AUSCERT 30 Years 30 Stories – Dushyant Sattiraju Attending the AUSCERT conference for the past six years and presenting for the past four, Dushyant Sattiraju speaks of the helpful platform AUSCERT has provided. As the Security Operations Manager at Deakin University, AUSCERT membership has enabled Dushyant to bounce ideas and receive timely, supportive feedback ensuring the university’s cyber safety. How did you first get involved with AUSCERT and what motivated you to become a member? When I first started at Deakin, I was the only security staff. As we didn’t have a history of security, I needed support. I reached out to the community to see if anyone was willing to share their stories about what they were doing and what they were they prioritising. AUSCERT was a welcoming community and I got to connect with other universities and organisations that had similar security history as me. The ongoing sharing of stories and learnings has been one of the main reasons for my involvement. What are some of the key benefits you’ve experienced as an AUSCERT member, both in terms of the resources and support offered? One of the key benefits of membership are the AUSCERT services. I used a few services at Deakin such as the take down system, along with the threat intel platform. I found the analyst in the team very supportive and ideal for bouncing ideas off. AUSCERT’s conferences are an interesting avenue to meet different people from different organisations and various sectors, which has been great as well. What advice would you give to someone considering becoming an AUSCERT member, and why do you believe that membership is valuable for organisations of all sizes and industries? You get a lot for what you pay for with the AUSCERT membership. Not only do you get access to the conferences and events, but you also get access to the community. The community is very generous in sharing and forthcoming. Trying to implement new technology? Ask your questions to the community and they’ll get back to you within minutes. AUSCERT has connected me to organisations that I had never met before, supporting discussions about our technology and security journey overall. Looking ahead, what do you think the future holds for AUSCERT, and how do you see the organisation continuing to play a vital role in the cyber security community? AUSCERT is great for connecting people. For example, there are a few subgroups, such as the university sharing community to increase collaboration and knowledge sharing. The past few years I’ve talked about our experiences and incidents we’ve had. I predict we will see a lot more of these stories in the future – a fantastic opportunity to continue learning.

AUSCERT 30 Years 30 stories – Daisy Wong Defining results-focused leadership, with a strong management connection, Daisy Wong is the Security Culture and Awareness Lead at Flybuys. Working with a disability, Daisy is an amazing thought leader and advocate for inclusive work environments. Daisy champions those with disabilities and shares why she appreciates AUSCERT’s inclusivity efforts. What advice would you give an organisation looking to prioritise diversity and inclusion, when hiring and retaining talent? For those reading, I have a physical disability which means I am in a wheelchair. Over the years, I have worked in a few organisations that weren’t prepared for me. I have arrived and found stairs, meaning I couldn’t even get into my workplace. I’ve experienced hiring managers ask inappropriate questions in interview settings such as – how do I make a cup of coffee and get back to my desk – a strange question, with nothing to do with the job. The number one thing I would recommend for organisations wanting to improve inclusivity is to ask the candidate or the person what they need to succeed. Don’t make assumptions that they cannot do something or make assumptions that they can. Create the ability during applications for accessibility information to be very clear. Although I have a physical disability, there are all different kinds of disabilities, for example, colour blindness, or audio issues, so it’s important to consider all disabilities – not just the visible ones. How has AUSCERT played a part in helping generate diversity and inclusion in the industry? AUSCERT has done a lot of good things relating to diversity in the industry. Firstly, the conference is always accessible. I’ve seen two other people in wheelchairs, and I’ve never had an issue getting up on the stage when presenting. Regarding the industry, AUSCERT is highly supportive of the Australian Women Security Network. I volunteer with this network, and they’ve always had a booth at the conference. AUSCERT also works with BDO, an inclusion technology company, showcasing how they support their initiatives. What strategies have you found most effective in creating an inclusive workplace culture? To create an inclusive culture for organisations, the best way is to ask the individuals and listen to their needs. Flybuys has done a great job; when I started, we had a conversation about my limitations and what I can do and can’t do. Since then, every event I’ve attended has been accessible and I don’t have to continually inform Flybuys. As an employer, you need open communication, a willingness to listen, and an ability to adapt and be flexible. How would you recommend organisations address discrimination bias in the workplace? Unfortunately, discrimination bias still happens, and organisations need to find ways to address them. The first thing to do is lead with empathy. Many individuals don’t understand that what they say hurts my feelings or makes me feel like I can’t ask for help next time. From a corporate or organisation point of view, training should be provided to staff because so many people make comments unconsciously. They may not have met someone in a wheelchair before and therefore might not know how to be helpful. For example, I don’t like my wheelchair being pushed without you asking, but if you see me struggling and you want to offer help, I do appreciate it. It’s about asking the person. How far do you think the industry has come and what do you think we can expect for the future? This is AUSCERT’s 30th year and 22nd conference, and only my second time, but I’ve noticed many changes. I’ve been in cyber industry for eight years, and I’ve already seen a lot of change. Firstly, there are more women. However, women still only represent 17% of the whole industry, meaning we’ve got a long way to go. That said, compared to other conferences, AUSCERT has a much healthier balance. AUSCERT values the encouragement of women in the industry, which I’ve observed AUSCERT apply to their own organisation by hiring females in roles.

