One hint on how fast detection happens on a miner in a business that is properly secured is an alert happens within 5 seconds of the miner being attempted to execute and the miner is not able to execute, so you lose your job over zero profit. Considering the cost of the job loss the math turns to a loss for attempting this at work.
you clearly overlooked the fact that a vpn is a typical solution to staying anonymous.... [and i'm not here to nitpick on hypotheticals]
I know this works even today, because I installed several miners at [insert silicon valley corporate company's name here] on a rack designated for his department.... and they have strict rules as well.
