DNS Goisoner 🤮

An on-path DNS poisoning attack tool, written in Golang.

Developed using the GoPacket library, supports just plain (UDP) DNS traffic over port 53.

DNS Goisoner captures the traffic from a network interface in promiscuous mode, and injects forged responses to selected DNS A requests with the goal of poisoning the cache of the victim's resolver.

Parameters & Usage 💬

DNS Goisoner has three parameters and usage for this:

go run dnspoison.go [-i interface] [-f hostnames] [expression]

• -i : Listen on network device (e.g., eth0). If not specifed, default interface (eth0) will be used.
• -f : Read a list of IP adress and hostname pairs specifying the hostnames to be hijacked. If '-f' is not specified, DNS Goisoner will forge replies to all observed requests with the chosen interface's IP address as an answer.
• : It is an optional argument. It is a BPF filter that specifies a subset of the traffic to be monitored. This option is useful for targeting a single victim or a group of victims.

Example Hostnames & Usages

Hostnames file should contain one IP and hostname pair per line, seperated by whitespace, in the following format:

100.90.80.70      ex.example.com
10.9.8.7          amp.example.com
192.168.62.27     le.example.com

Example usages:

sudo go run main.go -i ens33 -f targets.txt

sudo go run main.go -i ens33

sudo go run main.go -i wlan0 -f targets.txt "dst host 192.168.2.10"
