Other Western governments have advised officials not to download the app, said another official from a European government. All of the officials spoke on the condition of anonymity to discuss international government deliberations. The potential vulnerability from the Android app, which has been downloaded thousands of times and provides a gateway for participants at COP27, was confirmed separately by four cybersecurity experts who reviewed the digital application for POLITICO. The app is being promoted as a tool to help attendees navigate the event. But it risks giving the Egyptian government permission to read users’ emails and messages. Even messages shared via encrypted services like WhatsApp are vulnerable, according to POLITICO’s technical review of the application, and two of the outside experts.
