HoneyBadger

project goals

• HoneyBadger is primarily a comprehensive TCP stream analysis tool for detecting and recording TCP injection attacks.
• This git repository also includes a variety of prototype TCP stream injections attacks.

details

• Read about HoneyBadger's design and implementation: https://honeybadger.readthedocs.org/
• Read the manual integration procedure - a reproduciable procedure which proves HoneyBadger's TCP injection attack detection is reliable; in less than 2 minutes you can perform a test on your loopback interface... and test that HoneyBadger can detect injected data into a netcat client-server connection.

• Read the godoc autogenerated API documentation

• HoneyBadger currently support 3 Data AcQuisition packet sources: libpcap, AF_PACKET and BSD_BPF.

This means that for instance on OpenBSD, you must use the BSD_BPF DAQ by specifying this CLI option:

"-daq=BSD_BPF"

HoneyBadger attack detecton CLI examples!

Build honeyBadger CLI command from source:

user@go-dev2:~/gopath/src/github.com/david415/HoneyBadger/cmd/honeyBadger$ go build

Run honeyBadger against a pcap file called tshark2.pcap:

user@go-dev2:~/gopath/src/github.com/david415/HoneyBadger/cmd/honeyBadger$ ./honeyBadger \
-max_concurrent_connections=1000 -max_pcap_log_size=100 -max_pcap_rotations=10 -max_ring_packets=40 \
-metadata_attack_log=false -total_max_buffer=1000 -connection_max_buffer=100 -archive_dir=./archive \
-log_packets -l=./incoming -pcapfile=./tshark2.pcap

honeyBadger will spew lots of things to stdout. Using the above command, it will record an attack report JSON file(s) to the "./archive" directory. Here's an example output with a pcap file containing an ordered coalesce injection:

Or instead you can tell honeyBadger to analyze the wire with Linux's AF_PACKET capture mode. You should first disable offloading:

sudo apt-get install ethtool
sudo ethtool -K eth0 gso off
sudo ethtool -K eth0 tso off
sudo ethtool -K eth0 gro off

And then run honeyBadger like this:

./honeyBadger -max_concurrent_connections=1000 -max_pcap_log_size=100 -max_pcap_rotations=10 \
-max_ring_packets=40 -metadata_attack_log=false -total_max_buffer=1000 -connection_max_buffer=100 \
-archive_dir=/home/user/gopath/src/github.com/david415/HoneyBadger/cmd/honeyBadger/archive -log_packets \
-l=/home/user/gopath/src/github.com/david415/HoneyBadger/cmd/honeyBadger/incoming -log_packets=true \
-i=eth0 -daq=AF_PACKET

Linux security note

If running on Linux you can avoid running as root by using the setcap command. In Linux you can run packet capture tools as an unprivileged user after you run setcap as root like this:

# setcap cap_net_raw,cap_net_admin=eip honeyBadger

BSD security note

When using the BSD_BPF sniffer, avoid running as root by making sure your user has read-write access to /dev/bpf* If you are in the wheel group and the bpf devices are group owned by wheel then this should work:

# chmod g+rw /dev/bpf*
