Mansory 10 Stealer Leak: What Hackers Do With 5.6M Logins

On January 12, 2026, a Telegram user uploaded a stealer log collection labeled Mansory 10, exposing 5,593,547 records harvested from malware-infected devices. The trove includes email addresses, plaintext passwords, and the exact URLs tied to each stolen login, making it one of the larger stealer log dumps to surface this year.

What Attackers Can Do With 5.6 Million Logins

A file this size isn't just a list, it's a toolkit. With 5,593,547 email-and-password pairs in hand, an attacker can automate login attempts across thousands of websites at once, testing each stolen credential against banks, email providers, retailers, and workplace accounts to see which ones still work. At this scale, even a small success rate turns into tens of thousands of compromised accounts.

What Was Exposed

• Email addresses - the usernames tied to millions of individual accounts
• Plaintext passwords - stored in readable form, no decryption needed
• URLs - the specific login pages each password was captured from

Why This Matters

Because these credentials were captured straight from infected devices rather than a single company's database, they often still work everywhere else too. Attackers use dumps like this one to power credential stuffing attacks, hijack email and social accounts, drain financial accounts, and build detailed profiles for identity theft. The larger the file, the more attractive it becomes to criminal groups running these attacks at scale.

How This Stealer Log Was Collected

Stealer malware works quietly in the background of an infected computer, pulling saved passwords, autofill entries, and active browser sessions before sending everything back to the attacker in a single log file. Collections like Mansory 10 are built by merging thousands of these individual infections into one master file, which is then sold or given away on Telegram to attract buyers to a seller's other, paid offerings.

Check If You Are Affected

With millions of records involved, there's a real chance your credentials are sitting in this file or another one like it. HEROIC's free breach scanner checks your email against more than 400 billion leaked records, including stealer logs like Mansory 10, so you can find out in seconds and take action before an attacker does.