Greetings, R U OK? Day serves as a powerful reminder of the significance of checking in on the well-being of others and actively listening to their concerns. In many cases individuals who are facing challenges may not openly express their feelings, and a simple empathetic conversation can make a world of difference. The act of asking “Are you okay” and genuinely listening, can provide emotional support and let someone know that they are not alone in their struggles. Meaningful connections and open dialogues about mental health contribute to building a supportive and compassionate community. Prioritizing mental health reduces the stigma and fosters an environment where people feel comfortable sharing their feelings and seeking help when needed. It’s a reminder that small acts of kindness and genuine concern can have a profound impact on someone’s life. The R U OK? Day website features a range of free resources for your workplace, home or community click here to visit their website. AUSCERT has always been an avid supporter and endorser of mental health support and services. This year at AUSCERT2023 we once again featured an on-site psychologist for attendees to visit and discuss anything from mental well-being right through to life coaching. We have created an on-going commitment to fostering a culture of support and understanding through promoting open conversations and creating a safe, inclusive environment for our community. Episode 15 of our Podcast explored the importance of understanding mental and physical well-being in the workplace with Dr Carla Rogers. Dr Carla Rogers, a renowned holistic psychologist, discusses the importance of understanding mental and physical well-being in the workplace. Dr Rogers explains the connection between mind and body along with techniques to help individuals identify, treat, and overcome challenges in the workplace. The Australian Department of Health also provides a useful resource – Head to Health which features a range of information resources to provide mental health support. In other news, some of our team ventured to the BSides Melbourne conference last weekend. We sat down with Lucas this week to hear his experience and highlights – you can read the full interview here. Also, there are still a few spots remaining in our upcoming Data Governance Principles and Practices training course, both the in-person session and online sessions.

Stay safe, stay patched and have a good weekend! The AUSCERT team

My Time on the BSide This week, a few AUSCERT staff members journeyed from sunny Brisbane to brave the crisp Melbourne air and participate in the annual BSides conference. BSides is a volunteer-driven initiative spearheaded by members of the infosec industry who share a common objective: to foster and support a thriving cybersecurity community. The conference offers a platform for first-time speakers, students, as well as new and experienced professionals to showcase their work in a friendly and welcoming environment. AUSCERT takes great pride in sponsoring this event and contributing to the growth of the cybersecurity industry in Australia. One of our AUSCERT team members who participated in BSides Melbourne last weekend was our Senior Software Developer, Lucas. This week, we had the opportunity to sit down with Lucas to delve into his highlights, favourite sessions, and other noteworthy aspects of the event. Here’s his first-hand account of the experience. Highlights One of my standout moments from the conference was teaming up with a colleague to take part in the Capture the Flag (CTF) competition. A CTF competition is composed of many different challenges that fall under different cybersecurity categories. The challenges vary in difficulty and are designed to test the participants cybersecurity skills, whilst also offering valuable hands-on learning and networking opportunities. These challenges provide a unique educational and training experience within a fun and competitive environment. As a software developer, I typically don’t engage in offensive security work. However, this challenge provided me with a unique opportunity to broaden my expertise and skills in this particular field. Achieving the 11th position in the challenge among 53 other competing teams was a proud moment for me. It demonstrated that I do possess a certain level of proficiency in this area and continues to motivate me to pursue further skill development in this field. Favourite Session One session that left a lasting impact on me was Paul McCarty’s talk on defending the software supply chain. As a software developer focusing