Poland Valid Combolist: Leaked in 2025, Still a Risk Now

HEROIC analysts identified a combolist called "Poland valid uploaded by a Telegram User" that traces back to March 2, 2025. The file contains 197 records, each pairing an email address with a plaintext password and a linked URL. Although it is more than a year old, the credentials inside remain fully readable and usable today.

Why a 2025 Combolist Still Poses a Risk Today

A leak dating back to March 2025 is not old news to an attacker, it is simply a file waiting to be tried. Because the passwords in this list were never encrypted, they read exactly the same now as the day the list was compiled. Anyone who has not changed the password tied to one of these 197 accounts is just as exposed today as they were when the file first appeared.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linked to the accounts

Why This Matters

Even a small, older combolist like this one feeds the same credential stuffing tools used against much larger breaches. Attackers test each email and password pair against banking, email, and social media logins, hoping the credentials were never changed and were reused elsewhere. That leaves anyone in this file at risk of account takeover, identity theft, and financial fraud, regardless of how much time has passed.

How Combolists Work

A combolist bundles email-and-password pairs into a single file for easy reuse by attackers, and this one was labeled "valid" to signal that the credentials had been checked and were working logins at the time it was uploaded to Telegram. Because the data was never encrypted, no cracking or decryption step separates the file from someone trying to log in with it.

Check If You Are Affected

Old leaks can still cause new problems if a password was never changed. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including this combolist and every other stealer log, combolist, and database dump HEROIC has indexed, so you can find out and secure any account still at risk.
