This week Liang presented our work on PKI vulnerabilities at IMC'14. We measured how quickly the SSL certificates that may have been compromised by Heartbleed were revoked and reissued after the vulnerability was disclosed. A common assumption is that these operations occur at the same time, as reissuing compromised certificates without revoking them would not prevent attackers from conducting phishing and man-in-the-middle attacks. However, we found a significant gap between the rate of reissues and the rate of revocations. 73% of vulnerable certificates had yet to be reissued and 87% had yet to be revoked three weeks after Heartbleed was disclosed. The paper includes a longer discussion about the causes and implications of this problem.
