Australian unis lag on cyber measures

Some of the country’s top universities — along with their UK and US counterparts — are lagging on basic cybersecurity measures, subjecting students, staff and stakeholders to higher risks of email-based impersonation attacks, according to new research.

Cybersecurity and compliance company Proofpoint released the results, which found that 97% of the top 10 universities across each country are not taking appropriate measures to proactively block attackers from spoofing their email domains, increasing the risk of email fraud. According to the analysis, universities in the United States have the poorest levels of protection, followed by the United Kingdom and then Australia.

These findings are based on Domain-based Message Authentication, Reporting and Conformance (DMARC) analysis of the top 10 universities in each country. DMARC is an email validation protocol designed to protect domain names from being misused by cybercriminals. It authenticates the sender’s identity before allowing a message to reach its intended destination. DMARC has three levels of protection — Monitor, Quarantine and Reject* — with Reject being the most secure for preventing suspicious emails from reaching the inbox.

The full findings of Proofpoint’s DMARC analysis show:

  • Only one institution (in Australia) out of 30 universities implemented a Reject policy to block unqualified emails.
  • 17 (57%) of the surveyed universities implemented a Monitor policy, while only four (13%) of the 30 universities implemented a Quarantine policy.
  • Eight out of the 30 universities (27%) do not publish any level of DMARC record, five of these being in the United States.
  • In Australia one university had no DMARC record; two universities implemented Quarantine measures; six implemented Monitor; and only one university implemented a Reject policy.
  • While 80% of the UK’s top universities implemented some level of DMARC protection, no UK university implemented DMARC’s highest level of protection (Reject policy), with the same findings uncovered for the US.
     

“Higher education institutions hold masses of sensitive personal and financial data, perhaps more so than any industry outside health care. This, unfortunately, makes these institutions a highly attractive target for cybercriminals. The pandemic and rapid shift to remote learning has further heightened the cybersecurity challenges for tertiary education institutions and opened them up to significant risks from malicious email-based cyber attacks, such as phishing,” said Steve Moros, Senior Director, Advanced Technology Group, APACJ at Proofpoint.

“Notably, Proofpoint’s recent Voice of the CISO report found chief information security officers (CISOs) in the education sector felt the least backed by their organisation. In line with these findings, the World Economic Forum reports that 95% of cybersecurity issues are traced to human error, highlighting that many CISOs still significantly underestimate the risk posed by users. With this, only 47% of education-sector CISOs believe users to be their most significant risk.

“Email remains the most common vector for security compromises across all industries. In recent years, the frequency, sophistication and cost of cyber attacks against universities has increased. It’s the combination of these factors that make it especially concerning that only one of Australia’s top 10 universities is fully DMARC compliant,” he said.

With the shift to remote learning and now hybrid learning, these figures will continue to climb. The lack of protection against email fraud is commonplace across the tertiary education sector, exposing countless parties to impostor emails, also referred to as business email compromise (BEC).

BECs are a form of social engineering designed to trick victims into thinking they have received a legitimate email from an organisation or institution. Cybercriminals use this technique to extract personal information from students and staff by using luring techniques and disguising emails as messages from the university IT department, administration or campus group, often directing users to fake landing pages to harvest credentials.

“Email authentication protocols like DMARC are the best way to shore up email fraud defences and protect students, staff and alumni from malicious attacks. As holders of vast amounts of sensitive and critical data, we advise universities across Australia to ensure that they have the strictest level of DMARC protocol in place to protect those within their networks,” said Moros.

“People are the last line of defence against email fraud but remain one of the biggest vulnerabilities for organisations. DMARC remains the only technology capable of not only defending against but eliminating domain spoofing or the risk of being impersonated. When fully compliant with DMARC, a malicious email can’t reach your inbox, removing the risk of human interference,” said Moros.

The analysis was conducted in May 2022 using data from QS Top Universities.

*Monitor allows unqualified emails to go to the recipient’s inbox or other folders; Quarantine directs unqualified emails to go to the junk or spam folder; and Reject, the highest level of protection, blocks unqualified emails from getting to the recipient.
