Recently some card issuers and financial institutions across the industry have experienced an increase in attempts by unknown fraudsters to break the card verification value / card verification code (CVV / CVC) on compromised cards, and thereby to commit card fraud, including ATM fraud. This attempt to commit fraud is commonly known as a “brute force attack”. To execute these crimes, email is often used to transport phishing scams and malicious software (malware) to obtain personal information including personal identification numbers (PINs) and to take over legitimate merchant accounts to test the compromised cards.
You can help to reduce the likelihood of the success of these attempts to commit fraud by being alert for email that :
(1) contains unfamiliar or suspicious links or attachments,
(2) is unsolicited and/or from an unknown sender,
(3) is sent multiple times from different senders, or
(4) contains poor grammar or incorrectly spelled words.
If you receive email that contains any of these elements or any combination of these elements, you should delete it immediately. Do not open it, click on the links or open any attachment. You should not attempt to reply to the email or forward it to anyone.
