Our Analysts Found the CRYPTON_TXT Dump Circulating in Private Telegram Channels

In November 2025, HEROIC analysts monitoring underground Telegram channels discovered a stealer log archive being circulated under the name CRYPTON_TXT 26.11. The file contained 1,843,730 records harvested from compromised devices, each including an email address, a plaintext password, and the URL of the service where those credentials were in active use. The dump was shared in private channels frequented by threat actors seeking ready-to-use stolen credentials.

Why Finding the CRYPTON_TXT Dump in Private Channels Matters

When a stealer log surfaces in private Telegram groups rather than public forums, it often signals that the data is being used before it becomes widely known. Victims in this archive may have had their accounts targeted before any public reporting on the leak. With 1,843,730 plaintext credential sets tied directly to the websites where they were used, the CRYPTON_TXT dump represents a significant operational resource for credential stuffing attacks, account hijacking campaigns, and targeted phishing. The speed at which these files move through underground networks makes early detection critical.

What the CRYPTON_TXT 26.11 Stealer Log Exposed

Every record in the CRYPTON_TXT archive contained:

• Email addresses (used as account usernames on the compromised services)
• Plaintext passwords (captured live from infected devices, no encryption)
• URLs (the exact websites where each credential was used)

The combination of all three data types in a single record makes each entry immediately usable by any criminal who downloads the file. There is no additional processing required.

Why the CRYPTON_TXT Scale Amplifies the Risk of Account Takeover

Nearly two million records in a single stealer log archive represents a large pool of potential victims for automated attacks. Credential stuffing tools can test these email-password combinations against banking portals, email services, and streaming platforms in a matter of hours. Because many people reuse passwords across multiple sites, a single stolen credential from one captured URL can open doors to entirely seperate services the malware never directly targeted. The downstream consequences include drained financial accounts, hijacked email inboxes used to reset other passwords, identity theft, and unauthorized access to workplace systems if corporate credentials were among those captured.

How the CRYPTON_TXT Stealer Log Was Created

Stealer log files like CRYPTON_TXT originate with malware silently running on victims' computers. The infection typically enters a system through a malicious download, a compromised software installer, or a fake browser extension. Once active, the infostealer scans browser password stores, reads autofill data, and monitors active sessions. For each credential it finds, the malware records the associated URL, creating the URL-login-password format that defines ULP archives. All of this information is packaged into a compressed log file and transmitted back to the attacker. The resulting archive is then sold or distributed through Telegram channels, where it circulates among multiple threat actors simultaniously. The CRYPTON_TXT 26.11 file represents the output of that process applied to 1,843,730 real victims.
