[i] Description: An OSINT tool to find contacts in order to report security vulnerabilities.
[i] Usage: ./contact.sh [Options] use -d for hostnames (-d example.com), -c for vendor name (-c example), and -f for a list of hostnames in a file (-f domains.txt) 
[i] Example: ./contact.sh -d google.com -c google

Use the -d flag when trying to find addresses linked to a domain. contact.sh will return a “Confidence level” based on the source of the information retrieved. A security.txt file located on the domain will have a higher priority than a Twitter account on the company’s website.

$ ./contact.sh -d google.com

The -c flag allows you to specify the company’s name.

$ ./contact.sh -c google

If the company’s name contains spaces, make sure to place the name inside quotes.

$ ./contact.sh -c "keeper security"

You can check a list of domains using the -f flag.

$ ./contact.sh -f domains.txt

For the best results, combine both flags as follows:

$ ./contact.sh -d google.com -c google

contact.sh abides by the target’s robots.txt file.

$ ./contact.sh -d linkedin.com
