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.

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.

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.

Greetings, This week, the AUSCERT analyst team successfully completed the annual drill hosted by the Asia Pacific Computer Emergency Response Team (APCERT). The drill tests the capabilities of leading Computer Security Incident Response Teams (CSIRTS) in the Asia Pacific region. This year 24 teams participated from 21 countries, being tested on their abilities to interact and collaborate locally and internationally. The aim of the exercise was to strengthen collaboration amongst the different constituencies, enhance communication and develop technical capabilities and quality of incident response to ensure security and safety. The theme of this year’s APCERT Drill was “Digital Supply Chain Redemption” which reflects real incidents and issues that exist today. We are honoured to be part of such an incredible drill as it provides an opportunity to strengthen our relationship with local and international partners, as well as enhancing our team’s knowledge and skills when dealing with complex global incidents. Recently the National Institute of Standards (NIST) released a new draft update to its globally used Cybersecurity Framework (CSF). First released in 2014, the CSF has been updated to reflect the community’s feedback and current usage patterns. The Framework provides high-level guidance, including a common language and a systematic methodology for managing cybersecurity risk across sectors and aiding communication between technical and nontechnical staff. This includes initiatives that can be incorporated into cybersecurity programs and tailored to meet organisational objectives. One key update to the Framework has been adding an extra pillar for ‘Govern’. The Govern function is designed to establish and monitor an organization’s cyber security risk management strategy, expectations and policy. The public draft is available via the NIST website or you can click here to read the full document. It provides guidance on implementing the CSF and tailoring it for different organisational sectors. NIST does not plan to release another draft of CSF 2.0 for comment. The final CSF 2.0 is to be published in early 2024. Finally, for our South-East Queensland readers, we would like to inform you that SANS will be holding their highly anticipated cutting-edge information and hands-on in-person training event in Brisbane from October 9 -14, 2023. SANS Brisbane 2023 features three of SANS most popular courses which aim to provide cyber security professionals with the tools and knowledge required to combat ever-evolving cyber threats.

Greetings, This week, the moon made a stunning appearance, captivating the world with its extraordinary beauty. Larger and brighter than ever, the majestic supermoon illuminated the night sky, drawing people’s eyes upward in awe. Its radiant glow was visible to all, uniting people from different corners of the globe, mesmerized by its allure. Just as the moon goes through its various phases, cyber security operates on a layered defence approach, encompassing detection, prevention, response and foresight planning. 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. Second Ivanti EPMM Zero-Day Vulnerability Exploited in Targeted Attacks Date: 2023-07-31 Author: Security Week [AUSCERT has directly notified affected members about this vulnerability where possible] Ivanti has warned customers about a second zero-day vulnerability in its Endpoint Manager Mobile (EPMM) product that has been exploited in targeted attacks. Further investigation by cybersecurity firm Mnemonic revealed the existence of CVE-2023-3508, a high-severity flaw that allows an authenticated attacker with administrator privileges to remotely write arbitrary files to the server.

Threat actors abuse Google AMP for evasive phishing attacks Date: 2023-08-01 Author: Bleeping Computer Security researchers are warning of increased phishing activity that abuses Google Accelerated Mobile Pages (AMP) to bypass email security measures and get to inboxes of enterprise employees. The idea behind using Google AMP URLs embedded in phishing emails is to make sure that email protection technology does not flag messages as malicious or suspicious due to Google’s good reputation. The AMP URLs trigger a redirection to a malicious phishing site, and this additional step also adds an analysis-disrupting layer. Relying on CVSS alone is risky for vulnerability management Date: 2023-07-31 Author: Help Net Security A vulnerability management strategy that relies solely on CVSS for vulnerability prioritization is proving to be insufficient at best, according to Rezilion. In fact, relying solely on a CVSS severity score to assess the risk of individual vulnerabilities was shown to be equivalent to randomly selecting vulnerabilities for remediation.

Greetings, Barbie Mania has introduced a concerning new trend of cyber-related attacks worldwide. Leveraging the distraction caused by the hype, criminals are taking advantage of this opportunity to launch attacks on unsuspecting individuals. Related attacks have risen since the promotion and release of the movie with the U.S. taking the brunt of the attacks, however other countries such as the UK and Australia are also being impacted. Criminals are exploiting this trend to trick people into clicking malicious links, harmful files or providing sensitive information leading to data breaches and financial losses. Blinded by excitement many people are acting impulsively, thus making them susceptible to these deceptive methods. Social engineering cyber attacks like the Barbie trend are becoming increasingly sophisticated and pervasive. Criminals have recognized the power of using popular trends and emotional triggers as bait to manipulate and deceive people. Exploiting emotions and creating a sense of urgency or excitement can be a trigger for individuals to divulge their sensitive information. CTO of McAfee, Steve Grobman, explained that this is not a new trend and criminals will look for any opportunity to make their scam more attractive and believable, often leveraging popular and well-publicized events to trick users into clicking on malicious links. Social engineering attacks are all about the psychology of persuasion, targeting the mind and heart, with the main aim being to gain the trust of the target, encourage them to lower their guard and engage in unsafe actions. Here are a few tips & tricks to avoid scams like these: Stick with reliable suppliers, brands or networks. If you’re unfamiliar with the brand, it’s best to investigate the source of the content. Use your judgement – and don’t let emotions cloud your judgement! If an offer seems too good to be true.. it often is! It is essential to be cautious of unexpected requests, unsolicited emails or messages. Do your research – before giving away your sensitive details or financial information research the organisation and ensure they are a trustworthy source. Members – contact us! If you're an AUSCERT member don't forget you can always contact us for support. This deceptive tactic serves as a stark reminder of the ever-evolving methods cybercriminals employ to deceive and victimize people. By staying informed, employing strong security practices and being sceptical of suspicious communications we can better protect ourselves and our data from falling into the wrong hands.

