If cybersecurity were a game, software updates would be the cheat code. Yet many users delay them, leaving systems exposed. At Envision IT, we call updates “digital hygiene”—simple, routine, and essential.
Why Updates Matter: Updates patch known vulnerabilities. Attackers often exploit outdated software—sometimes within hours of a flaw being disclosed.
Behind the Breach: Microsoft SharePoint “ToolShell” Exploits (2025)
In 2025, attackers exploited a known vulnerability—ToolShell—in unpatched on-premises Microsoft SharePoint servers. Despite Microsoft having released patches, many organizations delayed applying them. As a result, over 400 systems were compromised, including those belonging to U.S. government agencies and the Department of Energy.
This breach is a stark reminder that delaying updates can have national-level consequences. The fix was available—but unpatched systems remained vulnerable, giving attackers an easy in.
What to Update:
- Operating systems
- Browsers and plugins
- Mobile apps
- Security tools
Make It Easy:
- Enable automatic updates where possible.
- Schedule update windows to minimize disruption.
- Use centralized patch management tools.
For IT Leaders: Implement patch management policies. Use tools like WSUS or Intune. Track update compliance and prioritize critical patches to help prevent major incidents. Real-time dashboards and automation streamline the process.
Updating software is one of the easiest cybersecurity wins. Don’t ignore it—embrace it.
