1starnet.com Breach: 2,372 Plaintext Passwords Exposed Online

In June 2026, HEROIC analysts identified a combolist tied to 1starnet.com circulating on Telegram. The file, uploaded by a Telegram user on June 10, 2026, contains 2,372 records pairing email addresses with plaintext passwords, along with associated URLs pointing to the sites those credentials unlock.

Why the 1starnet.com Leak Is Dangerous

The passwords in this file were stored and shared in plaintext, meaning there is no encryption or hashing standing between an attacker and a working login. Anyone who downloads this combolist can use the email and password pairs immediately, no cracking or decryption required. Because the leak also includes URLs, an attacker knows exactly which site each credential pair is meant to unlock, cutting out the guesswork and making automated login attempts far more efficient.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linked to the accounts

Why This Matters

Most people reuse the same password, or a close variation of it, across several accounts. When a plaintext password leaks alongside an email address, attackers plug that pair into automated tools and test it against banking sites, email providers, and social media platforms in a technique known as credential stuffing. A single reused password can cascade into a full account takeover, opening the door to identity theft and financial fraud on accounts that were never part of the original breach.

How a Combolist Leak Works

A combolist is exactly what it sounds like: a compiled list combining usernames or emails with their matching passwords, gathered from multiple smaller breaches, malware infections, or phishing campaigns and merged into one file. Unlike a raw database dump, a combolist is built specifically to be plugged into automated login tools, which is why cybercriminals trade them so heavily on Telegram channels and dark web forums. Once shared, a combolist can be downloaded and reused by dozens of different threat actors, each running their own credential stuffing attempts against different targets.

Check If You Are Affected

If you have ever used an email address tied to 1starnet.com, or reused a password across multiple accounts, it is worth finding out whether your information appears in this leak. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including combolists like this one, so you can see your exposure and take action before an attacker does.
