Debugging symbols for most of those builds are available on symsrv.
The Windows Mobile Adaption kit (like the OEM Preinstallation Kits, OEM Adaptation Kits) is shared with a similarly sized audience, which used to include self-attested Microsoft Partners. Again, not confidential. Just gated stuff.
The Shared Source stuff is a slight unknown here because it's not clear what was in the ZIP. I presume this was a sampling of materials shared via the Shared Source Initiative (https://www.microsoft.com/en-us/sharedsource/), none of which includes high-value intellectual property, cryptographic code, third-party code, etc. It could still be damaging but Microsoft has clearly calculated the risk here; this stuff is shared with mere community MVPs.
So with all this knowledge, it's hard to digest the "omg more exploits coming" and "Microsoft lost 32TB of private IP" angles in The Register write up. I don't think there's a story here, frankly.
Do you consider windows installation images to be "compressed files" in this context?

Useful for research, and finding security issues. Not much else.
You can break patents without ever knowing the patent existed. So looking at this code wouldn't trigger a new patent problem.
And simply looking at some code, closing it, then later writing code that does the same functionality is not breaking copyright. So looking at this code would not trigger copyright.
Not a lawyer, though, but a quick search confirms this.
But what data does this 8TB refer to specifically? Is this the source + all the windows builds from a plethora of sources? Did you download 8TB of data from BA and expand it to 32TB or was this a figure provided to you by one of the raided hackers or their associates?
>think the bigger issue is not the final size, but that internal Microsoft material - particularly source code - has escaped into public FTP
Happens regularly, although usually it's MS employees leaving stuff in public FTPs or inside released ISOs, updates, whatever. redmond\ domain is huge and the (accidental or not) leaks never stop.
We've updated the story to explain why things aren't what they seem. Essentially, the files at the heart of the matter were there (we screenshotted them and saved copies of the forum posts) at time of writing, and they were removed later on Friday.
In terms of the 32TB: that's the full decompressed dump of Windows files uploaded to BA. From what I understand, Microsoft hasn't released 32TB of public Insider material, so obviously there's extra sauce in the mix.
That includes, yes, copies of officially released Insider builds plus confidential private stuff that should never have left Microsoft, let alone turned up in BA. We make this clear in the story - I'm starting to feel the headline could have been better to make this clearer rather than grabbing the biggest figure. I am beginning to regret this.
BA can twist and complain all it likes - but stuff that was confidential within Microsoft ended up in their FTP archive (and some is still in there, such as the ARM64 stuff). The next stage of this story will be to uncover how exactly did this material escape Redmond.
