CryptogoL12 Leak Bigger Than Most: 29,633 Records Exposed

Most stealer logs that circulate on Telegram top out at a few thousand entries. CryptogoL12, posted May 22, 2026, blows past that with 29,633 stolen credential records in a single file.

Why This Is Dangerous

Scale changes the math for attackers. A file this size gives them enough volume to run wide credential stuffing campaigns rather than picking off individual targets, and every password inside is stored in plaintext wich makes each attempt instant.

What Was Exposed

• 29,633 stolen credential records
• Email addresses connected to each session
• Plaintext passwords with no protection layer
• URLs revealing which accounts each password unlocks

Why This Matters

When a leak this size occured, it typically doesn't stay contained to one Telegram channel for long. Copies spread to other groups and marketplaces within days, multiplying the number of people who have access to the same 29,633 records.

How Stealer Logs Work

CryptogoL12 follows the standard stealer log pattern, malware infects a device through a malicious download or compromised installer, then harvests saved browser passwords and session cookies before sending everything to the attacker's collection server. The size of this dump suggests the malware behind it had a wide distribution before this file was compiled.

With almost thirty thousand records at stake, it's worth taking two minutes to check your exposure. HEROIC's free scanner covers more than 400 billion (400B+) leaked records, so you can see immediately whether CryptogoL12 touched your accounts.
