Defining Zero Day Attack

A Zero Day Attack is a type of cyberattack that takes advantage of software vulnerabilities that are unknown publicly and thus, have not been patched or addressed. These attacks can occur in any type of system, including but not limited to computer networks, software applications, and hardware components. By exploiting these unknown vulnerabilities, attackers can gain access to sensitive data, disrupt services, and cause damage to the system. As the system owner and blue team has no knowledge of the zero day vulnerability, they are unable to prevent the attack and are unable to take any corrective action until a patch is released.
