//Week in review - 2 Feb 2024
Greetings,
What better way to kickstart your cybersecurity goals this year by improving your knowledge with the most relevant strategies? This week, our team has been busy creating a schedule of training courses for our members to register for in 2024! Remember, the best way to get ahead of threats and attacks is to have the most relevant education and training in effective strategies to successfully mitigate cyber risks. Head to our Training page for more information on courses you can register for! Alternatively, contact us for more information at training@auscert.org.au.
During a big week filled with security patches and updates, various vendors and platforms released fixes for different vulnerabilities. AUSCERT’s team of expert analysts worked diligently to issue bulletins, ensuring members were informed of the latest information. We specialise in vulnerability research, delivering consistently formatted bulletins across major platforms and vendors to streamline security patching. Once a patch for a vulnerability is publicly released by a vendor, it is recommended to apply it as soon as possible, as malicious actors are expected to start developing code to exploit it.
Although with an abundance of updates flooding in daily, we understand the importance of prioritising effectively to ensure your resources are adequately utilised. Our security bulletins provide concise summaries, enabling quick comprehension of essential information, severity determination, and prioritisation of organisational patching efforts. Each vulnerability comes with a recommended resolution, including patching, upgrading, and mitigation suggestions. AUSCERT publishes Security Bulletins each business day, curating and checking content to ensure up-to-date information for our members.
Members can also subscribe to the Daily Bulletins Digest, summarising all the Security Bulletins published throughout the day in a single email. If you would like to update your organisational Security Bulletins to the Daily Bulletins Digest simply email – membership@auscert.org.au.
By maintaining clear and streamlined patch management processes and procedures, organisations can position themselves to act swiftly upon vulnerability announcements and patch releases. Strategy minimises the attack surface of systems, leading to an enhancement in your overall security posture.

A year later, they updated maturity levels to the Essential Eight, their comprehensive guide for businesses trying to protect themselves against cyberattacks. In 2022, they appointed Clare O’Neil as their first-ever dedicated Minister for Cyber Security.
Ransomware payments drop to record low as victims refuse to pay
Date: 2024-01-29
Author: Bleeping Computer
The number of ransomware victims paying ransom demands has dropped to a record low of 29% in the final quarter of 2023, according to ransomware negotiation firm Coveware.
This trend became apparent in mid-2021 when the payment rate dropped to 46% after previously being 85% at the start of 2019.
According to Coveware, the reason for this continual drop is multifaceted, including better preparedness by organizations, a lack of trust towards cybercriminals promising not to publish stolen data, and legal pressure in some regions where paying a ransom is illegal.
