Fusker is a type of website or utility that extracts images in bulk from a website (typically from free hosted galleries) by systematically loading and downloading images following a pattern in the website's URL scheme. Fusking or fuskering is often used to extract private and nude photos without consent of the owner.[1]
Fusker software allows users to identify a sequence of images with a single pattern, for example: http://www.example.com/images/pic[1-16].jpg. This example would identify images pic1.jpg through pic16.jpg. When this pattern is given to a fusker website, the website would produce a page that displays all sixteen images in that range. Patterns can also contain lists of words, such as http://www.example.com/images/{small,medium,big}.jpg, which will produce three URLs, each with one word from the bracketed list. The web page is then presented to the person who entered the fusker, and can also be saved on the fusker web server so that other people may view it.
