Credentials for Sale: The 5K UHQ Combolist Leaked 4,949 Accounts

In January 2023, HEROIC analysts identified a Telegram upload called 5k UHQ Combolist US Good hits, containing 4,949 records of email addresses, plaintext passwords, and the URLs tied to each credential pair. UHQ stands for ultra high quality, and good hits indicates the uploader had already confirmed these US-based accounts were active. Why is this dangerous? Because this list is marketed as pre-verified, an attacker can skip the step of testing which credentials still work and go straight to using them. Combined with plaintext passwords and the matching login URL, this file gives criminals a ready-to-use list of nearly 5,000 confirmed accounts. What was exposed: US-based email addresses, plaintext passwords, and URLs linked to each credential pair. Why this matters: verified combolists like this one command a premium among criminals precisely because they skip the guesswork. Every confirmed hit in this file represents a real account that can be used for credential stuffing on other sites, financial fraud, or full account takeover if the password was reused anywhere else. How this combolist was built: sellers build UHQ good hits lists by running large batches of stolen credentials through automated checker tools that confirm which logins are still active, then packaging only the confirmed working entries for sale. This process is why files labeled this way tend to be smaller than raw combolists but far more dangerous per record. Check if you are affected: because every entry in this file was confirmed working at the time it was compiled, checking your exposure now matters. HEROIC's free breach scanner checks your email against more than 400 billion leaked records, including verified lists like this one, so you can update your password before it is used against you.
