Hackers reportedly leaked 32 terabytes of secret Windows 10 code
32TB of Windows 10 internal builds, core source code leak online
Finding exploitable bugs suddenly easier
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.

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.
Spokespeople for Microsoft declined to comment. ®
Updated to add
Beta Archive's administrators have removed, or are in the process of removing, all traces of 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 the 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.
