Search Your Email: The 190K Mix Access Leak Hit 197,834 Accounts

In late March 2026, HEROIC analysts identified a large combolist titled '190K Mix Access UHQ' uploaded to a Telegram channel by an individual user. Despite the '190K' in its name, the actual file contains 197,834 records, each pairing an email address with a plaintext password and an associated login URL. Why This Is Dangerous: A file of this size gives an attacker nearly 200,000 working email and password combinations to test against banking sites, email providers, streaming services, and anything else people log into. Because every password here is stored in plaintext, there's no cracking step involved, the credentials are ready to use the moment someone downloads the file. What Was Exposed: email addresses; plaintext passwords; associated login URLs. Why This Matters: At this scale, automated credential stuffing tools can run through the entire list in a matter of hours, quietly testing each pair across dozens of popular sites. Anyone in this file who reused a password elsewhere is at real risk of having that other account taken over, and from there, of falling into identity theft or financial fraud if the account touches banking or payment information. How Combolists Work: A combolist compiles previously leaked email-and-password pairs, often from multiple older breaches and malware logs, into one large, easy-to-distribute file. Labels like 'Mix' and 'UHQ' (ultra high quality) signal to buyers that the list has been cleaned and combined from several sources to maximize the number of working logins. Check If You Are Affected: With nearly 200,000 accounts involved, the odds that your email is somewhere in a leak like this one are higher than you'd think. Search your email for free with HEROIC's breach scanner, which checks against more than 400 billion leaked records, and change any password that comes back exposed.
