Yahoo has confirmed that its over 500 million user accounts have been compromised. The company is calling it a state-sponsored attack, and according to Yahoo s Chief Information Security Officer, the information was stolen from the company s servers back in late 2014. Due to the breach, sensitive user information like email address, telephone numbers, date of birth and decrypted password may have been leaked to the hackers. Although Yahoo has claimed that the stolen information did not include unprotected passwords, payment card data, or bank account information, users are strictly recommended to take a few preventive measures.

However, first things first, and you need to know if your account is actually among the 500 million affected. First of all, you would receive an email from Yahoo on your Yahoo mail to inform you that your data has been breached. Users on Twitter have been sharing the email they received from the company, alerting them of the hack. If you haven t received such an email, your account may not have been compromised. But regardless, be a little more alert than usual about any suspicious activity or messages on your account, or any link that is strange and prompts you to click on it.

Also, Yahoo on its help page lists some of the signs that indicate that your account may have been compromised. So keep an eye if your account information has changed without your knowledge. Also, check your recent activity history, by going to Yahoo account info , there you will see a detailed log of the most recent logins into your account. If any of the logins were not made by you, your account may have been hacked into. Other than that, signs like not receiving your expected or usual emails, or your Yahoo Mail account sending out spam, may also indicated a account compromise.

There are also websites like haveibeenpwnd that tell you if your account has been pawned . So if you go to the website, it will ask for your email address, so you put in your Yahoo email ID in there, and it will tell you if your account was compromised. I put in my Yahoo email address, and fortunately, mine came out clean. Interestingly, the site tells you not only if your account has been or has not been hacked, but it also gives you details on when the breach occurred and exactly what information was impacted.
Also, very importantly, whether or not your account has been hacked, even if you did not receive a declaration from Yahoo about the attack, you must change your passwords immediately and enable two-factor authentication. In a case where your password has been changed by the hackers, you can go through a Forgot Password procedure.
