CryptogoL12 Stealer Log: 544 Plaintext Passwords and Emails Exposed

HEROIC analysts identified a stealer log uploaded by a Telegram user on 24 July 2026, containing 544 exposed records tied to compromised devices. The log includes email addresses, plaintext passwords, and the URLs of the websites those credentials were used on, giving anyone who obtains the file a ready-made list of working login combinations for real accounts.

Why This Is Dangerous

Because the passwords in this log were stored and leaked in plaintext, no cracking or decryption is required. An attacker can open the file and immediately see usernames, passwords, and the exact site each pair unlocks. Paired with the URLs, this turns a raw data dump into a ready-made attack list rather than a puzzle to solve.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the associated login pages

Why This Matters

Even a small batch of 544 records can cause outsized damage. Attackers routinely feed logs like this into automated credential stuffing tools that test the same email and password combination across banking, email, and shopping sites. If you have reused a password from one of the exposed accounts anywhere else, every one of those accounts is now at risk of takeover, financial fraud, or identity theft.

How Stealer Logs Work

Stealer logs come from infostealer malware, malicious software that infects a device (often through a fake download, cracked software, or phishing link) and quietly harvests everything saved in the browser: stored passwords, autofill data, session cookies, and the URLs of the sites they belong to. The malware packages this into a log and sends it back to whoever controls it. From there, logs like this one are frequently shared or sold in Telegram channels, exactly as this batch was, before circulating further across dark web marketplaces.

Check If You Are Affected

Reused passwords are the single biggest reason one small leak turns into many compromised accounts. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including logs like this one, so you can find out in seconds whether your information has been exposed and take action before an attacker does.
