In 2025, Google Chrome warns users about a surge in dangerous extensions capable of surveillance, data theft, and malware injection. For Indian internet users—whether students, professionals, or casual browsers—it’s critical to stay alert and informed. This article explores the risk of surveillance by dangerous extensions in 2025, providing actionable steps to protect your privacy and security.
📈 Growing Threat: Why It Matters Now
-
Security firm Koi Security uncovered over 18 malicious extensions downloaded by more than 2.3 million users across Chrome and Edge.
-
These extensions masquerade as helpful tools—emoji keyboards, volume boosters, color pickers, weather updates, and VPNs.
-
Once installed, they track every URL a user visits, exfiltrate data, and can redirect browsing to malicious websites.
-
High-profile cases include the “Volume Max – Ultimate Sound Booster” extension flagged for spyware risk.
🕵️ How These Extensions Operate
-
Install: They appear legitimate with positive reviews and Chrome verification.
-
Background Monitoring: Run a listener on every page load to capture URLs and browsing patterns.
-
Data Exfiltration: Transfer data to remote servers along with unique tracking IDs.
-
Malicious Control: Servers can command redirects to phishing sites, malware downloads, or targeted ads.
These extensions may be clean initially but transform through malicious updates—a tactic known as supply-chain hijacking.
