How to use the harvester
The harvester tool is really easy to use and its syntax of commands is pretty easy too.
Open the terminal and get the harvester’s help to have a look at all commands.
You can gather emails from various sources like google, bing, shodan, etc.
Now, let’s start playing with this tool.
Open a terminal and use the below command. We will be using github.com for our tutorial.
theHarvester -d github.com -b google -l 300
-d :- This option is used to specify the domain name of the target.
-b :- Specify sources you want to use for email scraping.
-l :- Limit of pages to explore. I am gonna go through only 300 pages.
The output will look like this. Found 1 email.
Exporting the output in HTML file
You can export the output of your results in XML or HTML file. Let’s see how to export the results in an HTML file.
theHarvester -d github.com -b google.com -l 400 -f /home/naruto/Desktop/emails-github.html
-f :- It’s used to specify the filename and path where you want to export the result.
-b :- Using the Baidu search engine for gathering emails.
Although there are some problems with this tool because, in the output file, it shows that only 1 email was found. But when I checked results in the exported output HTML file. I found lots of email addresses.
You can use the harvester to gather the email addresses of your target while doing reconnaissance. I recommend you not to depend too much on this automated tool. You should also try google dorks which is a really good manual way to gather emails of your target.
