How the safebox.ru Leak Put 709 Login Credentials Up for Grabs

HEROIC analysts found a small file uploaded to Telegram in June 2026 titled "safebox.ru - 709 emails." The upload contains 709 records, each pairing an email address with a plaintext password and the URL tied to the safebox.ru domain.

Why the safebox.ru Leak Is Dangerous

Every credential in this file is stored in plaintext, so there's nothing standing between whoever downloads the file and a working login. Even though 709 records is a small number compared to major breaches, each one represents a real account that someone could log into right now.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs tied to the safebox.ru domain

Why This Matters

Small, domain-specific leaks like this one are often used for targeted credential stuffing rather than broad, random attacks. Because every record in the file is connected to the same domain, an attacker can focus their efforts on accounts they already know share something in common, increasing the odds that a reused password will work.

How This Combolist Ended Up on Telegram

Domain-specific combolists like this one are usually pulled together by scraping login pages, harvesting credentials from smaller breaches, or purchasing a batch from another criminal, then filtering the results down to a single site or service before uploading. Packaging the file with the domain name in the title makes it easier for buyers to find exactly the kind of access they're looking for.

Check If You Are Affected

If you have ever had an account tied to safebox.ru, it's worth checking now. HEROIC's free breach scanner checks your email against more than 400 billion leaked records, including small uploads like this one, so you can catch a compromised password before it causes bigger problems.
