Dark Web Intel: 351 Credentials From the KRDCLOUD Poland Leak

HEROIC analysts identified a stealer log dataset, tracked as 352_Poland_KRDCLOUD, that a Telegram user uploaded on 16-Jul-2026. The file contains 351 records pulled from infected devices, including email addresses, plaintext passwords, and the login page URLs tied to those accounts. The naming suggests the data was organized as part of a batch tied to Poland.

Why This Is Dangerous

This file gives attackers everything needed to log into an account without cracking a single password. Each of the 351 records pairs a working email address and plaintext password with the exact site it opens, ready for immediate use the moment someone downloads the file.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the associated login pages

Why This Matters

A file of 351 records is small in scale, but the risk to each account is the same as in much larger breaches. If a password from this leak is reused on another account, attackers can use it for credential stuffing, account takeover, and in more serious cases financial fraud or identity theft.

How Stealer Logs Work

Stealer log malware infects a device, often through a fake download, cracked software, or a malicious attachment, and quietly copies saved browser passwords, autofill data, and session details. The stolen data is then organized into labeled batches, in this case one numbered and tied to a specific cloud service and region, before being shared through Telegram channels that trade in fresh dark web intelligence like this.
