CB LOGS 500 Stealer Log: 4,433 U.S. Credentials Exposed via Telegram

In June 2022, a Telegram user operating under the name "Logs" uploaded a stealer log labeled CB LOGS 500 containing 4,433 records. The log exposed email addresses, plaintext passwords, and URLs harvested from infected U.S.-based devices. This batch is one of multiple uploads by the same "Logs" account, which distributed several credential datasets around this period, including CB LOGS 3, CB LOGS 5, CB LOGS 9, CB LOGS 11, CBLOGS, and PROTOTYPELOGS — indicating an organized stealer log distribution operation rather than a single incident.

Why This Is Dangerous

Plaintext passwords captured by stealer malware requrie no cracking to use. Every email and password pair in this dataset is immediately actionable for account takeover attempts. The URL data captured alongside credentials shows which web services the infected devices were logged into at the time of compromise, allowing attackers to prioritize targets with known high-value access — including corporate portals, API endpoints, and cloud management interfaces.

What Was Exposed

• Email addresses
• Plaintext passwords (immediate exploit risk — no cracking required)
• URLs and API host references from infected browser sessions

Why This Matters

This dataset has been in circulation since June 2022. Credentials from aged stealer logs remain dangerous because many victims are unaware thier data was ever captured and never changed the affected passwords. Attackers regularly revisit older datasets, running credential stuffing campaigns against current login forms. The same log file is often sold or shared across seperate underground markets, meaning multiple threat actors may be actively testing these credentials.

How Stealer Logs Work

Stealer malware infects devices through phishing emails, drive-by downloads, or trojanized software. Once installed, it silently extracts saved browser passwords, active session cookies, and the URLs of sites the user accessed. The data is bundled into a log file and transmitted to the attacker. These logs are then sold on Telegram channels and dark web forums. The "Logs" uploader appears to have been a recurring distributor of U.S.-focused stealer log batches, with thier uploads spanning multiple date ranges and naming conventions.

Check If You Are Affected

If you are a U.S.-based user whose device may have been compromised around or before June 2022, your credentials could be included in this dataset.
