Inside 10923 Poland KRDCLOUD: 10,645 Credentials Harvested

HEROIC analysts identified this stealer log on 21-Jul-2026. The breach exposed 10,645 records, with stolen data including email addresses, plaintext passwords, and URLs. The source is identified as 10923_Poland_KRDCLOUD.

Why This Is Dangerous

This log is geo-targeted, focusing on credentials harvested from users in Poland. With over 10,000 plaintext logins in a single file sorted by country, it becomes a precise tool for attackers who want to target Polish-speaking users on regional banking platforms, local e-commerce sites, and government portals. Geo-targeted logs are especially sought after because they allow focused, higher-success attacks on regional services.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the websites and services those passwords unlock

Why This Matters

For Polish internet users, a country-specific credential file like this poses layered risks. Attackers can target regional banking apps, local email providers, and Polish government digital services alongside international platforms. The consequences include credential stuffing, account takeover, identity theft, and financial fraud, all with a geographic focus that makes the attacks more efficient and harder for victims to detect.

How This Stealer Log Works

Malware designed to harvest credentials installs itself through cracked software, unsafe downloads, or phishing pages. Once on a device, it captures browser-saved usernames, passwords, and the website addresses those logins belong to. The KRDCLOUD distribution system then sorts the harvested data by country and makes it available to buyers on Telegram, where criminals select the region they want to target.
