The act of sending an email to a user falsely claiming to to be an established legitimate enterprise in an attempt to scam the user into surrendering private information that may be used for identity theft. This can include requesting the user to email back their confidential information or providing a link to a fraudulent website which requests the information (web-spoofing).

Similar to phishing except that the "bait" is delivered via SMS rather than an email.
A scam, usually used in conjunction with phishing, where a criminal attempts to obtain a users personal and financial information via a fake website that looks legitimate. The fake website requests you to enter confidential information. The fake site may look legitimate but it will not have the correct URL.
Pharming is similar to web-spoofing in that it directs the user to a fake website that looks legitimate. However, rather than using phishing to direct the user to the site, pharming requires a domain name server (DNS) to be hacked. A compromised DNS is often reffered to as "poisoned". When the user attempts to go to the legitimate site the DNS will instead direct them to the false site. The user's browser will still show the URL of the legitimate site.[2]
Electronic eavesdropping is the act of intercepting electronic packets of information usually for criminal purposes. It is often referred to as "Packet-Sniffing". The criminal tries to reconstruct the data from the packets which he has obtained from using a rogue computer on the network (or the internet).
A denial-of-service attack (DoS attack) or distributed denial-of-service attack (DDoS attack) is an attempt to make a computer or network 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 concerted efforts of a person, or multiple people to prevent an Internet site or service from functioning efficiently or at all, temporarily or indefinitely.
Perpetrators of DoS attacks typically target sites or services hosted on high-profile web servers such as banks, credit card payment gateways, and even root nameservers.
One common method of attack involves saturating the target machine with external communications requests, such that it cannot respond to legitimate traffic, or responds so slowly as to be rendered effectively unavailable. Such attacks usually lead to a server overload. In general terms, DoS attacks are implemented by either forcing the targeted computer(s) to reset, or consuming its resources so that it can no longer provide its intended service or obstructing the communication media between the intended users and the victim so that they can no longer communicate adequately.
E.g. An attacker send millions of emails to somebody so that they cannot use their email or internet.
Usually an e-mail message that warns people about a virus that does not exist. Usually is over-the-top, warning people that the virus can do impossible things (like burning out your hard drive or frying your RAM). Often contains capitals, exclamation mark, bad spelling and grammar, says it comes from several well-known companies (few of which are likely to be antivirus companies) and encourages you to forward the message to all people you know before the world ends! It has the detrimental effect of generating large volumes of unnecessary email traffic from panicked network users.
