The Netherlands’ military intelligence service and domestic intelligence agency have issued a join warning claiming that Russian hackers have launched “a large-scale global cyber campaign to gain access to Signal and WhatsApp accounts belonging to dignitaries, military personnel and civil servants.” According to the Dutch alert, hackers are imitating support chatbots to trick key targets into revealing their PINs for those communication platforms, which allows the bad actors to access incoming messages.

Last year in the US, the Pentagon advised members not to use Signal after the platform was subjected to similar phishing scams by Russian hackers. (Although the same US military leaders proved capable of creating their own security breaches without foreign interference just days prior.)

Having another national government raise concerns about Signal and WhatsApp phishing scams offers yet another reminder to never provide security details or click links without a check on who is really asking for your info.
