Description
On or around July 1, 2022, Port Phillip Prison in Melbourne’s Truganina area experienced a sophisticated cyber attack by anonymous hackers who gained control of the facility’s computer systems. The breach prompted immediate operational disruptions, including the suspension of all in-person and video visits to the prison’s approximately 1,000 inmates. Management implemented heightened security protocols within the jail to safeguard staff and prisoners, though G4S, the prison’s operator, confirmed no direct harm to individuals. Victoria Police and the Victorian Government’s Cyber Incident Response Team were notified to investigate the incident. Phone communications were restricted, permitting only essential calls from authorized professionals such as social workers and lawyers. Corrections Victoria acknowledged “network issues” affecting prisoner communications, prioritizing urgent welfare matters while limiting general access.
The attackers reportedly demanded ransom payments to restore system control, though specific demands or payment details were not disclosed publicly. G4S and Corrections Victoria collaborated to resolve the technical disruptions, emphasizing that prison safety and security remained uncompromised throughout the incident. Port Phillip Prison, Victoria’s largest correctional facility with a capacity of 1,087 inmates, maintained its maximum-security operations despite the network compromise. The prison’s infrastructure, including its 13 accommodation units and 20-bed hospital, continued functioning under heightened vigilance. Restoration efforts focused on reestablishing full communication capabilities while authorities worked to mitigate the attack’s impact. No further details regarding the attackers’ identity, methods, or long-term consequences were confirmed in the immediate aftermath.
