2. Hack A Hack is usually a technique used to subvert, misuse or cleverly change a program, gadget or mechanism in such a way as to change, or add to, its functionality. Hack has several meanings in the technology and computer science fields: a clever or quick fix to a computer program problem; a clumsy or inelegant solution to a problem; or a modification of a program or device to give the user access to features that were otherwise unavailable to them. From Wikipedia

5. DDoS A denial-of-service attack (DoS attack) or distributed denial-of-service attack (DDoS attack) is an attempt to make a computer resource unavailable to its intended users. Although the means to carry out, motives for, and targets of a DoS attack may vary, it generally consists of the intensive, malicious efforts of a person or persons to prevent an Internet site or service from functioning efficiently or at all, temporarily or indefinitely.

7. Sniffing Promiscuous Sniffing: An Ethernet sniffer or wireless sniffer is computer software or computer hardware that can intercept and log traffic passing over a digital network or part of a network. As data streams flow across the network, the sniffer captures each packet and eventually decodes and analyzes its content according to the appropriate RFC or other specifications.

Spoofing Monkey in the Middle: is an attack in which an attacker is able to read, insert and modify at will, messages between two parties without either party knowing that the link between them has been compromised. The attacker must be able to observe and intercept messages going between the two victims.
