AusCERT Week in Review for 27th August 2021

Greetings,

Hot topic of the week is the recently passed bill which will allow the Australian Federal Police (AFP) and Australian Criminal Intelligence Commission (ACIC) to access the computers and networks of those suspected of conducting criminal activity online, which raises the question: 'How do we as a CERT tell the difference between a hacked system and a legally compromised one?' You can read more through these articles from ZDNet and InnovationAus.

This week AusCERT joined teams from 21 other countries to take part in the annual APCERT Drill, designed to improve regional responses to emerging cyber security threats. The theme of this year's APCERT Drill was "Supply Chain Attack Through Spear-Phishing - Beware of Working from Home". This exercise reflected real incidents and issues that exist on the Internet. The participants handled a case of a supply chain attack triggered by spear phishing. Narayan and Vishaka represented team AusCERT and did an outstanding job, especially considering it was their first time. We are proud of the contribution by Geoffroy Thonon, our Operations Manager who was part of the planning committee who worked tirelessly to deliver the drill.

Great news for Members! You can now opt to receive AusCERT Bulletins as a daily digest issued at the end of each business day. Subscribe now through the Member Portal, instructions can be found here. Alternatively, you can send an email to the membership team.

Today is Wear it Purple Day which is a way to show young LGBTIQ+ members of the community that they have a right to be proud of who they are. The aim is to create safe spaces in schools, universities, workplaces and public areas to show LGBTIQ+ they are supported and belong.

Have a great weekend!

Near-perfect forgeries of the federal government's COVID-19 vaccine digital certificate can be made in 10 minutes using free software, a member of the public has discovered.
Richard Nelson, a software engineer in Sydney, has found an "obvious" security flaw in the Express Plus Medicare app allowing him to make vaccine certificates with any name and date of birth and featuring the background animations meant to prevent forgery.
The Prime Minister has previously said the certificates are a "credible and effective" way for states to administer exemptions from aspects of lockdowns.

Australian businesses are incorrectly relying on what they think is a loophole in notifiable data breach laws to avoid reporting ransomware infections.
The Office of the Australian Information Commissioner (OAIC) warned that “a number of entities” in the six months to June 2021 didn’t report ransomware attacks because they could not prove whether or not data was accessed or stolen.

Forty-seven government entities and privacy companies, including Microsoft, exposed 38 million sensitive data records online by misconfiguring the Windows giant's Power Apps, a low-code service that promises an easy way to build professional applications.
Security biz UpGuard said that in May one of its analysts found that the OData API for a Power Apps portal offered anonymously accessible database records that included personal details. That led the security shop to look at other Power Apps portals and its researchers found over one thousand apps configured to make data available to anyone who asked.
