However, it didn’t include data like credit card details and bank account information, as it wasn’t stored on the hacked server.In the case of the 2014 attack, Yahoo has tied links to some state-sponsored attacker, who gained access to Yahoo’s proprietary source code and created forged cookies to compromise user accounts.Verizon is already in the process of acquiring Yahoo for $4.8 billion, and the company has negotiation terms in mind due to multiple hacking incidents like this. Yahoo has also been accused of creating email scanning software to scan people’s email on behalf of the US government. It was known that Yahoo’s CEO Merissa Mayer gave a green signal without seeking any advice from the security department.
