Managed switch or linksys router how the hell is it so easy to push that much money around even if I work in that "room" and give you access to my computer for a hour there should have been some software to notice somethings going on. The switch is could have been a $10,000 switch and it still sounds to easy. I'd say inside job unless scanning the up range screamed out the company name and some easy vulnerabilities/old software versions which could have also been the case.
