Information Gathering Part I: TheHarvesterDon't get left behind! Follow Xeus to get the latest in hacking. It is an easy-to-use open source tool built in python by Christian Martorella. Since it is just a python program, theHarvester can run on anything that can run python. We need to install a dependency, the requests library which is needed by theHarvester. Run the following command:. You should now be able to run theHarvester by referencing the python file from the command line:. S: For windows, use theHarvester. We see a bunch of options that we can use with the command along with a few examples. I want to see what comes up for XeusHack. This saves a file called xeus. Now we got a bit more data. We see a couple of email addresses and a bunch of subdomains. You can bet that kali. An indie developer or a small business may not have taken all the precautions to keep their website safe. In this case, the information that theHarvester turns up could be used to attack them. To understand how theHarvester could be used in a real-life setting, let us drift away for a moment and read a short story. This is the story of Billy. Billy was just an average guy with big dreams. Billy was interested in learning how to set up his own website. He got a domain something. So instead he sets up WordPress on a subdomain test. A few weeks go by and Billy is now happy with his website. Ready to take the world by storm, Billy copies his WordPress installation over to something. Not so fast. To keep your WordPress website safe, you need to constantly update the core as well as all the plugins you use. But Billy forgot about the instance of wordpress still running on test. And the rest is history. Because of one small mistake, the hacker gained access to the server and wiped away everything. The moral of the story is that all a hacker needs is one tiny oversight, the smallest of security holes, and a system is rendered defenseless. This is what makes theHarvester useful. The reconnaissance stage of hacking is devoted to following this trail of breadcrumbs that lead to a vulnerability. Information is our best weapon. Information about a target can mean the difference between quickly exploiting a system and a long and fruitless hacking attempt. For example, it could give us the private email addresses of a company. I recommend you play around with theHarvester, try out all the options, look up your favorite websites and see what you find.
Information Gathering with theHarvester
Another interesting tool for gathering informations, which can be used in combination with Recon-ngis theHarvester. Even if this tool is not as complex as Recon-ng, it helps to harvest a huge quantity of data in an automated way by using web search engines and social networks. By doing so, this information gathering suite allows to understand target footprints on the Internet, so it is useful to know what an attacker can see on the web about a certain company. If you are using Kali Linux, theHarvester is already a part of your arsenal. Another possibility is launching it by simply opening the Terminal and typing theharvester. In any case, we are prompted with the tool banner, version, author informations and usage instructions:. The instructions are pretty clear: we have a series of parameters to set as arguments through which we can customize the search. Some data sources require an API key to work: while the acquisition of some of them is free, like the Bing one, other require the payment of a fee, like the Shodan one. As reported above, the tool has quickly found emails, hostnames and has also resolved IP addresses. Another interesting feature is the capability to check for virtual hosts: through DNS resolution, the tool verifies if a certain IP address is associated with multiple hostnames. This is a really important information because the Security for a given host on that IP depends not only on its Security level, but also from how securely are configured the others hosted on that same IP. In fact, if an attacker comprimises one of them and gains access to the underlying server, then he can easily reach every other virtual host. It is ok to have results printed on the terminal standard output, but when we are dealing with a big amount of data it is nice to report them in a file for later use. Before launching the command, it is always a good practice to create a folder where we can store gathered data about the target:. Finally we can open the HTML file with our favourite web browser:. As shown in the above image, we get a nice graph reporting the percentage of gathered data for each category part of our search: emails, hosts and virtual hosts. After that we just get a list of all the elements for each category only a few lines are displayed here. Remember that you need to verify informations: for example, it could be that an employer is not working anymore on a certain company, but his email address is still present on the web and so it will be returned in the results. Automatic tools are useful, but still their outputs need to be correctly managed and interpreted. Installation If you are using Kali Linux, theHarvester is already a part of your arsenal.

Is a really simple tool, but very effective for the early stages of a penetration test or just to know the visibility of your company in the Internet. Since theHarvester makes use of third party information sources, some of these require you to have API keys to work.
