Greetings, Another week is coming to a close, and what an eventful week it has been! Some of our team members travelled to Sydney to reconnect with our valued members and attended the iTnews 2024 Benchmark Awards. 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, 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!.

Greetings, The ACSC has developed a valuable single reporting tool to help you determine which Australian regulations apply to your organisation, as well as specifying when and to whom you need to report a cyber breach. First highlighted in the government’s Australian Cyber Security Strategy 2023-2030, the swift availability of this resource is notable. Its significance lies in simplifying the process and will undoubtedly have a positive impact on our community. The federal government launched the Cyber Security Legislative Reforms consultation paper late last year to gather views on new legislative initiatives and proposed amendments to the Security of Critical Infrastructure Act 2018. This consultation paper outlines reforms that were part of the Australian Cyber Security Strategy action plan and covers nine areas that are worthy of a read. One being Ransomware reporting obligations which is one of the fastest growing types of cybercrime. The government is proposing that reporting ransomware incidents should become a mandatory, no-fault, no-liability obligation for businesses. The National Office of Cyber Security’s recent review of the HWL Ebsworth cyber incident demonstrates various lessons, with one significant takeaway being the company’s close collaboration with government agencies in effectively handling the incident. Therefore, the government is considering introducing a Cyber Incident Review Board co-designed with the industry to share the lessons learned from cyber incidents with businesses and the wider public. The HWL Ebsworth breach involved the exfiltration of 4TB of data (2.2 million files), including sensitive information from 62 Australian government entities, major banks, airlines, and other multinational businesses.

Greetings, This week, AUSCERT has been busy finalising our member meet-up schedule for 2024! Keep an eye out for invitations coming out soon for a catch-up in your local area! They offer invaluable moments of sharing industry expertise, knowledge sharing, and the chance to connect with old friends while making new ones within the cyber security industry. In cyber news this week, customers of some of Australia’s well-known brands including Dan Murphy’s, Binge, Guzman y Gomez, and Event Cinemas have fallen victim to a coordinated credential stuffing attack, affecting an estimated 15,000 customers. Scammers acquired stolen login details and are exploiting online accounts to conduct fraudulent transactions, accumulating thousands in online purchases. Prime Minister Anthony Albanese emphasized the critical importance of cyber awareness and security during the recent wave of cybercrimes, highlighting the significant threat to Australia and its economic security. A credential stuffing attack like this one involves the use of large sets of username and password combinations obtained from previous data breaches to gain unauthorised access to user accounts on various online platforms. Attackers use automated tools or scripts to test stolen credentials to gain access into different websites or services. If the login attempt is successful, the attacker gains unauthorised access to the user’s account. Attackers may then exploit the compromised account for various malicious activities such as stealing personal information, making unauthorised transactions or launching further attacks. Here are a few helpful tips to protect against credential stuffing attacks: • Reuse of Credentials: – While using strong passwords, passphrases, and password managers is crucial, it's equally important to avoid using the same credentials across multiple platforms. In the event of a data breach on one site or any alternative compromise, your username and password could be exposed, leaving you susceptible to credential-stuffing attacks on other sites. • Enable Multi-Factor Authentication (MFA): – If possible, enabling MFA adds an additional layer of security by requiring a second form of verification along with password. • Regularly Update Passwords: – Users should regularly update their passwords to reduce the risk associated with compromised credentials. • Rate Limiting & CAPTCHA: – Online platforms can implement rate limiting to detect and prevent multiple logins. Additionally CAPTCHA challenges can help stop automated attempts. The above steps are simple ways to enhance your cyber security posture for 2024!

We stand prepared to embrace new challenges, learn from the past and propel ourselves forward into an era of growth and prosperity. Just as individuals set resolutions for the new year to pursue good health and fortune, businesses must also create resolutions for improved cybersecurity practices. In our rapidly evolving digital ecosystem, the year ahead promises both ground-breaking strides and the continuous evolution of technology advancements. As organisations gear up to defend against ever-more-sophisticated cyber threats, the role of artificial intelligence and machine learning has elevated threats to new heights. Collaboration is a cornerstone in the cyber realm, as information sharing among industries, governments, and security communities becomes integral to staying one step ahead of cyber threats. The exchange of threat intelligence, best practices and incident response strategies becomes integral to creating a resilient defence ecosystem. The start of 2024 emphasizes the need for a united front against cyber-attacks, as threats become increasingly borderless and interconnected. Therefore our theme for AUSCERT2024 is “Pay it Forward,” as it highlights the importance of passing it forward by demonstrating how shared knowledge and collaboration can create a ripple effect, strengthening the entire field of cyber security. Cyber Conferences serve as an invaluable platform to cultivate new relationships, establish improved communication channels, and facilitate information sharing across organisations and the broader community. Join us at AUSCERT2024 and discover the power of amplifying your impact in the realm of cyber security. The theme for this year highlights the significant influence that everyone’s action can carry within the broader cyber community. We are already hard at work, developing a ground-breaking program of tutorials and presentations, so keep your eyes peeled for more updates. Please note Call for Presentations closes on the 29th of January. We encourage you to submit as soon as possible!
