What I found most intriguing was how it made use of three zero days that allowed it to go as long as it did without being detected; vulnerabilities that allowed it to infect 100′s of thousands of computers by using thumb-drives and local area networks. You would think it’d be such an ineffective approach with things like the web that allows you to mass compromised so many more.
