About this interactive

What you are doing: naming which part of a malware sample each clause describes. The lesson’s four parts: the vector is how it gets into the organization — an attachment, a link, removable media. The payload is its intent, what it actually does — encrypt, steal, deny service, show ads. Concealment is how it stays hidden — running fileless, hooking the kernel as a rootkit, loading from the boot sector, packing its code. Command and control is how the attacker reaches it after it lands — beaconing out for orders. A word to watch: the lesson’s video calls the hiding part “the dropper”. A dropper is the component that installs the payload on the machine; concealment is what keeps it hidden. This activity uses concealment for the hiding. How to use it: ask which question the clause answers. How did it arrive? Vector. What does it do? Payload. How does it avoid being seen? Concealment. How does the attacker steer it? Command and control.
