A zero-day attack, also known as a zero-day exploit, is a cyber attack that exploits a previously unknown vulnerability in computer software or hardware. The term “zero-day” refers to the fact that the attack occurs on the same day the vulnerability is discovered, leaving no time for the targeted entity to prepare or defend against it. These attacks are particularly dangerous due to their unexpected nature and the lack of available defenses.
Zero-day attacks function by exploiting security flaws that have not yet been identified or patched by the software or hardware vendor. Cybercriminals discover these vulnerabilities through research, reverse engineering, or by purchasing information on the black market. Once identified, they develop and deploy malicious code to exploit the vulnerability.
This can result in unauthorized access to sensitive data, system failures, or complete control of the targeted system. The absence of patches or updates to address the unknown vulnerability makes defending against such attacks extremely challenging. These attacks can target various types of software and hardware, including operating systems, web browsers, and mobile applications.
They can be delivered through multiple vectors, such as phishing emails, malicious websites, or infected files. Successful zero-day attacks can have severe consequences for victims, including financial losses, reputational damage, and legal ramifications. Understanding the mechanics and potential impact of zero-day attacks is essential for organizations and individuals to protect themselves against this evolving threat.
