Telegram Stealer Log “1230” Exposes 226,833 US Credentials

HEROIC analysts identified the 1230 stealer log circulating on Telegram in April 2025. This release exposed 226,833 records containing email addresses, plaintext passwords, and URLs harvested from compromised devices. The volume of this single release makes it a significant threat to individuals whose credentials were captured by the underlying infostealer malware.

Why This Is Dangerous

Stealer logs capture live credentials at the moment of infection. Because plaintext passwords are recorded directly from the victim's browser or device, there is no hashing barrier to protect them. Attackers can immediately use these credentials to access email inboxes, banking portals, work accounts, and any other service where the same password was reused. The inclusion of URLs means attackers know exactly which sites each credential pair belongs to, enabling rapid and targeted account takeover.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs (specific sites the victim was logged into)

Why This Matters

Credentials from stealer logs feed directly into criminal ecosystems. Threat actors use them for credential stuffing attacks against banks, email providers, and corporate systems. They sell network access on dark web marketplaces, drain financial accounts, and commit identity theft at scale. With over 226,000 records in this release alone, the potential for widespread harm is substantial. Because passwords are in plaintext, no cracking is required and exploitation can begin immediately.

How Stealer Log Breaches Work

Stealer logs are produced by information-stealing malware installed on victims' computers, typically through phishing emails, malicious downloads, or trojanized software installers. Once running, the malware silently harvests saved browser credentials, session cookies, and form autofill data. It records the username, password, and URL for each site, then packages everything into a log file uploaded to a command-and-control server or shared on Telegram channels. Victims are rarely aware they have been infected. The data is then organized, sold, or distributed freely to maximize reach among criminal actors.
