The laptops in use at my company have SIM card slots, which are actually used by some of our users. I am threat modeling our devices, so I was wondering if there are any realistic exploits that can be used on these laptops, no matter if the users use a SIM card or not.
According to this question, it is in theory possible for malware to be stored on SIM cards, although unlikely. This question was about phones, while I am asking about laptops, but I imagine that if an exploit for phones exists, then an exploit for laptops is also possible and maybe even likely. However, the answers only mentioned that it is possible in theory, but there were no examples given.
So, my question is if there are any real-life examples or just even proof of concepts for malware like this.
