The ’30k’ Combolist Could Unlock Your Email and Banking Logins

HEROIC analysts reviewed a combolist simply named 30k, uploaded to Telegram on 02-Aug-2025. Despite the filename, the actual file contains 27,444 verified records of email addresses, plaintext passwords, and linked URLs, a bit smaller than its name suggests but still a significant number of exposed logins. Why This Is Dangerous: Every password in this file is stored in plaintext, which means there is no encryption standing between an attacker and your account. Anyone who downloads the file can immediately try each email and password combination against other websites. What Was Exposed: - Email addresses - Plaintext passwords - URLs tied to each credential Why This Matters: A leak like this rarely stops at one account. If your email and password appear here and you have reused that same password anywhere else, an attacker can chain that single leaked credential into access for your email, your online shopping accounts, and potentially your banking or payment logins, especially if you rely on the same password everywhere. How a Combolist Like This Works: These files are assembled by combining credentials pulled from multiple smaller breaches, phishing kits, and malware logs into one list, then shared on Telegram under a short, catchy name to attract downloads. The name often overstates or understates the real size of the file, which is why the actual record count matters more than the title.
