HEROIC Researchers Trace 1,831-Record Leak to bsnow.net Combolist

HEROIC analysts traced a combolist uploaded by a Telegram user on 10 June 2026 back to bsnow.net, identifying 1,831 exposed records in the file. Each record pairs an email address with a plaintext password and the URL of the login page it belongs to, giving anyone who obtains the list a working set of account credentials.

Why This Is Dangerous

Researchers noted that the passwords in this list are stored in plaintext rather than hashed or encrypted, meaning an attacker can read them directly with no cracking involved. Paired with the matching login URLs, the file functions as a ready-made attack list rather than a raw data dump that would need further work to exploit.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated login URLs

Why This Matters

Even at 1,831 records, this list gives an attacker enough material for a focused credential stuffing campaign. Automated tools can test each stolen email and password pair against banking sites, email providers, and other platforms in minutes. Anyone tied to bsnow.net who reused one of these passwords elsewhere risks account takeover, financial fraud, or identity theft.

How Combolists Work

A combolist is a compiled text file of email and password pairs, typically pulled from earlier breaches, phishing campaigns, or stealer malware and merged into one list. Criminals build combolists specifically to power credential stuffing attacks, automating thousands of login attempts against websites to see which passwords still work. Researchers regularly trace lists like this bsnow.net combolist back to Telegram channels, where they are shared and traded before spreading further across dark web marketplaces.

Check If You Are Affected

Reusing a password anywhere is the main reason a leak like this can compromise more than one account. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, so you can quickly find out whether your credentials appear in this combolist or any other and secure your accounts before someone else does.
