How do sideloading techniques work in today’s runtime environment? Join us for a free one-hour BHIS webcast with Matthew Eidelberg on proxy execution via Microsoft Edge WebView2. Matthew will break down techniques that blur the line between legitimate app behavior and malicious activity, showing how shared runtime components are changing execution and detection boundaries. You’ll learn how traditional sideloading concepts apply in modern environments, how WebView2 is increasingly embedded across the ecosystem, and how attackers can exploit it to bypass common detection methods. 🛝 Webcast Slides https://www.blackhillsinfosec.com/wp-content/uploads/2026/04/Proxy-Execution-with-Microsoft-Edge-Webview2.pdf Chapters 00:00 - Intro - Proxy Execution with Microsoft Edge WebView2 - Matthew Eidelberg 00:49 - Agenda 01:31 - DLL Hijacking 04:48 - DLL Proxy Attacks 06:05 - Execution Flow 07:17 - Windows Apps 12:05 - What is WebView2? 13:21 - Webview Security Issue 16:42 - Domain_action.dll 20:01 - Weaponizing the Flaw 22:38 - Tooling - FaceDancer 24:11 - FaceDancer - Usage 25:32 - FaceDancer - Examples 27:06 - FaceDancer - Common Questions 30:00 - FaceDancer - Caveats 30:44 - Microsoft's Response Timeline 34:04 - Microsoft's Disclosure Process 36:29 - Defensive View 38:37 - Wrap Up 39:49 - Q&A Chat with your fellow attendees in the BHIS Discord server: https://discord.gg/bhis ( https://discord.gg/bhis ) in the #🔴live-event-chat channel 🔗 Register for FREE Infosec Webcasts, Anti-casts & Summits – https://poweredbybhis.com Brought to you by:Black Hills Information Security https://www.blackhillsinfosec.com ☯️ Introducing BHIS Fusion Penetration Testing https://www.blackhillsinfosec.com/fusion-penetration-testing/ Antisyphon Training https://www.antisyphontraining.com Active Countermeasures https://www.activecountermeasures.com Wild West Hackin Fest https://wildwesthackinfest.com BHIS Webcasts Episode 10 July 10, 2026 ★ Episode details: https://share.transistor.fm/s/baffa913 ★ Additional episodes: https://bhispodcasts-webcasts.transistor.fm
