AI Summary

This case involves Sectigo's disclosure of a compliance issue regarding the use of invalid stateOrProvinceName values in certificates. The issue was initially reported on May 8, 2021, when a certificate with 'stateOrProvinceName: Moldova' was identified. Sectigo acknowledged the problem and subsequently revoked six certificates with invalid state names, including those with 'Malta' and 'Moldova'. The CA has since implemented a lookup table based on ISO 3166-2 to prevent future occurrences of similar issues. The case has been resolved with all identified certificates revoked.
