10,851 Leaked Logins Could Fuel Widespread Account Takeover

A Fresh Combo List Hits Telegram This Summer

On July 14, 2026, HEROIC analysts spotted a newly uploaded file titled "11.6K Mix Combo list Full Valid" on a Telegram channel. Despite the "11.6K" name, the verified file contains 10,851 records pairing email addresses with plaintext passwords and the URLs those logins were used on.

Why This Is Dangerous

Because this list surfaced only recently, the credentials inside it are more likely to still be active. The "Full Valid" label means the person who posted it has already tested the logins and confirmed they work, which means anyone who grabs the file can start using the accounts immediately, with no waiting and no guessing required.

What Was Exposed

• Email addresses (mixed providers)
• Plaintext passwords
• Associated login URLs

Why This Matters

A "mix" combo list pulls emails from many different providers and services rather than just one. That variety makes it especially useful for credential stuffing, since attackers can test the same email and password pair against banking sites, shopping accounts, and social platforms all at once. Reused passwords turn a single leaked line into a chain of account takeovers, and the fresher the list, the higher the odds those chains still work.

How Combo Lists Move From Malware to Telegram

Most combo lists like this one begin as logs collected by information-stealing malware installed on victims' computers, which quietly harvests saved browser passwords. Sellers then filter, verify, and repackage this stolen data into "combo lists" for quick resale or free distribution in Telegram groups, often within days or weeks of the original infection.

Check If You Are Affected

Given how recently this list appeared, it is worth checking sooner rather than later. HEROIC's free breach scanner checks your email against more than 400 billion leaked records, including recent combo lists like this one, so you can act fast if your credentials were exposed.
