Leaked in 2023: The 100k Userpass Paid Combolist Still Circulates

In May 2023, HEROIC analysts identified a combolist labeled "100k userpass paid" that a Telegram user uploaded, exposing 100,000 records. The data traces back to a leak date of May 7, 2023, and includes email addresses paired with plaintext passwords and URLs, meaning it has been circulating for years before resurfacing. Why This Is Dangerous: This file was originally sold as a paid product, suggesting it was curated and verified before distribution, which typically means the credentials inside are more likely to still work. Because the passwords are in plaintext, they are ready to use the moment someone opens the file. What Was Exposed: - Email addresses - Plaintext passwords - URLs showing which sites or services each login unlocks Why This Matters: A three-year-old leak doesn't mean the risk has passed. People rarely change passwords unless they know they need to, so credentials from 2023 often still work in 2026. Attackers use lists like this for credential stuffing, testing each email and password pair against banking, shopping, and social media accounts, which can lead directly to account takeover and financial fraud. How a Combolist Like This Works: A combolist compiles stolen or leaked email-and-password pairs, sometimes sold as a paid product on underground markets before eventually leaking further and being redistributed for free on Telegram. Buyers and now free downloaders run these lists through automated tools that test each pair against dozens of websites, flagging every successful login for exploitation. Check If You Are Affected: If your credentials haven't changed since 2023, this leak could still put you at risk today. HEROIC's free breach scanner checks your email against more than 400 billion leaked records, so you can find out immediately and update any passwords that are still in use.
