Well this greatly depends on how attached you are to your job. If you should get fired next week, how much trouble would you be in? In any case, before you start doing "malicious compliance" or other things, make sure you have a realistic fallback plan.

Secondly, before doing anything else, first be a professional and go talk to your manager. What is the reason behind this new policy? There could be things going on that you know nothing about which, if you were management, would cause you to make such a decision as well. Perhaps you can perform as expected while working from home, but maybe too many of your coworkers can't. It's hard to then say "you three may work from home, but you four may not".

Having said that, if you want to do some malicious compliance then start by really knowing what you're supposed to do and what not. Stop doing everything that's not your official job. Increase your response times on messengers and mail. Answer "tentative" to all meeting requests, then randomly not show up at some meetings, then say "I didn't accept". Stop doing anything outside of work hours and outside of the office.

Hope this helps,
