PowerShell DNS Command & Control with dnscat2-powershell

**Executive summary:** This post describes dnscat2 and a PowerShell client implementation that enables DNS-based command-and-control (C2). It provides setup instructions, demonstrates PowerShell-specific features (interactive PS shell, in-memory script loading, file upload/download), explains encryption and authentication options, shows tunnel/port-forwarding usage, and discusses evasion techniques (timing delays, packet sizing, choice of DNS query types) to reduce detection likelihood.
