#### Pull data from SSL

* data about which sites are protected can be in the SSL certificate

```shell-session
curl -s https://crt.sh/\?q\=inlanefreight.com\&output\=json | jq .
```

**Filter by subdomain**

```shell-session
curl -s https://crt.sh/\?q\=inlanefreight.com\&output\=json | jq . | grep name | cut -d":" -f2 | grep -v "CN=" | cut -d'"' -f2 | awk '{gsub(/\\n/,"\n");}1;' | sort -u
```

**Get ip address for above subdomains**

```
curl -s https://crt.sh/\?q\=inlanefreight.com\&output\=json | jq . | grep name | cut -d":" -f2 | grep -v "CN=" | cut -d'"' -f2 | awk '{gsub(/\\n/,"\n");}1;' | sort -u >> subdomainlist
```

```shell-session
for i in $(cat subdomainlist);do host $i | grep "has address" | grep inlanefreight.com | cut -d" " -f1,4;done
```

* can run shodan on the IP's
