The Royal Australian Air Force has confirmed that a hacker defaced its website on 13-14 July, in an attack the perpetrator described as a warning message to stop racism against Indian students in Australia.
The hacker left a message on the site which read: "This site has been hacked by Atul Dwivedi. This is a warning message to the Australian Government. Immediately take all measures to stop racist attacks against Indian students in Australia or else I will pawn all your cyber properties like this one."
The site was temporarily offline and is now operating normally.
An RAAF spokesperson said that the defaced site was an external-facing site and was not used to conduct RAAF business or connected to any operational Defence system. As a result the RAAF claimed that no sensitive information was compromised.
The Air Force was not forthcoming on the technical details of the hack and said it would be inappropriate to comment further as the Defence Security Authority was conducting an investigation into the incident.
