1,008 Plaintext Passwords Leaked in the PIECE PRIVATE 53 Telegram Dump

HEROIC analysts identified a combolist file circulating on Telegram in July 2025, labeled PIECE PRIVATE 53. The file contained 1,008 records pairing email addresses with plaintext passwords, along with the URLs of the sites those credentials were originally used on.

Why the PIECE PRIVATE 53 Leak Is Dangerous

Because the passwords in this file are stored in plaintext, anyone who downloads it can read the exact password tied to each email address with no extra work. Paired with the leaked URLs, an attacker can immediately see which website each login was used for, making it easy to try that same email and password combination on the original site or on other popular services.

What Was Exposed in PIECE PRIVATE 53

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

Why This Matters for the People Affected

Combolists like this one are built specifically for automated attacks. Criminals load files like PIECE PRIVATE 53 into credential stuffing tools that test each email and password pair against banking, email, and shopping sites in bulk. If any of the 1,008 people in this file reused their password elsewhere, those other accounts are now at risk of takeover, financial fraud, or identity theft.

How Combolist Leaks Like This One Work

A combolist is a plain text file that pairs usernames or emails with passwords, usually gathered from older breaches, phishing pages, or malware infections and repackaged for resale or free distribution. Telegram has become a common distribution point for these files because it lets uploaders reach buyers quickly with little oversight. Files like PIECE PRIVATE 53 are often small compared to major breaches, but the credentials inside are just as usable by an attacker running automated login attempts.
