Has your friend recently received an email from you that you are sure you haven’t sent? Or has your bank recently sent a mail asking you to revert back with your credentials and password. If the answer is yes, then it means your email has been compromised. You should immediately change your passwords to your online accounts. Here is a web service to check whether your email has spoofed or not.
To check whether your email address has compromised or not, visit HackNotifier (it is a free service), enter your email address in the field provided and click on “Have I Been Hacked” button.
The service will instantly show you whether your account has been compromised or not by checking your account against its database. It also shows websites and time on which your account was compromised and gives advice to change your password.
HackNotifier also offers a premium service, which includes instant notifications and alerts you via SMS or email when its databases are updated.
