Tools: honeypot-setup-script

A script to install and deploy a honeypot automatically and without user interaction.

Currently installs and sets up:
  • kippo
  • dionaea
  • p0f
These will all be installed as system services so running this script once should turn a vanilla install in to a robust honeypot. Aims to use useful and secure defaults.
Currently tested on Ubuntu 12.04
Use with caution: This script will happily and without prompt overwrite files, change the port your SSH server runs and all sorts. It is intended to be run on a vanilla install of Ubuntu 12.04. No thoughts have been made for the integrity of existing installations of softwar - so be careful!

Howto: Install Snort + Barnyard2 on Ubuntu 14.04

1. Install Snort
# apt-get install snort
1.1 Config snort output unified to
output unified2: filename snort.log, limit 128

2. Install Required package for Barnyard2
# apt-get install autoconf libtool libpcap-dev libmysqlclient-dev libdaq-dev libdnet-dev build-essential git


3.  Download Barnyard2
# git clone git clone git://github.com/firnsy/barnyard2.git

4. Create Configuration Compile File
# ./autogen.sh

5. Install libdumpnet-dev
# apt-get install libdumpnet-dev
# ln -s /usr/include/dumbnet.h /usr/include/dnet.h

6. Compile Barnyard2
# make
# make install

7. Create configuration barnyard2.conf
cat > /etc/snort/barnyard2.conf << EOF
config reference_file: /etc/snort/reference.config
config classification_file: /etc/snort/classification.config
config gen_file: /etc/snort/gen-msg.map
config sid_file: /etc/snort/sid-msg.map
config logdir: /var/log/snort
config hostname: yourhostname
config interface: eth0
config daemon
config waldo_file: /var/log/snort/barnyard2.waldo
input unified2
output database: log, mysql, user=userofdb password=pwdofuser dbname=snort host=127.0.0.1
# to forward alerts also to syslog, uncomment the following 2 lines:
# output alert_syslog_full: sensor_name snortIds1-eth1, local
# output log_syslog_full: sensor_name snortIds1-eth1, local, log_priority LOG_CRIT
EOF

8. Copy scheme of barnyard2 that used in mysql
# cp schemas/create_mysql /usr/src/

9. Create directory log of Barnyard2
# mkdir /var/log/barnyard2

10.  Setup mysql# apt-get install mysql-server
# mysql -u root -p
mysql > create database snort;
mysql > create database archive;
mysql > grant usage on snort.* to snort@localhost;
mysql > grant usage on archive.* to snort@localhost;
mysql > set password for snort@localhost=PASSWORD('password');
mysql > grant all privileges on snort.* to snort@localhost;
mysql > grant all privileges on archive.* to snort@localhost;
mysql > flush privileges;
mysql > exit

11. Create structure
# mysql -u snort -p
mysql> use snort;
mysql> source /usr/src/create_mysql;
mysql> show tables;
mysql> exit

12. Fix "ERROR: Unable to open SID file '/etc/snort/sid-msg.map' (No such file or directory)" problem
# cd /usr/share/oinkmaster/
#  bash -c "sudo ./create-sidmap.pl /etc/snort/rules > /etc/snort/sid-msg.map"

13. Test run barnyard2
# /usr/local/bin/barnyard2 -c /etc/snort/barnyard2.conf -d /var/log/snort -w /var/log/barnyard2/test.log -C /etc/snort/classification.config./

15. Create startup script for barnyard2
#!/bin/sh

case $1 in
    start)
        echo "Starting Barnyard2"
        sudo bash -c "barnyard2 -c /etc/snort/barnyard2.conf -d /var/log/snort -f snort.log -w /var/log/snort/barnyard2.waldo"
        echo 'Barnyard2 started.'
    ;;
    stop)
        echo "Stopping Barnyard2"
        sudo killall barnyard2
        echo 'Barnyard2 stopped.'
    ;;
    restart)
        $0 stop
        sleep 4
        $0 start
    ;;
    *)
        echo "usage: $0 (start|stop|restart)"
    ;;
esac

exit 0

16. Change permission

CheatSheet: SSL Manual

http://www.exploresecurity.com/wp-content/uploads/custom/SSL_manual_cheatsheet.html

This table accompanies the presentation referenced here. It lists various SSL/TLS checks that can be performed manually with OpenSSL or a browser. Sometimes the column "insecure result" doesn't actually refer to an insecure configuration (for example, it may be a nice-to-have) but this should be clear from the context of the issue or the comments.

Tools: Incident Response Malware Analysis: IRMA

IRMA intends to be an open-source platform designed to help identifying and analyzing malicious files. However, today’s defense is not only about learning about a file, but it is also getting a fine overview of the incident you dealt with: where / when a malicious file has been seen, who submitted a hash, where a hash has been noticed, which anti-virus detects it, …
An important value with IRMA comes from you keep control over where goes / who gets your data. Once you install IRMA on your network, your data stays on your network.

File Analysis Process

  1. An analysis begins when a user uploads files to the Frontend.
  2. Frontend checks for existing files and results in mongodb. If needed,
    it stores the new files and calls asynchronously scan jobs on Brain.
  3. Brain worker sends as much subtasks to Probe(s) as needed.
  4. Probe workers process their jobs and send back results to Brain.
  5. Brain sends results to Frontend.
