When is hacking another computer illegal?

but dont professionals use hacing to fix other people’s computers from like far away? the microsoft people do it all the time and i dont think thats illegal

Yes, but that is not hacking, especially when it’s their servers or their own product. Most likely they ask for consent.

The term hacking means that you are doing the cyber-activity illegally. The moment when a person reaches and/or breaches through another party’s information without out their permission, that’s when the activity is considered hacking; illegal. Changing, modifying, looking, etc. files and settings is part of hacking. You can access public data like IP addresses and such without hacking, or it being illegal at all.

so you’re saying that there is absolutely no way possible that someone could hack another computer and have it be legal. like there isn’t even one special condition?

Asking for the owner’s consent would make it legal. Then that branches out.

Perhaps police work?

alright, i think i understand now. thank you for the information

That ultimately also leads to consent, by getting a warrant.

Ehm, when you begin to hack it?

i guess that will be a crime
