Meet “Roger.” A decade ago, he was managing a team designing electronic shop tools. The gig was getting stale, so Roger started looking for ways to spice up his workdays. Enter Nmap—the ultimate network mapping tool. On a slow Friday afternoon, Roger decided to poke around the company’s internal network. He got hooked. Curious about how the IT department structured the network for their mid-sized company—spanning engineering, sales, marketing, and a full factory—he hatched a plan. Why not launch a massive, weekend-long scan to see what turned up? He hit start, walked out, and enjoyed his weekend. Monday morning, Roger walked in to a double surprise. First, his laptop was gone. Second, the head of IT was marching toward him with a haunted, wild-eyed look. This was no social call. Roger asked about his missing machine. The IT boss dropped the bomb: both he and the COO had tried to VPN in over the weekend, but the entire network was completely fried. Their frantic troubleshooting led them straight to Roger's desk. The moment they unplugged his laptop, the network miraculously sprang back to life. Cue the interrogation. Roger played dumb. It wasn't hard—he genuinely didn't realize his weekend scan would nuke the company's bandwidth. Thinking fast, he mentioned a recent trip to the company’s China office and wondered aloud if he’d picked up a nasty piece of malware abroad. Hook, line, and sinker. IT threw the laptop straight into digital purgatory. For a full week, the tech team ran relentless virus scans, finding absolutely nothing. Confused but defeated, they returned the machine alongside a stern lecture about cybersecurity while traveling. Roger took his laptop back. And yes, Nmap was still installed.
