As millions of people rush to join the Pokémon Go augmented reality game, questions are being raised over how secure the app is, given the amount of sensitive personal information it collects.
Microsoft programme manager and engineer Dennis Delimarsky noted that it is possible for attackers to directly connect to Pokémon Go application programming interfaces on shared networks such as public Wi-Fi.
An attacker in a so-called Man In The Middle position on such networks could observe, capture and modify the data Pokémon Go sends and receives, lure players to wrong locations and otherwise abuse the game.
This is because Pokémon Go doesn't use the certificate pinning security feature for the game's HTTPS traffic to and from Niantic servers that prevents impersonation.
Attackers could potentially gain access to a large amount of sensitive personal information via Pokémon Go.
