Through ongoing phishing attacks, you have got another customer's username and password.
You then attempted to retrieve 16-digit credit card number and 3-digit CCV number as usual.
But you have found you cannot use the previous gap to retrieve data since a security researcher reported the gap to the vendor who has since fixed it, saying it was due to a technical error.
For the challenge flag, provide your discovered 16-digit credit card number and 3-digit CCV number separated by a comma. (eg. 1234-1234-1234-1234,123).
