Heaps of Windows 10 internal builds, private source code leak online
The Register ^ | Jun 23, 2017 | Chris Williams

Exclusive A massive trove of Microsoft's internal Windows operating system builds and chunks of its core source code have leaked online.

The data – some 32TB of official and non-public installation images and software blueprints that compress down to 8TB – were uploaded to betaarchive.com, the latest load of files provided just earlier this week. It is believed the confidential data in this dump was exfiltrated from Microsoft's in-house systems around March this year.

The leaked code is Microsoft's Shared Source Kit: according to people who have seen its contents, it includes the source to the base Windows 10 hardware drivers plus Redmond's PnP code, its USB and Wi-Fi stacks, its storage drivers, and ARM-specific OneCore kernel code.

Anyone who has this information can scour it for security vulnerabilities, which could be exploited to hack Windows systems worldwide. The code runs at the heart of the operating system, at some of its most trusted levels. It is supposed to be for Microsoft, hardware manufacturers, and select customers' eyes only.

In addition to this, top-secret builds of Windows 10 and Windows Server 2016, none of which have been released to the public, have been leaked among copies of officially released versions. The confidential Windows team-only internal builds were created by Microsoft engineers for bug-hunting and testing purposes, and include private debugging symbols that are usually stripped out for public releases.

This software includes, for example, prerelease Windows 10 "Redstone" builds and unreleased 64-bit ARM flavors of Windows. There are, we think, too many versions now dumped online for Microsoft to revoke via its Secure Boot mechanism, meaning the tech giant can't use its firmware security mechanisms to prevent people booting the prerelease operating systems.

Also in the leak are multiple versions of Microsoft's Windows 10 Mobile Adaptation Kit, a confidential software toolset to get the operating system running on various portable and mobile devices.

Netizens with access to Beta Archive's private repo of material can, even now, still get hold of the divulged data completely for free. It is being described by some as a bigger leak than the Windows 2000 source code blab in 2004.

A spokesperson for Microsoft said: "Our review confirms that these files are actually a portion of the source code from the Shared Source Initiative and is used by OEMs and partners." ®

Updated to add

Beta Archive's administrators are in the process of removing non-public Microsoft components and builds from its FTP server and its forums.

For example, all mention of the Shared Source Kit has been erased from its June 19 post. We took some screenshots before any material was scrubbed from sight. You'll notice from the screenshot above in the article and the forum post that the source kit has disappeared between the Microsoft Windows 10 Debug Symbols and Diamond Monster 3D II Starter Pack.

The source kit is supposed to be available to only "qualified customers, enterprises, governments, and partners for debugging and reference purposes."

In a statement, Beta Archive said: "The 'Shared Source Kit' folder did exist on the FTP until [The Register's] article came to light. We have removed it from our FTP and listings pending further review just in case we missed something in our initial release. We currently have no plans to restore it until a full review of its contents is carried out and it is deemed acceptable under our rules."

Windows App Store, search for the classic windows games. They are all available free from Microsoft. Or since it’s Windows 10, type something like Mahjong on the search box (lower left) and if you have it installed it will come up, otherwise it will present a link to the app in the store for you. Hope this helps.

"How the heck does somebody "walk off" with 32TB -- 32 Terabytes -- of secret data, without getting noticed? "

REALLY BIG thumb drive?

> REALLY BIG thumb drive?

Well, humor aside, I've seen ads for 1TB USB Flash drives (~$150), and they're bulky. 32 of them?

Transferring the data, even at screaming rates (say, 100MB/sec continuous), you're looking at 90+ hours. Big window to get caught in.

Not impossible, but not likely.

Sometimes you just have to sleep on it and the solution floats back up to a conscious level. ;)
