People use 1000x more water than they need to drink.

If a water supply chain attack happened, we would just distribute bottled water for drinking, and people would go without washing for a few days whilst the issue was sorted.

Bottled water production is already big enough that delivering a bottle a day per person in new York is within the scale of the current production and retail networks scope.

It wouldn't cause the mass casualties an enemy might assume.

It's actually insane to me that the nation convulsed over the inability to get water to flint Michigan and people are still over here doing "no one actually deserves water, you use too much of it anyway"

Iran doesn't need to cause mass casualties. They just need to make US citizens hate the war in Iran.

Trouble is, there's a good chance that a large portion of the population will then be in favour of ending the war by escalating it to the point of flattening Iran. And that portion of the population has somewhat of a correlation with the political base of the current administration.

Exactly how big do you think those bottles would be?

Who exactly is this "we" in 2026 ?

The only thing I can see is some political crony company getting a big payment from the federal budget to take on the "burden" of doing so. But then not actually distributing enough water so they can still price-gouge individuals because we wouldn't want people to become entitled, right?

Wasn't there a Defcon or Derby talk about this years back? (The insecurity, not the Persian angle)

Struggling for a source.

Guy had the energy of that one Simcity 2000 character who bugs out if you cut back on funding that you'll regret it. Early twenty aughts IIRC?

Not sure about defcon, but Buckminster Fuller wrote waay back in the sixties about the New York's vulnerability to a fresh water supply attack.

If you haven't read it Operating Manual For Spaceship Earth is one of my favorite books.

I think this landscape is littered with simulated systems as honeypot. Once you have it a normal adversary would stop searching, besides regular checks that the gun still works.

Why are water systems still on the internet? They should be completely cut off. If necessary, remote access must be from dedicated devices only, only to a mirrored view, and never for remote control.

DOGE eliminated 1/3 of CISA staff in 2025. Trump reduced the 2026 CISA budget by $491 million (17%). Trump intends to slash their budget by an additional $707 million in 2027.

The ICE budget was just increased by $70 BILLION, bringing its total to >$200 billion.

CISA staff doesn’t do security patches and updates on local water supplies. You’re mixing a lot of stuff around there, none of it relevant to the discussion.
halJordan7 minutes ago
CISA is the one who mandates these controls and who manages the public/private relationship. Who issues the active exploration warnings. Who suggests legislation to prevent this in the future, including mandatory software updates.

If your question was only a trite recitation of the fact that private enterprise consistently refuses to practice cybersecurity then you've added nothing.

If your question was about who watches the watchers and what we're doing about the fact that private enterprise refuses to practice cybersecurity then it was an incredibly relevant statement.

The Federal Bureau of Investigation (FBI) and Environmental Protection Agency (EPA) are issuing this Public Service Announcement (PSA) to warn critical infrastructure asset owners and operators that malicious cyber actors (MCAs) are conducting cyber attacks targeting Operational Technology (OT) devices, including Rockwell Automation/Allen-Bradley Programmable Logic Controllers (PLCs), specifically MicroLogix 1100 and 1400 series. Since 27 July 2026, Water and Wastewater Sector (WWS) utility companies in at least seven states have reported incidents to the FBI, and some of that activity degraded water operations. While the FBI has only observed this behavior with the referenced Rockwell PLCs, similar considerations should also be made with other branded PLCs.

After remotely accessing internet-facing devices, the actors changed the IP addresses and passwords, resulting in a loss of monitoring and control functionality. To reduce the risk of compromise, the FBI and EPA recommend removing PLCs from direct internet exposure via secure gateway and firewalls, setting up strong, unique passwords, and utilizing an access control list (ACL) to allow only authorized communication between expected control system devices.

