Windows Zero-Day: Ransomware Groups Exploiting a Critical Driver Vulnerability Right Now

Who's affected:Everyone on WindowsSmall BusinessHome Users

A critical flaw in a core Windows driver is actively exploited by ransomware groups. Attackers can gain full control of your PC — files, emails, and bank logins all at risk. Microsoft has released an emergency patch. This requires action today, not tomorrow.

What should I do?
Open Settings → Windows Update and install all pending updates — specifically KB5042314. Restart your computer. If you manage a business with multiple PCs, call us — we can push the patch to all devices remotely.

How does this page work?

The Tech Radar is updated by the Onside IT team in Sydney, usually several times a week. When something affects our clients — a scam doing the rounds, a critical patch, a service outage, or a deadline coming up — we write it up in plain English so you know exactly what to do.

The live service status panel automatically checks Atlassian, Slack, Zoom, GitHub and Cloudflare every 5 minutes. Microsoft 365, AWS, Google Workspace and NBN are linked to their official status pages.

If something urgent is affecting you and it's not here yet, give us a call. We're happy to help.
