The test specification just said "Firewall tests" so they're testing various scenarios involving the words "fire" and "wall" in some way
I am unable to imagine the need for any combination of dildo and "fire + wall" testing that makes any sense. The only thing I can come close to would be an internet enabled dildo that would keep track of running time and export it to a web site for your later annotation and review. But the very thought of that kind of privacy breach is about to give me hives...
There have already been, in our own universe, issues with privacy on internet connected sex toys. In 2016 it was shown that one connected vibrator sent customers' settings and usage information to the manufacturer's server without consent (the company eventually had to pay a settlement for that), and that third parties could access that information - and even take over the devices remotely. In 2017 another connected vibrator with a built-in camera was found to be hackable to give unauthorised people access to the video feed. In the same year it was discovered that one model of butt plug could be found and remotely controlled via Bluetooth.
As with other IoT devices, much of the market has little to no security, and for example will advertise themselves over Bluetooth to any nearby phone. Walk around your workplace with your Bluetooth explorer open and you might get a surprise or two. As is commonplace, the manufacturers tend to start paying attention to security after problems are found and publicised, not in the design stages, so at any one time there are lots of insecure products on the market.
Links are not hard to find, I'm just not going to search them up on my work computer (and can't be bothered manually copying them from my phone).
