One Telegram Upload. 70,147 Records. The Mexico 3 Combolist Leak.

In August 2022, HEROIC analysts identified a combolist titled "Mexico 3" uploaded to a Telegram channel by an anonymous user. The file contained 70,147 records pairing email addresses with plaintext passwords and the URLs those credentials were used on. Why the Mexico 3 Combolist Is Dangerous: with over 70,000 email and password pairs stored in readable text, this file gives attackers a ready-made list to test against banks, email providers, and shopping sites. No hacking skill is required, just automated software that tries each pair across hundreds of login pages until one works. What Was Exposed: email addresses, plaintext passwords, and the URLs associated with each login. Why This Matters: a combolist of this size means tens of thousands of people could have a working password sitting in a criminal's toolkit. If any of those passwords were reused elsewhere, attackers can move from one compromised account to another, turning a single leaked password into a chain of account takeovers, financial fraud, or identity theft. How a Combolist Works: combolists are built by combining credentials from older breaches, phishing campaigns, and malware infections into one large file, rather than coming from a single new hack. Criminals then feed the list into automated tools that attempt each login across many websites at once. The Mexico 3 combolist follows that same structure, packaging 70,147 email and password combinations with the URLs they were paired to. Check If You Are Affected: HEROIC's free breach scanner checks your email against more than 400 billion leaked records, including large combolists like Mexico 3. A quick scan tells you if your credentials are part of this exposure so you can update your passwords before they are used against you.
