2,376 Verified U.S. Passwords Were Just Dumped on Telegram

HEROIC identified a stealer log file marketed as 2k HQ USA Valids on Telegram. The dump contains 2,376 credential records specifically targeting U.S.-based accounts. Each entry includes an email address, a plaintext password, and the URL where the login was captured. The label suggests these credentials have been tested and verified as working, making them especially valuable to attackers.

Verified Plaintext Passwords: The Worst-Case Scenario

Not only are the 2,376 passwords in this dump stored in plaintext, but the file title indicates they have been validated against live services. This means attackers do not need to guess which credentials still work — they have already been confirmed. Verified plaintext credentials represent the highest-risk category of stolen data because they combine immediate readability with confirmed access.

What Was Exposed

• Email Addresses — U.S.-based accounts confirmed active at the time of testing
• Plaintext Passwords — validated credentials ready for immediate unauthorized access
• URLs — the specific American services and platforms where credentials were captured

Credential Stuffing With Verified Data

Verified credential lists are prized in underground markets because they dramatically increase the success rate of credential stuffing attacks. Instead of testing millions of potentially stale entries, attackers work with a curated set of known-working logins. The 2,376 U.S. accounts in this dump will be tested against banking portals, healthcare systems, government services, and corporate platforms. With verified credentials, the success rate for these attacks jumps significantly.

How Infostealers Generate Verified Credential Lists

This data originated from infostealer malware running on compromised American devices. After the malware extracts saved passwords from browsers and transmits them to attacker servers, a secondary process begins — automated validation. Bots test each credential against the original website to confirm it still works. The resulting list of verified, working logins is then packaged and distributed on Telegram as a premium product for other cybercriminals.

Check If Your Credentials Were Exposed

HEROIC has incorporated this USA Valids credential dump into its breach database containing over 400 billion records. Use HEROIC's free breach scanner to find out if your email or password appears in this dataset. Given that these credentials were verified as working, taking immediate action is critical — change your password, enable two-factor authentication, and review recent login activity on your accounts.
