A Trojan backdoor, also known as a Trojan backdoor virus, is a specific type of malware that combines the characteristics of a Trojan horse and a backdoor. It is a malicious software program that disguises itself as legitimate or desirable software or files while also creating a hidden entry point or backdoor within the targeted system.
When a user unknowingly installs or executes a Trojan backdoor, it typically appears as a benign or useful application. However, behind the scenes, the Trojan backdoor establishes a covert communication channel between the compromised system and the attacker's command and control server. This enables the attacker to gain unauthorized access to and control over the infected system remotely.
