DE 8.13 Telegram Stealer Log Puts 28,522 Passwords at Risk

In March 2023, a threat actor uploaded a stealer log file labeled "DE 8.13" to a Telegram channel, exposing 28,522 records. The file contains email addresses, plaintext passwords, and the URLs those credentials were used on, all pulled from malware-infected devices rather than stolen from any single company's servers.

What Happens Next If This Log Goes Unchecked

Once a file like this circulates on Telegram, it does not stay in one place for long. Copies get passed around, resold, and folded into larger collections used for automated login attempts across hundreds of websites. Every day this data sits unaddressed, the accounts tied to it stay exposed to anyone willing to download the file and try the logins for themselves.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the accounts and sites accessed

Why This Matters

Because the passwords in this file are stored in plaintext, there is no encryption standing between a criminal and a working login. That makes credential stuffing, automatically testing the same email and password pair across many sites, fast and easy to carry out at scale. If you reuse a password anywhere, one exposed login here can lead to a takeover of your email, banking, or shopping accounts, and from there to identity theft or direct financial fraud.

How a Stealer Log Like DE 8.13 Gets Built

Stealer malware typically spreads through cracked software, fake installers, or malicious attachments. Once it lands on a device, it quietly pulls saved passwords, autofill data, and session details straight out of the browser, then packages everything into a log file. Files like this one get labeled with a batch name and number, in this case "DE 8.13," and traded on Telegram channels and dark web marketplaces, often merged with other logs into larger combined lists.

Check If You Are Affected

Do not wait to find out the hard way. HEROIC's free breach scanner checks your email address against a database of more than 400 billion leaked records, including stealer logs like this one, and shows you immediately if you have been exposed. If you find a match, change that password right away, update it anywhere else you reused it, and turn on two-factor authentication wherever it is available.
