Dark Web Intel: 3,217 Credentials From the ‘PIECE PRIVATE 163’ Leak

Dark Web Intel: 3,217 Credentials Found in the "PIECE PRIVATE 163" Leak

On September 4, 2025, HEROIC analysts tracked a combolist labeled "PIECE PRIVATE 163" circulating in a private Telegram channel. The file contained 3,217 records pairing email addresses with plaintext passwords, along with URLs identifying the site each credential was captured from.

Why This Combolist Is Dangerous

Because the passwords are stored in plaintext, anyone with access to this file can attempt logins right away, with no cracking involved. The URLs paired with each credential make it simple for an attacker to identify exactly which site to target, and a list of this size is large enough to be useful for automated, large-scale login attempts.

What Was Exposed in the "PIECE PRIVATE 163" Leak

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

Why This Matters for the Accounts Involved

A file of over 3,000 credentials is a solid working list for credential stuffing, where automated bots test every entry against major websites in a short amount of time. If your email and password appear here, and especially if you reused that password elsewhere, you risk account takeover, identity theft, and financial fraud tied to any account sharing that login.

How Dark Web Combolists Like This One Circulate

Combolists such as this are assembled from smaller breaches, phishing kits, and malware-stolen credentials, then bundled together and labeled for distribution. Once compiled, they are traded and sold in private Telegram channels and dark web marketplaces, where buyers use automated tools to run bulk login attempts against banking, retail, email, and social media platforms.
