Researchers analyzed a signed fake “Google Workspace” MSIX that uses an .appinstaller file to obtain a server and ID, then runs server-supplied PowerShell via WebView2. The final payload was unavailable; a traffer connection is only a suspected fit.

Signed Fake Google Workspace MSIX Installer Abuses WebView2 to Execute Remote PowerShell Commands + Video
A digitally signed fake Google Workspace installer is being used in a suspicious software distribution campaign, with researchers uncovering a multi-stage execution mechanism that allows attackers to retrieve infrastructure details and execute PowerShell commands supplied remotely by a server. The investigation highlights how attackers can abuse legitimate Windows application deployment mechanisms, trusted software signatures, and Microsoft's WebView2 runtime to make malicious activity appear more like routine application installation and execution.

I'll get it working on Windows first with external tooling for the MSIX-packaged SQLite database, but I have all the means to make this 100% cross-platform in a second step. I've got a lot of the building blocks in github.com/Devolutions/... already for the code signing part

Dev log: one em dash closed a string in our build script. Windows PowerShell 5.1 read the BOM-less UTF-8 file as ANSI, so the dash's last byte (0x94) became a curly quote, which PowerShell accepts as a closing quote. Fix: ASCII '--'. ParseFile: 4 errors before, 0 after. #indiedev #powershell #utf8
