Our Analysts Found the Reimann Cloud 07-25 Dump on Telegram

HEROIC analysts monitoring underground channels in April 2023 came across the Reimann Cloud 07-25 stealer log being distributed in a private Telegram group. Inside the file: 1,161 sets of stolen credentials -- email addresses, plaintext passwords, and the URLs of every online service each victim had been logged into. This is how most stealer log breaches are distributed: quietly, quickly, and among people who know exactly how to use the data. By the time the log was identified and cataloged, it had already been accessable to criminals for an unknown period.

Why This Is Dangerous

Telegram has become one of the primary distribution channels for stolen credential data. Private groups operate in plain sight, sharing stealer logs, combolists, and hacking tools among thousands of members. The Reimann Cloud 07-25 stealer log exposed plaintext passwords -- no decryption, no cracking, no delay. The moment this file was shared in a Telegram channel, every email address and password in it was available to everyone in that group. Credential-stuffing bots can process thousands of login attempts per hour, meaning victims' accounts may have been compromised within hours of the log's release.

What Was Exposed

• Email Addresses -- used as account identifiers across virtually every online platform
• Plaintext Passwords -- unencrypted and ready to use with no technical skills required
• URLs -- identifying exactly which services and sites each victim had active sessions on

Why This Matters

When our analysts find a stealer log circulating in Telegram, it's already too late for the people in it -- the data has been shared and the window for prevention has closed. That's why early detection matters. The Reimann Cloud 07-25 log contains 1,161 credential sets that can be used for account takeover, phishing, and credential stuffing. For anyone whose email appears in this breach, the risk is active and real: every account using that password combination may be vulnerble right now. Knowing early gives you the chance to respond before attackers strike.

How Stealer Log Breaches Work

Stealer logs get their name from the infostealer malware that creates them. Software like RedLine Stealer, Raccoon, or Vidar infiltrates a victim's computer -- usually through malicious downloads, phishing links, or drive-by infections. Once installed, the malware extracts every password saved in the browser, along with the URL and username for each one. Active session cookies are captured too, potentially allowing account access even without a password. All of this data is assembled into a structured log file and sent to the attacker's server. These logs then get bundled, traded, and distributed -- frequently via Telegram channels that operate like underground markets for stolen data.

Check If You Are Affected

HEROIC's free breach scanner searches over 400 billion exposed records to check whether your email appeared in the Reimann Cloud 07-25 stealer log or any other known breach. Enter your email address for instant results. If your credentials are in this log, change affected passwords immediately and enable two-factor authentification on every account that supports it -- especially email, banking, and cloud storage.
