More than two thousand sites using Extended Validation certificates stopped working this weekend and remain inaccessible today (Monday), including those run by banks, governments, and online shops. The EV certificates used by these sites were revoked on Saturday, and have yet to be replaced. Most visitors using modern web browsers are completely locked out: this certificate error cannot be bypassed in Chrome, Firefox, Safari, or Microsoft Edge.

Last week, DigiCert disclosed a reporting discrepancy in its audit for EV certificates. As part of its response, DigiCert committed to revoking the certificates, which it intends to complete over the coming weeks. Only a subset of DigiCert’s EV certificates are affected: in the July SSL Server Survey, Netcraft found 17,200 EV certificates in active use on port 443 that are due to be revoked.
The first batch of revocations happened this weekend. While most of the certificates revoked on Saturday 11th July have been correctly replaced and reinstalled, many have not.
On Monday morning, Netcraft found 3,800 sites still using EV certificates issued by the affected sub-CAs. Of these 3,800, more than 2,300 were still using a revoked EV certificate, completely disabling the sites for users in modern browsers, which handle EV revocation more robustly than other types of certificate. The remainder are yet to be revoked.
Many organisations appear to have been caught unawares, continuing to use revoked EV certificates, including The State Bank of India, Rackspace, Authorize.net, ANZ Bank, and Telegram.

Wirecard, the beleaguered German payment processor, briefly had its main site, www.wirecard.com, displaying a certificate warning early on Monday, but the certificate has since been replaced with a working non-EV certificate. There are still a number of Wirecard domains with revoked certificate warnings.
