👀 When Your Browser Becomes the Spy: New Chrome Exploit Exposed

‍

Your browser might be watching you—literally.

‍

Security researcher mr.d0x just revealed a terrifyingly simple method to turn Google Chrome (and other Chromium-based browsers like Edge, Brave, and Opera) into full-blown spyware. No malware downloads. No user clicks. Just a few command-line flags.

Think screen recordings, mic audio, and webcam access—all without your knowledge.

How It Works

Using a PowerShell script, an attacker with access to your system can:

• Launch a headless or invisible browser window
• Auto-enable screen sharing using --auto-select-desktop-capture-source=Entire
• Use JavaScript to take screenshots every 3 seconds
• Auto-capture camera and mic feeds using --auto-accept-camera-and-microphone-capture
• Exfiltrate all of this to a remote server in real time

No browser extensions. No suspicious software. Just legitimate tools misused for espionage.

Why It Matters for SMBs, Law Firms, Schools, and Healthcare

If your endpoints aren’t tightly controlled, a single compromised machine could leak:

• Patient health info (violating HIPAA)
• Client legal files
• Student data under FERPA
• Internal business IP, financials, or communications

This type of attack is stealthy, remote-controlled, and bypasses many endpoint detection systems because it uses native system tools.

How to Defend Against Browser-Based Spyware

At Gigabit Systems, we help organizations defend against advanced threats like this. Here’s what we recommend:

✅ Monitor for unusual command-line flag use with EDR tools

✅ Block PowerShell for non-admin users

✅ Restrict outbound connections to untrusted domains

✅ Disable camera/mic access at the OS level where unnecessary

✅ Educate staff about social engineering tactics like fake CAPTCHA sites or fake support pop-ups

And most importantly—audit your browser usage policies. Browsers aren’t just for surfing anymore—they’re a massive attack surface.
