A Trojan Horse is primarily known for which of the following characteristics?

A Trojan Horse is primarily known for its ability to trick users into installing it. This type of malicious software disguises itself as a legitimate application or file, leading users to believe they are interacting with something safe and useful. Once installed, it can execute harmful actions without the user's knowledge.

This characteristic is crucial because the effectiveness of a Trojan relies greatly on social engineering tactics. Users often inadvertently download and run the Trojan, believing it to be beneficial, which is why the focus is on deception and user manipulation. Understanding this aspect helps in identifying potential security risks and developing strategies to mitigate threats that exploit human behaviors.

While it is true that certain Trojans might offer features like unauthorized remote access or might be embedded deep within the operating system, their defining feature is the deceptive nature that leads users to willingly install them. This distinction sets Trojans apart from other types of malware, such as worms, which propagate independently without user intervention.
