CryptogoL12 15: 25,111 Accounts Exposed in Stealer Log

HEROIC found the CryptogoL12 15 stealer log on April 21, 2026, exposing 25,111 records containing email addresses, plaintext passwords, and URLs.

Why the CryptogoL12 15 Breach Is Dangerous

CryptogoL12 15 is the fifteenth installment in an ongoing Telegram stealer log series, representing a sustained criminal operation that regularly publishes batches of stolen credentials. With 25,111 records of URL-paired plaintext passwords, each entry is a targeted credential set harvested directly from a compromised device. The series format indicates a professional operation rather than a one-off leak, increasing the likelihood that fresh credentials continue to be added to future releases.

What Was Exposed in the CryptogoL12 15 Leak

• Email Addresses -- 25,111 user account identifiers stolen during active device sessions
• Plaintext Passwords -- working credentials ready for immediate login attempts
• URLs -- specific websites where each credential was captured and is known to work

Why This CryptogoL12 15 Data Puts You at Risk

Being part of an ongoing series means the CryptogoL12 operation is actively collecting new victims. If your credentials appear in batch 15, they were recently compromised, making the risk of active account exploitation very high. Attackers with access to the full CryptogoL12 series can also cross-reference multiple batches to build comprehensive profiles of victims, increasing the damage potential far beyond a single login attempt.

How Stealer Logs Work

Stealer logs are generated by infostealer malware infections that silently harvest browser-saved passwords, session cookies, and autofill credentials. The data is sent to attacker servers and packaged into numbered series like CryptogoL12, which are sold or freely shared on Telegram. Each batch in the series represents a fresh collection of stolen credentials, allowing buyers to continuously target new victims without needing to conduct their own infections.
