How Malware Led to 216,991 Stolen Logins in Mansory 2

HEROIC has identified the second installment of the "Mansory" stealer log series on Telegram, containing 216,991 compromised records. This collection was assembled from credentials harvested by infostealer malware across thousands of infected devices, and it pairs plaintext passwords with email addresses and the URLs of services where those credentials were entered.

Plaintext Exposure Eliminates Any Safety Buffer

The 216,991 passwords in this Mansory 2 dump are stored in plaintext—unencrypted, unmasked, and immediately readable. There is no cracking step, no decryption time, and no barrier for attackers. Once downloaded, these credentials can be fed into automated attack tools and tested against live services in a matter of minutes.

What Was Exposed

• Email Addresses – Account identifiers that serve as both login names and phishing targets
• Plaintext Passwords – Raw, unprotected credentials stolen from browser storage
• URLs – The specific login pages where each set of credentials was captured

The Domino Effect of Stolen Credentials

Each record in this dump represents a potential chain reaction. Attackers use credential stuffing to test stolen login pairs against popular services—email platforms, banks, social networks, and cloud storage. Because most people reuse passwords, a single successful match can unlock access across a victim's entire digital footprint. With 216,991 records, the potential for cascading damage is significant.

Tracing the Path from Infection to Leak

The journey of these credentials followed a well-established pattern. First, infostealer malware—likely variants such as Redline or Vidar—infected victim devices through malicious downloads or phishing links. The malware silently extracted saved passwords from every browser on the system. These credentials were then packaged into structured log files, aggregated into the Mansory 2 collection, and distributed through Telegram channels where criminals buy, sell, and share stolen data.

Check If Your Credentials Were Exposed

HEROIC's free breach scanner searches over 400 billion compromised records to check whether your email or domain appears in this Mansory 2 stealer log or any other documented data breach. Do not assume you are safe—search now, rotate any compromised passwords, and enable multi-factor authentication on all your critical accounts.
