The TIZIX FREE Stealer Log Exposed 2,188 US-Targeted Accounts on Telegram

In June 2023, a Telegram user uploaded a stealer log file labeled TIZIX FREE, exposing 2,188 records containing email addresses, plaintext passwords, and URLs harvested from infected devices. The breach is indexed by HEROIC DarkHive as targeting US-based accounts, consistent with the English-language platforms and services captured in the endpoint data. HEROIC analysts identifed this file while monitoring Telegram channels where infostealer operators distribute credential packages to criminal buyers. This dataset was distributed as a free share, making it accessible to any threat actor in the relevant channels without purchase or negotiation. The 2,188 people in this breech had no idea their credentials were posted online and have likely never recieved any notification that their data is in criminal hands.

Why This Is Dangerous

The size of a breach does not determine its danger. Over two thousand plaintext passwords paired with email addresses and service URLs is more than enough for a focused credential stuffing campaign targeting US-based services. Attackers do not need millions of records to cause serious harm. Because the TIZIX FREE dataset was distributed as a free share on Telegram, it reached the widest possible audience with no paywall limiting who could download it. Any affected accounts that have not had passwords changed since June 2023 remain actively vulnerable to automated login attacks today.

What Was Exposed

• Email Addresses: Victim email addresses linked to US-based accounts, used as usernames and recovery contacts across dozens of online services
• Plaintext Passwords: Fully readable, unencrypted passwords requiring no cracking, ready for immediate use in credential stuffing attacks
• URLs and Endpoints: The specific US-based websites and services each victim was actively using when their device was compromised, giving attackers a direct target list

Why This Matters

Stealer log breaches targeting US accounts are particularly valuable to criminal networks because US-based services typically have higher account balances, more stored payment methods, and more connected financial integrations. A single compromised US email account can cascade into bank account access, credit card fraud, and identity theft through password reset chains. Because the TIZIX FREE file has been circulating since 2023, automated credential stuffing tools have had years to test these logins against email providers, banking platforms, and social media services continuosly. Affected users who have not changed their passwords remain exposed to the same risk today as they were when the breach first appeared.

How Stealer Logs Work

Stealer logs are produced by infostealer malware that infects computers through phishing messages, trojanized software, or malicious browser extensions. Once active, the malware silently harvests saved browser passwords, captures URLs from active sessions, and records any credentials entered during the infection window. The collected data is packaged into a structured log and sent back to the attacker's infrastructure, then uploaded to Telegram for distribution. The TIZIX FREE file was shared freely, meaning anyone in the relevant Telegram channels could download it immediatley and begin testing the credentials against US banking portals, e-commerce platforms, and email providers. Victims recieve no alert at any point in this process.
