The Mansory 1 Telegram Log Put 1.5 Million Stolen Email and Password Pairs Online

HEROIC analysts confirmed that in April 2026, a Telegram user operating under the alias mansory 1 uploaded a stealer log file exposing 1,581,415 records containing email addresses, plaintext passwords, and the URLs of the exact sites where each credential was captured. The log was compiled from endpoints infected with infostealer malware, which harvested saved browser credentials and transmitted them back to the attacker before being packaged and distributed through Telegram channels accessible to any subscriber.

Why This Is Dangerous for Anyone Caught in This Breach

With 1.5 million plaintext password and email pairs now in criminal hands, the threat is immediate and requires zero technical skill to exploit. Attackers do not need to crack anything -- the passwords are already in clear text. The inclusion of captured URLs means each credential is paired with its target site, so criminals know exactly where to try each login. Victims whose passwords appear in this log face account takeover on every service where they reused that password, often without any notification from the affected platforms. The scale of over 1.5 million records also makes this log attractive for resale on darknet forums, extending the exposure window for years.

Mansory 1 Stealer Log: Data Types Exposed in This Breach

• Email Addresses -- used as usernames across most online services, enabling broad targeting of victims
• Plaintext Passwords -- fully decrypted, immediately usable credentials requiring no additional processing
• URLs -- the specific websites from which credentials were harvested, giving attackers a ready-made attack map

Credential Stuffing, Account Takeover, and Financial Fraud From Stealer Logs

Once a stealer log of this size circulates on Telegram, automated credential stuffing tools can test all 1.5 million email and password pairs accross thousands of websites within hours. Any account where the victim reused the same password becomes instantly vulnerable. Attackers prioritize high-value targets: online banking, cryptocurrency exchanges, PayPal, Amazon, and corporate email accounts. A successfull account takeover on a business email account can lead to invoice fraud, wire transfer redirection, and data extortion. Identity theft follows when attackers combine email access with personal data to open credit lines, file fraudulent tax returns, or impersonate victims in further social engineering attacks. Financial losses from a single stealer log campaign can reach millions of dollars across the affected victim pool.

How Infostealer Malware Turns Your Browser Into a Credential Vault for Criminals

Infostealer malware is engineered to silently drain the credential storage systems built into modern browsers. When you save a password in Chrome, Firefox, or Edge, it is stored in an encrypted local database. Infostealer malware running on your device decrypts this database using the same operating system keys the browser uses, then extracts every saved username and password alongside the associated URL. It does the same for cookies, which can be used to bypass two-factor authentication by hijacking an already-authenticated session. The entire process happens invisibly in the background and is typically complete within seconds of infection. The harvested data is then exfiltrated to a command-and-control server or directly uploaded to a Telegram channel, where it is distributed as a log file. Victims recieve no system alert and no breach notification because the compromise happend on their own device rather than at a company's servers.
