371.com Combolist Leaked 28,771 Emails and Passwords in Plaintext.

371.com Combolist Exposes 28,771 Email and Password Pairs

In June 2026, HEROIC analysts identified a combolist tied to 371.com circulating on Telegram. The file contained 28,771 records pairing email addresses with plaintext passwords, along with the URLs each credential was tied to. A file of this size means tens of thousands of individual accounts are now available to anyone who downloads it.

Why This Is Dangerous

Because every password in this file is stored in plaintext, there is no encryption for an attacker to break. The 28,771 email and password pairs can be loaded directly into automated login tools and tested against websites within minutes of the file being downloaded. Anyone whose credentials appear here is exposed the moment someone with access decides to use the list.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated URLs (the sites tied to each account)

Why This Matters

Combolists like this one are the raw material for credential stuffing, where stolen email and password combinations are automatically tested across many unrelated sites. Because these passwords are unencrypted, the barrier to abuse is lower than usual. Anyone in this list who reused a password elsewhere faces a real risk of account takeover, identity theft, and financial fraud.

How This Combolist Was Likely Built

Combolists such as the 371.com file are typically compiled from older breaches, phishing pages, or malware infections, then merged and labeled with a domain name to make the source appear more specific. The label does not always mean the domain itself was hacked. It often just describes what the credentials are associated with or where the list was collected from.

Check If You Are Affected

With 28,771 records in this single file, checking your exposure only takes a moment. HEROIC's free breach scanner searches a database of more than 400 billion leaked records, including combolists like this one, so you can find out if your email and password were part of this leak and take action before it is used against you.
