Millions of Google Chrome users may be at risk after India’s cybersecurity agency issued a major warning regarding multiple high-risk vulnerabilities discovered in the desktop version of the popular browser.

The alert was released by Indian Computer Emergency Response Team, the cybersecurity body operating under India’s Ministry of Electronics and Information Technology. According to the agency, several serious security flaws have been identified in Google Chrome that could allow hackers to steal sensitive information, execute malicious code remotely, or even crash users’ systems.

The warning applies to Chrome users on:

• Windows
• macOS
• Linux

Cybersecurity experts are now strongly advising users to update their browsers immediately to avoid potential attacks.

CERT-In Warns About Critical Chrome Vulnerabilities

CERT-In stated that multiple security loopholes have been detected in older desktop versions of Google Chrome.

These vulnerabilities reportedly exist in several important browser components including:

• WebRTC
• GPU systems
• QUIC protocol
• XR features
• Other internal browser frameworks

Hackers may potentially exploit these weaknesses to bypass security protections and gain unauthorized access to devices.

According to the warning, attackers could:

• Execute harmful code remotely
• Steal private data
• Install malware
• Trigger browser crashes
• Cause Denial-of-Service (DoS) conditions

The agency emphasized that users running outdated versions of Chrome are particularly vulnerable.

Which Chrome Versions Are at Risk?

CERT-In specifically highlighted older browser versions as the most dangerous.

Affected versions reportedly include:

For Linux Users

• Chrome versions older than 148.0.7778.178

For Windows and macOS Users

• Chrome versions older than 148.0.7778.178 or 148.0.7778.179

Users running these versions are strongly advised to install the latest security updates immediately.

How Hackers Could Exploit the Vulnerabilities

Cybercriminals often exploit browser vulnerabilities through malicious websites, fake advertisements, or phishing links.

According to cybersecurity experts, attackers may trick users into:

• Clicking suspicious links
• Visiting fake websites
• Downloading harmful files
• Opening manipulated web pages

Once a vulnerable Chrome browser accesses such content, hackers may be able to inject malicious code into the system.

This can potentially allow attackers to:

• Monitor activity
• Steal passwords
• Access banking information
• Capture login credentials
• Install spyware or ransomware

In severe cases, attackers may even gain deeper control over the affected device.

Why Browser Security Is Extremely Important Today

Web browsers have become one of the most important gateways to personal and financial information.

People use browsers daily for:

• Internet banking
• Online shopping
• Email access
• Social media
• Office work
• Cloud storage
• Digital payments

As a result, browsers are one of the biggest targets for cybercriminals worldwide.

Even a small security flaw inside a browser can expose large amounts of sensitive data if left unpatched.

What Users Should Do Immediately

Cybersecurity experts recommend several immediate steps for Chrome users.

Update Google Chrome Immediately

Users should check whether they are running the latest browser version.

To update Chrome:

1. Open Chrome
2. Click the three-dot menu in the top-right corner
3. Go to “Help”
4. Select “About Google Chrome”
5. Chrome will automatically search for updates
6. Restart the browser after updating

Installing the latest version is the most important step to protect against known vulnerabilities.

Avoid Clicking Suspicious Links

Users should remain cautious when receiving:

• Unknown emails
• Random pop-up messages
• Suspicious advertisements
• Unverified download links

Many cyberattacks begin through phishing attempts designed to trick users into visiting harmful websites.

Keep Operating Systems Updated

Browser security also depends partly on updated operating systems.

Users should regularly install:

• Windows updates
• macOS security patches
• Linux security updates

These updates often contain additional protections against browser-based attacks.

Use Trusted Antivirus Protection

Reliable antivirus software can help detect:

• Malicious downloads
• Harmful scripts
• Suspicious browser behavior
• Malware attempts

Security software adds another important protection layer alongside browser updates.

Chrome Vulnerabilities Often Become Major Cybersecurity Targets

Google Chrome remains the world’s most widely used web browser, which also makes it one of the biggest targets for hackers.

Because billions of users depend on Chrome daily, attackers frequently search for:

• Zero-day vulnerabilities
• Browser exploits
• Remote code execution flaws
• Data theft opportunities

Technology companies and cybersecurity agencies regularly release emergency updates to patch these weaknesses before attackers can exploit them widely.

Google Frequently Releases Security Fixes

Google continuously rolls out browser security updates to fix newly discovered vulnerabilities.

Many updates happen automatically in the background, but users sometimes delay restarting the browser, leaving systems temporarily exposed.

Cybersecurity experts recommend:

• Restarting Chrome regularly
• Avoiding outdated browser versions
• Enabling automatic updates whenever possible

These small steps can dramatically improve online safety.

Simple Negligence Can Lead to Big Security Risks

Many users ignore browser update notifications because updates appear inconvenient or time-consuming.

However, outdated browsers often become the easiest entry points for cyberattacks.

A single malicious website or phishing link may be enough to compromise an unpatched system.

As cyber threats continue growing globally, experts warn that regularly updating browsers is no longer optional — it is one of the most important digital safety habits every internet user should follow.
