According to Eastern Orthodoxy, is googling the serial numbers of a software and using cracks a sin?

I was raised in a little bit poor country where it's almost impossible for individuals to make online payments. No PayPal, Credit cards are for national use only and international use is very expensive. When I first started using computers, I used to hack or crack all the software that I use starting from the serial number or the activation of windows to the serial numbers of the photoshop, office, and even the smallest software. I've never done an online payment to buy any software because it's very expensive to buy them. I just checked the price of 3D max out of curiosity and it costs about $1,500 per year! That means I should work for a whole year without eating or spending any money to buy it. On top of that, I need to buy windows to be able to run it with an additional few months of working without eating. I know that all the reasons above are not an excuse to steal. But is cracking software and googling their serial numbers considered a sin? Has the Orthodox Church made any known pronouncements on this subject? I'm Orthodox so I prefer the answer to be from an orthodox point of view.
