How 35,962 Logins Ended Up in the 36K Mixed Domains Leak

On 23 March 2026, a stealer log titled 36K Mixed Domains turned up on Telegram, holding 35,962 records collected from a wide spread of websites. Each entry pairs a stolen email address with a plaintext password and the exact URL the credentials were used on.

Why a Leak Spanning So Many Different Sites Is Dangerous

Unlike a breach tied to one company, this log pulls logins from dozens of unrelated domains all at once, banking portals, shopping accounts, email providers, and more. That mix gives an attacker far more places to try their luck, since a single victim's stolen password might unlock several completely different accounts.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the sites tied to each login

Why This Matters

A plaintext password next to a real email is everything an attacker needs for credential stuffing, where the same pair gets tried across many accounts in bulk. When it works, victims can face account takeover, financial fraud, or identity theft that spreads accross more than one account at a time.

How This Stealer Log Was Likely Collected

The name 36K Mixed Domains points directly to how it happened. Infostealer malware infects a single device, then quietly scrapes every saved password sitting in the browser, regardless of which site it belongs to. Someone accidently downloading a cracked program or fake update is often all it takes. Once collected, the mixed haul of logins gets bundled together and shared or sold on Telegram.

Check If You Are Affected

Since this log touches so many different services, it's worth checking more than one account. HEROIC's free breach scanner checks your email against more than 400 billion leaked records, including this 36K Mixed Domains log, so you can find out in seconds where you stand.
