Exploiting ancient vulnerabilities: How did the 3CX supply chain attack occur and what can we learn from it?

On March 29th, North-Korean linked threat-actors targeted 3CX, a VoIP IPX developer, exploiting a 10-year-old vulnerability (CVE-2013-3900) that made executables appear to be legitimately signed by Microsoft when, in fact, they were being used to distribute malware. The 3CX attack is just the latest in a series of high-profile supply chain attacks over the past year. The SolarWinds attack compromised the Orion system, affecting thousands of organizations, and the Kaseya VSA attack that was used to deliver REvil ransomware also to thousands of organizations and is considered one of the largest security breaches of the 21st century.

The Implications of CVSS 4.0 for Cybersecurity

Infosec teams rely on metrics and frameworks to prioritize vulnerabilities and understand their potential impact as part of their vulnerability management programs. These metrics are crucial for organizations to assess the impact of any vulnerabilities identified during any type of vulnerability assessment. One such framework widely used by penetration testing organizations and security tools is the Common Vulnerability Scoring System (CVSS).
