How do you handle hacking a corp? We want to access a Jinteki server, specifically something that's less protected (we're trying to find out about shipments of food and supplies to their facilities). How do you handle this as a whole? Specifically, how can this be done without being impossible or just full of killer sentries or whatever?

Just make up a new company and call it a subsidiary of Jinteki.

E.g. They need to target Growing Future a subsidiary of Jinteki that handles nutritional deliveries for Jinteki.
