Hackers broke into a server at the University of Technology Sydney and published the usernames and passwords of dozens of staff accounts on a UTS web page.

On the defaced page the hackers identified themselves as “Apollo” and “0day” and wrote “Greets to ASIO, sup boys” before ridiculing UTS over its security.

The defaced UTS page that contained the usernames and passwords of staff accounts.

“Dear, Ugliest Tower in Sydney. Hire some staff who actually know what they are doing,” the hackers wrote.

Anne Dwyer, UTS deputy vice-chancellor (corporate services), said the breach was detected by the university's IT staff at 7:45am on Saturday. Dwyer said the affected machine was locked down and services were restored by 9am on Sunday.
