Czech Republic Threat Landscape Report 2025

Key Insights from the Czech Republic’s Cyber Threat Landscape

Cross-Border Threat Activity Dominates:
Only a small share of dark web and ransomware activity is exclusive to the Czech Republic, with the majority connected to multi-country operations. This reflects the transnational nature of today’s cybercriminal ecosystem and the exposure created by interconnected regional infrastructures.

Financial Sector Under Pressure:
Finance and Insurance is the most targeted industry, representing the largest share of dark web exposure. Public Administration and Information Services follow, showing persistent interest in sectors handling sensitive citizen and business data.

Dark Web Markets Prioritize Data Sales:
Data leaks account for more than half of all dark web activity, underscoring attackers’ focus on monetizing stolen information. Access listings are also significant, highlighting ongoing demand for footholds inside corporate networks.

Rising Phishing Activity:
Phishing campaigns most frequently target financial institutions, followed by enterprise and holding companies. Threat actors often impersonate platforms such as Telegram Web, Google services, and major document-sharing tools to harvest credentials and launch follow-on attacks.

Significant DDoS Threat Levels:
The Czech Republic recorded tens of thousands of DDoS attacks within the reporting period, with peak bandwidths exceeding 1 Tbps. These incidents highlight a sustained threat to service availability across industries.

Why This Report Matters

Organizations in the Czech Republic face a broad and dynamic threat landscape shaped by cross-border attackers, escalating data leaks, and increasingly sophisticated phishing and DDoS operations. Proactive monitoring, early threat detection, and intelligence-driven defense strategies are essential to protect critical services and maintain resilience.
