Part 3: Bonus: What to Do if Your Email Account Gets Hacked

Now that we have stated the way to detect email and password data breach, here are the steps you should take immediately if your email account gets hacked.

Step 1: Scan For Spyware

Why is your email information being leaked?

The reason your email account has been hacked could be sitting on your phone. Hackers deploy spyware and keylogger on phones through malicious files and apps. These spyware and keylogger record your activities and keystrokes and send them to the hacker's server. Hackers analyze them and find out your email address and password as well as credentials of other online accounts.

That is why you need to run a scan and detect spyware presence. You can use your antivirus app for scanning if you already have one on your phone.

However, it will recommend you ClevGuard Anti-Spyware for thorough scanning and detection as well as instant deletion. Besides, you are getting email data breach notifications through the app which is the most important requirement these days.

Step 2: Change Email Address's Password

After you get rid of spyware and keylogger, you should change the password of your email address. If it is exposed but not hacked, then you can change the password easily. However, if it is hacked, then it is most likely that you cannot log in and change your password.

You need to opt for forgot password option and give proof that you are the real owner of the email address. The proof includes answering security questions, verification code sent to your phone number, or whatever options provided by your email provider.

Otherwise, you can contact the email provider directly and ask them to recover your account on your behalf after necessary verification.

Step 3: Turn on Two-Factor Authentication

If not already, you should turn on two-factor authentication. Once it is turned on, even if the hacker gets your email address and password, he cannot hack it.

This is because when you have two-factor authentication turned on, you have to enter a verification code sent to your phone number.

It is not possible for hackers to get that code without physical access to your phone, especially in the absence of any spyware.

Step 4: Change Security Questions

Every email provider asks the users to set certain security questions and answers that could come in handy while recovering their email addresses in case of an emergency.

If your email address has been hacked and you have recovered it, it is best if you change the security questions and answers.

This is because the hackers may have noted the questions and answers, and they may use them to reclaim your email address.

Step 5: Change Passwords of Other Online Accounts

There are various online accounts we link with your email address. It is quite natural for your email address to have emails containing credentials of your other online accounts.

Not just that, you might have used the same username and password for some online accounts as your email account. That is why those accounts are also at risk of getting hacked. Moreover, there could be some online accounts which you log in via email account.

All those accounts are at risk of getting exposed and hacked. That is why you need to change their password as soon as possible and turn on two-factor authentication wherever possible.

NOTE:

Most importantly, keep the passwords unique for each account and make them as strong as possible.

Step 6: Report the Hack

It is better that you report the hack to your email provider. You can fetch details such as when the hack happened, the location of the last login, and if only your email address is hacked or several email addresses are hacked.

If it is only yours, then there could be spyware on your phone or malware on your computer. If several email addresses have been hacked, then there is a case of a huge data breach.

Tip:

Moreover, reporting a hacking will help you recover your account if any future scenario of your email address being hacked occurs.

Conclusion

Email data breach is quite common even in major online companies of the world. If you are wondering, ‘Is a phishing email a data breach?’, nearly 40% of data breach attacks are performed by phishing and spyware attacks.
