AUSCERT Week in Review for 12th April 2024

12 Apr 2024

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.
