3.1M URL Log Pass Leak: How a Telegram Upload Exposed 2,635,911 Logins

A file called 3.1M URL LOG PASS - TXT CLOUD landed on a Telegram channel on November 3, 2025, and inside it were 2,635,911 records of emails, plaintext passwords, and the exact URLs those credentials belong to. This is one of the more straightforward stealer logs HEROIC has come across recently, and it shows just how easily this kind of data moves from an infected laptop to a public download link.

Why This Is Dangerous

What makes this leak dangerous isn't just its size, it's the fact that every entry pairs three pieces of information together: who you are, what your password is, and where it works. There is nothing left for an attacker to figure out. Automated tools can run through all 2.6 million lines in minutes, quietly testing which accounts still work.

What Was Exposed

• Email addresses linked to individual accounts
• Plaintext passwords stored without any encryption
• URLs identifying the specific sites the logins unlock
• 2,635,911 total records in the leaked file

Why This Matters

A leak this size doesn't happen because one company got hacked, it happens one infected device at a time, across thousands of seperate computers, until the collected data gets bundled together and sold or shared. That means the victims here span countless websites and services, not just one, wich makes it harder for any single company to warn everyone affected.

How This Kind of Breach Happens

It usually starts small. Someone downloads a cracked piece of software, clicks a bad link, or installs a fake browser update, and a piece of infostealer malware quietly lands on their machine. From there, the malware combs through saved browser data, pulling out every stored password, cookie, and autofill entry it can find. That stolen information gets packaged into a log file and shipped off to a server the attacker controls, then eventually shows up for sale or free download exactly like this.

Check If You Are Affected

If you have ever saved a password in your browser, it is worth checking whether your information is sitting in a file like this one. HEROIC's free breach scanner searches over 400 billion leaked records, including stealer logs, so you can find out in seconds and take action before someone else does.
