The Mansory 2 Leak Contains Exactly 1,743,805 Stolen Login Credentials

HEROIC analysts identified a stealer log file uploaded to a Telegram channel on 15 December 2025, labeled "mansory 2" by the person who posted it. The file contains 1,743,805 records, each one pairing an email address with a plaintext password and the URL of the account it belongs to. At nearly 1.75 million entries, this is one of the larger stealer log uploads HEROIC's dark web monitoring has flagged in recent weeks.

Why This Is Dangerous

Every one of the 1,743,805 credentials in the mansory 2 file came from malware sitting on someone's computer, quietly capturing logins as they were typed or auto-filled. That means these passwords were active and correct at the time they were stolen, not old, expired data pulled from a years-old breach. Combined with the exact login URL, an attacker can automate logins at massive scale, checking millions of accounts in a fraction of the time it would take a human.

What Was Exposed

• Email addresses for 1,743,805 individual accounts
• Plaintext passwords with no hashing or encryption applied
• URLs identifying the exact site or service tied to each login

Why This Matters

A dataset this large turns into a numbers game for cybercriminals. Even if only a small percentage of the 1,743,805 accounts use passwords that are reused elsewhere, that still adds up to tens of thousands of working logins for email accounts, banking portals, and social media. Attackers run these lists through automated credential stuffing tools around the clock, and every successful match can lead to account takeover, financial fraud, or identity theft for the victim.

How a Stealer Log This Size Gets Built

Stealer logs like mansory 2 come from infostealer malware that spreads through fake software downloads, cracked programs, or malicious email attachments. Once installed, the malware harvests every saved password, autofill entry, and session cookie from the victim's browser and quietly sends it back to the attacker's server. Operators then combine logs from thousands of infected devices into a single massive file, exactly how a batch this size, spanning 1.7 million records, gets assembled and sold or shared on Telegram.
