The University of Auckland is warning students to be careful after its arts server was accessed by "unauthorised parties".
A university spokesperson said today that the server, used for holding postgraduate enrolment applications, summer scholarship applications, doctoral research applications, and 2007 PHD expressions of interest, had been accessed unlawfully.
More than 4500 students who may have had their information accessed were sent an email warning them of the breach, and advising them to be careful.
"Expert forensic analysis has been undertaken in an effort to determine the nature of any data accessed on this server," the spokesperson said.
"Unfortunately, this testing is inconclusive and while there is no evidence that the information was accessed, it cannot be ruled out."
