Detect and Respond to Zero-Day Exploits

A zero-day attack refers to a cyberattack that takes advantage of an exploit in a software application that is not known to the software vendor that exposes a vulnerability in software or hardware that cybercriminals use to gain access into your environment. Zero-day vulnerabilities are challenging to defend against since the exploit is already in the wild when it's discovered and they can last for weeks or months before they are detected and investigated, at which point the software vendor can develop a patch.

A zero-day attack occurs when a cybercriminal finds a zero-day vulnerability, or zero-day exploit, and uses it to launch cyberattacks to gain access to your environment, steal data, and/or sell data to other criminals on the dark web, etc.

A zero-day attack can cause extensive damage to your organization, including data theft, financial loss, reputation damage, and disruption to business operations. Plus, if your organization doesn’t have 24/7 threat detection and response capabilities to detect the attackers’ presence, attackers can continue to use the zero-day vulnerability or exploit until the software vendor makes a patch for it available to their customers.

Zero-day attacks target businesses of all types and sizes. They are typically aimed at entities with valuable data or resources.

A zero-day attack can last a matter of hours, days, weeks, or even years in some cases. Because of their covert nature, zero-day attacks can persist undetected for a long time. They continue to be exploited by threat actors until the vulnerability is detected and investigated, which can finally alert the software vendor to develop a patch.

Your organization’s ability to withstand a zero-day attack is completely dependent upon your capacity to detect and respond to an incident post-exploitation.
