Analysis

The researcher acquired the shared file and carefully examined the data. The file comprises an estimated 1.9 million cards, including debit, credit, and charge cards. It is structured as a CSV text document, with each column separated by the ‘|’ symbol. Each row includes the complete card number, expiration date, and CVV. Notably, this dump lacks additional bank information and card owner details, which were previously uploaded earlier in the year (BidenCash Dump 2.1M Compromised Debit/Credit Cards). The sample below illustrates the format of the dump file.

There are a total of 1,912,935 card numbers listed in the file. None of these cards have expired, and 75% of them are projected to expire in the next few years, as shown below.

There are almost 60% of the card are Visa and almost 40% are Mastercard as shown below.

Summary

The release of this information has a significant impact on the affected users, not just the financial institutions. In the short term, it is crucial to protect the impacted users by disabling their cards to reduce the risk of fraudulent activity.
