Check If Your Login Is in the HUNTER_ULP Leak of 5.8M Logins

In late September 2025, a threat actor operating on Telegram uploaded a fresh credential dump called HUNTER_ULP PRIVATE 26-09-2025 3, and our team confirmed it contains 5,830,044 individual records. These are not old, recycled passwords from some ancient breach. This is a stealer log, meaning the data was pulled directly off infected machines, wich makes it especially fresh and dangerous.

Why This Is Dangerous

Stealer logs work differently than a typical database leak. When a computer gets infected with credential-stealing malware, the malware doesn't just grab one password, it grabs everything saved in the browser at once. That means email logins, banking portals, social media, and random shopping sites all get scooped up in one shot and bundled together for sale or free distribution on Telegram channels like this one.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs of the sites the credentials belong to
• 5,830,044 total records exposed

Why This Matters

Because the passwords in this leak sit in plaintext, anyone who downloads the file doesn't need to crack or decrypt a single thing. They can just copy and paste the credentials straight into a login page. If you reuse passwords across multiple accounts, which a lot of people still do, one leaked password can unlock your email, your bank, and your work accounts all at once.

How Stealer Logs Work

Stealer malware usually sneaks onto a device through a cracked software download, a fake browser update, or a malicious attachment. Once it is running, it quietly copies saved passwords, cookies, and autofill data from the browser and sends everything back to the attacker. Victims often have no idea this occured until their accounts start behaving strangely or they get locked out completely.

Check If You Are Affected

You do not have to guess whether your information is sitting inside this dump or another one just like it. HEROIC runs a free breach scanner that checks your email against a database of more than 400 billion leaked records, including logs like this one. The search takes seconds, and if something turns up you will know exactly which passwords to change imediately.
