The Netherlands' military intelligence service and domestic intelligence agency have issued a joint warning about a large-scale global cyber campaign targeting Signal and WhatsApp accounts of dignitaries, military personnel, and civil servants. According to the Dutch alert, Russian hackers are impersonating support chatbots to trick users into revealing their PINs, granting access to incoming messages.

This warning follows similar concerns raised by the Pentagon last year, which advised members not to use Signal after it was subjected to phishing scams by Russian hackers. The Dutch government's alert adds weight to these concerns, emphasizing the global nature of the threat. The hackers' tactics involve sophisticated impersonation techniques designed to exploit trust in official support channels.

With multiple national governments raising alarms about Signal and WhatsApp phishing scams, the message is clear: users must remain vigilant and never share security details or click links without verifying the sender's identity. This coordinated campaign highlights the ongoing cybersecurity challenges facing encrypted messaging platforms and the high-value targets Russian hackers are pursuing.
