Welcome to Pluralsight and this Read Team tools course featuring
dnscat2, the open‑source DNS tunneling tool developed and maintained
by Ron Bowes. As the Red Team operator,
you may have come across scenarios in which access from the compromised
systems to your C2 infrastructure becomes restricted.
This is where dnscat2 comes into play,
enabling you to set up a command and control channel over an
encrypted DNS tunnel between a compromised machine and an
authoritative DNS server that is under your control.
Using dnscat2, you will be able to bypass firewalls
by traversing the DNS hierarchy.
The principle behind dnscat2 is quite simple.
It takes advantage of legitimate use of name resolution,
which is allowed outbound in order for systems to actually reach the internet.
Whether you're looking to enhance your capabilities during Red Team
operations or just to test your environment's defenses against complex
adversarial techniques, join me as we'll set up dnscat2 on an authoritative
domain to exflitrate data from a target system.
