Quick tools to perform Server Auditing

latest-release · Feb 1, 2020

Once in a while it's important to perform Auditing on your servers to ensure that you are up to date and there is no information you are protecting lurking out on the darkweb.

Today am going to discuss when you theHarvester one of the top OSINT tools for auditing your servers and your Organization external threats.

TheHarvester is a tool designed to be used in the early stages of penetration testing. It is an opensource intelligence tool, that gathering information from opensource tools online, it supports of 20+ public sources some of those sources include;

google
bing
baidu
censys
securitytrail
....and more....

Some of the main features these OSINT tools theharvester include;

Names ( for people from social networks)
Virtualhost
Subdomain finder
IPs
Port scanning
Emails

Installing theHarvester

Code:

pip3 install theHarvester

Installing theHarvester using virtualenv

Code:

sudo apt-get install python3-pip
sudo pip3 install virtualenv

#
# Create virtualenv

virtualenv venv

# Or create a python version specific virtualenv

virtualenv -p python3 myenv
#
# Now clone the git repo
git clone https://github.com/laramies/theHarvester.git
#
pip3 install -r requirements.txt
#
# Wait until the installation is done.

Usage

Code:

$
$ ./theharvester.py # If you cloned from github
$ # or
$ theharvester # if you installed using pip3 install theHarvester
$

There are more to this tool you can explore by yourself

eva2000 · Feb 1, 2020

wow thanks for heads up on this tool. Looks very interesting. Seems you're instructions are for Ubunut/Debian ? Problem for Centmin Mod users is they'd use CentOS and CentOS 7 only has native Python 2.7 and addons/python36_install.sh is highest version installed via IUS Community Yum repo for Python 3.6.

From their github repo's wiki install guide you need Python 3.7+ for it to work laramies/theHarvester. So Centmin Mod and CentOS 7 won't have the required Python 3.7+ versions for such an install. However, you can install Python 3.7 manually too and seems to work in running theHarvester tool.

If folks want to try this on CentOS 7 with Centmin Mod, I'd test on a test VPS these steps rather than on live site VPS so as to not screw anything up. Easy enough just spin up a test hourly billed VPS host like vultr, digitalocean, linode or like highly recommended Upcloud - signees also get US$25 credits to use as well

Install Python 3.7 first.

The compilation can take a long time to install especially on slow servers or single cpu threaded servers - could take hours on very slow servers!

Code (Text):

# update Centmin Mod code
cmupdate

# pip doesn't like ccache so disable it
export CC='gcc'
export CXX="g++"

# pip needs a tmp directory that doesn't have noexec restrictions

chmod 1777 /home/piptmp
export TMPDIR=/home/piptmp

Installation at your own risk, so try only on test VPS and not live servers.

Great compilation instructions. Though I thought python2.7 has already been dropped by all

eva2000 · Feb 4, 2020

Nope IIRC Redhat/CentOS 7.x has python 2.7 until 2024 and Redhat/CentOS 8.x is python 3.6 Python in RHEL 8 - Red Hat Developer
