This is a question from many teachers here. Do you think that this page is hacked?
https://cyearn.pi.ac.cy/webmail/login/
It is a webmail page, of a department of the Ministry of Education.
Is there anything we can advise?
No, it is not hacked. From the "Technical Details" when getting the "Untrusted" notice:
Quotecyearn.pi.ac.cy uses an invalid security certificate. The certificate expired on Tuesday, May 21, 2019 8:00 AM. The current time is Tuesday, May 21, 2019 2:09 PM.
What does that mean? (invalid security certificate and certificate's expiration date)
A website security certificate is part of the HTTPS protocol. It secures and encrypts data going between the server and the browser. It is issued by a trusted certification authority (CA) who verifies the identity of the owner of a website. There is a fee for Security Certificates. Some are renewed automatically, others are not. Bottom line, the site needs to renew its Security Certificate.
Thanks. End of the alarm. :)
