This week KeenLab made public the result of their research on hardware and software of BMW vehicules . In a nutshell, they found 14 vulnerabilities, counting 5 with a remote access vector. It’s not really surprising but now that is official I feel really worried about it. How do you feel?
On a brighter note, I hope you’ll like this week selection of articles. All of them curated for your pleasure. Enjoy the issue #71!
