You may have heard the term phishing. Phishing refers to the practice of tricking someone into revealing private information. Fishing and phishing are similar concepts -- there's bait involved with both. With a phishing scheme, that bait might be as simple as a text message or e-mail. It may be as complex as a fake Web site designed to mimic your bank's official site, which is called spoofing.
You should never follow a banking link sent to you in a text message or e-mail. These links could potentially lead you to a spoofed Web site. If you enter your information into such a site, you've just handed that data over to thieves. It's always a good idea to navigate to a Web site directly. Enter your bank's Web address into your phone and bookmark it. This will help you avoid bogus Web sites.
On a related note, you should never send your account information or password via text message or e-mail. It's a common phishing scheme to send out bogus requests for such information. Don't fall for it!
