The rns.tn Leak Exposed 642 Email and Password Combinations

HEROIC analysts found a combolist tied to the domain rns.tn, uploaded to a Telegram channel on June 10, 2026. The file contains 642 records, each pairing an email address with a plaintext password and the URL confirming where that login applies.

Why This Is Dangerous

Because every password in this file is stored in plaintext, anyone who downloads it can start using the credentials right away, no cracking tools or extra effort required. The URLs included with each record point attackers directly to the accounts tied to rns.tn, saving them the guesswork of figuring out where to try each login.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated URLs

Why This Matters

A leak focused on a single domain is often more dangerous than it looks, because every account in the file is confirmed to belong to that same service. Attackers can use these 642 email and password pairs for credential stuffing against other sites where the same login was reused, opening the door to account takeover, financial fraud, and identity theft for anyone affected.

How Combolists Work

A combolist gathers email or username and password pairs, often sourced from stealer logs or earlier breaches, into a single file ready for immediate use. When a combolist is built around one domain, like rns.tn, it usually means the credentials were harvested or filtered specifically from users of that site, making the list more targeted and reliable for an attacker than a random mixed dump.

Check If You Are Affected

Even at 642 records, if your email is one of them, the exposure is just as real as in a much larger leak. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including combolists like this rns.tn leak, so you can find out immediately and change any reused passwords before they are exploited.
