No, the leak was not the result of a security breach of Google systems. The dump is said to have been obtained from other websites.
So, if you have used the same password used anywhere else, your gmail account could be compromised.
“We found that less than 2% of the username and password combinations might have worked, and our automated anti-hijacking systems would have blocked many of those login attempts. We’ve protected the affected accounts and have required those users to reset their passwords.” Google wrote.
What You should do?
- There are few websites available online to check whether your gmail ID have been compromised or not. My suggestion is don’t use them. I suggest everyone to change the password.(I believe most of the people keep the same password for years, so it’s better to change now).
- If you have not enabled 2-step-factor feature, it is good to enable it.
- Never use the gmail password in any other websites.
