Snarfing
Snarf is a term used by computer programmers meaning to grab a large document, file or any data, and use it without the author's (owner) permission. In the UNIX community the term means the acquisition of a file or set of files across a network. It also refers to using command line tools to transfer files through the HTTP, gopher, finger and FTP protocols without user interaction.
== Example ==
An example of a "snarf" is the Evil twin attack, using a simple shell script running software like AirSnarf to create a wireless hotspot complete with a captive portal. Wireless clients that associate to a snarf access point will receive an IP, DNS, and gateway and appear completely normal. Users will have all of their DNS queries resolve to your IP, regardless of their DNS settings, so any website they attempt to visit will bring up a snarf "splash page", requesting a username and password. The username and password entered by unsuspecting users will be mailed to root@localhost. The reason this works is 1) legitimate access points can be impersonated and/or drowned out by rogue access points and 2) users without a means to validate the authenticity of access points will nevertheless give up their hotspot credentials when asked for them.
