To a skilled adversary, zero-day exploits are the perfect avenue that can be used to launch cyberattacks against their targets. As a result, zero-day attacks have increased significantly in the past year. Zero-day exploits cannot always be prevented because the software vulnerabilities are identified by the vendor only after the fact. However, through Managed Detection and Response (MDR) the follow-on intrusions can be detected and responded to in a way that minimizes the impact of these cybersecurity incidents.
In this zero-day attack threat intelligence report, eSentire's Threat Response Unit (TRU) performed a thorough analysis of zero-day vulnerabilities and how they’ve grown in 2021.
Key takeaways include:
- Identifying the opportunity windows for zero-day attacks
- Detecting and responding to zero-day exploits
- Case studies on the ProxyLogon, ProxyShell, and Kaseya VSA zero-days
- Recommendations for your in-house IT and cybersecurity team to defend against zero-day exploits
