Dutch AIVD and MIVD warn of a large-scale Russian nation-state campaign compromising Signal and WhatsApp accounts of government staff, military personnel, journalists and other high-value targets. Attackers employ impersonation (fake ‘Signal Support’ chatbot), phishing for SMS verification codes and PINs, and QR/link-based misuse of the messaging apps’ linked-device functionality; guidance for spotting compromises and mitigation steps is provided.
