The MOX COMBO 3 Dump Contains Exactly 3,686 Email and Password Pairs

In June 2026, HEROIC analysts documented a combolist labeled MOX COMBO 3 shared by a Telegram user. The file held exactly 3,686 records, each combining an email address, a plaintext password, and the URL the credentials were captured from. Why the MOX COMBO 3 leak is dangerous: every one of the 3,686 pairs in this file is ready for immediate use. There's no encryption to break and no guesswork involved, an attacker simply needs to try each email and password combination against the listed site or against other popular services, hoping the victim reused the same password elsewhere. What was exposed in MOX COMBO 3: email addresses, plaintext passwords, and URLs tied to each set of credentials. Why this matters even at a smaller scale: a file of 3,686 records may look small next to breaches involving millions, but every single record represents a real person whose login details are now circulating. Credential stuffing tools don't care about volume, they'll test each pair automatically, meaning even a modest combolist like this one can lead to account takeover, identity theft, or financial fraud for the people involved. How a combolist like MOX COMBO 3 gets made: combolists are assembled by pulling email and password pairs from previous breaches, malware infections, or phishing campaigns, then combining them into a single, organized file. The 3 in the file's name suggests this is part of a series, meaning the same source may have already released, or may still release, related batches of stolen credentials. Check if you are affected: you can check whether your email address appears in the MOX COMBO 3 leak or any other exposure using HEROIC's free breach scanner.
