NÚKIB warns of Russian cyberattacks. Destructive threats are also said to exist.

The National Cyber and Information Security Agency (NÚKIB) warns of sophisticated cyberattacks by Russian state-sponsored actors targeting Czech and allied institutions. The primary focus is on cyber espionage against government, NGOs, private entities, and individuals. NÚKIB highlights the potential for destructive cyberattacks aimed at permanently damaging data or infrastructure. Attackers conduct broad internet scans for poorly secured devices and exploit vulnerabilities in email services using zero-click and half-click attacks. Phishing remains a dominant method, often tailored to government themes, with incidents reported where Russian actors impersonated the Czech Foreign Ministry. Phishing also spreads through messaging apps, leveraging social engineering tactics.