Greetings, It’s that time of year again! The BDO and AUSCERT 2022 Cyber Security Results are in! For the seventh year in a row, organisations across Australia and New Zealand were surveyed to identify the challenges and threats experienced in 2022 as well as what organisational leaders have prioritised to protect key assets and infrastructure. The findings from the report give a comprehensive overview of the present cyber security landscape in Australia and New Zealand. It delves into recent trends in cyber threats, their impact and the measures being implemented to mitigate these risks. In the ever-evolving digital landscape, the significance of implementing strong cybersecurity measures has escalated. In 2022 BDO & AUSCERT reported a growing concern over data breaches, affecting individuals and high-profile organisations. The continuously evolving cyber threat landscape and increasing sophistication of attacks has emphasized the necessity for organisations to prioritise the development of cyber resilience. Here are a few key themes that the report revealed. 1) Senior leadership is key to driving cyber security resilience The report revealed the importance for Executive Leadership teams to take a more active role in Cyber governance in addition to being aware of the cyber risks within their organisations. The data collected indicated that although there had been a significant increase in attacks – concerningly there was a decline in senior leadership emphasis. Establishing effective leadership is crucial in fostering the adoption and implementation of policies and practices related to cyber security resilience. 2) The rapidly evolving cyber threat landscape Rapid technology advancements have triggered the growth and increased sophistication of threats resulting in greater impacts during incidents. Data suggests cyber criminals are advancing at unprecedented levels relentlessly pursuing new methods to locate and exploit vulnerabilities. However reports indicate a concerning decline in organisations investing in the essential resources required to effectively detect and respond to incidents. Neglecting to allocate sufficient resources to cyber security can result in an increased vulnerability to attacks. 3) Importance of resilience In this current landscape it is crucial for us all to realise we are all vulnerable to an attack at any time. Cyber resilience involves accepting this and planning accordingly for the different incidents that may occur, what assets may be targeted, how quickly we can identify the incident and how we respond. If you’re interested in delving deeper into these topics or eager to gain further insights from the 2022 report, we invite you to download the complete report now!

How kids pay the price for ransomware attacks on education Date: 2023-07-07 Author: Malwarebytes Modern ransomware attacks are as much about stealing data and threatening to leak it as they are about encrypting data. Which means that when a school or hospital is attacked, it's often students' and patients' data that's leaked if the ransom demand isn't met. We have to wonder how greedy any person would need to be to show such a blatant disregard for how painful sharing that kind of information can be. In our recent report on the state of ransomware in education we saw an 84% increase in known attacks on the education sector. Storm-0978 attacks reveal financial and espionage motives Date: 2023-07-11 Author: Microsoft Corporation Microsoft has identified a phishing campaign conducted by the threat actor tracked as Storm-0978 targeting defense and government entities in Europe and North America.

Greetings, Many hackers employ the principles of persuasion to tell you lies and play on your vulnerabilities as a human being to obtain your sensitive information. In our latest episode of ‘Share Today Save Tomorrow’ Anthony sits down with Rachel Tobac, CEO of Social Proof Security and explores human vulnerabilities – Episode 24: People, People, People, Process and Technology.. Rachel explains the importance of verifying the authenticity of any request by employing different tools and methods to justify the credentials of the sender and searching for hidden agendas. In the spirit of full disclosure giant global corporation Microsoft has been heavily targeted by a hacktivist group ‘Anonymous Sudan’. However, Microsoft has chosen not to disclose specific details of these incidents publicly. Earlier this week, Microsoft denied public claims made by the group regarding a data breach which allegedly resulted in 30 million customer account details being compromised. Anonymous Sudan posted a sample of the stolen data online offering it for sale, yet Microsoft denied the validity of these allegations. Over a month ago Microsoft experienced a distributed denial of service (DDoS) attack orchestrated by the same group and resulted in the disruption of several of its services.. At the time Microsoft did not provide specific information regarding the attacks, prompting Anonymous Sudan to publicly call them out for their alleged dishonesty and issue threats to teach them a lesson via a statement on their public Telegram channel.. It’s important to note the situation is still developing and we are awaiting further updates from Microsoft as the investigation progresses. Only the truth will be able to determine the best possible solution for all the parties implicated. By encouraging open collaboration and information exchange, we strive to collectively strengthen our defences against cyber threats. We are currently seeking a skilled and driven Senior Security Systems Administrator to join our team. The due date to apply has been extended to Monday 10th July , so if you or anyone you know are interested in joining our team, please apply soon.

Who’s Behind the DomainNetworks Snail Mail Scam? Date: 2023-07-03 Author: Krebs on Security If you’ve ever owned a domain name, the chances are good that at some point you’ve received a snail mail letter which appears to be a bill for a domain or website-related services. In reality, these misleading missives try to trick people into paying for useless services they never ordered, don’t need, and probably will never receive. Here’s a look at the most recent incarnation of this scam — DomainNetworks — and some clues about who may be behind it. The DomainNetworks mailer may reference a domain that is or was at one point registered to your name and address. 300,000+ Fortinet firewalls vulnerable to critical FortiOS RCE bug Date: 2023-07-03 Author: Bleeping Computer [AUSCERT has identified the impacted members (where possible) and contacted them via MSIN] Hundreds of thousands of FortiGate firewalls are vulnerable to a critical security issue identified as CVE-2023-27997, almost a month after Fortinet released an update that addresses the problem.
