PIECE PRIVATE 12 Passwords Leaked in 2025 Are Only Surfacing Now

The combolist known as PIECE PRIVATE 12 is dated back to June 26, 2025, but it only came onto HEROIC analysts' radar recently, when it was found circulating on Telegram. The file contains 868 records pairing email addresses with plaintext passwords, along with URLs identifying the sites those logins belonged to.

Why Old Data Can Still Be a Fresh Threat

A gap between when a file was first created and when it starts circulating widely is common with combolists. The credentials do not expire on their own, so a list assembled over a year ago can still work perfectly today if the people in it never changed their passwords. Because these passwords are stored in plaintext, anyone who picks up the file can start testing logins right away.

What Was Exposed in PIECE PRIVATE 12

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

Why This Matters

Whether a combolist is brand new or has been sitting around since 2025, the danger to the people in it is the same the moment it gets tested. Attackers run these email and password pairs through automated tools against banking sites, email providers, and shopping accounts, a technique called credential stuffing. Anyone who reused their PIECE PRIVATE 12 password elsewhere faces a real risk of account takeover, identity theft, or financial fraud.

How a Combolist Like This Resurfaces

Credential files often pass through multiple hands before reaching a wider audience. A list compiled in one Telegram channel can sit quietly for months before being reshared, repackaged, or sold in a new channel, which is likely what happened here. The URLs bundled with each entry make the file easy to reuse no matter how much time has passed since it was first built.

Check If You Are Affected

Because this data has been circulating since 2025, anyone in this file has had a long window during which their credentials could have been tested. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including this one, so you can find out now and change any exposed passwords before they are used against you.
