The state of public PKI in 2026 — three migrated failure modes

Cryptanalytic audit of 44.6 million X.509 certificates collected via Certificate Transparency and active TLS probing. Four detectors (batch GCD, Fermat factorisation, Hidden Number Problem / lattice reduction, CA mis-issuance) run at corpus scale. Cryptographic risk has not disappeared — it has migrated into the firmware/IoT long tail, into voluntary key concentration at certain operators, and into time-handling design defects in embedded certificate generation code.
