The ’10K CC Database’ Leak Sat Quiet for a Year. It Just Surfaced.

HEROIC analysts identified a file named 10K CC Database that was originally leaked around January 29, 2025, and has now surfaced more widely on Telegram. Despite the name, the confirmed contents are 9,585 records of email addresses, plaintext passwords, and login URLs, not credit card numbers. Why This Is Dangerous: Names like '10K CC Database' are often used to make a file sound more valuable or alarming than what it actually contains. In this case, no credit card data appears in the confirmed records, but the file still holds thousands of working email and password combinations in plain text, which is dangerous on its own. What Was Exposed: - Email addresses - Plaintext passwords - Associated login URLs Why This Matters: Even without credit card numbers, 9,585 plaintext email and password pairs are enough to cause real harm. If you reused any of these passwords elsewhere, attackers can use credential stuffing to log into your other accounts, including the financial and shopping accounts the file's name implies, leading to account takeover, financial fraud, or identity theft through indirect means. How Combolist Leaks Work: Files like this one are combolists, plain text lists of stolen or previously leaked email and password pairs, often relabeled with misleading names like 'CC Database' to attract buyers on Telegram, even when no actual payment card data is present. The real content is usually older breach data or malware output, repackaged and marketed under a more dramatic title. Check If You Are Affected: Whatever the file is called, the real risk is the 9,585 exposed logins inside it. HEROIC's free breach scanner checks your email against more than 400 billion leaked records, so you can confirm quickly whether your credentials appear here and take action before this data is used against you.
