Your Login Credentials May Already Be Stolen. The FreeOLDCloud Stealer Log Exposed 11,590 Records.

In September 2023, HEROIC analysts detected a stealer log file being distributed via Telegram under the name FreeOLDCloud. The file contained 11,590 records harvested from compromised devices, including email addresses, plaintext passwords, and the URLs where those credentials were stolen. This type of leak does not come from a single hacked company. It comes from malware running quietly on individual computers, collecting every password saved in the browser.

Why This Stealer Log Is Particularly Dangerous

What makes this dataset so damaging is the combination of data types. Email addresses on their own are annoying. Plaintext passwords on their own are bad. But together, alongside the specific URLs where the credentials were captured, attackers have everything they need to log into real accounts immediately.

There is no cracking required, no guessing, no brute force. The passwords in this file are already in clear text. An attacker can recieve this file, open it like a spreadsheet, and start trying logins within minutes of obtaining it.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (login pages where credentials were captured)

Why This Matters Beyond the Breach Itself

Stealer log data circulates on dark web forums and Telegram channels for months or even years after the initial leak. A file uploaded in 2023 can still be actively used by criminals in 2025 and beyond. Each time it gets shared to a new channel, a new set of attackers gains access to the same credentials.

The most common outcomes include credential stuffing attacks across email, banking, and social media platforms. Victims often notice something is wrong only after their account has been accessed, their password changed, or a fraudulent purchase has occured. By then, the damage is already done.

How Stealer Logs Are Created and Distributed

Stealer logs are generated by a category of malware called infostealers. These programs are usually delivered through phishing emails, pirated software downloads, or malicious browser extensions. Once installed on a device, they scan the browser's saved passwords, session tokens, and browsing history, packaging everything into a tidy log file that gets sent back to the attacker.

The attacker then distributes these files through underground marketplaces or, increasingly, through Telegram channels dedicated to credential trading. The FreeOLDCloud file followed this exact pattern, moving from an infected device to a public Telegram channel where it became available to anyone who knew where to look.

Check If Your Data Was Included

HEROIC maintains a searchable database of over 400 billion breach records, including stealer log data like the FreeOLDCloud file. Our free breach scanner lets you enter your email address and see whether your credentials have appeared in any known leak.

If your data shows up, you will know exactly what was exposed and can take steps to secure your accounts before an attacker does. It is definately worth the 30 seconds it takes to check.
