Also called a hyperlink trick, an obfuscated URL is a type of attack where the real URL that a user is directed to is obfuscated – or concealed – to encourage the user to click-through to the spoof Web site. For example, the attacker may use a cleverly misspelled domain name (e.g. PayPals.com instead of PayPal.com), or hide the actual URL in friendly text, such as “click here to verify your account now”. Obfuscated URLs are commonly used in phishing attacks and other spam e-mails.
Generally, any item that can be individually selected and manipulated. This can include shapes and pictures that appear on a display screen as well as less tangible software entities. In object-oriented programming, for example, an object is a self-contained entity that consists of both data and procedures to manipulate the data.
- object code
)The code produced by a compiler. Programmers write programs in a form called source code. The source code consists of instructions in a particular language, like C or FORTRAN. Computers, however, can only execute instructions written in a low-level language called machine language. To get from source code to machine language, the programs must be […]
- object oriented
A popular buzzword that can mean different things depending on how it is being used. Object-oriented programming (OOP) refers to a special type of programming that combines data structures with functions to create re-usable objects (see under object-oriented programming). Object-oriented graphics is the same as vector graphics. Otherwise, the term object-oriented is generally used to […]
- object-oriented graphics
The representation of graphical objects, such as lines, arcs, circles, and rectangles, with mathematical formulas. This method of describing objects enables the system to manipulate the objects more freely. In an object-oriented system, for example, you can overlap objects but still access them individually, which is difficult in a bit-mapped system. Also, object-oriented images profit […]
- Object-Oriented Programming
A type of programming in which programmers define not only the data type of a data structure, but also the types of operations (functions) that can be applied to the data structure. In this way, the data structure becomes an object that includes both data and functions. In addition, programmers can create relationships between one […]
