Zero Day Vulnerability

 


1. What Is a Zero-Day Vulnerability?

A zero-day vulnerability is an undiscovered security flaw within software, hardware, or network infrastructure that remains unknown to the vendor. 

The term “zero-day” signifies that developers have had zero days to create a fix before cybercriminals exploit the weakness.

Why It Matters

Cybercriminals actively seek out these vulnerabilities to conduct zero-day exploits, often targeting businesses, government systems, and individual users.

2. How Zero-Day Attacks Work

Discovery of the Vulnerability

  • Hackers, security researchers, or ethical hackers identify unknown weaknesses in software or systems.

Creation of the Exploit

  • Cybercriminals develop malware or scripts specifically designed to take advantage of the flaw.

Deployment of the Attack

  • Threat actors launch a zero-day attack to gain unauthorized access, steal data, or disrupt critical operations.

Detection and Patch Development

  • Security teams rush to identify the breach and create a security patch before further damage occurs.

Implementation of Fixes

  • Businesses and users apply the patch to mitigate the risk of further exploitation.

The term “clickjacking” is a combination of “click” and “hijacking,” accurately describing how the attacker takes control of a user’s actions without their knowledge. By overlaying an invisible or disguised button over a legitimate one, users may think they are performing a safe action but are triggering something harmful, like sharing sensitive data or performing unauthorized tasks. This kind of ...
