The CryptogoL12 Stealer Log Quietly Surfaced With 7,170 Logins

HEROIC analysts identified a stealer log titled "CryptogoL12," uploaded to a Telegram channel on July 23, 2026. The file contains 7,170 records made up of endpoints, email addresses, API hosts, and plaintext passwords.

Why This Is Dangerous

This data quietly surfaced without the fanfare of a major, publicly disclosed breach, which is exactly how stealer logs usually spread. Each record ties a plaintext password to the specific endpoint or API host it unlocks, giving an attacker a direct path into a working account.

What Was Exposed

• Email addresses
• Plaintext passwords
• Endpoint and API host URLs

Why This Matters

Because stealer log data comes from infected devices rather than an old database, it tends to reflect passwords that were still in use at the time of capture. That makes account takeover and credential stuffing attempts more likely to succeed, and gives affected users less time to react before damage is done.

How Stealer Logs Work

Stealer malware infects a device, often through a malicious download or cracked software, then silently harvests saved browser passwords, cookies, and autofill data before sending it to the attacker. The stolen data is bundled into a "log," like this CryptogoL12 file, and sold or shared soon after.
