Executive Summary
AI-generated
In August 2026, Russian hackers successfully phished EU officials using messaging apps such as WhatsApp and Signal. The attackers impersonated the official support team or chatbot to trick targets into providing their account PINs or scanning QR codes that linked their devices to their accounts. This incident is part of a trend among state-sponsored threat actors from Russia, China, and Iran, who are shifting their phishing campaigns away from email due to its visibility in security monitoring and the ability for messages to be deleted. The attacks affected at least 8 EU governments, including Germany and the Netherlands, targeting high-ranking officials in military, diplomacy, and politics.
Technical Mitigations AI-generated
• Network Intrusion Prevention (ATT&CK mitigation for Phishing): Network intrusion prevention systems and systems designed to scan and remove malicious email attachments or links can be used to block activity. • Restrict Web-Based Content (ATT&CK mitigation for Phishing): Determine if certain websites or attachment types (ex: .scr, .exe, .pif, .cpl, etc.) that can be used for phishing are necessary for business operations and consider bloc • User Training (ATT&CK mitigation for Social Engineering): Reduces success of phishing/vishing/impersonation and modern “human interface” lures. • Audit (ATT&CK mitigation for Social Engineering): Enables correlation of email/identity/SaaS/endpoint activity that appears legitimate. • Reset credentials and API keys that may have been exposed, and review access logs for the affected accounts or integrations.
