But there is an element of permission inherent in DHCP. Your device is actively configuring my device specifically to allow network access . It's not an open door; it's a sign saying "This way please". That said, its obvious this was an attempt to circumvent access controls.
You're right that (as alleged), this would be an obvious attempt to circumvent access controls.
Given the way things are worded, I'm guessing that the MIT computer that was improperly accessed was a router or switch. Hell, just plugging into the switch directly could be construed as unapproved access to a computer device. I think the Federal law treats anything with a processor a computer.
