Detecting that we have been hacked is not all that easy depending on the type of breach it is.

We have breaches that are easy to detect and those that are not.

The easiest breach to detect is an Overt breach. These are breaches where the hacker announces their presence like in ransomware, or one in which the hacker’s activity prevent us access to our system or online account or defaces our website.

The most difficult breach to detect is Covert breaches. These are those kinds of breaches where the attacker doesn’t announce their presence. It is left for the device or account owner to discover such a breach through the breach symptoms.

Important Point to Note Before You Continue Reading

In this post, we will focus more on symptoms that will help us detect covert breaches. But before that, there are some vital points I will like us to note.

Always remember that there are bogus overt breaches out there. Sometimes you will receive a fake ransomware or malware attack alert on your device.

In such times, you will see a bogus pop-up on your system, phone, or a website you visit requesting you to click on a link, pay a ransom or download an antivirus because your system or phone is under a ransomware attack, infected with malware, or has been hacked.

Whenever you see such an alert instead of reacting to it, it is advisable you contact a cybersecurity expert.

Another thing you should note is that most of the symptoms we will be used to detect covert breaches are not always a guarantee that your system is under an attack. There are some exceptions. Sometimes you might be experiencing some of the symptoms due to a new application you downloaded or an update you made or a hardware malfunction. Always remember this as you read.

How to Detect Covert Breaches

Covert breaches are the most difficult kind of breach to detect. Observation is the key to detecting these kinds of breaches.

It takes a person who understands the sound of his car engine when it is in its healthy state to detect the fault in it when the sound changes.

In the same way, it takes someone who understands the state and performance of his or her system, phone, or website to detect when things go amiss.

If you don’t observe well the state of your system performance, firewall settings, or application settings when things are in place, it will be difficult for you to notice symptoms of breaches when they occur.

So, observation is the key. Always take note of the state of things on your device or networks when nothing is amiss.
