Review of social media traffic at the DNS resolvers and their security implementation.

The Domain Name System (DNS) is meant to make our lives easier, by giving names to IP addresses similar to the old phone books. Even though security extensions like DNSSEC are widely implemented, not all systems seem secure. This research will use real traffic logs of links posted on social media to analyze how the traffic behaves of big cooperate social media providers in particular: WhatsApp, Telegram, Reddit, Slack, and LinkedIn. Since social media platforms are kind of a black box, it is hard for the end user to detect whether the links they have sent are indeed secure. Especially when the query does not originate from the end user’s device, but rather from the servers of the social media providers. By analyzing the DNS(SEC) traffic, we concluded that certainly not all providers are secure in an attack scenario.
