Search Your Email: The Trident_Cloud_3 Leak Exposed 8,998 Records

What HEROIC Analysts Found

On August 3, 2026, HEROIC analysts identified a stealer log labeled Trident_Cloud_3 circulating after being uploaded by a Telegram user. The file contained 8,998 records, each pairing an email address with a plaintext password and the URL of the site or app the credentials belonged to.

Why the Trident_Cloud_3 Leak Is Dangerous

Because the passwords in this log were captured in plaintext directly from infected devices, they are ready to use the moment someone downloads the file. There is no need to crack or decrypt anything. An attacker can pair each email address with its matching password and URL, then log straight into the account it was stolen from, or try the same combination on other popular sites where the same password might have been reused.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linking each credential pair to the website or service it was used on

Why This Matters

Stealer logs like this one feed directly into credential stuffing attacks, where automated tools test stolen username and password pairs against banking sites, email providers, and social media platforms. If any of the 8,998 people in this file reused a password across accounts, one exposed login can turn into several. It is a common path to account takeover, financial fraud, and identity theft.

How Stealer Logs Work

A stealer log is the output of infostealer malware, a type of program that quietly infects a device and copies saved browser passwords, autofill data, and login sessions before sending everything back to whoever controls the malware. The Trident_Cloud_3 file appears to be exactly this kind of harvest, packaged up and shared on Telegram where anyone can download it.

Check If You Are Affected

You do not have to guess whether your information is sitting in a file like this one. HEROIC's free breach scanner checks your email address against a database of more than 400 billion leaked records, including stealer logs like Trident_Cloud_3, and tells you in seconds if you need to change a password.
