33,658 Records Leaked: Inside the 34K Mix Telegram Dump

Somewhere in the flood of files that move through Telegram every day, one labeled 34K Mix uploaded by a Telegram User stood out for a bad reason. It held 33,658 records of stolen credentials, all harvested from devices that had been infected with information stealing malware. The leak occured in late February 2026, and like most stealer logs, it slipped out with zero fanfare.

Why This Is Dangerous

What makes this kind of leak so risky is the format the data comes in. There is no encryption to break, no hash to crack, the passwords are already in plaintext form. That means the barrier between a criminal finding this file and actually logging into someone's account is close to zero. It is a seperate category of danger from a leak where passwords at least need to be decoded first.

What Was Exposed

• 33,658 total records
• Email addresses
• Plaintext passwords
• URLs linked to each set of stolen credentials

Why This Matters

Every record in this file represents a real person who had no idea their browser data was being siphoned off in the background. Because the URLs travel along with the login pairs, attackers can sort the data by website type, going straight after banking portals, email providers, or shopping accounts where reused passwords are common.

How Stealer Logs Work

Infostealer malware typically hides inside pirated software, fake browser updates, or malicious ads. Once it runs on a victim's computer, it digs through saved browser passwords, cookies, and autofill fields, then packages the results into a log file. That file often gets uploaded to a marketplace or, as with this one, dropped directly into a Telegram channel where anyone can download it for free.

Check If You Are Affected

If you want to know whether your own information is sitting in a file like this one, HEROIC offers a free scanner that checks your email against a database of more than 400 billion breached records. It only takes a moment, and it beats waiting to find out through a locked account or a suspicious login alert.
