PUBLIC NOTIFICATION –
WESTERN SYDNEY UNIVERSITY CYBER INCIDENT

31 July 2024


Since unauthorised access to Western Sydney University’s IT network was
discovered in January 2024, the University has been undertaking forensic
investigations in line with our due diligence and legal obligations to determine
the full nature, scope and scale of the incident.

As a result of the ongoing investigations, the University issued this public
notification on 31 July 2024 about unauthorised access to the University’s
storage platform, known as the Isilon storage platform (Isilon). In particular,
the University is drawing this public notification to the attention of our
University community, which includes but is not limited to, our former and
current students and staff.

The University unreservedly apologises for this incident and the impact it is
having on our community. The University is committed to transparently rectifying
this matter and will keep our community updated as our investigation progresses.

Update on the ongoing investigation

After the University notified approximately 7,500 impacted individuals and our
community about a breach to our Microsoft Office 365 environment in May 2024,
the University confirmed personal information in Isilon was also subject to
unauthorised access. Isilon holds My Documents information, departmental shared
folders, and some backup and archived data.


We have been and will continue to analyse the very large and complex dataset to
properly understand the impact the unauthorised access to Isilon has had on
individuals’ personal information. The University is now in a position to
confirm:

 * There is evidence of access to approximately 580 terabytes of data across 83
   of the 400 directories in Isilon.
 * The investigation to date indicates unauthorised access to Isilon occurred
   between 9 July 2023 and 16 March 2024. 
 * Our initial review of Isilon has found personally identifiable information
   (PII) was accessed, including names, contact details, dates of birth, health
   information, sensitive information relating to workplace conduct and health
   and safety matters, government identification documents, tax file numbers,
   superannuation details and bank account information.

Based on its forensic investigation to date, the University has no evidence that
this incident extends beyond the University’s Microsoft Office 365 and Isilon
environments.

The University has not received any threats to disclose private information or
demands in exchange for maintaining privacy. The University has dark web
monitoring in place and there is no evidence to date that the data has been
uploaded. 

The University has not detected any further unauthorised access to Isilon since
remediation work took place. The University continues to engage with the
authorities in relation to the perpetrator of the Isilon incident.

What steps the University has taken

The University is working with Australia’s leading digital forensics and
incident response team at CyberCX and relevant authorities, including the
National Office of Cyber Security, Office of the Australian Information
Commissioner, NSW Information and Privacy Commission (IPC), Australian Federal
Police, Australian Cyber Security Centre, Australian Signals Directorate and
Home Affairs. The NSW Police Force’s Cybercrime Squad is conducting an
investigation under Strike Force GIRRAKOOL.

To protect University staff, students and stakeholders, the University sought
and was granted an interim injunction in the NSW Supreme Court to prevent
access, use, transmission and publication of any data that is the subject of the
incident. This includes data in Isilon that was accessed without authorisation.

The University’s leadership and Board have taken a number of steps to remediate
the issue and further protect staff and students, including completing a
password reset, enhancing detection monitoring, implementing additional firewall
protection, increasing our cyber security team capacity, and reviewing data
storage and retention practices.

On 31 July 2024, the University drew this public notification to the particular
attention of its community in emails issued to students, staff and alumni with
information about the steps they can take to protect themselves, and the support
services made available to them by the University. The University also issued a
media release to draw this public notification to the attention of all those who
may be impacted.

The next steps

The University will endeavour to notify individuals about the impact on their
personal information in the coming weeks. However, due to the volume and
complexity of the data, the University will not be able to issue individual
notifications to all those who may be impacted.

What action should you take?

This public notification will help ensure our community stays vigilant to any
signs their data may have been accessed.

The University has engaged IDCARE, Australia’s national identity and cyber
support service, to provide free advice and support to members of our community
who may have questions about how to protect themselves when identity information
may have been compromised.
