The ‘335944_Poland’ Dump: 318,033 Login Credentials Surface Online

In July 2026, HEROIC analysts found a combolist file labeled 335944_Poland uploaded by a Telegram user. The file contains 318,033 records of email addresses, plaintext passwords, and login URLs. The numeric prefix appears to be a batch or lot number used by the uploader, and while the file name references Poland, HEROIC has not independently verified the nationality of the accounts involved. Why This Is Dangerous: With over 318,000 credential pairs stored in plaintext, this is a large enough list to be genuinely useful for automated attacks. Every password in the file can be tried against other websites immediately, with no cracking required. What Was Exposed: - Email addresses - Plaintext passwords - URLs of the original login pages Why This Matters: Large combolists like this one are commonly merged with other leaked data and used for credential stuffing, where bots test stolen logins against banking, email, and retail accounts at scale. If your email and password are in this file and reused elsewhere, other accounts tied to that password are at risk. How This Combolist Was Assembled: Sellers and forum users regularly package large batches of stolen or scraped credentials into numbered files like this one for distribution. The labeling convention, a number followed by a location tag, is typical of how these lists are catalogued and traded, though the label itself is not proof of where the affected accounts are based.
