alt Hacker News> The fan downloads its root CA cert over plain HTTP. It was always MitM-able.
The most fascinating part of this wave of LLM reverse engineering is seeing how many weird and poor choices were lying in plain sight.
Any number of people could have discovered and exploited this, but it’s tedious work. Most people who can do this are busy with their job and other things. Now LLMs enable people who understand these things to quickly get through the tedious parts, so they can do a lot more of this work in their free time than they could before.

Similarly, how easy things are for more people to do. I'm certainly not advocating for pulling in a root CA over HTTP, but before LLMs could make this knowledge trivial, how many people would even think to look at that angle. It's democratizing in an interesting way.

Would love to understand the decision-making behind this at Coway (or their firmware contractor). Anyone care to guess why someone would make this choice?
