Issue with Malicious Certificate on iPhone




Subject: Issue with Malicious Certificate on iPhone




Dear Apple Support,




I am experiencing an issue with my iPhone (model 15) after transferring data from my previous iPhone 11. A window keeps popping up with the message:




“Cannot verify server identity.


The authenticity of the application ‘ro3.biz’ cannot be verified. To continue, please review the certificate details.”




I am concerned that this may be related to malicious software or an insecure certificate. The domain “ro3.biz” seems suspicious and may be causing this issue.




I would appreciate any assistance in resolving this problem, as it is affecting my device’s security.




Thank you in advance for your help.




Best regards,


[Anastasija]



iPhone 15 Plus, iOS 18

No, nothing malicious on your phone. You have a rogue calendar that you accidentally installed or were tricked into installing. Go to Settings/Apps/Calendar/Accounts, find the subscribed calendar and delete it.
