European Union cyber defense units have identified state-sponsored spearphishing campaigns targeting the messaging accounts of high-ranking officials. These attacks utilize social engineering techniques, such as impersonating support chatbots, to trick users into clicking malicious links or opening compromised attachments via applications like WhatsApp and Signal.

EU authorities have officially linked these activities to Russian threat groups. In response to these security risks, European cybersecurity services have advised governments to move away from commercial messaging applications for official business. By late August 2026, the EU had recorded eight significant cyber incidents, highlighting vulnerabilities in how institutions manage access credentials and exchange sensitive documents.
