The Australian parliament is investigating a major technical disruption that resulted in MPs and senators losing email access over the weekend, raising fears of a widespread cyber-attack.The Parliament House outage came as the Nine Network scrambled on Sunday to fix “technical issues” that plagued its weekend programming in Australia. A spokesperson for the Department of Parliamentary Services – which oversees Parliament House in Canberra – said some services on DPS-issued smart phones and tablets had been disrupted and not all were back to normal.
“DPS is also working to investigate the cause of the disruption and the Australian Cyber Security Centre is providing advice as part of that process,” the spokesperson said. “DPS is working to resolve the issues and some services have been restored.”The attack came as the Nine Network’s Weekend Today show did not air in its usual Sunday timeslot of 7am to 1pm and viewers were unable to tune into Nine’s panel show Sunday Sport.It is not clear if there is any link between the two incidents.Nine Entertainment, the owner of the Sydney Morning Herald and the Age newspapers, confirmed it was responding to “technical issues”.“At this stage, we are working through the impacts across the network and will provide an update as we resolve the systems,” a spokesperson said on Sunday. Nine’s National Rugby League coverage, 6pm news bulletins and Sunday evening schedule including 60 Minutes and Married At First Sight would go ahead as planned, the network said.An anonymous source told the Reuters news agency that Nine management informed staff that it suspected a “malicious” cyber-attack was responsible for the technical issues.The Australian Financial Review, another Nine-owned outlet, reported the suspected attack also disrupted publishing operations at its Sydney headquarters.
Australia’s shadow treasurer, Jim Chalmers, said the situation was “serious” and called for a further investigation into the origin of the problems.“These are very concerning reports,” he told reporters. “What we’re hearing about here is a serious, and sophisticated, targeted attack on a media organisation.”
