On May 3, 2024, we discovered potential DNS leaks on Android due to bugs within the system affecting certain apps. After a Reddit user reported a DNS leak while using VPN, we conducted an investigation and identified scenarios where leaks can occur on Android devices. The leaks stem from direct calls to the C function getaddrinfo and affect apps like Chrome. We have found workarounds such as setting up a bogus DNS server until the issue is fixed by Google. These leaks can have serious privacy implications for users and may require additional precautions or avoidance of sensitive tasks on Android devices. Stay updated on our app for fixes.
