I am using college network to access internet. Many other users are using the same network. Recently I have been experiencing sluggish net connection. So when I did some investigation, I found that many other computers on the network have been sending ICMP packets to me. I used Wireshark to analyse the incoming packets . Here is an screenshot of my my analysis:
(My IP was 192.168.38.58)
The packet capture was filled with these ICMP request. When I searched the web about it then I found that there is an attack named smurf attack in which attacker force other system in the network to send ICMP request to victim system.
Is this an example of smurf attack? If so then how to prevent my computer from being Attacked.
Please provide solution for both linux and windows Operating system.
EDIT No. 1:------
When I changed the MAC address of my PC, everything got back to normal. No such malicious packets were observed.
EDIT No. 2:------
I had used Advanced Port Scanner to scan my active port.
The port which was sending UDP packet(53411) is closed
