Adding to the snow, Yahoo user data leakage has expanded to 1 billion

Beijing time on December 15th news, according to foreign media reports, although it has been sold to Verizon, but the old Internet giant Yahoo is still troublesome, after the last exposure of 500 million user data leaks, they have appeared more serious security problems. Today, the company said it has discovered a new security vulnerability that dates back to August 2013, which caused the theft of at least 1 billion users' names, emails and passwords.

Yahoo chief information security officer Rhodes said the vulnerability was reported by a third-party security company. The most shocking thing is that this data breach is not related to the 500 million user data breach in September this year, which means In just three months, the total number of Yahoo user data leaks has reached 1.5 billion.

Yahoo chief information security officer Rhodes said the vulnerability was reported by a third-party security company. The most shocking thing is that this data breach is not related to the 500 million user data breach in September this year, which means In just three months, the total number of Yahoo user data leaks has reached 1.5 billion.

It is reported that this password leakage is because Yahoo used the MD5 algorithm, and this algorithm was already a pediatrics for hackers in 2013. Therefore, these accounts are simply undefended for hackers.

At the same time, Yahoo has also discovered new hacking actions that are invading the company's cookie system (used to identify logged-in users). Rhodes' report shows that a group of hackers have successfully acquired Yahoo's proprietary source code and used them as a blame. The result is the collapse of Yahoo's entire security system.

The scale of this information disclosure incident is too large. Yahoo will once again become the focus of public opinion. This will be a fatal blow to Yahoo, which is in the critical period of acquisition. After all, after the leak in September, Verizon showed it. Hesitant emotions, this time I will be hit again, I am afraid they will feel that the price of 4.8 billion US dollars is not worth it.

Verizon said in the statement: "We will evaluate the incident and we will continue to pay attention to the impact of the information disclosure incident before the investigation is completed."
