The mansory 4 Dump: 1.6 Million Stolen Passwords Just Surfaced

In December 2025, HEROIC analysts identified a large stealer log file named "mansory 4" circulating on Telegram. The file contained 1,600,184 records, each pairing an email address with a plaintext password and the login URL it was used on, all harvested from infected devices.

Why This Is Dangerous

With over 1.6 million records, this is one of the larger stealer logs HEROIC analysts have tracked recently. Every record already includes a working email, an unencrypted password, and the exact site it unlocks, so attackers can start logging into accounts immediately, with no cracking required.

What Was Exposed

• Email addresses tied to a wide range of online accounts
• Plaintext passwords stored with no encryption
• Login URLs showing exactly which site each password unlocks

Why This Matters

At this scale, the risk extends far beyond the original 1.6 million accounts. Reused passwords let attackers run credential stuffing attacks across banking, shopping, and social media platforms, and a single successful login can lead to full account takeover or financial fraud.

How the mansory 4 Stealer Log Was Built

Stealer malware infects large numbers of devices at once, silently copying saved browser passwords and the matching login URLs, then sending everything back to whoever controls the malware. A file this size, like "mansory 4," is typically compiled from many infections combined into one large batch and shared on Telegram.

Check If You Are Affected

With over 1.6 million records in a single file, the odds that your information is included are far from small. HEROIC's free breach scanner checks your email against more than 400 billion leaked records, so you can find out immediately and change any exposed passwords before they're used against you.
