How this is built

Junglewise Threat Intelligence collects vulnerabilities from NVD, GitHub Security Advisories, OSV, the CISA Known Exploited Vulnerabilities catalog, FIRST EPSS and vendor advisories, and matches each one to the technologies and vendors it affects. Dates are the date a vulnerability was published, in UTC.

A vulnerability is exploited in the wild when the CISA Known Exploited Vulnerabilities catalogue lists it or a vendor advisory says so. The date it was first recorded as exploited is CISA's date added where it came from the catalogue, else the day Junglewise learned of it.

The pages are rebuilt from the database every hour. Frozen weekly and monthly reports never change once published, so they can be cited.
