You might not know but there is a possibility that somebody is stealing your data from your computer. In most of the cases virus, Trojans or spywares sends the data from your computer to remote computer without letting you know. Not only this is severe threat for your computer but it also shows that you’re dumb enough to be phished. In this post I’ve posted a simple tip to find out unauthorized activity on your computer.
To find out trespassing and unauthorized activity on your computer, follow these simple steps:
Open Command Prompt (Go to RUN, Type cmd)
Now type ‘netstat’ without quotes and hit Enter.
The command netstat (Network Statistics) is a command-line tool that displays network connections (both incoming and outgoing), routing tables, and a number of network interface statistics. It is available on Unix, Unix-like, and Windows NT-based operating systems.
Here, In the above picture you can see all the active connections and Foreign Address connected to my computer.
MAGIC-VAIO is my computer name so, I Ignored it saying hey! It’s not an unauthorized activity.
Next, some unknown kind of letters are written as ‘sjc-not17’. I googled the exact keyword and found that It is my local dropbox folder which is connected to Internet to synchronize my data.
Next is some IP address 188.8.131.52 and its state is FIN_WAIT_2, meaning I was connected to some server and now my computer has no data to send or receive. So, It is not a threat or unauthorized activity because if you open a webpage and after delivering the content the server to go to FIN_ state.
In next line, I found another random letter and again I googled the keywords ‘maa03s16-in-f3’ and found it is my ISP. Hence, it is also not an unauthorized activity.
So, you could see that how I was trying to analyse the outgoing traffic from my computer. You can also do that to find out if there is any unauthorized activity running in background of your computer. Let me know what you’ve got.
