Wikipedia: “Another use of URL shortening is to disguise the underlying address. Although this may be desired for legitimate business or personal reasons, it is open to abuse.”
The goal of Phishing emails is to trick you into revealing your information. The email contains a link that appears real, but it isn’t. The web-site looks like the real site, but it isn’t. When you enter your user name and password, you have opened your account to the thief.
Shortened URLs have made this easier. We have started to get use to bit.ly/iYsdGa or yhoo.it/yyGvrT. We click without thinking. Oops your bank account is now empty.
If the click sends you to a site that requests login information, or other personal information, do not enter it. Close the page and reopen the page by typing the url or using a trusted link in favorites. Then enter your information.
Be wise. Be safe.
