With that kind of WHut insider connection, it wouldn’t be too far-fetched to have Xerox or Adobe programmers “update” their software to behave in the far-fetched manner required within limited circumstances. Someone needs have archived the software extant at the time of the original scan for the ostensibly-generating machine. At this point I wouldn’t trust company repository driver software not to have been similarly corrupted and back-dated. Such machines may automatically update their software via the Internet or via periodic company service packs, obliterating earlier software in those cases.
At least catching them in the fashion suggested by above would be as worthy as any Columbo episode!

That would make more sense than hacking individual machines. Anybody with programming knowledge know how a person would detect such a scheme if it happened?
