: "1396K" indicates the list contains approximately 1.39 million pairs of credentials [2].
: The list is likely compiled from breaches of crypto-adjacent websites (forums, news sites, or smaller exchanges), under the assumption that users often reuse passwords across different financial platforms [1, 4]. How the Attack Works
: This label suggests the data has been "cleaned" or "refined" to remove duplicates or junk data, making it more effective for automated attacks [3].
: Never reuse passwords between services. Use a dedicated password manager to generate unique, complex passwords for every site [6].
: An attacker loads the 1.39M credentials into a "checker" or "sentry" bot [2].
The string refers to a massive collection of compromised credentials (usernames/emails and passwords) specifically curated to target cryptocurrency users, particularly those on platforms like Binance and IC Markets . What is this "Combolist"?
: Enable hardware-based (YubiKey) or app-based (Google Authenticator) MFA. Avoid SMS-based MFA, as it is vulnerable to SIM swapping [7].
: Use services like Have I Been Pwned to see if your email is part of this or other known breaches [1].
