First time that I heard about an AI trying to spot a malware used for crypto jacking. It says it also focus on supercomputers but maybe it could also be implemented for desktop as well. Good if they could develop and make improvements, but they admit that this graph based approach couldn't capture all scenarios.
How hard can it be to detect that you computer is under full load even when idle or just doing some non-intensive tasks? Your fans will get louder, you might notice some heat, your performance will slow down.
And even for supercomputers, I doubt that AI is requires or is the best solution. They too can measure their load and detect suspicious processes, and if that is not enough, they can target crypto mining specifically, as it should leave a specific signature.
