Black Hat Bash - Bash Scripting for Hackers and Pentesters (Early Access) (Dolev Farhi, Nick Aleks)

R ECON N A ISSA NC E

Every hacking engagement starts with some form of

information gathering. In this chapter, we’ll perform

reconnaissance on targets by writing bash scripts to run

various hacking tools. You’ll learn how to use bash to

automate tasks and chain multiple tools into a single

workflow.

In the process, you’ll develop an important bash-scripting skill:

parsing the output of various tools to extract only the information we

need. Your scripts will interact with tools that figure out what hosts

are online, what ports are open on those hosts, and what services

they are running, then deliver this information to you in the format

you require.
