The ‘No’ Combolist Leak Exposes 46,010 Email and Password Pairs

HEROIC analysts found a combolist uploaded to a Telegram channel on July 20, 2026 under the sparse filename "no," giving almost no indication of its origin. Despite the unhelpful name, the file itself contains 46,010 records, each pairing an email address with a plaintext password and the URL the login was captured from. Why This Is Dangerous: A vague filename does not make the data inside any less real. These are still working combinations of an email address, a plaintext password, and the site each was used on, meaning an attacker can attempt direct logins without needing to know anything else about where the data came from. What Was Exposed: Email addresses. Plaintext passwords, stored with no protection. URLs showing which site or service each set of credentials belonged to. Why This Matters: With over 46,000 records in one file, even a small percentage of reused passwords translates into a meaningful number of accounts an attacker could break into through credential stuffing. From there, a single compromised login can open the door to email takeover, financial fraud, or identity theft. How a Combolist Like This Gets Made: Files with generic or throwaway names like this one are common on Telegram, often assembled quickly from stealer malware logs or older breach data and uploaded without much documentation, which makes them harder to trace back to a single source but no less dangerous to the people whose credentials are inside. Check If You Are Affected: HEROIC's free breach scanner checks your email against more than 400 billion exposed records, including unlabeled files like this one that would otherwise go unnoticed. Run a scan to see if your login is part of this leak.
