The Netherlands’ military and domestic intelligence have issued a warning that Russian hackers are behind a global cyber campaign targeting Signal and WhatsApp accounts of officials and military staff. The hackers are using fake chatbots to deceive these targets into sharing their PINs, giving them access to messages.
Hackers are using phishing tactics to target high-profile individuals by impersonating accounts like “Signal support” to gain access to their details.

A Dutch report reveals that Russian intelligence is trying to access Signal and WhatsApp accounts. Messages of Dutch government employees have already been compromised, and the report suggests that journalists may also be targets.
Last year, Google reported that Russian actors were attempting to phishing Signal accounts linked to the Ukrainian military and cautioned that this tactic might spread.
“We are aware of recent reports regarding targeted phishing attacks that have resulted in account takeovers of some Signal users, including government officials and journalists. We take this very seriously,” the company posted on social media, alongside an example phishing message.
Signal verifies users by texting their phone numbers but keeps these numbers hidden from each other for privacy. This can make scam messages appear more credible because users can’t check the sender’s phone number for authenticity.
A WhatsApp spokesperson declined to comment but recommended users never share their login information with other people and recommended its scam protection guide.
