In Europe and the US all new vehicles now have a visible ID under their front window glass, it’s called a VIN. It’s even standardized where it must be.
I'm pretty sure it should be possible if one really wants to do it. Think of a high-power IR flash and a high-res camera synchronized with the flash, with fixed focus on where the VIN would be passing. If the flash pulse is short but strong enough, it should be possible to read the VIN. Maybe some polarizing filters to remove glass reflections are needed.
You have to consider your machine and all others you connected to to be compromised. Time to reinstall every device with new accounts and passwords. With unused usb sticks and images downloaded from another network you were never connected to.
Mruby has something like that build in, you can create a VM which only has basic data types and control flow, no i/o, rng, time, meta programming or any host access possible simply because most functionality is only available as gems and they simply aren’t loaded. Everything you can do with it should be fully deterministic.
Isn't that fairly common? You could then put in some other address, but you could do the same thing by setting up your own mail server, and in the former case you're not even really anonymous because the headers are going to show it was sent through their mail server and their mail server's logs will show which account was used to send the message.
The email sent from your own separate server will fail basic dmarc/SPF/dkim validation the email sent by their own servers likely will appear legitimate
It would fail in the same ways unless the from address you're using is on their domains, which is then only a problem for their own customers rather than innocent third parties, and their own customers have the sensible option to stop using their service.
In Germany I'd be surprised if the police didn't come to your house when you did that, and take all your computers to find evidence you sent it, and you're not getting them back even if you're proven innocent.
A cursory Chromium code search does not find anything outside third_party/ forcing either signed or unsigned char.
I suspect if I dug into the archives, I'd find a discussion on cxx@ with some comments about how doing this would result in some esoteric risk. If I was still on the Chrome team I'd go looking and see if it made sense to reraise the issue now; I know we had at least one stable branch security bug this caused.
Yup, by default a Linux based router won’t forward any traffic to a IPv6 host unless you explicitly have a program running which keeps on telling the kernel you want that.
