The Telegram Stealer Log: 12,924 Stolen Email and Password Records Leaked

In April 2023, a Telegram user uploaded a stealer log file containing 12,924 records compromised from infected endpoints across the United States. The leaked archive included email adresses, plaintext passwords, and URLs harvested directly from victims' devices by malware. This type of breach is particularly dangerous because the data is pulled live from active sessions, meaning credentials are captured the moment they are used.

Why This Is Dangerous

Stealer logs are not ordinary data breaches. Unlike database hacks where encrypted passwords might offer some protection, stealer logs capture credential data in real time from infected machines. By the time this archive surfaced on Telegram, every password in it was already plaintext and ready to use. Attackers can immediately attempt account takeovers, credential stuffing attacks, and identity theft without any additional cracking steps.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (sites and services accessed by victims)

Why This Matters

With 12,924 records exposed in a single Telegram upload, this breach represents one entry point in a much larger ecosystem of stealer log sharing. These logs are traded freely in criminal comunities and can be repackaged, resold, or combined with other datasets to build detailed profiles on victims. If your email appears in this breach, your password for one or more services may already be in the hands of malicious actors.

How Stealer Log Breaches Work

Stealer malware typically infects devices through phishing emails, malicious downloads, or comprimised software. Once installed, it silently harvests saved passwords from browsers, email clients, and applications. It also logs URLs visited and auto-fill data. The collected data is bundled into archive files and uploaded to criminal marketplaces or messaging platforms like Telegram, where they are distributed to other threat actors within hours of collection.

Check If You Are Affected

HEROIC's free scanner searches across more than 400 billion records to tell you if your email or password appeared in this breach or thousands of others. If you were exposed, you'll get clear guidance on what to change and how to protect yourself going forward. Don't wait for attackers to use your data against you.
