One Telegram Upload. 835 Records. The PIECE PRIVATE 18 Leak.

What HEROIC Analysts Found

HEROIC analysts identified a smaller combolist file dated June 28, 2025, uploaded to a private Telegram channel under the name "PIECE PRIVATE 18." The file held 835 records pairing email addresses with plaintext passwords and the website URLs those credentials were tied to. Unlike large-scale database dumps, this file represents a compact, curated batch that a single uploader assembled and shared for other Telegram users to grab.

Why This Is Dangerous

Small file size does not mean small risk. Because each password sits in plaintext next to the exact URL it belongs to, anyone who downloads PIECE PRIVATE 18 can immediately attempt to log into those accounts without doing any extra work to crack or decode the data. A file this size can be tested against target sites in minutes using free, widely available tools.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated website URLs

Why This Matters

Even a list of 835 accounts is enough to fuel credential stuffing, where attackers automatically try each stolen email and password pair across many other websites at once. If any of these 835 people reused their password on a bank, email account, or shopping site, that account can be taken over. Once inside, an attacker can reset other passwords, make unauthorized purchases, or use the stolen identity to open new accounts.

How Combolist Leaks Work

A combolist is a simple text file listing stolen usernames or emails alongside their passwords, usually formatted as "email:password" per line. These files are frequently pulled together from older breaches, malware-infected devices, or previous leaks rather than one single hack, then repackaged and shared under a new name, like PIECE PRIVATE 18. Their small size makes them easy to move quickly through private Telegram groups, where they change hands with little scrutiny.
