The CryptogoL12 Stealer Log Could Unlock Your Bank and Email Logins

Another CryptogoL12 Stealer Log Batch Surfaced on Telegram

On August 19, 2026, HEROIC analysts identified a second stealer log file, named "CryptogoL12.26 7," uploaded to a Telegram channel, appearing to be a related batch from the same malware campaign as an earlier log. This file contained 3,803 records, each pairing an email address with a plaintext password and the URL of the login page it was pulled from. Stealer logs like this one capture credentials directly from an infected device's browser, meaning the data is often still current and working.

Why This Is Dangerous

Because every entry links a real email address, a plaintext password, and the exact site the login belongs to, an attacker does not have to guess or crack anything, they simply try the credential and see if it works. A single exposed login rarely stays isolated. Many people reuse the same password for their email, their bank, and their social media accounts, so one leaked credential can potentially unlock several parts of a person's digital life.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs identifying the associated sites or services

Why This Matters

With 3,803 credential pairs in this file, attackers have a ready-made list to run through automated credential stuffing tools that test each login against banking portals, email providers, and social platforms. If a match succeeds, the consequences can chain quickly, an attacker who gets into someone's email can often reset passwords on their bank, shopping accounts, and social media, turning one leaked credential into a full-blown identity theft or financial fraud incident.

How the CryptogoL12 Stealer Log Was Built

Stealer logs like this one come from information-stealing malware that infects a device, usually through a malicious download, cracked software, or a phishing link, and quietly copies every saved password and login session from the victim's browser. That stolen data is packaged into a "log" and shared or sold on Telegram, and the ".26 7" in this file's name suggests it is one part of a larger, ongoing series of releases from the same campaign.

Check If You Are Affected

If your device was ever infected by the CryptogoL12 malware, your saved logins could be part of this file or a related one already in circulation.
