Signal has issued a scam warning after Dutch intelligence revealed a Russia-backed campaign targeting high-profile users including government officials, military staff, and journalists. The hackers posed as Signal support staff to steal account details and hijack devices through sophisticated phishing attacks.

Dutch agencies MIVD and AIVD identified this "large-scale global cyber campaign" targeting people of interest to Russia. The attackers tried to trick users into sharing SMS codes and Signal PINs to gain account access.

Signal emphasized its systems remain secure but stressed that "user vigilance" is crucial. Experts warn that convenient features like QR code logins have become primary attack vectors for criminals targeting encrypted messaging apps.
