Explanation

Backdoor malware is a type of Trojan that allows attackers to gain remote access to a system by negating normal authentication procedures. Backdoor attacks let attackers gain control of system resources, perform network reconnaissance, and install different types of malwares. Backdoors can be installed in both software and hardware. There have been many high-profile backdoor attacks in recent years, including the SolarWinds attack in 2020, which was suspected to be carried out by nation-state actors. Backdoor attacks can be prevented by using strong passwords, keeping software up to date, and using security software.
