The infection chain begins with a CAB archive in Windows Update storage and abuses AppDomainManager loading, crafted RESX/BinaryFormatter deserialization, and nested XAML payloads. It bypasses AMSI, removes logs and other forensic traces, checks for administrator access, then uses RPC and a deserialization exploit to move execution into dllhost.exe. Its plugin gathers system details, waits 20-40 minutes before contacting C2, and polls over HTTPS using encrypted, authenticated traffic; it supports several proxy-discovery methods and executes downloaded XAML in isolated AppDomains. Kaspersky observed one victim in Asia and could not attribute the activity to a known APT group. The researchers did not observe how the initial CAB was delivered. ### Source excerpt Kaspersky researchers analyze a complex targeted attack employing NetamLoader, a sophisticated malicious framework and targeting a customized government OS. ## UWP and WinUI 3 apps: UI testing with MSTest DevFeed: [UWP and WinUI 3 apps: UI testing with MSTest]() Original publisher: [Read original article]() Author: Amaury Levé Published: 2026-10-05T17:05:00Z Content type: tutorial Language: en Sources: [.NET Blog]() Topics: [ui-testing](), [Windows UI Library (WinUI)](), [Universal Windows Platform](), [mstest]() Tags: [microsoft-testing-platform](), [mstest](), [net](), [testing](), [ui](), [uwp](), [windows-app-sdk](), [winui](), [winui-3](), [xaml]() ### AI overview The article explains how to run MSTest UI tests for UWP and WinUI 3 apps using Microsoft.Testing.Platform.

It also shows how an observable sequence creates tiles at intervals and how DispatcherObservable.ObserveOnDispatcher schedules collection updates on the runtime dispatcher. ### Source excerpt I have a small WP7 project called Summarize. It is a fun math-based game (check it out for free). It has a nice effect of loading tiles. Several people has asked me how I have done it, so in this post I will cover how to build something similar on your own. Let's start with building the UI. We have the toolkit's WrapPanel inside the ItemsControl and a simple TileControl with TextBlock displaying the tile number. TileControl.xaml markup: Visible In the code-behind we start the animation when the tile is loaded: private void OnLoaded(object sender, RoutedEventArgs e) { var sb = Resources["LoadedStoryboard"] as Storyboard; if (sb != null) { sb.Begin(); } } MainPage.xaml m ## WPF/Silverlight visual states with DataTemplates DevFeed: [WPF/Silverlight visual states with DataTemplates]() Original publisher: [Read original article]() Author: Andrew Khmylov Published: 2010-11-19T00:00:00Z Content type: tutorial Language: en Sources: [Despite the odds]() Topics: [WPF](), [XAML](), [MVVM](), [User Interfaces]() Tags: [mvvm](), [progress](), [screen](), [state](), [threading](), [xaml]() ### AI overview This tutorial presents a WPF technique for switching among page, window, or control states by defining different DataTemplates. It contrasts this approach with VisualStateManager and Silverlight Activity Control, then demonstrates a welcome screen and a busy-progress state backed by a ViewModel. ### Source excerpt Consider a common task - you need to switch between different screens in your application, that represent various states (e.g. Normal/Loading/Error). How are you going to implement this? You can start with VisualStateManager and define appropriate visual states. Well, this will surely do the thing, but you will have to create lots of controls and manage their Visibility or Opacity. And what if you have a complex markup? And I suppose that switching the state will not remove invisible items from the visual tree. And even more, with VisualStateManager you are bound to Expression Blend, because, you know, it's not very convenient to edit VSM settings by hands in XAML (which I prefer, but it is a topic for another article). The second option that may fit well, if you just need something like "I'm busy!" overlay is Silverlight Activity Control. Works like a charm with RIA services, but I find it limited for complex scenarios (and it's not available for WPF). I've found another approach (it becomes especially useful with MVVM and improved DelegateCommand implementations - I will blog about this in a few days). The idea behind this technique is quite simple. You define different templates for different page/window/control states. Yeah, that's it. Let's start with our implementation. Our application will have only one page with 2 different states: A welcome screen, that hosts a button to start 'the heavy' calculation. Busy window" that shows information about the current processing progress. I decided to create a simple ViewModel as a backing storage for our UI properties. It has two properties - IsBusy that says whether some hard work is executing now, and Progress - simple execution progress indicator. Method StartCalculation runs a new thread executes a number of loop steps. On each step the executing thread is suspended for 100ms (to imitate a slow operation). Normally you will create a DelegateCommand that will handle all the execution logic, but I decided to keep thin
