- Some people allegedly say that the US should treat heads of companies like they do in China, when found guilty of certain crimes. Allegedly.
- Sadly this instantly became a political football, with the states pointing fingers at Iran, but Trump was not wrong in this case. This is gross incompetence at all levels — IT malpractice if you will.
CISA and its predecessors have been warning utility operators about critical infrastructure vulnerabilities for what, 15 years at this point? That goes back to the first Obama administration.
Yet here we are in 2026 and these utilities are still connecting these things to the raw Internet with default passwords. You cross a threshold where you're being deliberately careless.
When you are putting more effort into securing your Plex server on your home network then public utilities are taking on machinery that dumps chemicals into the local water, something is not right and finger-pointing isn't going to fix it.

- CISA was formed in 2018, so not quite 15 years but closer to half that. The security industry as a whole has been yelling for longer than 15 years about the vulnerability of utilities. They've been marked as soft targets before the Bush administration restructured the government.by dylan604
- Until the people in charge face jailtime for hurting innocent people, why would they care? The government shouldn’t be warning, it should be ordering and imprisoning. And funding and educating where there are genuine gaps.
- Yes, utilities shouldn’t be negligent, but national security is 100% the federal government’s responsibility. If the vulnerabilities were so trivial, then it’s even more damning that the federal government was caught with its pants down, particularly since they were the only ones who knew they would be starting a war.

Your entire comment was finger pointing…
- Not IT malpractice and this where the industry diverges. IT folks usually don’t work on or understand these systems.
Which is one of MANY problems OT faces. IT best practices don’t suffice in OT and even when they do, most of these orgs are too resource hamstrung to do anything about all of the fires they have to put out.
Not to mention all of the OT vendors who flooded the market with tools instead of people being taught the boring process driven work.
by fathermarz - Absolutely 100% spot on. It’s not a political issue, it’s a technical issue. Disconnect them from the internet. Run your security patches. Check your logs. Water supplies are pretty important, do your job.by lorreyfum

I work with PLCs. Default passwords of not, the idea that such weakly secure devices are being made accessible from the public internet boggles my mind.
by andyjohnson0 - I think it's less carelessness and more the inability to attract (pay) people who have the technical knowhow to properly secure infrastructure. Even a lot of developers are poor network engineers and treat IT like magic at their own companies.by Avicebron
- There can be surprisingly few critical components and processes in a water and sewerage network due to gravity-fed designs (far more cost efficient), large buffers (water reservoirs, sewage sumps, etc) allowing intermittent operation of otherwise critical components, retained ability for humans to manually operate equipment, and also the fields of availability and safety engineering which typically prefer elimination of software failure modes by designing equipment to not rely upon software.
The aim of a water network is to:
1. Take water from a water source (elevated dam -- strongly preferred, river, ocean) and as much as possible, gravity feed it to a treatment plant.
2. Treat the water using processes that are simplified/fail-safe as much as possible and could be operated manually by humans if necessary. This is where availability and safety engineers would design equipment to not be dependent on software and instead use mechanical or analogue electronics control.
3. Pre-position treated water as much as possible at ~50-90m hydraulic head (~500-900kPA) above the water faucets where people want to use the treated water and provide a buffer for X days of usage. Any pumps between the treatment plant and elevated storage therefore only need to operate intermittently to refill the buffer.
Sewerage networks have similar aims:
1. Let sewage flow as much as possible downhill to the treatment plant via gravity. Where a rising main (elevation gain) is required, place a large enough sump for X hours/days of usage and pump up to higher elevation from the sump.
2. Treat the sewage using processes that are simplified/fail-safe as much as possible and could be operated manually by humans if necessary. For example, a compressor used for aeration can be manually switched on/off with a mechanical switch and plugged into a diesel generator, and not require someone logging in with multi-factor authentication to a laptop to issue a command to a PLC to turn on the compressor.
3. Design overflows into the system for emergency release of partially or untreated sewage, and practice this process as part of disaster recovery exercises. This is generally an aim arising due to risk assessment process that says building a $1bn sump with 8 independent pumps is cost prohibitive versus the 1-in-200 year chance of untreated sewage messing up a downstream river for a few weeks.
Ultimately a lot of the cybersecurity risk comes down to government appetite to accept 1-in-1000 (or whatever) year failure modes. Is it worth investing now in triple modular redundant automated control systems (mostly used in safety-critical sectors such as aviation and space), or installing a just-in-case diesel generator at every one of 500 pumping stations across a region, or building $10bn of sewage sumps to hold sewage for up to a month, or building 2 treatment plants instead of 1 and using different technology for each, or hiring and training more humans to regularly exercise manual control and operation of a network, etc? Or just accept that once every 1000 years, some water rationing may be required, or a downstream river will be polluted for a few weeks?
by dhx - The playbook, per federal officials, was crude but effective: attackers remotely accessed internet-facing operational technology, changed device IP addresses and passwords, and locked utility operators out of their own monitoring and control systems, NBC News reported. The PSA is now pleading with utilities to do the bare minimum - pull programmable logic controllers off the open internet and put them behind gateways and firewalls, use actual passwords, and restrict which devices are allowed to talk to one another.by lorreyfum

I much prefer the non-vendor perspective on this. Andy Krapf, co-chair of the Water ISAC, has a great breakdown about the status quo systemic problems that water faces today.
by fathermarz - > Censys ARC identified 4,148 Internet-exposed hosts that respond to EtherNet/IP and self-identify as Rockwell Automation/Allen-Bradley. The United States remains dominant at 71.0% (2,945 hosts), with Canada a clear second at 11.5% (476 hosts).
Describe the network security of the industrial automation industry and their customers in a single statement. Lol.
by BlackRabbit1 - It’s far worse, just last week I was assessing some architecture and there’s still dial up and 3G connected devices in some of the most critical infrastructure around..by tamimio
- And how many more are on the same internal networks as dozens or hundreds of ordinary Windows desktops on which municipal workers are checking their email? Hardly better.by closeparen
- The numbers are a bit lower if you exclude honeypots (~2k hosts): https://www.shodan.io/search/report?query=rockwell+port%3A44...
And the problem has actually gotten better over the years:

The situation used to be worse with things like the Lantronix password recovery service (i.e. a UDP port that would just send you the device password without any auth). It's still not ideal and takings things offline isn't easy (https://blog.shodan.io/taking-things-offline-is-hard/) but it's getting better (slowly).
