Cybersecurity Alert: Government Issues High-Risk Warning for Chrome and Mozilla Users in India

Urgent Warning for Browser Users: Critical Security Flaws Found — Update Immediately to Stay Safe!

India’s national cybersecurity agency, the Computer Emergency Response Team (CERT-In), has issued a high-severity security alert for users of Google Chrome and Mozilla Firefox. According to the advisory, multiple critical vulnerabilities have been detected that could allow hackers to steal personal data, crash systems, or gain full control over affected devices.

These newly discovered flaws impact several versions of both browsers. CERT-In has strongly advised users to update their browsers immediately to prevent any possible cyberattacks.

⚠️ What Makes This Threat Serious

The vulnerabilities found in Google Chrome are particularly risky for users running Chrome OS or ChromeOS Flex. The issue stems from a heap buffer overflow in core browser services such as Video, Sync, and WebGPU.

In simpler terms, this means that a remote hacker could execute malicious code simply by tricking you into visiting a compromised website. A single click on a seemingly harmless link could be enough to give cybercriminals access to your browser, allowing them to steal sensitive information or damage your system.

Similarly, the security loopholes in Mozilla Firefox affect users running its base browser, Extended Support Release (ESR) versions, and even the Thunderbird email client. Experts warn that hackers could exploit these flaws to perform unauthorized actions, putting user privacy and data at significant risk.

🌐 How Hackers Can Attack Through the Web

Hackers can design malicious web pages that automatically trigger these vulnerabilities once opened in the browser. Since Chrome and Firefox are used by millions of people in India for everyday tasks like online shopping, banking, and social networking, the potential impact is widespread.

Cybersecurity experts explain that these attacks are often silent and invisible, meaning users might not realize their system has been compromised until it’s too late.

🛡️ What You Should Do Immediately

If you use Google Chrome or Mozilla Firefox, here are the urgent steps you should take to protect your data and device:

Update your browser immediately:

• For Chrome users: Go to Settings → Help → About Google Chrome to check for updates.

• For Firefox users: Open Menu → Help → About Firefox to install the latest version.

Enable auto-updates:
Turn on automatic updates so future security patches are applied without delay.

Avoid suspicious links and websites:
Do not click on unknown or unverified links shared via email, SMS, or social media.

Restart your system after updates:
Once updates are installed, restart your browser and computer to ensure the changes take effect.

Use antivirus protection:
Keep a trusted antivirus program running and perform regular scans to detect any hidden threats.

💡 Expert Advice

Cybersecurity professionals emphasize that browser updates are not just performance improvements — they’re critical for online safety. Even a few days of delay can expose users to malware, phishing, and ransomware attacks.

“Browser vulnerabilities are like open doors for hackers,” warns a cybersecurity analyst. “The fastest way to protect yourself is to update as soon as an alert is issued.”

✅ Final Takeaway

If you haven’t updated your browser recently, do it right now. With cyber threats growing every day, staying alert and keeping your software up to date is the simplest yet most effective defense.

A single update today could save you from a major cyberattack tomorrow.
