1k Poland Lines Leak: Who These 873 Exposed Logins Target

What HEROIC Analysts Found in the "1k Poland Lines" Leak

HEROIC's dark web monitoring team found a file titled "1k Poland lines" uploaded to Telegram and dated August 2, 2025. It is a combolist containing 873 records that pair email addresses with plaintext passwords, along with the URLs of the accounts each login belongs to.

Why This Leak Is Dangerous

Even a relatively small file like this one is dangerous because the passwords are stored in plaintext and matched directly to the sites they unlock. An attacker does not need to break any encryption, only to open the file and start testing the listed email and password pairs against the linked URLs.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linked to each account

Who These 873 Records Target

Small, targeted combolists like this one are often assembled and traded specifically because of who is on the list, rather than for sheer size. If your email address happens to be one of the 873 entries, you are just as exposed as someone caught up in a much larger leak, since the same credential stuffing risk applies no matter how big the file is.

Why This Matters

Attackers use lists like this to run credential stuffing attacks, testing the same email and password combination across banking sites, email providers, and social media platforms in the hope that the victim reused a password. A single successful match can lead to account takeover, identity theft, or financial fraud.

How Combolists Like This One Work

A combolist is a compiled file of stolen or leaked email and password pairs, often gathered from older breaches or infections and grouped together for distribution. Smaller combolists like this 873-record file are frequently shared on Telegram to build a criminal's reputation or to offer a free sample before selling larger collections.

Check If You Are Affected

Do not assume a small leak means low risk. HEROIC's free breach scanner checks your email against more than 400 billion leaked records, including combolists like this one, so you can find out in seconds if you were included. If your information turns up, change your password immediately and avoid reusing it anywhere else.
