Is Your Password in the John Doe Project Leak of 29,323 Logins?

On August 27th, 2025, a Telegram user uploaded a stealer log named "John Doe ProjectArhontCloud." HEROIC analysts confirmed the file contained 29,323 records pairing email addresses with plaintext passwords and the URLs each login was captured from, credentials taken directly from devices infected with information-stealing malware. If you have ever reused a password, this is worth checking.

Why This Is Dangerous

Every password in this file is stored in plain, readable text and matched to the exact site it unlocks. That means if your credentials are in this log, an attacker does not need to guess or crack anything, they can try logging in right now.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs (the login pages or API hosts tied to each credential)

Why This Matters

If you use the same password on more than one account, a leak like this can spread far beyond the original site. Attackers run plaintext email and password pairs through automated credential stuffing tools against banking, email, and shopping accounts, which is how one leaked password turns into account takeover, identity theft, or financial fraud on accounts you never thought were at risk.

How Stealer Log Breaches Work

Infostealer malware infects a device, often through a malicious download or cracked software, and silently copies every password, cookie, and autofill entry saved in your browser. That data is compiled into a log and distributed through Telegram channels and dark web forums, exactly the path this John Doe Project file took before HEROIC identified it.

Check If You Are Affected

You do not have to wonder. HEROIC's free breach scanner checks your email against more than 400 billion breached records, including this John Doe Project stealer log, and tells you in seconds if it is time to change a password.
