phising mail

In the field of computer security, phishing is the criminally fraudulent process of attempting to acquire sensitive information such as usernames, passwords and credit card details by masquerading as a trustworthy entity in an electronic communication. Communications purporting to be from popular social web sites, auction sites, online payment processors or IT administrators are commonly used to lure the unsuspecting public. Phishing is typically carried out by e-mail or instant messaging and it often directs users to enter details at a fake website whose look and feel are almost identical to the legitimate one. Even when using server authentication, it may require tremendous skill to detect that the website is fake. Phishing is an example of social engineering techniques used to fool users, and exploits the poor usability of current web security technologies.Attempts to deal with the growing number of reported phishing incidents include legislation, user training, public awareness, and technical security measures.

A phishing technique was described in detail in 1987, and the first recorded use of the term "phishing" was made in 1996. The term is a variant of fishing,[4] probably influenced by phreaking, and alludes to baits used to "catch" financial information and passwords.

How to tell if an e-mail message is fraudulent

Here are a few phrases to look for if you think an e-mail message is a phishing scam.

"Verify your account."
Businesses should not ask you to send passwords, login names, Social Security numbers, or other personal information through e-mail.

If you receive an e-mail from Microsoft asking you to update your credit card information, do not respond: this phishing scam. To learn more, read Fraudulent e-mail that requests credit card information sent to Microsoft customers.

"If you don't respond within 48 hours, your account will be closed."
These messages convey a sense of urgency so that you'll respond immediately without thinking. Phishing e-mail might even claim that your response is required because your account might have been compromised.

"Dear Valued Customer."
Phishing e-mail messages are usually sent out in bulk and often do not contain your first or last name.

"Click the link below to gain access to your account."
HTML-formatted messages can contain links or forms that you can fill out just as you'd fill out a form on a Web site.
The links that you are urged to click may contain all or part of a real company's name and are usually "masked," meaning that the link you see does not take you to that address but somewhere different, usually a phony Web site.
Notice in the following example that resting the mouse pointer on the link reveals the real Web address, as shown in the box with the yellow background. The string of cryptic numbers looks nothing like the company's Web address, which is a suspicious sign.
