A hospital in Somewhere, USA uses XYZ Software's Medical Manager suite. This application runs on a Windows based network. One of the internal databases is called $sys$PatientAllergies which keeps track of which patients are allergic to certain medicines. A patient, John Doe, is admitted for having potentially serious illness. Mr. Doe is highly allergic to medicine XXX and tells the nurse he could die if used on him. Sometime after the nurse enters this information into the Medical Manager, she plays her new copy of Sony's latest release with said DRM technology. A short while later Mr. Doe takes a turn for the worst becomes unconcious. Only two medicines can save him, medicine XXX and a less effective alternative. The doctor on hand checks the Medical Manager suite for any allergies Mr. Doe might have and sees that there are none because Sony's root kit has silently hidden Medical Manager's $sys$PatientAllergies database. Mr. Doe is given medicine XXX and dies within minutes.
