Trojan or Not? — TechKnowSurge

About this interactive

What you are doing: deciding whether each piece of malware is a Trojan. The lesson’s test: a Trojan is intended to mislead the victim. It looks like something legitimate, such as a program, a login screen, or a free tool, so the user installs it or types into it, and then it compromises the system or captures what they enter. Like the horse the city of Troy accepted as a gift, the danger is let in on purpose. How to use it: ask how it got in. If the victim accepted it because it pretended to be something real, it is a Trojan. If it spread on its own, rode inside an infected file, or came through an unpatched flaw with no disguise, it is not. A wrong answer resets your streak.

What you'll learn

Decide whether a piece of malware is a Trojan by its defining trait: it disguises itself as something legitimate so the victim lets it in
Explain that a Trojan is defined by deception, not by what it does once inside, and that code which spreads or attacks without a disguise is not a Trojan
