The TG InvictusCloud Breach Put 37,137 Stolen Login Pairs Online via Telegram

On August 12, 2025, security analysts identified a stealer log file that had been posted to a public Telegram channel. The upload was traced to a source identified as TG InvictusCloud. The file held 37,137 records, each one containing an email address, a plaintext password, and a URL connected to an API host or website. This data was not stolen from a single company. It was collected by malware running on infected devices, silently gathering login credentials from real people without them ever knowing. Once uploaded to Telegram, it became instantly available to anyone in those channels looking to exploit it.

Why This Is Dangerous

Attackers do not need to do any heavy lifting with a log like this. The passwords are already in plain text, ready to copy and paste. Criminals load the full list of email and password pairs into automated tools that test them against Gmail, Outlook, banking sites, PayPal, Amazon, and anywhere else people log in. The included URLs narrow it down even further, pointing directly to which services each persons credentials belong to. This makes targeting faster and more efficient. Anyone whose data is in this log could have their accounts accessed within hours of the file going live on Telegram.

What Was Exposed in the TG InvictusCloud Breach

• Email addresses
• Plaintext passwords (no hashing, no encrption)
• URLs and API host addresses associated with the stolen logins

Why This Matters

Credential stuffing is one of the most common ways accounts get taken over today. Attackers take stolen login pairs like those in this log and try them everywhere. Because so many people use the same password on multiple sites, a single match can open the door to email accounts, bank accounts, shopping accounts, and more. Once inside an email account, an attacker can trigger password resets on everything else. This creates a chain reaction that can result in identity theft, financial fraud, and personal data being exposed or sold. Breaches like this one feed that cycle directly.

How Stealer Logs Work

Infostealer malware lands on a device through a phishing email, a fake software installer, or a drive-by download from a compromised website. Once installed, it runs quietly in the background and collects everything saved in browsers and applications, including passwords, cookies, and login tokens. It bundles all of this into a log file and sends it back to the atacker who deployed it. These logs are then sold, traded, or given away on Telegram channels and dark web marketplaces, where other criminals use the credentials to fuel account takeover operations.
