Is your Gmail account compromised?
I’ve already discussed about how to secure your Gmail account from hacking. But it’s all about keeping your account safe by using a strong password, enabling two step verification and other method(s). But what if your Gmail account is hacked (or compromised)? The hacked would have already changed the password, security question & answer, mobile number associated with the account. So you can’t recover your Gmail using those primary account recovery methods.
But wait! Google allows you to recover your Google account using Knowledge Test process. All you need to do is answer few questions as thoroughly and accurately as possible; the strength of your answers will determine if they can return your account.
Your detailed answers will help them ensure that you’re the actual account holder and only you get access to your account.
What to do when your Gmail account is hacked?
Step 1: Go to Google Mail and click on “Can’t access your account?” link.

Step 2: Enter your Google Mail or Gmail ID.

Step 3: Complete the Captcha form.

Step 4: Click on “Verify your identity” link since the “Get a password reset link at my recovery email” and “Get a verification code on my phone” won’t work as hackers have already changed that.

Step 5: Verify your identity by answering multiple questions about your account.
Protect your Gmail account.
You can secure your Gmail account from hacking by following the article How To Secure Your Gmail Account From Hacking and then note down the following information somewhere (preferably in your personal diary) so that in case your Gmail account is hacked you can still recover your account using the following information.
1. Account Creation Date
To get your account creation date, go to “All Mail”, click on "Oldest" on the upper right, and get the date of the welcome mail from Google. If its deleted choose the date of the last mail in your “All Mail” to get an approximate date.
2. Verification Code (if you have it)
3. Email addresses of up to five frequently emailed contacts
To get the email address of your frequently emailed contacts go to “Contacts” and click “Most Contacted” choose five of your contacts from them.
4. Names of up to four labels
Did you receive an invitation to create your account? If so select “Yes” and enter the details if you can otherwise leave it blank.

That’s it! You’re done. Google will review your application and will contact you.

Hi,
Please use the account recovery form at http://support.google.com/accounts/bin/answer.py?hl=en&answer=183733.
You need to give as much information as you can about those accounts. That is the name of labels created, approx date of registration, information about other Google products linked to those accounts, your most frequently used contacts etc.
They review all applications manually and will guide you.
Thanks!
