  • What is Hacking? 
  • Then how to understand whether our system is already hacked or not.

What is Hacking?

So let's begin with what is hacking? Hacking is an illegal act performed by a cyber criminal to steal data and information from the targeted system by breaking into the system security unknown to the user. The person who performs this task of breaking into the system is known as a hacker.

They apply illegal means to gain access into the targeted system by using network hacks, spam or malicious programs. 

How to know if our computer system is hacked?

Now that we understand what is hacking, let's take a look at some points to know whether our system is already hacked or not. 

The first point regarding how to check whether a system is hacked or not can be cases where the system security is switched off by unknown means and it is not visible to the user. This is one of the most primary checkpoint to know if our system is hacked or not. 

Next point to check whether a system is hacked or not would be frequent antivirus software failures which are due to the interference from hacking attempts performed by a professional hacker or a cyber criminal. 

Then we also face problems regarding systems reaction speed which is affected due to the execution of unknown applications in the background of the system which also affects the hardware resources in the device. 

Next we also face problems regarding passwords which are no longer working or are changed without the user's intervention which might indicate that there was some unknown hacking activity that took place in our account. 

Let's take a look at some more points regarding the topic. There are often cases when the system's cursor move on its own and perform tasks indicating that the system is being used by someone else using an illegal hacking method.

There are also cases when we often see files and folders being created in the storage disk on the system which is unknown to us. 

To better understand these points regarding how to identify whether our system is hacked or not let's take a look. 

Then let's start with the first point. If we want to check whether a system is hacked or not the first point would be to choose the settings option and using privacy and security and moving on to the window security. There's option that is available on our system allows us to see various protection applications that are available on the system. If we see any problem regarding any one of them for example apps and browser control in my system it says there's a problem with it which might be due to hacking attempts that was done on my system. 

Now let's take a look at the other option how we can check whether our system is hacked or not. That would be checking the antivirus software that is installed in our system. If you face problems regarding that, this might be the issue.

According to my antivirus software it says my computer is at risk this might be due to the interference from cyber criminal or a hacker while using different illegal softwares during its hacking attempt. 

Then there are also cases where we see there are unknown programs being executed in the background of our system which we can take a look using the task manager software. Using the task manager we can take a look at each and every application that is being executed in the system and see the origin. If we find any unknown program or application we can assume that it might be due to a hacking attempt. 

Moving on if we want to check further whether our system is hacked or not we can check for files or folders that are being created unknown to us for example, if i see unknown folder which contains some security details that are unknown to me, this might be also be due to a hacking attempt by a hacker or a cybercriminal. 

Then there are also cases when the system's cursor move on its own and performs tasks that are not initiated by us and performs copying of different folders or data from one file to other. This is due to a hacking attempt that was done on a system and the hacker has taken control of our system. Then there are also cases regarding login issues or password problem for example if I want to access into my account and there's a problem with the password it might be due to the attempt of hacking into my account by a professional hacker. Seems like there's a problem with the username which means there was a hacking attempt by a professional hacker. We can further check hacking attempts by accessing our web browser and checking whether there's some extra add-ons or unknown add-ons that wasn't installed by us. This might also indicate a hacking attempt on the system. 

Counter measures against hacking 

Now that we are clear about how to check whether a system is hacked or not let's take a look at some of the countermeasures against hacking. 

The first point regarding how to avoid hacking is do regular manual security checks and keep the system security updated. 

Using certified antivirus softwares is a basic countermeasure against hacking attempts and if possible visit only secure websites for surfing on the internet or use VPN or other internet security applications to mask your system's network to avoid any hacking attempts for the device. 

Then we have avoid clicking on random web pop-ups and ads to avoid hackers from getting into our system and accessing a device data.

Lastly, we use strong passwords or complex passwords for our login details. 

Conclusion 

Applying these countermeasures we can avoid hacking to a certain extent. With this we have reached the end of this post.
