A project demonstrates how to create single files that function as both bash and PowerShell scripts, replacing curl-based installers with portable HTTP tools. The approach enables secure, verified installation across Unix, Windows, and embedded systems without external dependencies, with each tool under 5 kB and readable before execution.
Fake GitHub repositories with misleading names are distributing malware through PowerShell commands that execute multi-stage scripts. The attack uses DLL sideloading to deploy a stealer that harvests credentials from browsers, Discord, Steam, and gaming platforms while displaying fake installer progress messages.
