The ‘PIECE PRIVATE 41’ Combolist Exposed 999 US Passwords

999 US Accounts Exposed in the "PIECE PRIVATE 41" Combolist

On July 4, 2025, HEROIC analysts found a combolist labeled "PIECE PRIVATE 41" circulating in a private Telegram channel, containing credentials tied to United States accounts. The file held 999 records of email addresses paired with plaintext passwords, along with URLs identifying the site each credential was captured from.

Why This Combolist Is Dangerous

Because the passwords in this file are stored in plaintext, anyone who gets hold of the list can use the credentials right away, with no cracking needed. Paired with the included URLs, an attacker can quickly identify which US-based sites each login belongs to and attempt to access those accounts directly, or try the same password on other services.

What Was Exposed in the "PIECE PRIVATE 41" Leak

• Email addresses
• Plaintext passwords
• URLs tied to each credential pair

Why This Matters for the US Accounts Involved

A file this size is a manageable target for automated credential stuffing, where bots systematically test every email and password combination against popular US websites and services. If your credentials appear here and you have reused the password elsewhere, you risk account takeover, identity theft, and financial fraud tied to any accounts sharing that password.

How Combolists Like This One Are Built

Combolists are assembled by combining credentials from smaller breaches, phishing campaigns, and malware infections into a single file, then labeled and sold or shared in private Telegram channels. Even a file with fewer than a thousand records, like this one, can be used effectively because automated tools can test every entry against dozens of websites within minutes.
