SMB Cyber Watch: F5 Breach Fallout, Adobe AEM Exploited, and Patch Tuesday Insights — Cybersecurity for Alberta Businesses
Welcome to this week’s Inks N Stuff IT Cyber Brief, your source for the latest developments in Managed IT Services and Cybersecurity Solutions in Alberta.
This week, several high-profile security incidents made headlines — from an F5 breach to newly exploited Adobe AEM vulnerabilities, and Microsoft’s most extensive Patch Tuesday this year.
Here’s what your business needs to know to stay secure and compliant.
🔒 F5 Breach and Supply Chain Risk
F5 Networks confirmed unauthorized access to its BIG-IP development environment, exposing sensitive code.
This highlights growing supply-chain risks for companies using load balancers or reverse proxies.
CISA issued an Emergency Directive urging immediate audits of F5 devices.
Organizations in Alberta relying on F5 technologies should review credentials, access logs, and firmware versions.

⚠️ Adobe AEM Critical Exploits
Adobe’s AEM platform was found to contain two critical vulnerabilities now actively exploited in the wild.
These flaws have been added to the CISA Known Exploited Vulnerabilities Catalog, emphasizing the urgency of patching immediately.

🪟 Microsoft October Patch Tuesday
This month’s update fixes 172 vulnerabilities (including several zero-days) and marks the end of scheduled security updates for Windows 10.
If your organization still runs Windows 10, plan for Extended Security Updates (ESU) or migrate to Windows 11 now.

Canadian SMEs Still Lagging Behind
A recent IBC survey found that many Canadian small businesses remain unprepared for cyberattacks — lacking policies, backup testing, and endpoint protection.
This is a reminder that Managed Cybersecurity Services can make the difference between downtime and resilience.

💡 Why This Matters for Alberta Businesses
For Alberta organizations, these incidents underscore why proactive IT management and cybersecurity are critical.
As cyber threats evolve, SMBs are increasingly targeted due to weaker defenses.
Regular patching, multi-factor authentication, and secure backups should be part of every business continuity plan.
If your company operates in Edmonton, Calgary, or surrounding areas, our IT Support Team can help implement these safeguards efficiently.
