Wireshark is a powerful tool for analyzing network traffic and protocols. With the help of Wireshark, you can capture network traffic and search within the captured traffic. Wireshark’s great features and ease of use make it one of the most popular network traffic analysis tools among network and security professionals. In this article, we try to teach you How to Use Wireshark in Nmap. It should note that you can visit the packages available in Eldernode if you want to buy a VPS server.
As in the previous steps, you can type the following NMAP command for TCP scan as well as start Wireshark on another hand to capture the sent Packet: nmap -sN -p 22 192.168.1.102. By executing the above command, you will see that port 22 is open. As you can see in the image below: 1. No Avast has nothing to do with this, just take a look to the another post which I created at the bottom of this post, the only way is that you always run the WireShark in Admin, and you actually can't give an app a full permission due to the security reasons, so you need to open it every time as Admin, just take a look the post which I created a shortcut for the wire shark via Apple Script.
Tutorial Use Wireshark in Nmap step by step
In the rest of this article, we’re going to teach you how to capture a network packet using Wireshark when an attacker scans the target using the NMAP port scanning method. In this tutorial, you will also learn how Wireshark records different packets of network traffic for open and closed ports. So we ask you to join us in this article with How to Use Wireshark in Nmap tutorial.

Use Wireshark in Nmap
The important point to note in this section is that in this section, work is done with the IP address (192.168.1.102). This is common for Windows and Linux devices. So you can distinguish them by your MAC address. In the following, we will introduce you to the different sections on how to use Wireshark in Nmap. Please join us.
How TCP Scan works
TCP Scan scans the TCP port like ports 21, 22, 23, 445. It should note that this scan ensures listening to the (open) port via a three-way manual connection between the source port and the destination port. After doing this, if the port is open, the source requests with the SYN packet, sends the SYN response destination, the ACK packet, and then the ACK packet source. Finally, the source again sent RST, ACK packets.
You can type the NMAP command to scan TCP as shown below. Also start the Wireshark on the other side to get the package:
As you can see in the image below, executing the above command indicates that port 445 is open.
At this point, you can look over the sequence of packet transfer between source and destination captured through Wireshark.
1. Source sent SYN packet to the destination
2. Destination sent SYN, ACK to source
3. Source sent ACK packet to the destination
4. Source again sent RST, ACK to destination
At this point, you can check the network traffic for the close port. If the scan port is closed, then a 3-way handshake connection would not be possible between source and destination. The source sends the Syn Pack, and if the port is closed, the receiver sends a response via RST, ACK.
You can use the following command for TCP scan as well as start Wireshark on another hand to capture the sent Packet:
As you can see in the image below, port 3389 is closed.
Now here you can Look over the sequence of packet transfer between source and destination captured through Wireshark.
How Stealth Scan works
SYN Scan is one of the most popular scans. This type of scan can be done easily and quickly and scans thousands of ports every second. It is also relatively typical and stealthy since it never completes TCP connections. Note that the port is also open if an SYN packet (without ACK flag) is received in response. Note that this scan is referred to as half-open scanning because you do not open the full TCP connection.
Like the following command, you can scan the NMAP instruction for TCP. You can also start Wireshark on the other side to record the packet sent:
By executing the above command, you will see that port 22 is open.

In the image below you can see a sequence of packet transfers between source and destination taken via Wireshark.
1. Source sent SYN packets to the destination
2. Destination sent SYN, ACK packets to the source
3. Source sent RST packets to the destination
Now you need to scan the NMAP instruction using the following command for TCP. Note that you must start the Wireshark on the other side to record the packet sent.
As you can see in the image below, port 3389 is closed.
You will see the following image carefully:
1. Source sent SYN packets to the destination
2. Destination sent RST, ACK packets to the destination
How Fin Scan works
In this section, we will introduce the FIN packet. Note that the FIN packet is using to terminate the TCP connection between the source and destination ports after the complete data transfer. How to do this type of scan is as follows:
In the place of an SYN packet, Nmap starts a FIN scan by using a FIN packet.
If the port is open then no response will come from the destination port when the FIN packet is sent through source port.
Note: Fin-Scan is only workable in Linux machines and does not work on the latest version of windows.
As in the previous steps, you can type the following NMAP command for TCP scan as well as start Wireshark on another hand to capture the sent Packet:
You will see that port 22 is open.
As you can see in the image below:
1. Source sent FIN packets to the destination
2. Destination sent no reply to the source
Scan the following instructions for TCP again and start Wireshark to record the packet sent:
As you can see, port 3389 is closed.
Looking at the sequence of packet transfers between the source and destination received via Wireshark, you will see that:
1. Source sent SYN packets to the destination
2. Destination sent RST packets to the destination
How Null Scan works
In this section, we are going to explain the Null Scan to you. A Null Scan is a series of TCP packets which hold a sequence number of “zeros” (0000000). Since there is no flag in this type of scan, the destination does not know how to respond to the request. For this reason, it destroys this packet and does not send any response indicating that the port is open.
Note: Null scan only works on Linux devices and does not work on the latest version of Windows.
