When the infected software is launched or a system is booted, the preexisting malware can infect the application, operating system (OS), firmware, and/or system memory, compromising the data and functionality of an individual device or an entire network. Zero-day attacks can pose a serious threat to an organization’s cybersecurity and data integrity. Hackers then take advantage of the vulnerability in a zero-day exploit-developing hard-to-detect malware or viruses-and further leverage the exploit to launch a zero-day attack. Hackers may discover the flawed code and resulting vulnerability, even when the issue is undetected by developers, IT teams, and business users. In many cases, the zero-day vulnerability was present when the code was developed. If developers and IT departments have no advance warning of the bug, they are said to have “zero days” to repair the damage and block the threat. When a flaw in computer code has the potential to be exploited by hackers, that creates a zero-day vulnerability. Defining Zero-Day Exploits, Vulnerabilities, and Attacks
