EXCLUSIVE: AN Indonesian hacking collective calling itself "BlackSinchan" is publishing encrypted passcodes of Australian authorities including figures in the Australian Federal Police after breaking through a weakness in the national Crime Stoppers website.
Police forces in New South Wales, South Australia, Tasmania and various state branches of Crime Stoppers had their email details released as "pay back" for the Australian Government's spying on Indonesia.
Along with the information, the group wrote, "This is the payback for Spying Indonesia !
We Love Australia , We Love our Country ! BUT STOP SPYING AT MY COUNTRY !
AND REMEMBER THIS IS NOT FOR FAMOUS ! THIS IS FOR PAYBACK !!!!
WE WILL BE BACK !!"
The information has been published repeatedly online.
The attack follows increasing tensions between Australia and Indonesia following revelations that Australian surveillance of its northern neighbour included tapping the phone of Indonesian President Susilo Bambang Yudhoyono and his wife in 2009.
The Indonesian Government has also put a hold on helping Australia to deal with people smuggling and asylum seekers.
Enforcement agencies were not the only ones included in the information dump.
Accounts from the government-funded Australian Institute of Criminology and National Drug Law Enforcement Research Fund were also published.
APN understands the breach began with hackers infiltrating the government sites by exploiting a hole in the Crime Stoppers webpage.
Once through, they were able to access the AIC and NDLERF - both of which have sites on the same server.
AIC learned of the breach on Friday morning but it has so far refused to discuss the issue except to say that it was aware of it.
The NDLERF website is undergoing a redesign and was taken offline once the cyber threat was revealed.
It is unclear whether such "hashed passwords" are enough to give the hackers access to sensitive information.
One government source told APN the attack was "not really a threat".
"The Indonesian hacking crew are just looking for vulnerable government sites and having a crack."
Crime Stoppers has urged people wanting to contact them to continue to use the 1800 333 000 number in preference to the website.
The Australian Federal Police and New South Wales Police are being sought for comment.
