Gentlemen ransomware disrupts Mackay Sugar mills, halts Queensland harvest
Gentlemen ransomware halted two Mackay Sugar mills during peak crushing, exposing supply-chain fragility in Australian sugar exports. Company statements confirm external IT access but withhold actor details; ESET links the group to prior RaaS operations. Payment reporting rules and potential data publication create near-term compliance and operational triggers.
Restoration work continues with partial harvesting expected this week. Next indicators will be either a data dump on the Gentlemen site or an ACSC-mandated payment disclosure within the statutory window. Supply contracts to export markets now carry explicit force-majeure risk tied to the unresolved access.
ACSC: Public data publication by Gentlemen within 14 days if no ransom reported under Australian disclosure rules.
