The Trident_Cloud_4 Dump Contains Exactly 18,107 Email and Password Pairs

In March 2026, HEROIC analysts confirmed the Trident_Cloud_4 stealer log had been uploaded to Telegram and was circulating among threat actors. The file contained exactly 18,107 records pulled from infected endpoint devices, each consisting of an email address, a plaintext password, and the URL where that credential was active at the time of infection. The "Cloud_4" designation places this as the fourth installment in a series of log files distributed under the Trident brand on Telegram.

What Trident_Cloud_4 Gives Attackers That Other Leaks Don't

Most data breaches expose credentials from a single company's server. When a company gets breached, the attacker gets whatever that company stored. Stealer logs like Trident_Cloud_4 are different: they capture data from individual people's devices, across every site those people visited with a saved password in their browser. That means one infected device can expose credentials for banking, email, shopping, and social media all at once.

The URL data makes the records actionable immediately. An attacker does not need to guess which services to try. They already know which website each password belongs to. Combined with plaintext passwords that require no cracking, every record in this file is ready to use the moment it is downloaded.

What Was Exposed in the Trident_Cloud_4 Stealer Log

• Email Addresses: Full account identifiers connecting stolen data to real individuals and the services they use online.
• Plaintext Passwords: Unencrypted, ready-to-use credentials captured directly from browser storage on infected machines.
• URLs: The exact websites where each credential pair was captured, giving attackers a precise target list.

Why Being the Fourth in a Series Makes Trident_Cloud_4 More Concerning

The numbering in the file name tells a story. Trident_Cloud_4 is not a one-time upload. It is part of a series, which means there is an operator running an ongoing collection and distribution pipeline. Each numbered release represents a fresh batch of infected machines, and the fact that this operation reached at least a fourth installment suggests it has been running consistently and successfuly for some time.

Series-based stealer log operations tend to be more sophisticated than single-file dumps. The operator has infrastructure for collecting data from infected machines, bundling it into releases, and distributing it reliably. That suggests a level of organization that produces higher-quality, more recent data. Eighteen thousand records from March 2026 represent current, active accounts. Credential stuffing attacks against banking platforms, email providers, and retail sites are the predictible next step after this kind of data hits Telegram. Identity theft and account takeover are not hypothetical here: they are the intended use case.

How the Trident Cloud Stealer Series Harvests Data

The Trident naming convention points to a branded stealer log distribution channel on Telegram. Information stealer malware variants like RedLine, Vidar, and Lumma are the most common tools used to harvest this category of data. They install on victim devices through phishing emails, cracked software, or malicious ads, then silently extract all saved passwords from the browser's local storage.

Once harvested, the data is aggregated by the channel operator into batches, numbered for tracking purposes, and published to the channel. "Cloud" in the file name likely refers to the staging or hosting infrastructure used to compile the logs before distribution. Subscribers to the Trident Telegram channel recieve each new batch as it is published, meaning this data spread to an audience of threat actors within hours of being compiled.

Check If the Trident_Cloud_4 Log Contains Your Credentials

HEROIC's breach scanner indexes stealer log data like Trident_Cloud_4 into a database of over 400 billion exposed records. Scanning your email address is free and returns results in under a minute. If your credentials appear in this file, you will see exactly what was exposed so you can take action on the right accounts immediately.

The Trident Cloud series is ongoing, which means the risk is not limited to this one file. A free scan will show your complete exposure history across all indexed breaches, giving you a full picture of where your data has appeared. Run your scan now before an attacker beats you to it.