Did they literally just leave the water supply plant management software out available on the open internet? Hard to even call this a hack!
hubbahubbahubbaabout 1 hour ago
Does anyone recall the Colonial Pipeline outage? They had their IT and OT networks segregated but without billing capacity nothing else mattered. You didn’t expect them to let the petrol flow for free, didja? All that it takes is for a “jump box” that spans or bridges supposedly segregated networks to be p0wned to permit compromise of the soft and chewy center.

I mean

Some of these municipal water plants in the US are independently operated by municipalities of awfully few people and even fewer resources to spare, often serving relatively vast areas…

It’s probably not how you or I would set things up—especially after many years of warnings and slick best practices guides-but I can sympathize with “if it’s not broken…”-style maintenance, especially at the local level.

These things have lifespans measured in decades, and budgetary cycles to match… and for all of CISA’s good work (on limited budgets, and with power that’s more persuasive than fearsome) [0], it seems hard to get all 148,000 [1] system operators to afford to care, much less to afford to fix things—much less to check their work.

Who connected the systems to the Internet in the first place?

Why?

toomuchtodoabout 1 hour ago
Yes. The last federal administration attempted to use CISA to encourage better cyber outcomes for water supply systems, and the water industry and Republican states sued over it. There is no will to fix this, only to push the liability elsewhere.

When will the public figure out that many IT exploits are the result of malpractice by developers and network adminstrators, and the businesses employing them? We're building and operating bridges that we know will collapse. Our products are nearly indefensible, literally - they can't realistically be secured except at great expense. We talk about the imbalance between costs of attack and defense; we made that imbalance.

The big LLM security threat is arguably just a revelation of the sh-ty work our field has accepted. Maybe we need to become actual engineers and invest in building proper, reliable, safe systems (which includes not being a dangerous risk for fraud, surveillance, and addiction). The 'anything goes' extreme disruption of many current SV corporate leaders and their technology is, in a way, a culmination of what they've always done.

The good news is that LLMs used properly might make proper engineering less expensive. The LLMs will more likely be used to make sh-t cheaper, so we can make more of it. Unless of course we take action.

If I was in a power position, I could theoretically channel this water into my own private reservoirs and locations like private land, bunkers, etc to weather a disruption, and blame Iran and it would be really hard to validate.

I mean if I was in a power position I would have also disrupted those in positions who would be validating me, made journalism much harder and have algorithms with LLM-enhanced astroturf accounts running to label any questioning of the official narrative as conspiratorial or tin-foil hat.

I would probably be on sites like this downvoting people who said things like this. Yes. That's how I would do it. edit: Oh I might even consider channeling that water to my data center friends!

But they wouldn't need to false-flag an excuse to capture and privatize resources, they could and would just do that openly. The government can just take whatever it wants through eminent domain.

I'm no Trump supporter and this war was a big mistake, but justifying a nation poisoning another's civilian water supply is a bit upside down.

We don't follow "rules" in war anymore, according to "Secretary of War" Pete Hegseth. We show no quarter and take no prisoners, we pursue "maximum lethality, not tepid legality."

That's American policy now. The gloves are off, no holds barred, everything and everyone is on the table. So I guess we reap what we sow.

They always point to a state actor to skirt liability for their own shitty IT work. Then the dim evil journalists swallow it whole, later regurgitating it for their eager little baby bird subscribers.

If there were actual penalties for rawdogging a PLC (or any other control system) on the internet, shit like this wouldn’t happen.

This conspiracy theory would make more sense if he wasn’t working so hard to divert blame away from Iran: https://www.politico.com/news/2026/07/31/trump-minnesota-wat...

> “I blame it on Minnesota because they are grossly incompetent,” Trump said at a cabinet meeting at Camp David on Friday, adding that Walz is “corrupt” and “Iran has bigger problems than worrying about Minnesota.” Asked later if he could rule out Iranian responsibility, Trump said, “ I don’t think there was an Iranian cyberattack. I think Minnesota ought to get its act together.”

The rest of the thread demonstrates well enough that flagging would have been a better response than trying to engage with it factually.

But I do appreciate the attempt anyway.