As in the previous steps, you can type the following NMAP command for TCP scan as well as start Wireshark on another hand to capture the sent Packet:
By executing the above command, you will see that port 22 is open.
As you can see in the image below:
1. Source sent Null packets to the destination
2. Destination sent no reply to the source
Scan the following instructions for TCP again and start Wireshark to record the packet sent:
As you can see, port 3389 is closed.
Looking at the sequence of packet transfers between the source and destination received via Wireshark, you will see that:
1. Source sent Null (none) packets to the destination
2. Destination sent RST, ACK to source
Conclusion
Wireshark is the name of an Internet analytics tool formerly called Ethereal. This software analyzes the packets that are sent and received via the Internet and displays them to the user. Wireshark has many capabilities and you can use it to check packages sent and received on the Internet. In this article, we tried to teach you to step by step how to Use Wireshark in Nmap by giving an example.
Wireshark can’t make sense of encrypted traffic which is why we should also make sure sensitive traffic is encrypted. Wait.. wait.. there is one way to view encrypted traffic in Wireshark. If the attack was able to acquire the private key file, he or she could easily decrypted the TCP streams, reassemble and view the decrypted segments. How? It’s just a matter of pressing Shift + Ctrl + p, scrolling down to SSL in the protocol list and browsing to the stolen private key file. Scary but true.
Anyone can do this. It isn’t rocket science.
But it’s worse than that. Since most people aren’t encrypting their traffic these days, it’s super easy to see exactly what files are being downloaded by users.
You can see what videos people are watching. What images people are downloading and what songs people are streaming. It’s all in the capture and I’m about to show you how easy it is to do this.
Before we get started I want to warn you that you shouldn’t use this for illicit purposes. The reason I’m showing you how to do this is because I’m trusting you’ll use the informatoin I share to fortify your network and implement the correct controls to strengthen it. Under no circumstances am I espousing Blackhat hacking. By continuing to read you’re promising me you won’t use this to violate the privacy of your peers. Remember, don’t do anything to anyone that you wouldn’t want them to do to you.
Yes I’m loading you up with guilt to prevent your own ruin. I hope it worked.
This is by far going to be one of the most interesting articles you read all week. Why? Because I”m going to show you how to:
- See the images a person downloaded
- See the video a user streamed
- See the password a user typed
- See encrypted traffic on Wireshark
Yup, we’re going to break encryption. Get ready to rumble dood because this article is about to kick your ass. Let’s go!
Before we start spying on downloaded traffic we need to setup a few things in Wireshark.
First things first
First capture the traffic, then find your HTTP traffic, right click one instance, go to Protocol Preferences and make the following are checked:
- Reassemble HTTP headers spanning multiple TCP segments
- Reassemble HTTP bodies spanning multiple TCP segments
- Reassemble chunked transfer-coded bodies
Wireshark 10.9 Windows 10
Then right click a TCP segment, go to Protocol Preferences and choose Allow subdissector to reassemble TCP streams.
Once you’ve got that you’re ready to bang.
Seeing the images a user downloaded
Seeing what a user downloaded is easier than easy.
Load the packet capture, choose File, go to Export Objects and choose HTTP.
Now we’ll see all the HTTP objects. All of them for the session.
All CSS scripts. All Javascript files. All HTTP documents. But also all images.
Watch this.
If you sort by the Content Type column you can quickly identify all the image/jpeg files.
Clicking it makes Wireshark skip to the packet number in the output. In the HTTP object list dialog box, you can see the file name is taylor-swift_416x416.jpg.
But what if you actually wanted to see that image? Can you do that in Wireshark? After all just because someone downloaded a picture of Taylor Swift doesn’t mean they didn’t anything wrong.
To view the image, click Save As in the HTTP object list.
Save the file to your Desktop and double click it to what the user downloaded.
BAM!
It’s seriously that easy. Scary but true again.
If you wanted to find out the exact user who downloaded this file just open the Ethernet Frame and look at the MAC address.
You can see a user with MAC address 52:54:00:12:35:02 downloaded the image.
Now on the Cisco switch just type:
All you need are the last four digits of the MAC. It’ll tell you the switchport the user is physically connected to so you can hunt down that person and have an awkward conversation.
Pew… crazy stuff.
Alright I can’t believe I just shared that with you. Let’s keep going. It get’s worse.
See what videos a user was streaming
You can do the same trick with video. Viewing Youtube video streams in Wireshark is a little complicated though because Google no longer relies on .FLV files for Youtube. HTML5 is the new standard and thus is a bit harder to reassemble. But that doesn’t mean you can’t capture any video traffic.
Wireshark 10.9 Download
For example, look at what happen when I kicked open a video at watchop.com. You can actually see the video filename
op689ut.mp4 and the type of content which is video/mp4
Now I can save it to my computer as a .MP4 and kick it open in VLC Player.
Ouch!
Wireshark 1.9
The Bottom Line
Wireshark is a truth teller. It’s the serum that reveals the facts. The network doesn’t like and Wireshark can peer into all the details without any problems.
In the next part of this eye opening series on capturing packets I’m not only going to show you how easy it is to capture passwords but also view encrypted traffic.
Yup, we’re about to do the impossible. Check back tomorrow.
