Discovery

Port scanning

ip="10.0.0.1" && for i in {20..25}; do echo > /dev/tcp/$ip/$i ; if [ $? -eq 0 ]; then echo -e "Port: \e[4m$i\e[0m is Open on host: $ip" ; fi ; done 2>/dev/null

Traceroute

# Without latency
h="google.se" && for i in {1..255}; do ping -t $i $h -c1 -n | grep From ; if [ $? -ne 0 ] ; then break ; fi ; done

# With latency (sends an additional package per hop)
h="google.se" && for ip in $(for i in {1..255}; do ping -t $i $h -c1 -n | grep From | awk '{print $2}'; if [ ${PIPESTATUS[1]} -ne 0 ] ; then break ; fi ; done) ; do ping -c1 $ip | grep from ; done

Shodan

jq -r 'select(.domains | any(. == "domain.tld")) | {domains, ip_str, product, port, number_vulns: (.vulns | length)}' data.json | jq -s 'sort_by(.port)'

Self signed cert

openssl req -x509 -newkey rsa:4096 -keyout ssl/key.pem -out ssl/cert.pem -sha256 -days 365 -subj "/C=US/ST=CA/O=MyOrg" -passout "pass:$(pwgen -N1 96 | tee ssl/pass.txt)"

HTTPS Server

import http.server
import ssl

lhost = "0.0.0.0"
lport = 443
server_address = (lhost, lport)
httpd = http.server.HTTPServer(server_address, http.server.SimpleHTTPRequestHandler)
httpd.socket = ssl.wrap_socket(httpd.socket, server_side=True, certfile="ssl/cert.pem", keyfile="ssl/key.pem", ssl_version=ssl.PROTOCOL_TLS)
httpd.serve_forever()
