What best describes a Trojan Horse in the context of cybersecurity?

A Trojan Horse in the context of cybersecurity is best described as an attack tool disguised as legitimate software. This malicious software appears to be harmless or beneficial to manipulate users into installing it on their devices. Once installed, it can perform a range of harmful actions without the user’s knowledge, such as stealing data, creating backdoors for attackers, or enabling remote access to the system.

Unlike self-replicating software, which spreads on its own, or tools that automatically propagate across networks, a Trojan relies on tricking users into running it under the guise of something they find useful or trustworthy. Understanding this concept is crucial because it highlights the importance of user vigilance when downloading and installing software, regardless of how legitimate it may seem at first glance.
