2M Private ULP 2 July-26 uploaded by a Telegram User Leaks 1.5M Logins

In June 2026, HEROIC analysts identified a large stealer log circulating on Telegram, uploaded under the label "2M Private ULP." Dated 22-Jun-2026, the file contained 1,485,928 records, each pairing an email address with a plaintext password and the URL of the site that login unlocks.

Why This 1.5 Million-Record Stealer Log Is Dangerous

Scale is what separates this leak from a small, contained incident. With nearly 1.5 million email, password, and URL combinations in one file, an attacker doesn't need to target anyone specifically. They can run the entire list through automated tools and let the software find every account that still works. Because each password is paired with the exact site it opens, there's no guesswork involved: the attacker knows precisely where to try each stolen login.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linked to each set of credentials

Why This Matters

Plaintext passwords mean an attacker doesn't need to crack anything, the login works exactly as it was typed. At this scale, the most immediate risk is credential stuffing: automated attempts to reuse each email and password pair on other popular sites. If any of the 1,485,928 exposed accounts share a password with your email, bank, or shopping account, that account could be logged into without your knowledge, leading directly to account takeover.

How Stealer Logs Work

A stealer log is generated by malware that infects a device and quietly harvests the usernames, passwords, and site URLs saved in a browser, then sends that data back to whoever controls the malware. Because a single infected device can hold logins for dozens of unrelated sites, the resulting file mixes together countless accounts. Files like this one are then packaged, shared, or sold in bulk on platforms like Telegram, where they can circulate widely before most victims ever know their data was taken.

Check If You Are Affected

With over a million accounts in this one file alone, checking your own exposure only takes a moment. HEROIC's free breach scanner searches your email against a database of more than 400 billion leaked records, including stealer logs like this one, and shows you immediately if you were caught up in it. If you were, updating that password right away and enabling two-factor authentication shuts down the easiest path an attacker has into your accounts.
