1.1M Stolen Passwords Leaked From Telegram Stealer Log Dump

In October 2025, HEROIC analysts identified a stealer log file circulating on a Telegram channel, uploaded by an anonymous user. The file contained 1,149,003 records pulled straight from infected devices, including email addresses, plaintext passwords, and the exact website URLs each login belonged to. Unlike a typical corporate hack, this data came from malware that quietly recorded everything victims typed into their browsers.

A Late Night Login, A Silent Thief Watching

Picture someone logging into their email at 11pm from their laptop, unaware that infostealer malware is already running in the background. Every keystroke, every saved password, every site they visit gets logged and shipped off to a remote server. Weeks later, that file lands in a Telegram group, packaged and ready for anyone to download and use.

That is exactly what happened here. The uploaded log connects real people to the exact accounts they use, in plaintext, with no encryption standing in the way.

Why This Is Dangerous

Because the passwords are stored in plaintext and matched directly to their corresponding URLs, an attacker does not need to guess or crack anything. They simply open the file and start logging into email accounts, shopping sites, and anywhere else the victim signed in while infected. This is about as low effort as account takeover gets.

What Was Exposed

• Email addresses
• Plaintext passwords
• Corresponding login URLs

Why This Matters

Stealer logs like this one are a favorite tool for credential stuffing. Attackers take the email and password pairs and test them against banking sites, social media, and work portals, betting that people reuse passwords. If even one match succeeds, it can quickly snowball into full account takeover, identity theft, or financial fraud.

How Stealer Log Breaches Work

Stealer malware infects a device, often through a cracked software download, phishing link, or malicious ad. Once installed, it quitely harvests saved browser passwords, autofill data, and session cookies, then sends everything back to the attacker. These logs are then sold or shared in bulk on Telegram and dark web marketplaces, exactly like the one uncovered here.

Check If You Are Affected

If you have ever saved a password in your browser, it is worth checking whether your information appeared in this leak. HEROIC's free breach scanner searches a database of more than 400 billion exposed records to show you instantly if your email or passwords have surfaced online.
