Analysts Flag the MIX_1 Combolist After 5,836 Credentials Surface

HEROIC analysts flagged a combolist called MIX_1, uploaded to a Telegram channel and dated November 10, 2024. The file contains 5,836 records, each pairing an email address with a plaintext password and the URL each login was used on. Why This Is Dangerous: The name MIX_1 signals that this file blends credentials from multiple sources into one list. That mix makes it harder to trace back to a single origin, but just as dangerous, since every entry is still a working email and password combination. What Was Exposed: Each of the 5,836 records in this file shares the same three fields. - Email addresses - Plaintext passwords - URLs identifying where each login was used Why This Matters: Mixed combolists like this one are popular with attackers precisely because they cast a wide net across different services and user bases. Anyone whose email appears here faces the same core risks: credential stuffing, account takeover, and potential financial fraud if a compromised account touches money. How a Combolist Like This Works: A mixed combolist, often labeled MIX or similar, is created by merging data pulled from several smaller breaches, stealer logs, or phishing hauls into a single file. Combining sources this way lets sellers offer a bigger, more varied list without needing a single large breach behind it.
