OT hacking of critical infrastructure rises, experts warn AI will accelerate it
From a 2000 sewage spill to French supermarket fridges and US water systems, attacks on physical control systems are escalating.
What to know
- Operational technology (OT) hacking — attacks on physical control systems, not just computers — has been rising since the first documented case in Queensland in 2000.
- Recent incidents span French supermarket fridges, US water systems, an Australian sugar mill and a medical device maker, often tied to state-linked or politically motivated groups from Iran and Russia.
- Experts warn that IT breaches, such as the 2025 Microsoft SharePoint hack affecting the US National Nuclear Security Administration, can leave hackers dormant inside systems until they strike OT targets.
- As geopolitical tensions rise and AI technology matures, analysts expect the frequency, sophistication and human-life risk of OT attacks to increase.

ABC traces 26-year rise of OT hacking, flags AI as accelerant
ABC Australia published an explainer linking the Maroochy incident to recent attacks on supermarkets, water systems, a sugar producer and medical device infrastructure, warning that OT hacking is increasing and will likely be amplified by AI as the world destabilises.
“They get into a system, lie dormant for a very long time and when there is an opportunity, get into sensitive areas…”

background
China-sponsored hackers breach 400+ agencies via Microsoft SharePoint — The intrusion hit more than 400 agencies globally, including the US National Nuclear Security Administration, which manages the US nuclear stockpile and reactors on warships and submarines; analysts say dormant IT access of this kind can later enable OT attacks.
