Most people believe malware only arrives through file downloads. In reality, a device can be infected even when nothing is intentionally downloaded.
Common ways it happens
• Clicking a malicious link that exploits a browser or app vulnerability
• Visiting compromised websites that execute code in the background
• Malicious ads served on legitimate websites
• Browser or app extensions with excessive permissions
• Documents that trigger malicious activity when opened
Why it works
• Users do not expect risk without a download
• Many actions happen automatically in the background
• Unpatched vulnerabilities allow silent execution
How to reduce the risk
• Keep browsers, apps, and operating systems up to date
• Be cautious with links, even on trusted platforms
• Limit extensions and app permissions
• Use security tools that detect threats in real time
