haven

If you have heard of [Haven](https://github.com/guardianproject/haven), then Tripwire fills in the void for a robust anti evil maid solution after Haven went dormant. The GitHub repo describes both the concept and the setup process in great details. For a quick overview, read up to the demo video. There is also a presentation of Tripwire available on the Counter Surveil podcast: https://www.youtube.com/watch?v=s-wPrOTm5qo

It's fiddly and annoying, the exact opposite of what you'd put in a movie, or even a boring novel. From my year in the (redacted) MoD, I still get bad memories of having to deal with stuff like https://www.3m.com/3M/en_US/p/d/b5005310025/ or rather the equivalent from twenty years ago... btw. is anyone working on Haven or a reboot (eg. looking at https://github.com/guardianproject/haven/issues/465)

Even better is something like the Guardian Project's Haven(https://github.com/guardianproject/haven) which IIRC Snowden contributed to. It's incredibly cost-effective to just buy an old Android phone (which comes integrated with multiple microphones, with good signal processing and noise cancellation), instead of building it with components. Haven is specifically designed for intrusion detection, and for preventing people from tampering with your laptop for instance by detecting activity on the Android phone's sensors.

There's Haven, a mobile app that does exactly that: help you detect Evil Maid attacks. https://github.com/guardianproject/haven https://en.m.wikipedia.org/wiki/Evil_maid_attack

Maybe more appropriate: "Wow, my phone can _optionally_ run an onion service!" https://github.com/guardianproject/haven/blob/0fd6f690ef6303...

> Whose Tor Onion Service? Wow, my phone runs an Onion service? Seems like it https://github.com/guardianproject/haven/blob/0fd6f690ef6303... I guess battery life is less of a concern for the suggested use case (e.g. turning a cheap, extra commodity device into a primarily stationary, plugged-in security system).
