Fraud Updates

  • Fraudsters spoofing Charter Oak Federal Credit Union’s phone number and asking the Members for banking information

Spoofing is when a caller deliberately falsifies the information transmitted to your caller ID display to disguise their identity. Hence, you may see Charter Oak’s phone number, but it may not be us calling you. We may call you to verify information you’ve already submitted to us or other reasons. However, we will never call you asking for your personal confidential information (social security number, account number, debit or credit card number, date of birth, etc.) When in doubt, ask for their name. Then hang up and call us! Our Contact Center will be happy to assist you.

When you call us, we will ask you some security questions to identify you as the account holder. We are protecting your information. You generated the call. This is different than someone calling you and it is okay to answer our questions.

  • Beware of Fraudulent Text Messages to Members seeking information

Scammers send fraudulent text messages which impersonate a government agency, bank, or other apparent legitimate company to validate their claims. (Examples are not inclusive.) Also known as “smishing”, these messages typically ask consumers to provide usernames and passwords, credit and debit card numbers, PINs, or other sensitive information. This obtained information is used to commit fraud.

Don’t be fooled! Never click on a link from an unknown sender. Also be leery of links from known senders, if it is unusual from them or you’re not expecting the link. It is always a good idea to call and verify the legitimacy of the text and link! Better to be Safe than Sorry!
