Yahoo reveals the worst data breach ever, with accounts involving up to one billion

　　On the morning of December 14, Yahoo announced that the company discovered another large-scale hacking incident, and this incident can be said to be a well-known online account stolen in history. Yahoo believes that the data stolen was dominated by government-controlled hackers, and the scale of this time doubled compared to the data stolen in 2014.

　　"Yahoo is in a bad situation. It's obvious that they don't pay attention to security issues. It's hard for me to trust Yahoo in the future."

　　It is understood that the previous account stolen incident affected at least 500 million accounts. Verizon even stated in October that it may cancel the agreement to acquire Yahoo's core assets of US$4.83 billion.

　　Verizon said the company will assess the impact of the matter before finalizing the decision.

　　A Yahoo spokesman told Reuters that the company had already communicated with Verizon during the investigation and they believed the matter would not affect the acquisition plan.

　　Yahoo has asked all users to reset their passwords.

　　Yahoo also said on Wednesday that the company believes that the hackers who launched the attack have been exposed to Yahoo's proprietary code and have learned how to access user accounts without entering a password by forging cookies.

　　The company said they discovered the matter while providing data to law enforcement agencies. A Yahoo spokesman said security companies Fire Eye and Aon Plc both sent experts to assist the company in launching an investigation.

　　Just hours before this matter was announced, executives from Google, Facebook and other major American tech companies had just attended a meeting chaired by President-elect Donald Trump in New York. According to people familiar with the matter, Yahoo was not invited to attend the meeting, which is enough to show that it has long been no longer in glory.

　　Yahoo's words were very cautious when describing the matter. They said the attack "may" be different from the incident announced in September this year. The stolen information "may contain" names, email addresses, phone numbers, dates of birth, hash passwords, and even encrypted or unencrypted security questions and answers.

　　The company has not identified the intrusion that led to the data breach, but they noted that payment cards and bank accounts were not stored on the affected servers.

　　A Yahoo spokesman said that the company's CEO Marissa Mayer is involved in the handling of the latest incident at the California headquarters.

　　Yahoo shares fell 2.4% to $39.91 in after-hours trading on Wednesday. Verizon's stock price was almost unaffected, closing at $51.63 throughout the day.

　　Yahoo can be said to be a pioneer in the Internet, but its development in recent years has not been very ideal. Up-and-coming stars such as Google and Facebook have surpassed Yahoo to a certain extent.
