Dutch and Portuguese intelligence agencies have warned that the Kremlin is conducting a global cyber campaign to infiltrate WhatsApp and Signal accounts of government officials, diplomats, and military personnel. Attackers are using various methods, including AI tools, to trick users into sharing passwords and access codes. While the platforms themselves are not compromised, the agencies advise against using them for sensitive communications. Signal and WhatsApp have confirmed their encryption remains secure but warn users against sharing personal information.
