CryptogoL12 Stealer Log: 2,377 Plaintext Passwords Exposed

CryptogoL12 Stealer Log Uploaded to Telegram

HEROIC analysts identified another stealer log labeled CryptogoL12, uploaded to a Telegram channel on 24 July 2026. The file contains 2,377 records taken directly from infected devices, combining email addresses, plaintext passwords, and the URLs of the accounts those credentials open. This batch appears to be part of a larger CryptogoL12 series, with multiple related files circulating around the same time.

Why This Stealer Log Is Dangerous

Because CryptogoL12 pairs each password with the exact site it was used on, an attacker doesn't need to guess where a stolen credential works, they already know. That means every one of the 2,377 records can be tested as a direct login attempt, with no cracking, no phishing, and no extra hacking against the affected sites required.

What Was Exposed

• Email addresses tied to individual accounts
• Plaintext passwords for those accounts
• URLs identifying exactly which sites the credentials belong to

Why This Matters

Account takeover is the immediate risk, since attackers have direct login access to any credential that's still valid. Credential stuffing is the risk that extends further: since many people reuse the same password across different accounts, a login exposed in CryptogoL12 could just as easily open a victim's email, banking, or shopping account on a completely different site than the one it was stolen from.

How Stealer Logs Work

Stealer logs are the product of malware that quietly infects a device, often through a pirated download, fake software crack, or malicious attachment, and then harvests saved browser passwords along with the exact websites they belong to. The stolen data is packaged into a file and distributed, in this case uploaded to a Telegram channel as one of several CryptogoL12 batches, giving buyers a growing pool of working credentials.
