Unpatchable: 32C3 edition

Gradually we are all becoming more and more dependent on machines, we will be able to live longer with an increased quality of life due to machines integrated into our body. However, our dependence on technology grows faster than our ability to secure it, and a security failure of a medical device can have fatal consequences. This talk is about Marie's personal experience with being the host of a vulnerable medical implant, and how this has forced her to become a human part of the "Internet-of-Things".
