How to Use ?
Searching emails accounts for the domain microsoft.com, it will work with the first 500 google results:
#./theharvester.py -d microsoft.com -l 500 -b google
Searching emails accounts for the domain microsoft.com in a PGP server, here it’s not necessary to specify the limit.
#./theharvester.py -d microsoft.com -b pgp
Searching for user names that works in the company microsoft, we use google as search engine, so we need to specify the limit of results we want to use:
#./theharvester.py -d microsoft.com -l 200 -b linkedin
Searching in all sources at the same time, with a limit of 200 results:
# ./theHarvester.py -d microsoft.com -l 200 -b all
