Reversing malware, one of the foundations of cybersecurity

Malware attacks on institutions and individuals are multiplying. Cyber-attacks carried out by different types of hackers seeking various purposes (espionage, money, their own amusement, etc.).

Cyber risks are a reality in society and therefore it is necessary to know how to combat them.  

But first of all, do you have a clear picture of the the definition of malware? Before delving into malware reversing, one of the foundations of cybersecurity, it is necessary to have a good understanding of this term.

To begin with, what is malware in computing?

Because maybe you've heard of "malware" many times, but you don't know it for sure. Even if you do, it's never a bad thing to brush up on the concepts:

Malware or malicious software defines any type of computer code or programme, which is created ad hoc to damage, invade or control an electronic device, network or computer system.

That is to say that within the same malware we will not only find the famous computer virusesbut also other types such as Trojans, worms, malicious cookies and others.

It is worth noting that in order to find out how a particular malware works, it is necessary to keep in mind the type of operating systemWindows (the vast majority of malware is of this type), Linux... And, of course, mobile systems such as Android.

What is malware reversing, one of the foundations of cybersecurity?

So why do we say that malware reversing is one of the foundations of cybersecurity? Here is its definition:

Malware reversing encompasses the study of malicious code in order to know and identify the vulnerabilities used to infect a system, the attack vectors and the level of infection. All of this is done in order to create and implement protection measures.

In this way, Malware reversing has become one of the key methodologies in computer security.It can combat all types of malware whose origin is unknown.
And, although the modus operandi is similar to reverse engineering, these terms should not be confused.

What is the definition of reverse engineering?

Reversing malware, one of the foundations of cyber security, is not the same as reverse engineering. Although it is true that both are very new and effective techniques.

To begin with, reverse engineering is that branch of engineering which studies the performance of a productThe aim is to replicate it and thus to analyse and understand its possible failures.

So, in a way, Reversing malware is reverse-engineering when you reverse-engineer it.. Because malicious code is being studied in order to understand it and implement cybersecurity measures.

Sandbox in IT security: another concept to take into account

Another term to take into account in order to understand what malware reversing is, is the Sandbox in IT.

Sandboxes define a series of cybersecurity mechanisms that isolate malware-infected software from the rest of the system. All this, so that the malware does not spread throughout the system.

In this way, just like children's sandboxes, cybersecurity professionals develop these controlled environments. And you, are you interested in cybersecurity? Have you ever thought of going into IT security?

Are you interested in cybersecurity? At IMMUNE you can train in it.

Indeed, if you want to become a cybersecurity expert and implement measures such as malware reversing or follow IT philosophies like DevSecopsyou must have specialised training in computer security. The IMMUNE Institute of Technology can help you with this.
