Did you just log into your Yahoo account and found a security letter from the company that your account was hacked? Yahoo recently said that a billion users’ personal data was compromised and stolen from as early as 2013 and you may be one of them. This largest data hack is almost twice as big as the one disclosed by the company a few months ago. Yahoo, once a pioneer of internet technology in an investigation found information about the data hack. In a statement, Yahoo said, “Yahoo believes an unauthorised third party, in August 2013, stole data associated with more than one billion user accounts.” In the statement the company said, “Yahoo has taken steps to secure user accounts and is working closely with law enforcement.” A blog post by Yahoo’s chief security officer Bob Lord says that some fo the attacks were done by hackers who got hold of user accounts without using a password and instead relied on ‘forged cookies’ or data files. These are used to verify a user or the device from which they log in.

According to Yahoo, this incident of the data breach is different from the one it had informed on September 22, 2016. That time it affected half as many users. Yahoo recently made a deal with Verizon to sell its core parts, and according to reports this partnership might get affected. Yahoo with the help of outside cyber forensic experts found that the data of users was compromised but it has still not been able to trace the intrusion source. Verizon said in a statement said, “As we’ve said all along, we will evaluate the situation as Yahoo continues its investigation.” So as long as the investigations are going on, here’s what you can do to if your account was hacked:

You should check your bank accounts, as the main motive of hackers is to attack online banking after accessing your Yahoo accounts. Yahoo, in a security notice, said, “Although the affected account information did not include passwords in clear text, payment card data, or bank account information, we encourage you to remain vigilant by reviewing your account statements and monitoring your credit reports.” You should change your password and also the security questions and answers especially if you have not done so since 2013 when the breach has been traced back to. Also, change the password and questions & answers for other accounts which you might have linked to your Yahoo account. You also need to review carefully in order to trace suspicious activity. You need to be careful of unsolicited emails which might have asked you for your personal information or make you click on random websites.
