I think a couple William Gibson novels start out this way: S.F. officials locked out of computer network
A disgruntled city computer engineer has virtually commandeered San Francisco’s new multimillion-dollar computer network, altering it to deny access to top administrators even as he sits in jail on $5 million bail, authorities said Monday.
This is likely the result of a failed management process rather than a technical vulnerability. In fact, the system must be pretty secure if they are still trying to get in!
With systems this large, you have to have audits and monitoring of everyone with significant access, including those doing the monitoring. Otherwise, stuff like this becomes possible.
Plus, this guy was a known problem for quite some time, apparently. Always make sure you’ve secured the network before trying to terminate the top system administrator.
