Developer platform: Win32, .NET, Silverlight, XNA, DX . TV . OS (Media Center): Windows NT . OS (Xbox): NT-mutant . Developer platform Xbox: .NetCF/XNA on Win2K fork . Server and cloud . OS: Windows NT and Azure Convergence BENEFITS . Consistent developer story (internal/external) . No porting costs . Allow product groups to focus on customer value . Increased Agility . Innovation and bug fixes flow more rapidly . Engineering efficiency . Opportunity for improvements/cleanup Convergence OS Products Windows Windows Windows Mobile Servers Clients (Home, DNS (Enterprise, File Ultimate etc) / WinPE & Data Center Serv EV etc) DHC Friends er P Converged OS Mobile Client Server Core Core Core Presentation (DxCore, MFCore, etc) MinServer Core System Mincore Mincore PSPs Minwin Minwin PSPs One WHAT .

  • Microsoft and Cray to Unveil $25,000 Windows-Based Supercomputer
    AAll About Microsoft: l lCodeTracker A monthly look at Microsoft’s codenames and what they Areveal about the direction of the company. b o u t M i c r o s o f t : All About Microsoft CodeTracker Keeping track of Microsoft's myriad codenames is an (almost) full-time occupation. I know, as I spend a lot of my work hours tracking down the latest names in the hopes of being able to better keep tabs on what's coming next from the Redmondians. Each month, I'll be releasing an updated, downloadable version of the CodeTracker. I'll add new codenames -- arranged in alphabetical order by codename -- of forthcoming Microsoft products and technologies. I also will note timing changes (date slips, the release of a new test build, the disappearance of a planned deliverable) for entries that are already part of the Tracker. Once Microsoft releases the final version of a product or technology I've been tracking, I will remove it from the Tracker. In that way, the CodeTracker will remain focused on futures. (An aside about the Tracker: A question mark in place of an entry means I have insufficient information to hazard even an educated guess about a particular category.) If you have suggested new entries or corrections to existing ones, please drop me an e-mail at mjf at microsofttracker dot com. Thanks!

  • Universal Unhooking
    W HITE PAPER Universal Unhooking Blinding Security Software In both ‘good’ and ‘bad’ uses, hooks are inserted by overwriting the first few bytes of a target function to hijack execution flow. Code hooking is a technique used for redirecting a computer’s execution flow to modify software. Essentially, a ‘hook’ is something that will allow the developer to see, view, and interact with something that is already going on in the system. Code hooks can perform a wide variety of functionality, both innocent and nefarious, including: • Patching a bug • Performance monitoring • Disabling digital rights management systems • Capturing keystrokes (keylogging) • Hiding processes and files (rootkits) The antivirus (AV) industry uses code hooking to monitor processes for potentially malicious behavior, protect applications by injecting anti-exploitation checks, and isolate processes by sandboxing or virtualization. The technique can also be used by bad actors, for instance, to implement a rootkit to hide processes and network connections from the end-user and security software. Bad actors have also determined how to monetize the technique by hooking browsers to invisibly modify online banking sites to steal credentials or initiate fraudulent transfers. In both ‘good’ and ‘bad’ uses, hooks are inserted by overwriting the first few bytes of a target function to hijack execution flow. Typically, a JMP or CALL is inserted to transfer execution to new code that will perform the new functionality and, depending on the intended behavior, may return to the original function to complete its execution. Universal Unhooking | 2 A Pen Tester’s Perspective A Brief Detour: Code Hooking One of the first things a penetration tester performs The diagram below depicts the general outline of code after gaining initial access to a system is to dump hooking.
