CB Logs 3 Stealer Log Exposes 21,797 U.S. Credentials

HEROIC's DarkHive system discovered the CB Logs 3 breach, exposing 21,797 records on May 13, 2022. This stealer log dataset contains email addresses, plaintext passwords, and URLs harvested from infected devices across the United States by infostealer malware distributed through Telegram channels.

Why This Is Dangerous

CB Logs 3 is one of the larger stealer log releases in the CB series, containing over 21,000 credentials from U.S. devices. Datasets of this scale enable mass automated credential stuffing campaigns that target thousands of online services simultaneously. The plaintext nature of the passwords means attackers require no additional processing to begin exploiting accounts immediately after obtaining the dataset.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs and API host references from infected browser sessions
• Geographic data indicating United States origin

Why This Matters

At 21,797 records, CB Logs 3 provides attackers with significant reach for account takeover operations. Each credential pair represents a real user account that was actively in use at the time of infection. Password reuse means a single exposed credential can compromise banking, email, cloud storage, and corporate access simultaneously. Session cookies bundled in stealer logs further allow attackers to bypass two-factor authentication, ensuring compromised access persists even after password resets.

How Stealer Log Breaches Work

Infostealer malware infects devices through phishing campaigns, malicious software downloads, and compromised browser extensions. Once installed, the malware silently harvests all browser-stored credentials, session tokens, and browsing history, transmitting the data to attacker-controlled Telegram channels. Operators like CB compile these logs into numbered series for distribution to criminal subscribers. HEROIC's DarkHive system continuously monitors these channels to detect and catalog new breach datasets the moment they appear.
