Now that we have a common understand of DNS, how it operates in a network, and the server-side tracing capabilities, let’s dig a little deeper into the tunneling capabilities. In this section we will describe how command and control (C2) beacons can operate over DNS, and how data exfiltration and infiltration is possible. C2 The fifth-level subdomain is a data sequence number that allows the C2 server to reassemble the data, which will start with 1 and increment by 60 as the DNS tunneling protocol sends 60-bytes of encoded ciphertext within each DNS request. Detecting DNS Tunneling SANS.edu Graduate Student Research by Greg Farnham - March 19, 2013 . Web browsing and email use the important protocol, the Domain Name System (DNS), which allows applications to function using names, such as example.com, instead of hard-to-remember IP addresses. Most of the other DNS Tunneling tools focus on tunneling TCP traffic using DNS, but this tool is different. DNScat2 [6] is designed to create an encrypted command and control channel over the DNS. It borrows some concepts from Metasploit’s handler and is made with ease of use in mind. Nov 22, 2019 · DNS tunneling is a non standard solution to exchange data using the DNS protocol. It can be used to extract data silently or to establish a communication channel with an external malicious server in the case of a Command and Control (C&C) exchange. Other systems: Windows, Mac OS X, Unix, Linux & Docker The VPN-over-DNS Windows and Mac OS X versions are named the Value Pack and both are available for free for our Android users: to install a DNS VPN client on your Windows laptop, click here, and on your Mac OS X laptop, click here. The Value Pack is based exactly on the same code than the
By default, the 6to4 tunneling protocol is enabled in Windows Vista, Windows Server 2008 or later versions when an interface is assigned a public IPv4 address (that is, an IPv4 address that is not in the ranges 10.0.0.0/8, 172.16.0.0/12, or 192.168.0.0/16). 6to4 automatically assigns an IPv6 address to the 6to4 tunneling interface for each such

The Value Pack is based exactly on the same code than the There is a Java implementation that works on Windows on analogbit.com: tcp-over-dns. tcp-over-dns contains a special dns server and a special dns client. The client and server work in tandem to provide a TCP (and UDP!) tunnel through the standard DNS protocol. This is similiar to the defunct NSTX dns tunelling software.
Improved Windows PowerShell Support. New Windows PowerShell cmdlets are available for DNS Server. For more information, see What's New in DNS Server in Windows Server 2016. GRE Tunneling. RAS Gateway now supports high availability Generic Routing Encapsulation (GRE) tunnels for site to site connections and M+N redundancy of gateways.
