Dutch Intel Warns of Russian Hackers Hijacking Signal, WhatsApp Attacks

Dutch intelligence agencies (AIVD and MIVD) warn that Russian-state actors are conducting a global campaign abusing support-chatbot impersonation and the linked-device feature on Signal and WhatsApp to steal six-digit verification codes and hijack accounts. Targets include government officials, soldiers, and journalists; the aim is to read private messages for espionage. The advisory emphasizes that the apps themselves are not compromised but individual accounts are at risk, and recommends using authorized channels for sensitive communications.
