Detecting Gmail Account Hack

Hello Friends,
Today I will share about the technique which you can use to catch the hacker.
If you are suspicious about some one accessing your Gmail account then you can follow these steps to verify it:

Check your Logs

Now, you can see lists of  last 10 IP addresses from where you or hacker had logged into your Gmail account(Previously only last 5 IP addresses were shown). IP address: An Internet Protocol address(IP address)  is a number assigned to devices(PC) in computer networks like telephone number is assigned to every telephone. 1st Column is Access type, if your are accessing your Gmail account from browser then you should see Browser in this column but if your Recent activity table is showing some POP access(Outlook, Thunderbird etc.), it may be a sign that your account has been compromised. 2nd Column is Location, this column shows your IP addresses from where you have accessed your account.  You can use this IP Locator website which will assist you in locating the geographical location of an IP Address. If one location is Pune and the other shows Chennai then someone else has accessed your account but if both shows same location then you need to know more information about this IP address.
1. Open up your Gmail account and navigate to the bottom of the page.

2. Click on details.
Open this whois website and enter the IP address. You will see lots of information like ISP name, address, contact number, email address etc which will help you to decide whether your account has been compromised or not.

Concurrent Sessions
If your mail is currently being accessed from another location, you will see  list of other session(s) in the Concurrent session information table. You can sign out all sessions other than your current session by clicking Sign out all other sessions and change your password if you think your account has been compromised.
