A Chrome Update You Shouldn’t Ignore – Here’s What to Know

What Happened?

Google recently discovered a security flaw in Chrome that hackers were already trying to exploit. It’s called a “zero-day vulnerability,” which just means the bad guys found it before Google could fix it.

The issue lies in something called a “type confusion” vulnerability.
In simple terms, it’s when the browser gets confused about what kind of data it’s working with—like mistaking a text box for a button. That confusion can be used by hackers to sneak in harmful code without you noticing.

This particular vulnerability affected Chrome versions before 138.0.7204.96. The good news? Google has already released a fix.

What We're Seeing

As of July 1, our security partners at Blackpoint Cyber have confirmed that this vulnerability is being actively exploited in the wild. That means threat actors are already taking advantage of this gap to launch attacks—typically by luring users to malicious websites.

Should You Be Worried?

Not if Chrome is updated.

Google acted quickly and patched the issue. If your Chrome is up to date, you're protected from this specific threat.

If you're unsure or don’t know how updates are handled at your business, it’s a good idea to check in with your IT support or give us a call.

What Should You Do Right Now?

1. Update Chrome
   Go to Chrome → click the three dots (top right) → Help → About Google Chrome → Let it update and restart.
2. Be cautious of unknown links and websites
   If something looks shady, don’t click it.
3. Ask your IT provider if you’re protected
   If you're a Four Winds IT client, reach out if you're unsure whether your systems are fully covered.

Some of our clients have chosen to include advanced cybersecurity tools like DNS filtering (which blocks malicious websites) or Blackpoint Cyber (which monitors for suspicious activity 24/7). These aren’t standard but are available for businesses looking for extra layers of protection.
