Published Date: December 18, Yes No. Character limit: Maximum character limit is Web sites which want to operate on the web need to request a certificate from a third party certificate authority CA , such as Comodo. It appears that what happened in this incident is that a hacker managed to break into a Comodo affiliate, or registration authority RA in Italy, and used stolen user name and password credentials to request nine SSL certificates in seven different domains.
The compromise was detected within hours and the certs revoked immediately, but they could have been used by the hacker to host fake phishing sites claiming to be original versions of sites like Yahoo or Google email log-in pages.
The nine certificates in question were for the following domains: login. It also reassured that no hardware or any other part of the authentication and online trust chain was compromised.
In addition, Microsoft, Google and Mozilla all issued updates so users of their browsers would be notified if they tried to visit a site which was authenticated by one of the dodgy certs.
Panic over then, but the questions remain about the underlying system for authenticating web sites, as well as the security employed by Comodo and its partners which allowed the hacker to break in. Comodo was quick to brand the attack highly sophisticated and carried out by the Iranian authorities. It also discounted financially-motivated cyber criminals as the domains targeted were not those of banks or other potentially lucrative sites. For example, all Sectigo code signing certificates are signed by a code signing intermediate.
All certificates won't show the Comodo brand name anymore. Already issued certificates remain trusted worldwide until their expiry date, there's no action needed. The new root structure will be used from January 14, for all new certificate requests and renewals. The old structure will be used for certificate reissues. Like always, we send you the correct root - and intermediate certificates on certificate delivery. You can also download them. In this case an error will be shown to website visitors.
How can you fix this? The easiest and best way is updating your systems. Next to this, there is a temporary solution that works until early using a cross signed intermediate certificate. The image below left shows the Comodo CA logo that was used last year, after the acquisition by Fransisco partners.
Before the acquisition, the red logo on the right was used. By now, both logo's are out of date. The first image below shows the logo that can be used up to November 1st,
