How a Small Telegram Combolist Leaked 2,523 Login Pairs

HEROIC analysts found a combolist called 2520x MIX HITS uploaded to a Telegram channel on July 13, 2026. The file name suggests around 2,520 entries, and the verified count comes in close at 2,523 records, each combining an email address or username with a plaintext password and a URL. Why This Is Dangerous: Files like this usually start small. A trader collects working logins, often assembled from older leaked databases or stealer log output, filters out the dead accounts, and packages the survivors as hits, meaning confirmed, working credentials. That filtering step is exactly what makes a small file like this one worth taking seriously. What Was Exposed: - Email addresses and usernames - Plaintext passwords - URLs tied to each login Why This Matters: A file described as hits implies these 2,523 logins were already tested and found to work at the time they were posted. Attackers use lists like this directly for credential stuffing, feeding each pair into login forms across popular sites. If your password shows up here and you use it elsewhere, that account is at real risk of takeover or fraud. How a Combolist Like This Works: A combolist named MIX HITS typically means someone merged multiple smaller sources of stolen credentials, then ran automated checks to weed out logins that no longer worked, keeping only the ones confirmed as hits. That curation makes the remaining file smaller but more dangerous per record than a raw, unchecked dump. Check If You Are Affected: You don't need to track down a Telegram channel to find out if you're in a file like this. HEROIC's free breach scanner checks your email against more than 400 billion leaked records, including combolists like 2520x MIX HITS, so you can act before someone else does.
