Is Your Password in the “cl” Stealer Log? 6,829 Exposed

On January 29, 2023, a stealer log file simply named "cl" was uploaded to a Telegram channel that trades stolen login data. It contains 6,829 records taken from malware-infected devices, each one pairing an email address with a plaintext password and the URL where that password was used. If you've ever had your browser save a password on a device that later picked up malware, a file like this is exactly how your credentials end up online.

Why You Should Take the "cl" Leak Personally

It's easy to read about a breach and assume it doesn't apply to you, especially when the file has a name as generic as "cl." But stealer logs don't discriminate. They collect whatever was saved on an infected device at the time of infection, which means your email and password could be sitting in this file right now without your knowledge, waiting for someone to test them against your other accounts.

What's Inside the File That Might Include You

• Email addresses
• Plaintext passwords, exactly as typed or saved
• URLs showing which accounts each password unlocks

Why This Should Change What You Do Next

If your credentials are in this file, anyone who downloads it can log into the account listed next to your email immediately, no cracking required. From there, they'll likely try that same password on your other accounts through credential stuffing, since most people reuse passwords across multiple sites. That's how a single leaked entry turns into a full account takeover, identity theft, or a drained bank account.

How Your Information Could End Up in a File Like "cl"

Stealer logs come from infostealer malware, malicious software that runs quietly in the background of an infected device and copies every saved password, autofill entry, and browser session it can find. That stolen data is packaged into files like "cl" and distributed on Telegram, often within days of the original infection. This isn't a breach of a company's servers. It's a direct copy of what was saved on someone's personal device.
