If You Reuse Passwords, the Piece Private 175 Leak Should Worry You

What HEROIC Analysts Found in the Piece Private 175 Leak

On September 8, 2025, HEROIC analysts identified a combolist titled "Piece Private 175" after it was uploaded to a Telegram channel by an individual user. The file contains 956 records pairing email addresses with plaintext passwords, along with the URLs of the login pages those credentials belong to. The affected accounts are tied primarily to the United States.

Why This Is Dangerous

If you reuse the same password across more than one account, a leak like this one should worry you specifically. The passwords in this file are stored in plaintext, so anyone who downloads it can read and try them instantly, and if your credentials are inside, an attacker does not need to guess or crack anything to get in.

What Was Exposed in the Piece Private 175 Combolist

• Email addresses
• Plaintext passwords
• URLs identifying the associated login pages

Why This Matters

Combolists like this one exist for one purpose, credential stuffing. Attackers run each of the 956 email and password pairs against banking sites, email providers, and online retailers to see which ones still work. Anyone who reused their password elsewhere is at risk of account takeover, unauthorized purchases, and identity theft, since a single working login can unlock several unrelated accounts at once.

How This Combolist Was Likely Built

Combolists like Piece Private 175 are typically assembled by pulling email and password pairs from older breaches, phishing pages, or malware infected devices, then bundling them into a numbered file for easy tracking and resale. Once uploaded to a Telegram channel, the file can be downloaded and used by anyone within minutes, no technical skill required.

Check If You Are Affected

If you have ever reused a password, it is worth checking your exposure now. HEROIC's free breach scanner checks your information against a database of more than 400 billion leaked records, so you can quickly see whether your credentials appear in this leak or another one and update anything you have reused.
