Installing the packages on a Ubuntu 18.04 system
In the coming weeks I will be writing more about how to check the perimeter of your network, understand what data is leaking out from it, and how to safeguard your network, and especially your wallet from bad actors. These tools are the beginning, I will wrap it altogether piece by piece.
Log into your Ubuntu rig
Install zmap and zgrab
sudo bash
apt install zmap
apt install golang-go
go get github.com/zmap/zgrab
cd /home/USERNAME/go/src/github.com/zmap/zgrab
go build
Test it by running the following from a remote system, against your network
zmap -p 30303 (Your Public IP Here) –output-fields=* –output-file=results.csv | zgrab –port 30303 -banners –output-file=banners.json
