The Sample Mail RU Combolist Could Let Someone Log Into Your Email

The Sample Mail RU Combolist Exposes 34 Accounts

HEROIC analysts identified a combolist labeled Sample Mail RU, uploaded by a Telegram user on 30 Jul 2026. The file contains 34 records, each combining an email address with a plaintext password and the URL of the login page it unlocks.

Why This Is Dangerous

With the password already in plaintext and matched to the correct login URL, anyone holding this file can try signing into the affected inbox or account directly. There is no password hash to crack and no guesswork about where the credential belongs.

What Was Exposed in the Sample Mail RU Combolist

• Email addresses
• Plaintext passwords
• URLs of the associated login pages

Why This Matters

A leak of 34 accounts is easy to overlook, but for the people involved, the risk is identical to any larger breach. If the password in this file matches one used on other accounts, an attacker can log into email first, then use that access to reset passwords on banking or shopping sites through credential stuffing, opening the door to identity theft and financial fraud.

How This Combolist Was Likely Assembled

Combolists like this one are typically pulled together from older breaches and leaks, with the email and password pairs checked against live sites to confirm which ones still work. The surviving, working pairs are then packaged into a smaller, cleaner file, in this case one tied to Mail.ru style addresses, and shared on Telegram.

Check If You Are Affected

Don't assume a small leak means you're safe. Run your email through HEROIC's free breach scanner, which checks against more than 400 billion leaked records, to see right away if your credentials were part of this leak.
