Does an Email Hacking Software really Exist?

    With my experience of over 10 years in the field of ethical hacking and information security, all I can tell you is that there exists no such ready-made software program (as shown and advertised on many websites) that can break into the service provider’s database and hack email passwords. This is just a myth! This may seem a bit disappointing for many, but this is the fact. However, it is still possible to easily hack email passwords using some of the alternative programs and ways as discussed below:
    Working Ways to Hack an Email Password:
    Even though it is impossible to hack the database and instantly crack the email password, it is still possible to trick the users so that they give away the password by themselves. This can be done using a handful of methods like keylogging, social engineering or phishing. However, the easiest and most effective way is by using keyloggers.
    A keylogger is a small program that records each and every keystroke a user types on the keyboard of a specific computer. So when you install a keylogger on the computer from where the target person is likely to access his/her email, it is possible to capture the password. Though keyloggers are not designed to hack email passwords, they can still be used to accomplish the job. Here is a list of some of the interesting facts about keyloggers:
    EASY TO USE: A keylogger does not require any special skills. Anyone with basic computer knowledge should be able to use it.
    REMAINS UNDETECTED: A keylogger will remain undetected after installation and operates in a total stealth mode. So, you need not worry about being caught or traced back.
    REMOTE INSTALLATION: In addition to installation on a location computer, keyloggers also support remote installation. That means you can also install it even on those computers for which you do not have physical access.
