Rambler.ru Domain HQ Base Leak: 14,627 Records Exposed Online

A 2023 Rambler.ru Combolist Resurfaces With 14,627 Records

HEROIC analysts identified a combolist labeled "15k Rambler.ru Domain HQ Base" being shared on Telegram, originally tied to a February 2023 leak. The file was marketed as containing roughly 15,000 entries, but HEROIC's verification confirmed 14,627 records, each pairing an email address with a plaintext password and a linked URL. The "HQ Base" label suggests the credentials were tied specifically to Rambler.ru's main domain accounts rather than a mix of unrelated sources.

Why This Is Dangerous

Every password in this file is stored in plaintext, meaning anyone who obtains the list can read the credentials immediately. Although the underlying data is over three years old, it is still being traded today, which matters because many people never change passwords on accounts they consider secondary, like an old email or portal login.

What Was Exposed

• Email Addresses
• Plaintext Password
• URLs

Why This Matters

With 14,627 verified email and password pairs tied to Rambler.ru accounts, attackers have a direct target list for credential stuffing, both against Rambler.ru itself and against any other service where the same password was reused. Anyone affected faces a real risk of account takeover, financial fraud, or identity theft, even years after the original data was compiled.

How a Domain-Targeted Combolist Like This Keeps Circulating

Combolists organized around a specific domain, like this Rambler.ru base, are built by filtering stolen credentials down to accounts tied to one platform. Once compiled from breaches, phishing, or malware sources, these lists get repackaged, renamed, and reshared across Telegram channels for years, which is why a 2023 leak can still be circulating well into 2026.

Check If You Are Affected

HEROIC's free breach scanner checks your email address against more than 400 billion leaked records, including older domain-specific combolists like this Rambler.ru base. If your address matches, changing that password now closes an exposure that may have been open for years.
