I work in a horticultural production facility, where we propagate and stage thousands of varieties of ornamentals. Just like most modern production operations, our equipment is driven by PLC Programmable Logic Controllers. There are sensors that pick up on dozens of different parameters. The sensors send information to an I/O module, and translates a voltage reading into any number of different values. The info is then sent back to an access point and user PC software.

Whether you are producing food, toys, plants, or most anything, PLC and its software are the new norm. What I have learned becoming certified in this software, is that it is vulnerable to outside attack just like anything else. There are layers upon layers of alarms, security options, even audible alarms throughout the facility BEFORE a damaging event occurs. For example, if i program a setpoint temperature, and the computer predicts that the fluctuations will be too extreme, it will send out an alarm and SMS/email notifications.

The consensus here seems to be foul play, and I agree.
