A parking-kiosk vendor plugs an unmanaged laptop into the city VLAN and wormable malware spreads. What introduced the attack?
Select an answer to reveal the explanation.
Short Explanation
The kiosk tech just docked a mystery laptop onto the city street. That unmanaged box is the front door—the worm did not need a parks website or a VPN spray to get in. Treat the vendor endpoint as the introduction vector.
Full Explanation
Connecting an unmanaged vendor laptop to a municipal VLAN is an untrusted-endpoint introduction path. Wormable malware then moves laterally from that host. A watering-hole, VPN password spray, or mailbox forwarding rule would leave different evidence and are not what this scenario describes.
