Greetings, With less than 6 weeks remaining, we’re eagerly anticipating our return to the sunny Gold Coast, our favourite time of year! We have some exciting updates to our AUSCERT2024 program, including the addition of a workshop titled "Security in an Unmanaged Azure Environment: A Practical Example" lead by Greg Scheidel, a SANS Certified Instructor. This workshop will draw from the content of SANS SEC530: Defensible Security Architecture and Engineering, focusing on implementing Zero Trust for the Hybrid Enterprise. Limited spots available—act fast to secure your spot today! Visit our website for more details. This week marked a significant milestone in the cyber world! Nigel Phair, a Professor from Monash University, and renowned speaker who spoke at AUSCERT2023, contributes as a co-author in a new groundbreaking research study. After three years of dedicated research, an international team of researchers yesterday unveiled the first ever “World Cybercrime Index”. Developed through a collaborative effort between the University of Oxford, UNSW and funded by CRIMGOV, a European Union-supported project based at the University of Oxford and Sciences Pro, this index promises to reshape our understanding of global cybercrime dynamics. The World Cybercrime Index identifies the globe’s primary cybercrime hotspots by ranking the most prominent sources of cybercrime on a national level. The index reveals that the most significant criminal threats are concentrated in a handful of countries, with Russia leading the list, followed by Ukraine, China, the USA, Nigeria, and Romania. The research underlying the index will also shed light on the identities of cybercriminal offenders, potentially removing their veil of anonymity. Continuing to collect this data in the future will enable defenders and police agencies to monitor the emergence of any new cybercrime hotspots. Early interventions could potentially be implemented in at-risk countries before serious cybercrime problems develop. Government agencies and private enterprises tasked with combating cybercrime now have the opportunity to significantly improve their understanding of the scale of the issue within their own jurisdictions. Previously, knowledge of cybercriminal whereabouts was largely confined to specialist investigators, but now this information can be shared with the public, government, and business alike.

For over a decade, these awards have provided IT leaders and teams with an opportunity to gain recognition for their ambition, innovation, and the value they bring to government, industry, and the public. This year, the focus was on acknowledging both projects and the individuals behind Australia's best IT initiatives. AUSCERT is proud to support programs like these that highlight the hard work and important achievements of IT teams across our country! To top off a great week, the women of AUSCERT also attended a High Tea organised by the Australian Women in Security Network (AWSN), to commemorate International Women’s Day (IWD). The High Tea featured influential guest speakers, Tea Dietterich, CEO of 2M Language Services, and Jackie French, Director for the Faculty of Creative Arts at TAFE Queensland, who both discussed the concerns and issues that women often face when trying to excel in their careers. They spoke about this year's IWD theme, “Count her in: Invest in Women, Accelerate Progress,” and how it encapsulates our collective mission towards a more inclusive, innovative, and secure future for all. Women’s economic empowerment is essential if we hope to create a world where gender equality is not just a goal but a reality. When women are given equal opportunities to earn, learn, and lead, entire communities thrive. While progress has been made, women face significant obstacles to achieving equal participation in the economy. Without equal access to education, employment pathways, financial services, and literacy, how can we ever hope to reach gender equality? We must ensure that women are given equal opportunity to build capabilities and strengthen their capacity to learn, earn, and lead. To conclude, we would like to highlight the importance of empowering women and all staff through further education and training. We have recently released a whole new set of training courses specifically designed to enhance and empower staff with the essentials of cybersecurity. Check out our full list of upcoming training sessions here!

Greetings, The AUSCERT2024 program is now live! With the highest number of presentation submissions ever received, the selection committee faced the challenging task of curating a program that showcases the most relevant and impactful topics. Striving for diversity, the committee selected a wide array of subjects, ensuring a well-rounded and engaging program. If you haven't already, make sure to register as soon as possible to secure your spot! In recent news, the National Institute of Standards and Technology (NIST) has introduced version 2.0 of its cyber security framework (CSF), marking a significant update since its inception in 2014. This development is noteworthy as the framework now explicitly aims to assist all organisations, extending beyond critical infrastructure entities in managing and mitigating risks. The updated framework incorporates implementation examples, providing actionable steps to achieve various outcomes within different areas. Additionally, they have also released quick start guides to provide further direction and guidance to organisations wanting to achieve specific objectives. The updated NIST Framework places a new focus on governance. The new GOVERN function addresses the cyber security risk management strategy, expectations and policies that should be established, communicated and monitored. GOVERN essentially provides outcomes to inform what an organisation may do to achieve and prioritise the outcomes of the other five Functions within the framework (Identify, Protec, Detect, Respond & Recover). GOVERN also contains a new focus area on cyber security supply chain risk management. For member organisations seeking additional support in governance, we recommend registering for our new training course, "Data Governance Principles and Practices." In this course, our expert practitioners delve into the key components of a successful data governance framework, utilizing real-world examples to illustrate best practices. The training is designed to provide attendees with fundamental skills and knowledge essential for expediting the establishment of a successful data governance program within their organisation. Participants will also learn practices and methodologies applicable to various initiatives, including stakeholder management, identification of pain points and the development of related objectives ultimately leading to the creation of a strategy on a page.

Greetings, AUSCERT has detected a rise in Critical MSINs being sent to members. These proactive alerts are flagged for urgent attention to mitigate potential high-priority risks, particularly when AUSCERT identifies exploitation of 0-day vulnerabilities. CISA, along with its five-eye country partners, has issued a joint advisory on 'Identifying and Mitigating Living Off the Land Techniques' (LOLT). Notably, cyber threat actors, including state-sponsored actors from the People’s Republic of China and the Russian Federation, have been observed employing LOLT to compromise and maintain persistent access to critical infrastructure organisations. This joint guide is released for network defenders and threat hunters, addressing the increasing prevalence of LOLT techniques in the broader cyber threat landscape. Understanding and countering these techniques is crucial for enhancing cybersecurity posture and mitigating risks from sophisticated adversaries. In other recent developments, the Pall Mall Process declaration between the UK and France marks a crucial stride in addressing the proliferation and irresponsible use of commercial cyber intrusion capabilities. Cyber proliferation involves the intentional or unintentional transfer of cyber capabilities among actors for network or device exploitation or attack purposes. The Pall Mall Process declaration is an innovative international initiative aimed at exploring policy options and new practices to counter this shared threat. The NCSC’s recent blog delves into what this process signifies for the future. Take a moment to read and stay informed, you can then “advance to GO”. Are you aware of Australia's Online Safety Laws? While employing measures like secure passphrases and two-factor authentication provides a strong defence against bad actors, it's equally important to report illegal and violent content online. To learn more, visit esafety.gov.au, these laws have your back! Business risks are also important. The AUSCERT Cyber Security Risk Management course is designed to provide participants with the confidence to perform a risk assessment of cyber security risks, and the ability to rate, assess, and report business risks. Calibrating cyber security as business risks rather than just technical vulnerability severity readily facilitates business leader buy-in. Register today!. Here are some highlights from this week’s cyber security news, including the significant law enforcement takeover of the prolific multinational ransomware syndicate behind LockBit.
