Your Login May Be Exposed: User Pass Part 5 Leak Hit 745,192 Accounts

Your login may already be sitting in a file you have never heard of. HEROIC analysts identified a combolist named "user pass part 5" uploaded to a Telegram channel on December 24, 2022. The file contains 745,192 records, each pairing an email address with a plaintext password and the URL that login was used on. Why This Is Dangerous: With over 745,000 working email and password combinations in one file, an attacker does not need to target you specifically. Automated tools can run through the entire list against major websites, and anyone whose password was reused elsewhere becomes an easy target without ever being singled out. What Was Exposed: Email addresses. Plaintext passwords. URLs identifying the site or service each login was captured from. Why This Matters: At this scale, even a small percentage of reused passwords adds up to thousands of real accounts at risk. This is the exact mechanism behind credential stuffing attacks, where stolen logins from one breach are used to break into completely unrelated accounts, often leading to identity theft or financial fraud. How a Combolist Like This Gets Made: Files labeled as sequential "parts," like this fifth installment, usually come from an uploader who has compiled a much larger set of stolen credentials from stealer malware and older breaches, then released it in batches over time to sustain interest across Telegram channels. Check If You Are Affected: HEROIC's free breach scanner checks your email against more than 400 billion leaked records. With nearly three quarters of a million credentials in this file alone, take a minute to check whether yours is one of them.
