The OK 1 – HADESk Leak Gives Attackers 2,352 Working Logins

HEROIC analysts identified a combolist named "OK 1 - HADESk" uploaded to Telegram on July 22, 2025. The file contains 2,352 records, each combining an email address, a plaintext password, and the URL of the site the credentials belong to. Why This Is Dangerous: With email, password, and destination URL all bundled together, an attacker doesn't need to do any extra work, they can plug each record straight into the matching login page and see immediately which accounts still open. What Was Exposed: - Email addresses - Plaintext passwords - URLs pointing to the exact login pages involved Why This Matters: This kind of ready-to-use format is exactly what fuels credential stuffing attacks. Once an attacker confirms a working login, they can take over the account outright, and if the same password shows up on other services, they can pivot into email, banking, or shopping accounts too, opening the door to identity theft and financial fraud. How a Combolist Like This Works: Files like "OK 1 - HADESk" are usually built by combining data from multiple smaller sources, phishing pages, old breaches, or malware, then formatted so each line is a complete, actionable login attempt. That formatting is what makes combolists more dangerous than raw, unsorted leak data. Check If You Are Affected: Check whether your email shows up in this leak or any of the more than 400 billion other exposed records HEROIC tracks, using HEROIC's free breach scanner. If it does, change that password everywhere you've used it.
