"It is impossible to hack a Trezor without being able to touch the Trezor. It doesn't matter if it is connected to your computer, and the hacker has control of your computer. They won't be able to physically touch/press the confirm button the Trezor. (Nor would they be able to put in the pin number if it is a model T) Now, if you have your seed phrase saved on your computer... that's a different story."
