Urgent: Chrome Browser and Router Security Flaws Could Let Hackers In

A serious security flaw has been found in the Chrome web browser and some internet routers that could allow hackers to take control remotely. This matters because many small businesses use Chrome and routers daily, and these weaknesses could let attackers access sensitive information or disrupt services.

08 September 2026

1. What is being reported?

Researchers have discovered a 'zero-day' vulnerability in Chrome, meaning it was unknown before being actively exploited. Additionally, some routers are vulnerable to 'hijacking' attacks, where hackers can change settings or intercept data. These issues could let attackers run harmful code on your devices without your knowledge.

2. What this means in plain English

If your business uses Chrome or certain routers, hackers might be able to break in remotely, steal information, or cause your internet to stop working properly. This could lead to data loss, privacy breaches, or downtime, which can be costly and damaging to your reputation.

3. Could this affect a small business?

Small businesses using the Chrome browser and common routers connected to the internet could be affected. Those who do not use Chrome or have routers managed by their IT provider may be less at risk, but it’s best to check.

4. What to do now

  • Ensure your Chrome browser is updated to the latest version immediately.
  • Check with your router manufacturer or IT provider for any security updates or patches.
  • Restart your router regularly and change default passwords to strong, unique ones.
  • Be cautious of unexpected changes in your internet connection or browser behaviour and report concerns promptly.

5. Ask your IT provider

Can you confirm if our Chrome browsers and internet routers are updated and protected against the recent zero-day and router hijacking vulnerabilities?

6. Bottom line

Keep your browser and router software up to date to protect your business from hackers exploiting these new security flaws.
