Bitlocker is only good to protect info on a laptop from theives.
As it is, the tools in this story are only good for extracting keys from computers that are running and logged into the encrypted volume.
Still, I wouldn’t put it past MS to engineer a backdoor into their encryption technologies.
They ALWAYS have. Microsoft has yet to produce any product with encryption that did NOT have a backdoor for the cops, or anyone sufficiently motivated to steal the tool from a cop.
Microsoft has ALWAYS puts backdoors in their products. It's what they do. Fish gotta swim, birds gotta fly. Microsoft writes code with backdoors.
Which wouldn't be so bad, except that they don't make the backdoors secure either.
