Volatility: Analysis 'vmem' memory ----write up of 'fi02' in Cyber FastTrack

Problem: analysis memory file. To find the content writing on the screen of the notepad.

Hint: the strings has ended with y, and the  character contains an extra 'y'. Don't submit two 'y' s

Tools: Volatility

Solution: 

Step 1: Selecting a Profile

First, we can check the information of this memory file.


$ vol.py -f memory-image.vmem imageinfo 


The profile of this computer is Win7SP1x64.

Step 2: Viewing Running Processes

The notepad was writing so that this process should be on the background. 


$vol.py -f memory-image.vmem --profile=Win7SP1x64 cmdline 


we successfully found the pid of the notepad process which is '2740'.

Step 3: Get the memory of notepad's process.

Dump extracted '2740.dmp' to get the addressable memory of the process. 


$vol.py -f memory-image.vmem --profile=Win7SP1x64 -p 2740 memdump --dump-dir .


Step 4: Find the strings 

Because the strings ended with a 'y' and contains an extra 'y', then we were going to use grep 'yy$' to find the strings. First I didn't get the strings I want, then I guess it may be little-endian, so I added '-e l' in the command.


$strings -e l 2740.dmp | grep "yy$" 



Luckily, we found the flag!

 flag:noting_notes_in_a_noting_way

Other command:
find files in the image:

vol.py -f flounder-pc-memdump.elf --profile=Win7SP1x64 filescan|grep resume 

dump file in the image:


find pid tree in the image and output to memdump.dot:

vol.py -f flounder-pc-memdump.elf --profile=Win7SP1x64 psscan --output=dot --output-file=memdump.dot 

find cmd and service:

vol.py -f flounder-pc-memdump.elf --profile=Win7SP1x64 cmdline

 0x00 Problem  0x01 Check the vulnerability When we see the login form on the website, it might be command injection, SQL injection, LDAP injection.  We can see that this need us to login with workstation username, it might be LDAP injection. 0x02 LDAP injection payload Here is the basic LDAP injection payload. We can check the vulnerability. user=*)(& password=*)(& --> (&(user=*)(&)(password=*)(&))  After we type it, we found the response shows successful, and return a page has search box. Then we type a character in the search box, and it returns some user phonebook information. I tried 'flag', 'HTB', it doesn't find any results. Then we try to find user 'Reese', but the information doesn't look like flag.   0x03 Locate the flag  Then we change our payload to check if the password is the flag. user=Reese password=HTB*)(& --> (&(user=Reese)(password=HTB*)(&  It can also return to the search page which means it...

wafwaf -- Hack The Box -- Web SQL injection

0x00 Problem 0x01 Check the Source Code We open the website and only see the source code on the website. As we can see, there is a WAF will filter some characters and words, that means the normal injection will not work. However, we can see, there is a json_decode() function will decode JSON data, that means the data can be accepted should be JSON format.  The example JSON format data is like: /u0074, /u0075. In addition, there is a "php://input",  accesses the read-only stream of the requested raw data, executing the data in the post request as PHP code. 0x02 Local Test We can launch an Apache server to test it. I copy the source code and make a little change to test this. This file is in /var/www/html. We will construct the data first. This time I use 'select' as an example. The word transfer to ASCII, then to hex, then replace the '\0x' as '\u00'. This can be test in the browser console. At the end, we can test it with curl . As we can see, the SQL...
