Acunetix 360 detected a revoked SSL certificate. Certificate revocation is a process of invalidating an issued SSL certificate. Sometimes a Certificate Authority may revoke an SSL certificate if, for example, a domain is suspected of phishing/malware/etc, if the certificate owner has violated the terms and conditions, or if a certificate was wrongfully issued.
It can impact both website and the users:
- Warning error messages displayed by browsers when visiting the site
- Personal information at risk from man-in-the-middle attacks
- Reduction in trust as the site becomes insecure
- Ability for an attacker to create identical phishing website
The process of reissuing revoked SSL certificates varies depending on the host or the certificate authority used. Please refer to the corresponding documentation.
