The Rambler.ru Leak Exposed as Many Accounts as a Small Town

On June 2, 2026, HEROIC analysts identified a combolist uploaded to Telegram containing 3,400 records tied to Rambler.ru, a major Russian web portal and email service. Each record paired an email address with a plaintext password and the URL the login was associated with. Why This Is Dangerous: To put 3,400 accounts in perspective, that's roughly the population of a small town, all with working login credentials circulating in plaintext on Telegram, with no cracking or decryption needed for an attacker to use them. What Was Exposed: The file contains email addresses, plaintext passwords, and the URLs each login was tied to. Why This Matters: Rambler.ru accounts often serve as a primary email address, which means a compromised login can be used to reset passwords on other connected services. If any of these 3,400 people reused their password elsewhere, those accounts, from banking to social media, are exposed to the same credential stuffing risk. How This Combolist Was Likely Built: Combolists tied to a specific email provider, like this Rambler.ru file, are usually built by filtering older breach data or stealer malware logs down to accounts on that domain, then bundling the result for distribution on Telegram. Check If You're Affected: If you have a Rambler.ru account or reuse the same password across different sites, HEROIC's free breach scanner searches more than 400 billion leaked records so you can confirm what's exposed and update any at-risk credentials.
