12,962 Passwords From the Logs_3 June Dump Just Surfaced on Telegram

HEROIC analysts found a stealer log file uploaded to a public Telegram channel on June 3, 2025, labeled Logs_3 June. The file contained 12,962 records made up of email addresses, plaintext passwords, and the URLs of the login pages those credentials belong to.

Why This Is Dangerous

Because the passwords in this file are stored in plaintext and matched directly to a URL, an attacker does not need to guess, crack, or decrypt anything. With nearly 13,000 records in one file, an attacker can automate login attempts across thousands of accounts at once, going straight to each exact login page and trying the exact password listed next to it.

What Was Exposed in the Logs_3 June Upload

• Email addresses
• Plaintext passwords
• URLs of the affected login pages

Why This Matters for the 12,962 People Affected

A leak of this size gives attackers a large pool of working credentials to run through credential stuffing tools, automatically testing each email and password pair against other websites. Anyone in this file who reused a password elsewhere faces a real risk of account takeover, financial fraud, and identity theft.

How a Stealer Log Like Logs_3 June Gets Made

Stealer logs are produced by malware that infects a device through a fake download, cracked software, or a phishing link, then quietly copies the passwords and site data saved in the victim's browser. That harvested information is bundled into a log file and shared or sold, often through Telegram channels exactly like the one where this file appeared. Because the data comes directly from the browser, the passwords collected are typically the ones the victim was using at the time of infection.
