Am I getting HACKED? Someone might be trying to do a MITM attack Attacker will capture the traffic between your computer & server Can¡¯t decrypt HTTPS traffic if it uses valid certificate Will impersonate the certificate Encrypt your data with HIS certificate, decrypt the same at his end, encrypt again with original server certificate & send to server YOU ARE HACKED!
OK, I get valid certificates But you are still not secure Most of the websites uses only password authentication over HTTPS Your mails/traffic still goes in plain text. WHY ??? Its an expensive mechanism (time & effort) A trade-off between speed & security
So what to do? Try using mail clients  (thunderbird / outlook / whatever) rather than web browser Atleast all the traffic is encrypted, it adds a little latency though, but on the other hand gives me ease to manage my mails Change the URL & force it to go over HTTPS That¡¯s for emails, what for other apps? Use client applications as much as possible
Nothing is 100% secure But a smart netizen can atleast be 80-90% safe  ? ? Q & 42
