On the heels of a massive cyberattack that affected its 145 million users, eBay is reportedly facing a formal investigation with the government over its security practices. As first reported by CNET, eBay will have to answer questions from the government about what type of security the company had in place before hackers accessed the personal data of its users. Earlier this week, eBay urged users to update their passwords immediately. The breach, which was confirmed by investigators this week, happened in late February and early March; eBay discovered it in early May.