on the development operations space, this session provided invaluable insights into crucial considerations and areas for improvement. In an era where the software supply chain faces increasingly sophisticated attacks, it’s imperative for software developers and engineers like me to comprehend how to safeguard against emerging and existing threats to the software supply chain. The session explored valuable open-source tools that can assist organisations in establishing new processes and developing tools to enhance the security of their software supply chains. The session put into perspective the breadth of the software supply chain and how it can be attacked, and it introduced me to some very useful open-source tools for visualising and improving the security of AUSCERT’s software supply chain. Interesting Aspects One particularly interesting aspect of the conference was the extensive focus on career support and guidance they offered. It was truly inspiring to witness the dedication to fostering professional development and the readiness to assist attendees at various stages of their careers. The conference featured sessions led by experts who offered invaluable advice and support, enabling individuals to expand and evolve in various aspects of their careers. Moreover, it encouraged attendees to explore new passions that might not yet exist in their current fields. In summary, my experience at BSides Melbourne was truly memorable, primarily due to the opportunity to connect with numerous outstanding individuals in the industry. The sessions were both relevant and engaging, and the warm and inviting attitude of the entire staff and community contributed to a friendly and welcoming atmosphere that everyone enjoyed!

Mikhail Lopushanski is the Chief Information Security Officer for Heritage Bank and has been in the information security space for close to 30 years. Involved with AUSCERT in its early days, Mikhail has an appreciation for the partnership that AUSCERT offers and its mission to help all organisation improve their information security.  How did you first become involved with AUSCERT, and what motivated you to become a member? I became an AUSCERT member in the late 90s. As an organisation, we required a partner, somebody that could help advise and mature our information security space. It was great having an organization that wasn’t connected to a vendor, government, or any particular area. AUSCERT helped my organisation to mature in that area with guidance, as well as providing us with alerts and starting to give us broader levels of alert capability than what we could do internally. How has AUSCERT evolved over the years, and what changes have you seen in the cyber security landscape that have affected the organisation’s work? AUSCERT has greatly developed since the late 90s. As a start-up coordinating globally, AUSCERT was able to provide information back to its members that was significantly up to date. You have to remember this is early days of internet and browser access. As AUSCERT developed, I’ve moved to several organisations and our needs have changed depending on our maturity. I found that AUSCERT was able to meet those needs regardless of what stage we were in. I’ve worked with AUSCERT across many projects, including setting up a threat intel group across the financial sector. AUSCERT fundamentally assisted me to set this up and to reach out to certain numbers that met the criteria of financial service spaces. I view AUSCERT as a true partner. How has your membership in AUSCERT impacted your organisation’s overall approach to cyber security? And what changes have you implemented as a result? AUSCERT is a partner that can help an organisation mature in this space. In my experience going from several organisations that are less mature in information security to other organisations that are quite mature, the needs from what we wanted AUSCERT to do changed from place to place. AUSCERT has certainly matured in this space over time. For a time they offered flying doctor service for incident response and they have really developed their capability for incident response, but also identification and threat intelligence and starting to provide quality IOCs and quality information to organisations. They shared this intelligence making it available across multiple industries. That development that AUSCERT created fell in line with how the industry over the years has also developed, becoming a real industry leader. Is there anything else you would like to add? Happy 30th AUSCERT and I look forward to working with you in the next few years!

