Almost everything in a refinery can be reduced to “basically a heater”. These refineries aren’t operated on internet connected networks, they do have local networks, but there is extremely strict IT at all of these plants. A lot of the plants are so old they don’t even have that, just electric wires running a 4-20 Milliamp signal from a DCS control room. It would require more than just a network bug.
Source: I work in refinery sales and am in them every single day, including Valero plants.
I’m just saying we shouldn’t speculate about this being some form of attack.
What happened? I just woke up and was prepared for all my stop loss to get triggered. Got notifications and checked, it turns out to be my take profits??? Is it a bug?
