TSforge: Reverse Engineering the Windows Software Protection Platform (opens in new tab)

Looks like this is the private key. They only had the image in the blog post, but the source on github has an RSA CAPI blob that has a well-known format, and I was able to get p and q from that and then rebuild the rest:

   >>> p 11318534160529108036253485236383567956736051114291832384964860497483944138627767735644927194447604146200949263506648764691264005869856504888238541661669931
   >>> q 13382005616182000286249448571069734158379697330449348896524695032496827828874510151220386742349656465839102989731103334890387932783643584970264741776141819

This key appears to match the text in the image:

I recall a former Microsoft employee stating that outside of enterprise Microsoft has stopped caring about pirated copies of Windows.

It's easy to believe given HWID give or take has worked since the release of Windows 10.
