Apple said over the weekend it would soon distrust certificates issued by WoSign s Free SSL Certificate G2 intermediate CA on MacOS. Mozilla accused the CA of backdating SHA-1 certificates to effectively bypass restrictions banning them from being trusted. Apple said it would give current WoSign certificate holders a chance to transition to trusted roots, as long as their certificates were published to log servers by Sept. 9. Mozilla’s CA team said last week that in wake of the discovery, and several other wrongdoings, it was considering blocking the the WoSign and its subsidiary StartCom.
