Exploit development

Do you know how to recognise an exploit? These are programmes or codes designed to exploit a weakness in software and cause unwanted effects. But in order to best define them, we must first examine the vulnerability. Do you know the difference?

‍

Vulnerabilities are weaknesses or security holes in a system and/or network that can allow hacking by malicious attackers.

‍« If a vulnerability is the open window on the system, an exploit is the ladder the thief uses to reach it. »

‍

More simply, an exploit is a tool created to make use of a specific vulnerability: without a weakness, there is nothing to exploit. This does not mean that all flaws can be easily caught, as sometimes the nature of a particular vulnerability is such that hackers cannot figure out how to transcribe the code that exploits it.

But back to our analogy, not all open windows are perfect for thieves: sometimes they are too high to be reached, or they might only lead to a locked basement. The same concept applies to security holes in the system: cybercriminals cannot always exploit every window.

HOW TO RECOGNISE AN EXPLOIT ATTACK

Because exploits use software vulnerabilities, there are no clear signals that you can recognise: a user almost never has any way of knowing that he or she has been hit until it is too late. This is why it is important to always update the software and install the security patches released by the developer.

‍

Although you might not notice an exploit, once malware creeps in, you will definitely feel the effects. Look for the common signs of a malware infection:

‍

• slow performance;
• frequent crashes or freezes;
• inexplicably changed settings;
• recurring pop-ups or ads;
• loss of storage space.

‍

If you encounter any of these warning signs, you should immediately run an antivirus scan with a powerful and reliable tool.‍
