What is a Zero-Day (0-Day)?

In the world of cybersecurity, zero-day vulnerabilities, zero-day attacks, and zero-day exploits keep many CISOs up at night. These terms, often shrouded in mystery and intrigue, denote a significant risk to digital systems and the sensitive data they hold. Understanding the intricacies of zero-day vulnerabilities and the exploits that leverage them is crucial for individuals, organizations, and governments seeking to fortify their defenses against cyber threats.

A Look at CISA's Top Routinely Exploited Vulnerabilities

Knowing what vulnerabilities interest malicious actors is a critical step in assessing the risk of vulnerabilities found in your environment. On August 3rd, CISA released their Top Routinely Exploited Vulnerabilities report for the year 2022 and inside comes little surprise as to most of the culprits. Bugs tied to ransomware incidents continue to dominate the eyes of the agencies behind these joint advisories in hopes that the number of complete owns will diminish.

The State of Citrix Zero-Day Vulnerabilities 2023

Critical zero-day Citrix CVE-2023-3519 is still being exploited two months after Citrix released a patch. IONIX research found that 19% of the CVE-2023-3519 vulnerabilities are still unmitigated in comparison to only 3% among IONIX customers. In addition, IONIX customers were able to resolve this critical risk three times faster.

Cybersecurity Venture's 2023 Software Supply Chain Attack Report

Most enterprises' critical infrastructure and operational pipelines rely on an intricate web of software, online services, and cloud applications. This level of complexity makes supply chain risk management one of (if not the) biggest challenges for CISOs today. Today, malicious actors choose to exploit software supply chain vulnerabilities rather than just target end users. These SSC attacks have caused some of the most notable cybersecurity incidents and data breaches in recent years.
