Your Passwords May Be in the AYANKOUJI Stealer Leak: 23,867 Records

HEROIC analysts identified a stealer log dump known as "AYANKOUJI PRIVATE TG ArhontCorp," uploaded to a Telegram channel by an individual user on 16 June 2026. The file contained 23,867 records pulled directly from infected devices, including email addresses, plaintext passwords, and the URLs of the sites those credentials were used on.

Why This Stealer Log Is Dangerous

Unlike a typical company data breach, a stealer log comes straight from malware running on someone's own computer. That means the passwords in this file are not hashed or scrambled in any way, they are stored in plain, readable text, exactly as the victim typed them.

Because each password is paired with the exact website URL it was used on, an attacker doesn't have to guess where to try the login. They can go straight to the bank, email provider, or shopping account and log in like the real owner. This is one of the more immediatly usable formats of stolen data circulating on the dark web.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the accounts the credentials belong to

Why This Matters for Everyday Accounts

Records like these are the raw material of credential stuffing attacks, where automated tools try the same email and password pair across hundreds of other websites. If you reuse passwords, and many people do, one leaked login can quickly turn into several hijacked accounts.

From there, the path to account takeover, identity theft, and financial fraud is short. A criminal who gets into an email inbox can reset passwords on banking, retail, and social media accounts, often before the original owner even notices anything is wrong.

How Stealer Logs Work

Stealer malware infects a device quietly, often through a cracked software download, a fake browser update, or a malicious email attachment. Once installed, it scans the browser's saved logins, autofill data, and cookies, then quietly ships everything back to the attacker.

The attacker packages up thousands of these harvested credentials into a single file, sometimes called a "log," and sells or shares it on Telegram channels and dark web forums. This particular log appears to have been uploaded free of charge by a single Telegram user, which means it may already be circulating widely among lower-tier criminals who couldn't otherwise affford access to fresher data.
