Read the article. It’s pretty clear that this is a backdoor, and calling it a bug would be so generous as to be misleading.

It seems undeniably a backdoor, why on earth would a very specific folder/file name and a specific boot combination just "magically" open up an encrypted drive.

It also doesn't help this comes from a person who likely was close to the development at Microsoft (one way or another) as their recent disclosures are quite alarming.

Of course, this could technically be the stars aligning type bug, but it seems like a purposefully planted backdoor to me.

*in your opinion.
