The 330k URL LOGIN PASS Leak Means Someone Could Access Your Passwords

On 26-May-2026, HEROIC analysts identified a combolist named "330k URL LOGIN PASS" after it was uploaded by a Telegram user. Once duplicates were removed, the file contained 108,270 confirmed records pairing email addresses with plaintext passwords and the website URLs each login belongs to. Why This Is Dangerous Because the passwords are stored in plaintext and matched directly to a login URL, an attacker does not need to guess where to use a stolen credential. The file effectively hands over a ready-made list of website, username, and password combinations. If any of the 108,270 accounts reused a password on another site, an attacker can log in immediately, with no additional work required. What Was Exposed Email addresses Plaintext passwords Website URLs matched to each login Why This Matters A file this size gives attackers enough volume to run large-scale credential stuffing campaigns, automatically testing each email, password, and URL combination against the site it belongs to. Because the URLs are already attached, the process is faster and more effective than a random guessing attack. Anyone in this file who reused a password across accounts is exposed to account takeover, identity theft, and financial fraud. How a URL-Login-Password Combolist Is Built This type of combolist, often labeled "URL LOGIN PASS," is assembled by combining stolen credentials with the specific web address they were used on. The source material typically comes from older data breaches, phishing pages, or malware that logs credentials as they are typed. Telegram channels are a common distribution point for these files because they let sellers reach large numbers of buyers quickly while staying difficult to trace. Files are frequently named with a rounded number, like "330k" here, to advertise their apparent size, even though the confirmed, deduplicated count often differs, as it does in this case at 108,270 records. Check If You Are Affected With 108,270 accounts exposed in this leak, it is worth taking a moment to check whether your email is included. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including combolists like this one, and tells you immediately if you have been exposed.
