Beware of these common e-mail tactics used to commit fraud.​


This is an online scam that seeks to steal credit card numbers, account information, Social Security numbers, passwords, and other sensitive information by using fake e-mails, fraudulent Internet addresses, imposter websites, and "pop-ups" to impersonate Comerica Bank and trick customers into disclosing their personal data.


Similar in nature to e-mail phishing, pharming seeks to obtain personal or private (usually financial related) information through domain spoofing. Pharming "poisons" a DNS server by infusing false information into the DNS server, resulting in a user's request being redirected elsewhere. Your browser however will show you are at the correct website, which makes pharming a bit more serious and more difficult to detect. As phishing attempts to scam people one at a time with an e-mail, pharming allows the scammers to target large groups of people at one time through domain spoofing.


Spam is electronic junk mail or unsolicited e-mail.


Spoofing is a broad term for behaviors that involve a person or entity masquerading as a trusted source, such as when a caller deliberately falsifies the information transmitted to your caller ID display to appear as though they are someone else, such as your local police department or bank. Email addresses, IP addresses and even websites can all be spoofed so they appear to be legitimate when in fact they are not.

To help keep your personal information out of the wrong hands:

  • Don't click the link. If you are concerned about the authenticity of an e-mail, contact your bank directly by phone beforehand. You may also go directly to your institution's site by typing the URL in the browser. If you go directly to the site, check for indicators that the pages are secure, such as a padlock symbol at the bottom of the page and a URL that begins with "https" instead of "http".
  • Change your passwords periodically, using strong passwords that could not be easily guessed. For example, do not use names (e.g., your mother's maiden name), familiar dates, (e.g., your birthday) or your Social Security number (SSN).
  • Always log off from your Comerica Web Banking® session. Shut off your computer or disconnect from the Internet when not in use.
  • Check merchant privacy policies and only shop at those that publish privacy policies with which you agree.​
