Dutch intelligence agencies have issued warnings about a large-scale hacking campaign targeting users of encrypted messaging applications Signal and WhatsApp, which they attribute to Russian government-backed hackers.

The campaign appears to focus particularly on government officials and other high-profile targets, according to the Dutch intelligence assessment. The scope of the operation has been described as global in nature.

Signal has responded to the reports by stating that its systems remain secure. The company acknowledged it is taking reports of targeted hacking attempts against officials seriously, though it emphasized that the threats appear to target individual users rather than the platform's infrastructure.

The warning comes amid ongoing concerns about state-sponsored cyber operations targeting secure communication platforms used by government officials and activists. Both Signal and WhatsApp employ end-to-end encryption, making them popular choices for sensitive communications.

Dutch intelligence agencies did not provide specific details about the methods being used in the alleged Russian campaign or the number of potential victims. The assessment reflects broader Western intelligence concerns about Russian cyber activities targeting secure communications infrastructure.
