Check Your Email: The acninc.net Leak Exposed 7,372 Passwords

HEROIC analysts identified a stealer log connected to acninc.net that surfaced on Telegram on June 10, 2026. A Telegram user uploaded the file, which contained 7,372 records pulling together email addresses, plaintext passwords, and the URLs those credentials were used on, harvested directly from infected devices.

Why This Is Dangerous

Stealer logs are different from most breaches because the passwords inside them are not hashed or encrypted. They are stored in plaintext, exactly as they were typed. Anyone who gets a copy of this file can log into an affected account immediately, with no cracking or guessing involved. Worse, each password is paired with the URL where it was used, which hands an attacker a ready-made list of exactly which site to log into with which credential.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linked to each set of credentials

Why This Matters

If you reused a password from this list on any other account, that account is now at risk of credential stuffing, where attackers automatically test stolen logins across banking, email, and shopping sites. A compromised email account can also be used to reset passwords on other services, opening the door to account takeover, identity theft, and financial fraud that can take months to fully unwind.

How This Stealer Log Captured Your Passwords

Stealer logs like this one come from malware that quietly infects a device through a malicious download, a phishing link, or cracked software. Once installed, the malware scans the browser for saved passwords, autofill data, and active sessions, then quietly sends everything it finds back to the attacker. That stolen data is often packaged into a log file and shared or sold in Telegram channels, exactly like the one HEROIC analysts found here.

Check If You Are Affected

You do not have to guess whether your information was part of this leak. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including stealer logs like this one, and tells you in seconds if you need to change your passwords.
