CryptogoL12 Leak Exposes 5,346 Logins That Could Unlock More

The "CryptogoL12 15" Stealer Log Uploaded to Telegram

HEROIC analysts identified a stealer log named "CryptogoL12 15" that a Telegram user uploaded on 24-Jul-2026. The file contains 5,346 records made up of email addresses, plaintext passwords, and the URLs those credentials were captured from.

Why the "CryptogoL12 15" Log Is Dangerous

This log is dangerous less because of any one account and more because of how far a single leaked password can travel. Since the passwords are stored in plaintext and matched to specific URLs, an attacker can log into the original account instantly, then use that same password to try logging into other services the same person likely uses, from email to shopping to banking.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs identifying the exact site each login belongs to

Why This Matters

Anyone in this log faces an immediate account takeover risk on the site tied to their leaked credentials. The bigger danger is the chain reaction that follows: because so many people reuse the same password across multiple accounts, one exposed login from this list could give an attacker a way into email, financial, or shopping accounts that were never part of the original breach.

How Stealer Logs Work

Stealer logs come from malware that infects a device and quietly copies whatever the browser has saved, including stored passwords, autofill data, and site URLs. The malware sends this information back to the attacker as a single file, which then gets shared or sold, often through Telegram channels like the one this log surfaced on.

Check If You Are Affected

Because one leaked password can put more than one account at risk, it is worth checking your exposure directly. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including stealer logs like this one, and tells you right away if you were affected. Run a free scan and update any passwords it flags, especially ones you have reused elsewhere.