Greetings, Who can believe that there are only a mere four months left until the end of the year – where has the year gone? Time really does fly by. With that said, the AUSCERT team are well and truly planning for next year’s conference and this year’s conference is already beginning to feel like a distant memory. To remind ourselves of the amazing time we had, we often enjoy revisiting and reliving the program of outstanding speakers and activities via our YouTube channel. One of our highlights for AUSCERT2023 was the significant presence of remarkable female speakers in our program. These include Tara Dharnikota’s session – “Staying ahead of evolving threats”, Jane O’Loughlin’s session – “What we do in the shadows” and our much-loved session led by Vanessa Wong & Shelly Mills – “You can’t ask that: Women in Cyber Security”. Not to mention our impressive keynote speaker Rachel Tobac, a globally renowned expert in the field of social engineering. Rachel is also chair of the board for the not-for-profit organisation Women in Security and Privacy (WISP) where she works to advance women to lead the future of privacy and security. Last week we celebrated Women In Cyber Day, an initiative aimed at promoting and supporting the advancement and support of women in cyber security. Increasing the proportion of women within the industry isn’t just about equity, it’s a strategic imperative for enhancing security, innovation, and the overall effectiveness of the field. Women often possess different skills that can complement those of their colleagues, including communication, attention to detail, and a collaborative approach to problem-solving. A wider range of perspectives is also beneficial when making decisions about security policies, products and practices, which can lead to better protection for all. Diversity fosters innovation and creativity, as it brings different perceptions that can lead to innovative solutions and approaches. To conclude, if you are looking for something to read across the weekend, NIST recently released an updated, draft guide detailing the creation of cybersecurity and privacy learning program. This is the first revision since NIST SP800-50 Building a Cybersecurity and Privacy Learning Program was introduced in 2003, a well-needed update. This initial public draft is open for community feedback until October 27, 2023. Click here to read the full document, NIST SP 800-50 Rev.1 University of Sydney data breach impacts recent applicants Date: 2023-09-03 Author: Bleeping Computer The University of Sydney (USYD) announced that a breach at a third-party service provider exposed personal information of recently applied and enrolled international applicants. The public university started operations in 1850 and has nearly 70,000 students and about 8,500 academic and administrative personnel. It is considered one of Australia’s most important educational institutes. Exploit Code Published for Critical-Severity VMware Security Defect Date: 2023-09-01 Author: Security Week Just days after shipping a major security update to correct vulnerabilities in its Aria Operations for Networks product line, VMware is warning that exploit code has been published online. In an updated advisory, the virtualization technology giant confirmed the public release of exploit code that provides a roadmap for hackers to bypass SSH authentication and gain access to the Aria Operations for Networks command line interface. Hackers exploit MinIO storage system to breach corporate networks Date: 2023-09-04 Author: Bleeping Computer [AUSCERT has identified the impacted members (where possible) and contacted them via MSIN] Hackers are exploiting two recent MinIO vulnerabilities to breach object storage systems and access private information, execute arbitrary code, and potentially take over servers. MinIO is an open-source object storage service offering compatibility with Amazon S3 and the ability to store unstructured data, logs, backups, and container images of up to 50TB in size. Its high performance and versatility, especially for large-scale AI/ML and data lake applications, make MinIO a popular, cost-effective choice. Australian authorities tire of excuses, delays on data breach disclosure Date: 2023-09-05 Author: iTnews Australian authorities had to formally invoke powers to get a client list from a breached IT services provider, as problems persist in getting organisations to notify data breaches in a timely fashion. The issue of Australian organisations either seeking to downplay or delay mandatory notification of a data breach was raised more than two years ago. A regulatory report, released Tuesday, shows the issue persists. “Prompt notification ensures individuals are informed and can take further steps to protect themselves, such as being more alert to scams,” Australian information commissioner and privacy commissioner Angelene Falk said in a statement. Defence Housing Australia investigates third-party provider hack exposure Date: 2023-09-07 Author: iTnews Defence Housing Australia has launched an investigation to determine if it, or the data of Australian Defence personnel, has been exposed in a cyber attack on a third-party service provider. The government business enterprise (GBE) said it is collaborating with the Defence on the investigation, which sought to establish – among other things – “if any Defence personnel or families’ information has been compromised.” Scams Australia: Alarming surge in the number of teens being exploited online Date: 2023-09-04 Author: 9NEWS The number of young Australians being targeted by scammers online has surged in the last year, with concerning levels of sextortion taking place, new data suggests. Statistics released today by Westpac Banks show the number of scams reported by customers under the age of 18 have almost quadrupled since last year, and have more than doubled for those under 30. The data was concerning and showed a growing trend of scammers using techniques such as sextortion, Westpac General Manager of Financial Crime & Fraud Prevention, Chris Whittingham, said.

