As we know from recent history, many companies have pursued criminal charges against people who have broken into their systems, even if they had no intention to do harm. And DAs are very happy to prosecute these cases. So this would be a great virus to write if you wanted to add a prison sentence to your resume. (And you could be held responsible for the cost of restoring the servers after your failed upgrades, which could run into the millions of dollars if you damaged enough servers.)
