Week in review

Greetings,

R U OK is encouraging everyone to ask "R U OK?" any day, because life happens every day. This reminder comes as 72% of Australians report experiencing elevated levels of distress. Each year, R U OK Day serves as a powerful reminder of the importance of checking in on others' well-being and actively listening to their concerns. Often, those facing challenges may not openly express their feelings, and a simple, empathetic conversation can make a huge difference. Asking "Are you okay?" and genuinely listening can offer emotional support and show someone they are not alone in their struggles.

Meaningful connection and open dialogue about mental health help build a supportive and compassionate community. Prioritising mental health reduces stigma and creates an environment where people feel comfortable sharing their feelings and seeking help. It's a reminder that small acts of kindness and genuine concern can profoundly impact someone's life. For a range of free resources for your workplace, home or community, visit the R U OK? Day website.

AUSCERT has always been a strong advocate for mental health support and services, actively implementing more mental health initiatives in the workplace and at our conferences. At AUSCERT2024, we again provided an onsite psychologist for attendees, offering the opportunity to discuss anything from mental wellbeing to life coaching. This year, we introduced mindfulness walks in the mornings that allowed delegates to start the day with a peaceful, serene stroll along the beach, and also introduced a dopamine hit of puppy pats and cuddles throughout the day – this was extremely popular!

This week, Microsoft addressed and patched critical zero-day vulnerabilities as part of its monthly update.

The first vulnerability, identified as CVE-2024-38217, affected Smart App Control and SmartScreen in Windows. This vulnerability allowed malicious files to bypass crucial security warnings and execute without raising any alarms. It appears to have been actively exploited by hackers for at least six years, with numerous samples detected on VirusTotal since 2018!

The second vulnerability resided within the Windows Servicing Stack and allowed remote code execution (RCE). Identified as CVE-2024-43491, the cause of this vulnerability was a flaw in the Servicing Stack that essentially rolled back security fixes for optional components in Windows 10 version 1507. This left systems exposed to previously mitigated threats by removing prior security patches installed between March and August 2024.

This is a timely reminder to always remain vigilant with patching systems regularly in your environment to mitigate and protect against such critical zero-day vulnerabilities. Please see this AUSCERT bulletin for more information on the above Microsoft vulnerabilities.
