Mackay Sugar, Australia's second-largest sugar producer, reported a cyberattack on June 10, 2026, affecting key operations during the critical crushing season. Two of its three mills were offline, prompting the company to engage cybersecurity experts and implement manual workarounds. As of June 15, operations were slowly being restored, with a focus on safety and business continuity.
The ransomware group 'The Gentlemen' claimed responsibility, and while no data leaks were reported, negotiations appeared to be ongoing. The incident raises concerns about potential impacts on industrial control systems and the associated timelines for recovery.
