The default position for any business is that it will fail. It can only succeed by a multitude of coordinated factors; disruption of any combination of these factors can seriously impact the business, drive down revenue, increase costs, and bring it to collapse.
There is no reason to assume that this must mean the use of violence. If you study the system upon which the company depends, and think creatively, you will find an almost unlimited number of ways, perhaps very simple ways, that you can damage their profitability. Research, for instance, various problems companies face that cause loss and inconvenience, that cause operations to be interrupted, etc. Perhaps a broken water pipe that floods the office; perhaps loss of paperwork; perhaps computer viruses; perhaps damage to delivery vehicles; perhaps to malfunctioning refrigeration at a warehouse, etc etc.
Break out of assumptions about how to fight. It does not only and always have to mean explosions and killing. As I have said, simply by letting a company understand that it is being targeted is a way to damage it. It is not important how you inflict loss and increase cost; just make sure that they can not profit.
