generated: '2026-09-05' method: probed source: live DNS/TLS/HTTP probes of the 8percent.kr registrable domain and every first-party host named in the 8percent.kr production JavaScript bundle (/assets/index-DenshHdQ.js) notes: >- Every first-party host terminates TLS 1.3 with a valid certificate, but not one of them returns a Strict-Transport-Security header — including core-api.8percent.kr, the JSON API host the consumer app calls. The 8percent.kr zone is not DNSSEC-signed and publishes no CAA record, so certificate issuance is unconstrained. SPF and DMARC are both published, with DMARC at p=quarantine. hosts: - host: 8percent.kr https: true tls_version: TLSv1.3 cert_expires: Jan 26 23:59:59 2027 GMT hsts: false - host: core-api.8percent.kr https: true tls_version: TLSv1.3 cert_expires: Feb 7 23:59:59 2027 GMT hsts: false note: JSON API host for the consumer app; GET /health returns 200 application/json - host: api.8percent.kr https: true tls_version: TLSv1.3 cert_expires: Feb 7 23:59:59 2027 GMT hsts: false - host: loan.8percent.kr https: true tls_version: TLSv1.3 cert_expires: Mar 7 23:59:59 2027 GMT hsts: false - host: events.8percent.kr https: true tls_version: TLSv1.3 cert_expires: Dec 5 23:59:59 2026 GMT hsts: false - host: about.8percent.kr https: true tls_version: TLSv1.3 cert_expires: Nov 4 23:59:59 2026 GMT hsts: false - host: blog.8percent.kr https: true tls_version: TLSv1.3 cert_expires: Nov 16 23:59:59 2026 GMT hsts: false domains: - domain: 8percent.kr dnssec: false caa: [] spf: true dmarc: true dmarc_policy: quarantine
