Top 1,000 TCP and UDP ports (nmap default) How To: Use mitmproxy to read and modify HTTPS traffic Iptables -t nat -A PREROUTING -i $nic -p tcp -dport 443 -j REDIRECT -to-port 33231Įnhance your filter offline cd /data/dumps/ We want a port that is not in nmap’s top 1000 to remain hidden. What Is mitmproxy mitmproxy is a command-line tool that acts as a HTTP and HTTPS proxy and records all the traffic. w /data/dumps/$date.mitmdump -flow-detail 0ĭefault port for mitmproxy is 8080 being used for both http or https. It provides a console interface that allows traffic flows to be inspected and edited on the fly. Same as above but with -ignore-hosts '^(?!+:)(?!(+\.)*example\.net:)' \ĭon’t ask me why we need an absolute path there mkdir -p /data/dumps/Įxport MITMPROXY_SSLKEYLOGFILE="/data/dumps/$" mitmproxy is an interactive man-in-the-middle proxy for HTTP and HTTPS. Now sniffing ONLY and passing through the rest with no tainting. –or– in tcpdump-alike style (writes to a file) TEXT / ON-THE-FLY MODE echo $LANG Start the mitm service either with a TUI (this truly eats your memory) Mitmproxy wants CRT + KEY concatenated as PEM file cat > Openssl req -x509 -newkey rsa:2048 -nodes \ Ideally you get a true cert but this makes a PoC cd ~/certs/ and add hosts entries pointing the desired domains at 127.0.0.1 like the suggestion in the docs. Let’s have a look on what you need to impersonate echo Q | openssl s_client -servername TARGET-VHOST -connect TARGET-HOST:443 \ There are two ways to go for ssl interceptionĮither as package, from scratch or using latest released binariesįrom scratch apt install python3 python3-venv You can run mitmproxy as user on a local and exotic port, as long as you enable the interception. on the client’s side, the right network path shows up but the first hop. In any case, making sure you have the appropriate gateway and resolvers yourself so you can relay the traffic. with the intent to redirect all traffic going to port 80 to my Linux machine on port 8080, the one mitmproxy listen to by default. I have two machines: One Linux machine on which I run MITMProxy One Android Embedded Device which traffic I want to redirect. SSL MITM WITH MITMPROXY SSL MITM WITH MITMPROXY INTROįirst of all, you need to be on the network path, be it as an existing gateway, by means of dns or arp spoofing, what-so-ever. I’m trying to use MITMproxy in Transparent mode.
