The YANKOUJI Free Logs Quietly Surfaced on the Dark Web

HEROIC analysts spotted a stealer log named YANKOUJI FREE LOGS uploaded to Telegram on 12 August 2026. The file is small compared to many dumps HEROIC tracks, containing 1,399 records, but each one includes an email address, a plaintext password, and the URL of the account it unlocks.

Why the YANKOUJI Free Logs Are Dangerous

Size is not the whole story with a stealer log. This data was pulled directly from infected devices, meaning each of the 1,399 entries pairs a real, working login with the exact site it belongs to. An attacker does not need to crack or guess anything, they can simply try the credentials and see if they still work.

What Was Exposed in YANKOUJI Free Logs

• Email addresses collected from infected devices
• Plaintext passwords with no encryption applied
• URLs identifying which websites and accounts each login belongs to

Why This Matters Even at a Small Scale

A smaller record count does not mean smaller risk for the people involved. If any of these 1,399 accounts reused a password on another site, attackers can use credential stuffing to try that same combination against banking, email, or shopping accounts, opening the door to account takeover, financial fraud, or identity theft.

How a Stealer Log Like This Gets Made

Info-stealer malware infects a device, often through a fake download or malicious attachment, then quietly copies saved browser passwords, autofill data, and active sessions. The results are packaged into a log file and shared through Telegram channels, which is where HEROIC's analysts found YANKOUJI FREE LOGS circulating on 12 August 2026. Being labeled free often means it is distributed widely at no cost, which can put the data in front of more potential attackers.
