How can I know that my Gmail is spoofed or sending spams to other people I sent email to them before? I don't have clear signs of that especially my contact list is empty but I'm afraid this may happen later as I clicked on a strange link in a mobile app.


If someone spoofs your Gmail account, there is no possible way for you to know that. That would be like being able to know if I introduce myself to others as Ali Zahy. The receivers would know if they inspected the headers of those emails, though.

You might be able to determine if your actual account was used to send emails by looking at your sent and deleted folders. But if the malicious emails were permanently deleted, there would be no way for you to know. But, again, the proof is on the receiver's side.

  • Thanks a lot. But how can a bad guy get the contact list easily? Mustn't he get permission from Google to get it? And what are the other ways that may make my address get spoofed. – Ali Zahy Jan 26 '19 at 22:20
  • In order to get your contact list, the attacker must gain access to your account. Spoofing email addresses is very simple. With the right tool, you just enter your email address as the sending address. It's really quite simple. I can send anyone an email that says it comes from alizahy@gmail.com, for instance. – schroeder Jan 26 '19 at 22:24
  • Do all the apps downloaded from the play store have access to the account? Or they must require that in their permissions before installation? – Ali Zahy Jan 26 '19 at 22:29
  • They must request permissions. – schroeder Jan 26 '19 at 22:29
  • Thank you for your prompt response. Also, I heard the term 'bounce back'; is that sent to me when the spam is sent? Cannot the attacker delete the mail from the sent folder before I see it? One last thing; do you see any precautions that can be taken to secure my account after I clicked this link knowing that I haven't recevied a complaint from anyone? Or should I change my email address? – Ali Zahy Jan 26 '19 at 22:36
