The Poland Stealer Log: 1,162,723 Login Credentials Hit the Dark Web

HEROIC analysts identified this stealer log on 08-Jul-2026. The breach exposed 1,162,723 records, with stolen data including email addresses, plaintext passwords, and URLs. The source is identified as the Poland stealer log collection.

Why This Is Dangerous

At over 1.1 million records, this is an unusually large stealer log. Collections of this size are highly valuable to organized cybercriminal groups that run large-scale credential stuffing operations. Every record contains a ready-to-use email address, a plaintext password, and the URLs of sites the victim visited, making this dataset immediately actionable for account takeover campaigns across banking, email, retail, and social media platforms.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (websites and services accessed by victims)

Why This Matters

Breaches of this scale create lasting exposure. Once credentials are in circulation, they move through multiple underground marketplaces and Telegram channels, reaching new threat actors indefinitely. Victims face repeated intrusion attempts over time, not just immediately after the breach. Financial accounts, email inboxes, and any service sharing the same password are all at risk. The scale of this leak also increases the probability that entire families or organizations are affected.

How Stealer Logs Work

Infostealer campaigns often target specific geographic regions through localized phishing pages, malicious ads in local search results, or compromised software downloaded from regional websites. Once a device is infected, the malware extracts every saved credential and browser session it can find and transmits that data to attacker-controlled servers. Large regional collections like this one are then aggregated and sold as premium datasets in dark web markets.
