HEROIC Traced the cvv190_cloud Dump to 731 Compromised US Accounts

HEROIC analysts discovered the cvv190_cloud stealer log while monitoring Telegram channels known for distributing compromised credential files. The log, uploaded in January 2026 by an anonymous user, contained 731 records from infected devices in the United States. Each record included an email address, a plaintext password, and the URL of a site the victim was accessing at the time of infection. The data is the output of credential-harvesting malware that ran silently on victims' machines, collecting browser-saved login data and transmitting it to an attacker's server before anyone noticed the compromise.

Our Analysts Found the cvv190_cloud Dump on a Known Telegram Channel

HEROIC's threat intelligence team monitors hundreds of Telegram channels and dark web forums where stolen credential files are regularly shared. The cvv190_cloud upload appeared on one of these monitored channels in January 2026. The file was indexed, analyzed, and added to HEROIC's breach database so that affected users can identify their exposure. The 731 records in this log represent real people whose devices were compromised and whose login credentials are now in the hands of threat actors who downloaded the Telegram post.

What Was Exposed in the cvv190_cloud Stealer Log

• Email Addresses: The primary login identifier for most online services
• Plaintext Passwords: Immediately usable credentials requiring no decryption
• URLs: The specific websites the victim was logged into when their device was infected

Why This Matters: Credentials in the Wrong Hands

Plaintext passwords are the most dangerous form of leaked credential because they can be used immediately. Attackers who downloaded the cvv190_cloud log can begin testing each email-and-password pair against email platforms, banking sites, social networks, and corporate portals right away. Most people reuse passwords, which means one compromised set of credentials can open the door to multiple accounts across different services.

The URLs captured in this log remove the guesswork. Attackers do not need to try every possible service: the log tells them exactly which sites to target for each victim. This makes stealer log data significantly more effective for account takeover than generic credential dumps.

How Stealer Malware Infects Devices and Harvests Credentials

Stealer malware is distributed through phishing emails, malicious downloads, fake software cracks, and compromised browser extensions. When a user installs or runs the infected file, the malware activates silently in the background. It scans for passwords saved in Chrome, Firefox, Edge, and other browsers, harvests session cookies, and logs any credentials typed or autofilled during active browsing sessions. The collected data is compressed into a log file and transmitted to an attacker-controlled server, often within minutes of infection.

The attacker then sorts the logs by value, selling high-priority accounts on dark web markets and distributing lower-value bulk logs, like the cvv190_cloud upload, on public Telegram channels. Public distribution maximizes reach and helps threat actors build a following for future paid releases.

Check If Your Credentials Appear in This Breach

HEROIC actively monitors Telegram channels and dark web forums to collect and index stealer logs like cvv190_cloud. The breach database now contains more than 400 billion records, and you can search your email address for free to see if your credentials have been exposed in this breach or any other.

Visit HEROIC.com and run a free scan. If your email appears, change the affected password immediately, stop reusing it on other sites, and activate two-factor authentication wherever available.
