The ArhontCorp Traffic Logs Gave Hackers Everything to Hijack 1,401 Accounts

In August 2026, HEROIC analysts tracked a stealer log file labeled Traffic Logs TG ArhontCorp.part5 being shared by a user on Telegram. The file contained 1,401 records pulled from infected devices, including email addresses, plaintext passwords, and the URLs of the accounts those credentials unlock. Because the passwords are stored in plaintext, no cracking is required. Anyone with the file can log in immediately.

Why This Is Dangerous

A traffic log like this one is built from real browsing activity on infected machines, which means the credentials inside it are current and working, not old passwords pulled from a years-old breach. Each entry pairs a login with the exact website it belongs to, so an attacker doesn't need to guess where to use it. They can go straight to the account and log in as if they were the real owner.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the associated login pages

Why This Matters

Even a smaller record set like this one carries real risk for the people in it. Attackers can use these credentials to take over email and other online accounts, then use that access to reset passwords elsewhere, impersonate the victim, or attempt credential stuffing against banking and shopping sites using the same email and password. Anyone who reused a password across more than one account is at the greatest risk.

How ArhontCorp's Traffic Logs Were Collected

Traffic logs are generated by infostealer malware that infects a device and quietly copies saved browser passwords, autofill data, and session information as the victim goes about normal browsing. The malware bundles everything it captures into a log file, which is then sold or shared in bulk on Telegram channels and dark web forums, often split into numbered parts, as this one was. Because the data comes directly from an active, infected device, it tends to be far more current and reliable to attackers than credentials pulled from an old, publicly known breach.

Check If You Are Affected
