One Telegram Upload. One File. The Trident_Cloud Log Had 44,029 Stolen Records.

HEROIC analysts identified the Trident_Cloud stealer log breach in February 2026, when a Telegram user uploaded a log file containing 44,029 records. The exposed data included email addresses, plaintext passwords, and URLs, all extracted from devices infected with infostealer malware. The scale of this upload makes it one of the larger single stealer log dumps recorded in the DarkHive database for that period.

Why This Is Dangerous

With 44,029 plaintext credentials now circulating on Telegram, the window for account takeover is open right now. Attackers do not need any special skills to exploit this data. They can download the file and use it immediately to test logins across email providers, banks, online retailers, and social networks. The URL data reveals which sites victims were actively using, allowing criminals to prioritize the most valuable and sensitive accounts.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (sites visited and authenticated on infected devices)

Why This Matters

A breach of this size creates significant downstream risk. Credential stuffing tools can process tens of thousands of login pairs in minutes, testing them against popular platforms automatically. Successful hits lead to account takeovers, unauthorized purchases, fraudulent transfers, and identity theft. Many victims do not recieve any warning because the attack happens silently and the breached service itself was never hacked. The stolen credentials came directly from the user's device, making traditional breach notifications useless.

How Stealer Logs Work

Infostealer malware infects devices through phishing emails, fake software downloads, or malicious browser extensions. Once active, it quietly harvests everything stored in the browser, including saved passwords, session cookies, and a history of recently visited URLs. This data is packaged into a structured log file and transmitted back to the attacker. The Trident_Cloud file uploaded in February 2026 is a direct product of this process, likely representing infections across dozens or hundreds of individual devices.

Check If You Are Affected

Because stealer logs capture data at the device level, you could be in this breach even if none of your usual accounts reported a security incident. HEROIC's free dark web scanner checks your email address against the DarkHive database, which covers more than 400 billion exposed records across thousands of breaches and stealer log dumps. A scan takes only a few seconds and can definitaly tell you whether your credentials are circulating on the dark web right now.
