Blackhills Information Security released a Powershell version of the DNSCAT2 client.   DNSCAT2 is a popular command and control tool that uses the DNS infrastructure to control hosts inside a tightly filtered perimeter.   This new DNSCAT2 client is a Powershell implementation of the popular tool and will certainly be a hit with penetration testers.
