2. About Zero-Day Attack: Zero-Day Attack refers to the immediate exploitation of a ZDV, with no time-lapse between the vulnerability’s discovery and the commencement of the attack. A Zero-Day Attack transpires when threat actors swiftly develop and deploy malware specifically designed to target the ZDV.
3. About Zero-Day Exploit: Zero-Day Exploit refers to the method employed by hackers to capitalize on a ZDV, often through the deployment of malware, facilitating the execution of the attack.
Risks Associated with Zero-Day Vulnerabilities
