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…”

    Hackers remotely raise fridge and freezer temperatures in French supermarkets — Hundreds of supermarkets across France had refrigeration units remotely tampered with, raising temperatures in fridges and freezers.

  3. background

    Attackers hit 30 US water systems — The intrusions were consistent with methods used by the Iranian-backed CyberAv3ngers group, amid broader CISA warnings of Iranian-affiliated cyber targeting following the US-Iran war.

  4. background

    Cyberattack halts Australia's second-largest raw sugar producer — The incident shut down milling and cane haulage operations; a Russian-speaking group called The Gentleman claimed responsibility.

  5. background

    Handala Hack group claims attack on medical device maker Stryker — The Iranian-linked group said the attack, which remotely wiped associated devices worldwide and put Australian hospitals on alert, was retaliation for the bombing of an elementary school in southern Iran.

  6. 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.

  7. background

    Idaho National Laboratory confirms cyberattack — The US nuclear research lab confirmed hackers breached its systems and leaked human resources data.

  8. background

    Hacker sabotages Maroochy water treatment plant in Queensland — Remote interference with wastewater pump radio communications and alarms released more than 800,000 litres of untreated sewage into local waterways over three months, becoming the first attributable case of operational technology hacking.
