APP VULNERABILITY
Our network security analysis of the popular social media app, RedNote, revealed a number of issues with both the Android and iOS versions of the app.
MY2022, an app mandated for use by all attendees of the 2022 Olympic Games in Beijing, has a simple but devastating flaw where encryption protecting users’ voice audio and file transfers can be trivially sidestepped. Health customs forms which transmit passport details, demographic information, and medical and travel history are also vulnerable. Server responses can also be spoofed, allowing an attacker to display fake instructions to users.
COVID-KAYA, a platform used by frontline healthcare workers in the Philippines to collect and share COVID-19 cases with the Philippines Department of Health, contained vulnerabilities in both the web and Android apps that allows for unauthorized users to access private data about the app’s users, and potentially patient data.
This report examines the encryption that protects meetings in the popular Zoom teleconference app. We find that Zoom has “rolled their own” encryption scheme, which has significant weaknesses. In addition, we identify potential areas of concern in Zoom’s infrastructure, including observing the transmission of meeting encryption keys to China.
