Nurses make great serial killers, I can only assume they would make equally good political assassins!
So first you call for tech support, just any bullshit issue, but word it ambiguously so they have to talk to you to figure out what you meant. drop a comment to provoke a response, measure their opinion. Designate them target, nonentity, or potential comrade to recruit to the cause. Keep going until you find either a target you can turn to an asset until its time to dispose of them, or a comrade who might genuinely assist. IT get you the information from personnel records and department meetings. Boom. Linux on the whole system within a year, and you’re skimming license fees to build that concentration camp for landlords.
