What is “Phishing”?

Phishing is the method of tricking people into providing their social security numbers, credit card numbers, mother’s maiden name and other personal information. It is becoming apparent that the volume of phishing attempts through email is on the rise. “Phishers” often pretend to be someone else, such as a financial institution, retailer, government agency or other organization. This may include altering the “from” address of a message to make it appear to originate from a legitimate source.

There are a variety of methods that hackers may use in order to gain one’s confidence. For example, a member may receive an email claiming that there is a problem with their account or that their account will be closed unless they provide specific information. The most recent fraudulent attempts include emails claiming that a recent bill payment or ACH transaction was rejected. The sender may ask to verify an address, account number or password. A phishing email could also include an attachment containing a virus to steal sensitive information. Additionally, an emailed website link could be embedded that will lead to a fake site designed to look like a legitimate site, in an attempt to obtain sensitive information.

Always know that DCECU will never ask you to provide your account information in this manner. Furthermore, DCECU emails will never:
  • Include unsolicited attachments
  • Request account-specific information (account numbers, usernames, passwords, card numbers, etc.)
  • Include links directing you to an Online Banking login page
If an email includes any of the above, then it is most likely a phishing attempt. If you have any concerns that an email may be a phishing attempt, Online Banking (via can always be used to verify account balances, transaction history, and other related information. If you believe that you may have fallen victim to a phishing attack, or still have any questions, please contact the Credit Union at (989) 835-7794 or (800) 835-7794.

Examples of Phishing

  1. One common example of a phishing scam uses false alerts to trick the user with a fake login page:
    From: billcenter <>
    Sent: Tuesday, October 7, 2011 11:43 PM
    Subject: Important Notice from DCECU Billing Center

    Dear Dow Chemical Employee's Bank customer,


    Thank you,
    Chemicale Employee's Bank

  2. A phishing example that targets common banking services:
    From: NACHA <>
    Sent: Tuesday, September 6, 2011 1:43 AM
    Subject: ACH Transfer Review

    Dear Client,

    ACH transfer (ID:620734) is going to be reviewed because of the
    incorcrectly input data
    when sending the payment.

    Please,i fill ign the application form attached attentively and send it to
    After that your transfer will be processed.

    If you have any qukestions or comments, contact us at
    Thank you for using NACHA
    Cathy McNickle

These emails should raise many red flags that indicate a phishing attempt:

  • (1&2) Multiple, similar email addresses: Why would a specific alert be sent to more than one person, let alone people with the similar email addresses?
  • (1&2) "Dear Client/Customer": We will always address you by name or as "member."
  • (1&2) Many grammar and spelling mistakes: English is rarely the phishers' primary language.
  • (1) Target URL: Consider that dcecu is just part of the site's real domain name, which would be
  • (1) Is this email address even on file with DCECU? While phishers may spoof a from address in order to make the email appear legitimate, they often don't even bother.
  • (2) Zip attachment: Often used to (poorly) hide viruses. Only open attachments from trusted sources and always scan any attachments with anti-virus software before opening.

Remember: Not all phishing emails are created equal. Some phishing attempts may raise very few red flags. For example, we are Dow Chemical Employees' Credit Union, not Dow Chemical Employee's Credit Union. If you are ever concerned about the legitimacy of a DCECU communication, please contact us at (989) 835-7794 or (800) 835-7794.

What is “Vishing”?

Vishing Scams Use Phones Instead of Fake Websites
In a new twist, identity thieves are sending spam that warns victims that their credit union/bank account or PayPal accounts were supposedly compromised. However, unlike typical phishing emails, there is no website address in these phishing messages. Instead, the victim is urged to call a phone number to verify account details.

The automated voice message says: “Welcome to account verification. Please type your 16-digit card number.” The goal is to get the victim to enter their credit card number. In these reported scams, no mention of the credit union, bank or PayPal is made.

Security experts tracking this scam and other instances of “vishing”, short for “voice phishing”, maintain that these frauds are particularly despicable because they imitate the legitimate ways people interact with financial institutions. In fact, some vishing attacks do not begin with an email. Some come as calls out of the blue, in which the caller already knows the recipient's credit card number. This increases the perception of legitimacy and the caller only asks for the valuable three-digit security code on the back of the card. Vishing appears to be prospering with the help of Voice over Internet Protocol, or VoIP, the technology that enables cheap and anonymous Internet calling, as well as the ease with which caller ID boxes can be tricked into displaying erroneous information.

How to prevent loss:
  • Never call a number you receive from a spam email, and certainly do not enter in any private information if you make a mistake and do call. If you want to call your financial institution, use the normal phone number you regularly use, not the phone number you get in an email.
  • Remember that your credit union will NEVER solicit personal/private information via email.
  • Never click on the link provided in an email you believe is fraudulent.
  • Do not open suspicious email attachments.
  • Do not be intimidated by an email or caller who suggests dire consequences if you do not immediately provide or verify information.
  • Secure your computer against viruses, spyware, and malware and update these regularly.

If you are a victim of a phishing or vishing attempt, feel free to contact us at (989) 835-7794 or (800) 835-7794. You may also wish to take appropriate steps to protect yourself by canceling your compromised credit/debit cards, reporting the incident to the credit bureaus, or by ordering a copy of your credit report from any or all of the following:
