553 Email and Password Pairs From PIECE PRIVATE 13 Leaked Online

In late June 2025, HEROIC analysts identified a combolist labeled PIECE PRIVATE 13 that had been uploaded to Telegram by an unnamed user. The file contained 553 records pairing email addresses with plaintext passwords, along with associated URLs showing which sites the credentials were used on. The data was verified as of June 26, 2025.

Why a Small Leak Still Puts People at Risk

A list of 553 accounts might sound minor compared to headline-grabbing breaches, but the danger to each person affected is identical. Because the passwords were stored and leaked in plaintext, anyone who finds this file can log in immediately without cracking or guessing anything. If the same email and password combination was reused anywhere else, an attacker already has the key.

What Was Exposed in PIECE PRIVATE 13

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

Why This Matters

Combolists like this one are traded specifically because they are ready to use. Criminals feed the email and password pairs into automated tools that try the same login on banking sites, email providers, and shopping accounts, a technique known as credential stuffing. When a match works, it can lead to account takeover, identity theft, or direct financial fraud, all without the victim ever clicking a phishing link.

How a Combolist Like This Gets Built

A combolist is simply a compiled file of username or email and password pairs, often pulled together from older breaches, stealer malware logs, or credential-testing sessions and repackaged for resale or free distribution. Telegram has become a common marketplace for this kind of file because it lets sellers reach buyers quickly with little oversight. The inclusion of URLs alongside each credential pair, as seen in PIECE PRIVATE 13, tells a buyer exactly which site to target first.

Check If You Are Affected

Even a smaller leak like PIECE PRIVATE 13 is worth checking, since reused passwords are the single biggest reason small combolists turn into bigger problems for victims. HEROIC's free breach scanner searches a database of more than 400 billion leaked records to tell you in seconds whether your email address shows up in this leak or any other, so you can change exposed passwords before someone else uses them.
