It seems this might be a much bigger problem...

 

Today, I was emailing with a reporter about my post on the North Carolina substation attacks, when I saw this article that had been linked in the Utility Dive newsletter (which I normally open as soon as it hits my inbox). It seems that NC might not have been an isolated incident after all. You should read the whole article, but IMHO the executive summary is these two paragraphs:

“Power companies in Oregon and Washington have reported physical attacks on substations using handtools, arson, firearms and metal chains possibly in response to an online call for attacks on critical infrastructure,” the memo states.

The aim, according to the memo, is “violent anti-government criminal activity.”

Another:

The department wrote that attackers would be unlikely to produce widespread, multistate outages without inside help. But its report cautioned that an attack could still do damage and cause injuries.

Of course, we’re not talking about multistate outages. A multi-day, multistate outage might be a catastrophe with loss of life, especially if there were a big city in one of those states (see Ted Koppel’s Lights Out, which very eloquently describes what would happen if there were a multistate outage that lasted more than a few days. What’s unfortunate is that Ted let someone persuade him that he should sell the book as being about the effects of a cyberattack on the grid, when exactly the same results would occur, no matter what the cause. The book is an easy read and still definitely worth it, years after it came out).

But an attack that could “do damage and cause injuries” is a good description of what just happened in NC. It certainly caused damage, and people were injured in car crashes, if for no other reason. We may hear later about people on oxygen at home, etc. that were victims as well. An extended power outage is always a big problem.

Finally:

The targets also present an increasing challenge to secure because attackers don’t always have to get as close as they did in North Carolina in order to do damage, Southers said. With the right rifle, skill and line of sight a sniper could take a shot from as far as 1,500 meters (about 4,900 feet) away.

That’s quite interesting. If line of sight is a problem (which it definitely was with the Metcalf attack), then that will require fairly big, expensive fences.

Unfortunately, as I told the reporter today, it will be impossible to prevent attacks like this without huge expenditures (unless there’s a good way to triage substations for degree of risk, which I’m not sure is the case here). One thing I suggested is that, since this is obviously a national problem, the feds should finally step in and pay for the mitigations themselves – rather than dump all the cost on the utilities and especially their ratepayers. This has been for the most part the practice so far, when it comes to both physical and cybersecurity, but it’s time to acknowledge this is a national problem.
