CryptogoL12 Breach: 36,568 Passwords and Emails Exposed Online

In July 2026, HEROIC analysts discovered a stealer log file named "CryptogoL12" posted to a Telegram channel. The file contains 36,568 records, each pairing an email address with a plaintext password and the login URL the credential was taken from.

Why the CryptogoL12 Leak Is Dangerous

CryptogoL12 was not stolen from a company's servers. The data was harvested directly from infected computers by information-stealing malware, which quietly copies saved browser passwords and sends them to whoever controls the operation. Because each record already ties a specific website to a working email and password, an attacker can log straight in without guessing or cracking anything.

What Was Exposed

• Email addresses
• Plaintext passwords
• Login URLs (the exact site each credential unlocks)

Why This Matters

Because the passwords in this file are stored in plaintext and already matched to their websites, they are immediately usable for credential stuffing and account takeover. Anyone caught up in the CryptogoL12 leak risks losing access to email, shopping, or financial accounts, particularly if the same password is reused on more than one site.

How Stealer Log Leaks Like CryptogoL12 Happen

Stealer logs come from malware infections rather than hacked databases. A victim installs a cracked program, clicks a phishing link, or downloads a fake update, and hidden malware then silently harvests every saved username, password, cookie, and autofill entry from the browser. The results from many infected devices are bundled into a single log file and shared or sold on Telegram channels and dark web forums, which is exactly how CryptogoL12 surfaced.
