caller ID information that is transmitted with the call. There are technologies that transmit this information on landlines, on cellphones and also with VoIP. Unfortunately, there are now technologies (especially associated with VoIP) that allow callers to lie about their identity, and present false names and numbers, which could of course be used as a tool to defraud or harass. Because there are services and gateways that interconnect VoIP with other public phone networks, these false Caller IDs can be transmitted to any phone on the planet. Due to the distributed geographic nature of the Internet, VoIP calls can be generated in a different country to the receiver, which means that it is very difficult to have a legal framework to control those who would use fake Caller IDs as part of a scam.

E-mail address spoofing -
Main article: E-mail spoofing The sender information shown in e-mails (the "From" field) can be spoofed easily, though nowadays many domains have the Sender Policy Framework implemented, which helps prevent the e-mail spoofing. This technique is commonly used by Spammers to hide the origin of their e-mails and leads to problems such as misdirected bounces (i.e. e-mail spam backscatter). The spammers use a reliable "From" e-mail address so that they gain trust and authority, yet if the possible victim replies, the reply will be delivered to the spammer's e-mail address and not to the e-mail available on "From": reliable e-mail used in spoofing “Spoofing†is a term used to describe fraudulent email activity in which the IP address of the original sender is changed to appear as if it originated from a different IP address. ...
