What is an exploit: understand how they explore your system

Exploit is a sequence of commands, data or a piece of software created by programmers to search for potential system vulnerabilities

Good digital security practices are basic to keep sensitive data and information away from cybercriminals. Do not click on links or do not open unknown files are frequent recommendations to avoid contamination by viruses or malware. But there is also a type of threat that does not require user action to scan vulnerabilities and system breaches. Do you know what is an exploit and how does it works?

Exploit is a sequence of commands, data or a piece of software created by programmers to search for potential system vulnerabilities. Cybercriminals use exploits to cause some unexpected behavior in a running software or hardware, gain take control of a system to elevate administration privileges and execute commands or even promote DoS attacks.

To spread, exploits don’t depend on user action. This is how they differentiate from viruses, that require a user to click on a particular link, download or execute some file to infect the system. For this reason, exploits are considered especially dangerous.

Typically, exploits are classified according to their way of communication with the vulnerable system: remote, if they work in a network and exploit security vulnerabilities without any prior access; or local, when they require prior access to the vulnerable system, increasing administration privileges. Other forms of classification consider the type of vulnerability exploited or the result of the infection.

In terms of security, one needs to use tools able to identify vulnerabilities and malicious codes, manage system permissions and configuration changes, create security rules, advanced intrusion protection features, anti-malware and more.
