Zero-day vulnerabilities are critical security flaws that exist in software or systems before the developers are aware of them. These exploits pose significant risks to digital infrastructure and require advanced training to mitigate.

What Are Zero-Day Exploits?

  • Definition: A zero-day exploit is an attack that leverages an unknown vulnerability to compromise systems.
  • Impact: Attackers can exploit these gaps to steal data, execute malicious code, or disrupt services.
  • Defense: Proactive measures like threat intelligence and regular patching are essential to protect against zero-day attacks.
