An exploit (from the verb to exploit, in the meaning of using something to one’s own advantage) is a piece of software, a chunk of data, or sequence of commands that takes advantage of a bug, glitch or vulnerability in order to cause unintended or unanticipated behaviour to occur on computer software, hardware, or something electronic (usually computerised). Such behavior frequently includes such things as gaining control of a computer system or allowing privilege escalation or a denial-of-service attack...

Assembly language is essentially the native language of your computer. Technically the processor of your machine understands machine code (consisting of ones and zeroes). But in order to write such a machine code program, you first write it in assembly language and then use an assembler to convert it to machine code.

In cryptanalysis and computer security, password cracking is the process of recovering passwords from data that has been stored in or transmitted by a computer system. A common approach is to repeatedly try guesses for the password. Another common approach is to say that you have "forgotten" the password and then change it.

In computer science, session hijacking is the exploitation of a valid computer session—sometimes also called a session key—to gain unauthorized access to information or services in a computer system. In particular, it is used to refer to the theft of a magic cookie used to authenticate a user to a remote server. It has particular relevance to web developers, as the HTTP cookies used to maintain a session on many web sites can be easily stolen by an attacker using an intermediary computer or with access to the saved cookies on the victim's computer (see HTTP cookie theft)....

A backdoor in a computer system (or cryptosystem or algorithm) is a method of bypassing normal authentication, securing illegal remote access to a computer, obtaining access to plaintext, and so on, while attempting to remain undetected. The backdoor may take the form of an installed program (e.g., Back Orifice) or may subvert the system through a rootkit.
