  • The main things are removing the cellular connection and disabling the connection back to the Tesla services. Back in the old days you could pull the SIM card, root the center and driver’s displays, setup firewall rules to block traffic to/from the Tesla servers, and disable the VPN.

    This is more difficult with the newer models. You can still pull the SIM, but would need to get creative for root access since it is a continuous game of whack-a-mole between the root methods and patches.



  • I set the VPN tunnel from the VPS to deny everything to the internal network by default, then put the services that need to be accessed on the allow list in the firewall. So the VPN endpoint from the VPS can only hit the very specific IPs/ports/protocols that were explicitly allowed. There is still the possibility of a compromise chain of VPS->service->container/VM->hypervisor->internal network access, but I feel comfortable with those layers.

    You could also setup an IDS such as Snort to pick up on that exploit traffic between the services and internal VPN endpoint if extra security is necessary on top of fail2ban and log alerts on the VPS.




  • Not sure if the /s was left off or this was a serious question.

    In the case it was a serious question, the first issue that comes to mind is when you seed clouds for one region, what happens to the next region downwind where the clouds would have rained without intervention? You are just moving the drought, there will still be a difference in the rain pattern somewhere.

    Seeding to generate more cloud cover at a global scale introduces a whole host of problems. Firstly, you lower the solar output which then means solar power generation will be less effective. That energy will need to be produced by some means, which right now fossil fuels would be the most likely to take up the deficit, increasing atmospheric carbon output. Then to compound problems further, the reduced solar radiation reaching the surface would have a number of impacts such as plant growth being slowed reducing their CO2 uptake, less moisture being evaporated for precipitation over land masses, wind patterns being changed, and wind speeds reduced which means even further reduction in renewable energy generation. So with today’s technology seeding clouds would end up compounding the issues in the long term and accelerate the already alarming changes.
