Oof that spreadsheet story is like a glazier breaking windows, quite a way to make yourself indispensable! I had to bring in a forensic IT expert after terminating someone who twice claimed twice he "might know a way" to read folks' email with no traces in the logs. He had previously mentioned a deadman-switch type setup, but in more of a "wouldn't it be cool" way. After forensic person found no exploits, the recommendation was to proactively pay the employee a chunk of change with the stipulation that any future hacktivity would be treated as a criminal matter. We didn't do that (employee wasn't smart enough to create an invisible backdoor, or dumb enough to not just walk away). The bad decisions he made (hiring, vendors, boys' club culture) probably did more damage than malicious code, and it's taken about 2 years to undo it.