Greetings, Spring has sprung! Just as we begin to make plans to dust off and organise our homes during this season, it’s a perfect opportunity to freshen up and enhance our cyber security measures. Regularly reviewing, updating, and optimizing our digital habits can go a long way in safeguarding our sensitive information and ensuring a safer online experience. Take the time this month to refresh your security strategies! We have a new episode of our Share Today Save Tomorrow Podcast being released! In Episode 26 – Communication is Key Anthony sits down with Darren Pauli, a cyber security awareness practitioner and freelance journalist who explains the importance of effective written communication within the digital world. During the AUSCERT2023 conference Darren gave an exploratory talk on the simple steps to become a faster, more effective written communicator. In today’s digital landscape, the influence of technology spans every industry, compelling an increasing number of non-technical personnel to grapple with cyber-related matters for their organisations. Consequently, it has become paramount for information security professionals to use clear, concise, and simple language to ensure they are effectively conveying messages. Yesterday, experts from the University of Queensland (UQ) published a paper to address the generalised lack of guidance on the ethical treatment of corporate data in higher education institutions. While the focus of this study is on the Higher Education sector, the principles discussed can be extended to other industries and organisations. This paper offers valuable observations and insights that can serve as a guide for ethical data practices, as currently no actionable framework currently exists within Australia. Our new Data Governance Principles and Practices course is led by one of the authors of this paper – Sasenka Abeysooriya. This training can assist your organisation in developing a successful data governance framework, by teaching best practices and real-world examples of data governance in action. By participating in this course, attendees are equipped with the fundamental skills and knowledge they need to accelerate the development of a successful data governance program in their organisation. For members’ convenience, we are currently offering in-person and online delivery of this course. Advisory: Qlik Sense Enterprise for Windows Remote Code Execution Vulnerabilities Date: 2023-08-29 Author: Praetorian [AUSCERT has notified affected members of this vulnerability where possible] Recently, we discovered two vulnerabilities which can be chained together to achieve unauthenticated remote code execution on Qlik Sense Enterprise. At the moment, we are waiting to publish technical details on the vulnerability to give impacted organizations time to update their systems and remediate the vulnerability. Praetorian has worked closely with Qlik to responsibly disclose these vulnerabilities, CVE-2023-41265 (HTTP Tunneling Vulnerability in Qlik Sense Enterprise for Windows) and CVE-2023-41266 (Path Traversal in Qlik Sense Enterprise for Windows). Cisco fixes 3 high-severity DoS flaws in NX-OS and FXOS software Date: 2023-08-29 Author: Security Affairs [Please see AUSCERT bulletin https://portal.auscert.org.au/bulletins/ESB-2023.4858] Cisco addressed three high-severity flaws in NX-OS and FXOS software that could cause denial-of-service (DoS) conditions. An attacker can exploit these three issues to cause a denial-of-service (DoS) condition.

This week's full moon symbolizes completion and strength, reflecting the importance of building a resilient cyber security strategy. We are thrilled to announce the release of the latest episode of ‘Share Today, Save Tomorrow’ – Episode 25 – What does the future hold. Join Anthony as he reunites with his old friend, the captivating and renowned Futurist, Dr Joseph Voros. An expert in the field of strategic foresight, Dr Voros provides valuable insights into the fascinating realm of preparing for uncertain futures. His work alongside governments worldwide has been instrumental in navigating the ever-evolving threat landscape of cyber security. Touching on the big trends in the future cybersecurity space, Dr Voros also comments on how artificial intelligence may pose more threats than benefits to us. Listen to this insightful conversation that explores how strategic thinking can shape a more secure and resilient future. As Artificial Intelligence (AI) Technology continues to advance and become increasingly sophisticated, the security risks associated with their use and potential for misuse also increase. The capabilities of AI open up new opportunities for hackers and malicious actors to create more targeted and authentic cyber attacks. Already we are starting to see chatbots trained specifically for malicious purposes such as phishing, social engineering, exploiting vulnerabilities and creating malware. The trend of using generative AI Chatbots is growing and the adoption rate is increasing as it can provide easy solutions for less capable threat actors or those wanting to expand operations to other regions and lack the language skills. A growing concern in the field of AI is the need for reforms and shared safety protocols. As AI systems become more advanced, experts are increasingly aware of the potential risks they pose to society and humanity. Just as the moon provides a guiding light in the darkness of the night, experts must remain vigilant and advocate for better safety protocols across the AI industry to ensure accountability and transparency.
