How do I tell the difference between a theoretical vulnerability and a weaponised exploit?

A theoretical vulnerability is a disclosed security flaw that may have limited practical exploitation potential, while a weaponised exploit has been actively operationalised by attackers using exploit kits, malware, ransomware campaigns, or automated attack tooling. Vulnerabilities with public proof-of-concept exploits, KEV inclusion, or observed attack activity typically require higher remediation priority.

What role does threat intelligence play in predictive vulnerability scoring?

Threat intelligence improves predictive vulnerability scoring by analysing exploit activity, attacker behaviour, ransomware campaigns, proof-of-concept releases, asset exposure, and real-world targeting trends. This helps organisations prioritise vulnerabilities based on actual exploitation likelihood rather than relying solely on static severity ratings such as CVSS.

What is exploit prediction scoring (EPSS) and how does it compare to CVSS?

EPSS (Exploit Prediction Scoring System) estimates the likelihood that a vulnerability will be exploited in the wild, while CVSS measures technical severity and potential impact. Unlike CVSS, EPSS focuses on real-world exploitation probability using threat intelligence and historical exploit data, making it highly valuable for vulnerability prioritisation and operational risk management.
