The KURTXT_ULP Live-Traffic Dump Exposed 80K US Accounts With Plaintext Passwords

HEROIC analysts identified the KURTXT_ULP Fresh 15 Million Lines from Live-Traffic stealer log, published on Telegram in July 2025, with 80,041 records verified from what the operator claimed was a 15 million line live-traffic dataset. The term "live-traffic" indicates credentials were captured in real time as users logged into websites on infected machines, making these among the most current and valid credentials in circulation. The dataset contained email addresses, plaintext passwords, and the URLs of the targeted services.

Why This Is Dangerous: Live-traffic harvesting means these credentials were captured at the moment of login, so they represent accounts the victims were actively using and almost certainly hadn't changed. With exact URL and plaintext password pairings, attackers have a direct map to every service each victim was accessing. This type of data is used for immediate account takeover without any additional processing or cracking.

What Was Exposed in the KURTXT_ULP Live-Traffic Stealer Log

• Email Addresses
• Plaintext Passwords
• URLs (live-traffic capture points where credentials were intercepted)

Why This Matters: Live-Traffic Logs Expose Accounts Across the United States and Beyond

Live-traffic stealer log data is distributed globally but the country metadata indicates a significant volume of United States-based accounts in this dataset. American users face risks across banking, retirement, healthcare portals, and corporate systems. Credential stuffing attacks using live-traffic data have a dramatically higher success rate than older breach data because the passwords have not yet expired or been changed. Victims can experience account takeover, identity theft, financial fraud, and unauthorized acces to employer systems all from a single credential exposure.

How Live-Traffic Stealer Logs Are Captured

Unlike database breaches that steal stored credentials, live-traffic stealer malware captures credentials as they are typed or autofilled by the victim. The malware hooks into browser processes and intercepts form submissions before they are encrypted, capturing the exact username, password, and destination URL in real time. This technique bypasses HTTPS encryption entirely because the data is captured before it ever reaches the network. The KURTXT operation used this technique at scale, claming to have collected 15 million lines of live-traffic data before distributing a sample via Telegram. Infected devices typically show no visible symptoms, making detection extremley difficult without dedicated malware scanning tools.

Check If You Are Affected by the KURTXT_ULP Live-Traffic Breach

If you have ever used a device that may have been compromised, your live login credentials could be in this dataset. Use HEROIC's free breach scanner to check your email against 400 billion+ compromised records from stealer logs, database breaches, and dark web sources. If your credentials appear, immediately change passwords for all affected accounts, revoke active sessions, enable two-factor authentication, and run a full malware removal scan on every device you own. The live-traffic nature of this data means your accounts may still be actively accessable to attackers right now.
