What characteristic defines a Trojan horse in cybersecurity?

The defining characteristic of a Trojan horse in cybersecurity is that it appears benign or harmless but actually contains harmful code or functionality. This deception often leads users to install the software, believing it to be something beneficial or safe. Once installed, a Trojan horse can execute malicious actions such as stealing personal information, allowing unauthorized access, or installing additional malicious software.

The nature of a Trojan horse is to disguise itself to evade detection, which is why it is crucial for users to be vigilant about the software they install, even if it seems legitimate. Understanding this characteristic helps to identify and protect against potential cybersecurity threats, emphasizing the importance of cautious behavior online.
