ICS/DCS Control Systems Aren’t prepared for this. Still.

An ingeniously simple control systems experimental power grid hack attack from 2007. Source:


A protective relay attached to that generator was designed to prevent it from connecting to the rest of the power system without first syncing to that exact rhythm: 60 hertz. But Assante’s hacker in Idaho Falls had just reprogrammed that safeguard device, flipping its logic on its head.

At 11:33 a.m. and 23 seconds, the protective relay observed that the generator was perfectly synced. … It opened a circuit breaker to disconnect the machine.

When the generator was detached from the larger circuit …(and)… relieved of the burden of sharing its energy with that vast system, it instantly began to accelerate, spinning faster, like a pack of horses that had been let loose from its carriage. As soon as the protective relay observed that the generator’s rotation had sped up to be fully out of sync with the rest of the grid, its maliciously flipped logic immediately reconnected it to the grid’s machinery.

The moment the diesel generator was again linked to the larger system, it was hit with the wrenching force of every other rotating generator on the grid. All of that equipment pulled the relatively small mass of the diesel generator’s own spinning components

Yup, it self destructed by reversing the logic of a safety relay. Brilliant and terrifying hack – both.

We are not prepared.

Russia – “unprecedented damage to pursue small tactical advantages”

From the article:

“No country has weaponized its cyber capabilities as maliciously or irresponsibly as Russia, wantonly causing unprecedented damage to pursue small tactical advantages and to satisfy fits of spite,” Assistant Attorney General for National Security John C. Demers, said in the Justice Department statement.

Hospitality Industry Jobs Killed by COVID

Hospitality industry jobs are f’d. Big time. You care. You need us/them/we. We take care of each other.

If you have never worked in the service industry, then you might not know that a Monday or Tuesday night (it varies by geography) are called “Industry Night.” And in every town there is/are one or two establishments that stay open a bit later and focus on catering to other professionals in the service field. If you are “industry”, special pricing and special consideration is given. And thus you ALWAYS tip your compatriots 20% or more. It’s an unwritten rule we all follow.

If you have never worked in the service industry, the people, like I was and still am, who behind the scenes make everything work smoothly, then their health, safety, economics and future, might not resonate with you.

But if you have always been served, and never the server, give it another 12 months and you will seriously care. Because you won’t have a pub or restaurant to go to.

From the article: https://www.npr.org/2020/09/29/917756656/pandemic-threatens-long-term-job-security-after-hospitality-industry-layoffs

“Nationally, hotel occupancy is hovering at around 50%, according to the American Hotel and Lodging Association. In urban areas, business may be even slower — in the 20% to 40% range.”

“Virtually all business travel has halted. … Conventions have canceled for the year, or postponed. Pretty much all we are seeing in hotels are the leisure travelers,” said Ed Grose, executive director of the Greater Philadelphia Hotel Association.”

I am not suggesting opening everything up and a return to the wishful and fictional recidivist memories of what makes America “great”. And I don’t have all of the answers. That’s the point; none of us do.

I am posting this as a former busboy, waiter, fill-in bartender-of-last-resort in my youth. It’s how you partially pay for college. Or at least it was for many of us.

I am proud to have kept the (your) cutlery and dishes sanitary and well rinsed, the industrial ovens and grills on giant wheels cleaned with just the right amount of industrial strength cleaners. The kind that eat into your skin if you don’t wear elbow length gloves. And again rinsed and washed so customers didn’t get sick.

You do your “industry” job “right” because it’s the right thing to do. And hey, don’t forget, we also eat and drink where we work. And we bring in our family and friends.

The food and beverage “industry” is honorable work. I’m proud to have done it for years. And I’m not too prideful to return to working in the industry of restaurants, bars, and hotels if I needed to. I bet the 6 AM prepper is still is terrified of paper cuts (tomato juice is a killer) and I bet they still slice the prosciutto last (it’s greasy so you do it last before cleaning the blade.)

In conclusion, as painful as it is to write this, we must *not* fully open the service economy back up until we solve COVID. All that will do is endanger, and sometimes, literally kill my friends in the industry.

And to achieve that, in a time of international crisis, the people in industry should not be forgotten.

The k in COVID

“…. we don’t need to know all the sufficient factors that go into a super-spreading event to avoid what seems to be a necessary condition most of the time: many people, especially in a poorly ventilated indoor setting, and especially not wearing masks.”

“As Natalie Dean, a biostatistician at the University of Florida, told me, given the huge numbers associated with these clusters, targeting them would be very effective in getting our transmission numbers down.” “
