Introduction Netcat is a tool that reads and writes data across network connections, using TCP or UDP protocol. Netcat has been referred to as the TCP/IP / networking swiss army knife. In this article we’ll look at different applications of netcat and how it can be useful in day to day activities of a pentester, security professional, sysadmin etc… If you would like to test out these commands in a lab environment without the need to install them on your own machine have a look at my scenario on CYBERRANGES using the link below.

netstat without netstat · Staaldraad

https://staaldraad.github.io/2017/12/20/netstat-without-netstat/

Recently I was doing an assessment in a locked down and restricted environment. One of the first actions you tend to do when landing a shell on a [linux] box is to do some reconnaissance. This is both on host and network, as you want to determine what new access this host has given you. Normally you would run netstat, ifconfig, ip route etc to determine if the compromised host is connected to any other hosts and to determine if there are other network segments you do not know about.
