How much is your personal information worth? It is believed that most people think that it is "unvaluable." Whether it is a user name, password, mobile phone number, or ID card number, address, email address, etc., there is no specific quantitative standard for such information.
This time, the leakage of user information at station A indicates that domestic user information is "quite cheap", and 800 messages can be bought for 1 yuan.
In the early hours of June 13th, Station A issued a public statement saying that nearly tens of millions of user data had been leaked due to the hacking of the website. It is strongly recommended that users with hidden security risks change their passwords in time.
According to the statement, the leaked user data includes user ID, user nickname, and encrypted stored password. At the same time, the announcement also reminds that all user passwords of AcFun are encrypted and there is no clear text password (clear text password refers to a password that is not encrypted and can be directly understood, such as 123456). But if your password is too simple, it is also recommended to change the password.
Special reminder at station A: It is recommended that users change their passwords as soon as possible. If users use the same password on other websites, please change it in time. AcFun will take technical measures, this part of the user's account will be required to change the password when logging in again.
The data has been sold on the dark network for 1 yuan to buy 800 user dataAccording to reliable sources, in March of this year, someone on the dark website publicly peddled the user data of station A. According to network screenshots, the number of user information involved in station A was about 8 million at the time, the price was only 12,000 yuan, and an average of 800 yuan can buy 800, requiring Bitcoin to be used for payment.
And Freebuf reported that "before AcFun released this data breach announcement, someone on the dark web was already selling its Shell and intranet permissions, the main selling points are the large amount of data and high daily traffic." The screenshot shows that the daily traffic exceeds one million, the database contains 9 million pieces of user data, and the price is 400,000 yuan.
"Robbery" at Station AAs the earliest barrage video website in China, Station A is the birthplace of Chinese secondary culture. It uses video as a carrier to develop a complete ecology based on secondary creation of native content. It has both high-quality interactive barrage and a large number of loyal fans, resulting in a large number of online popular culture.
However, the development of the A station has become increasingly difficult in recent years. Not only has the limelight been snatched away by the B station, but also the problems such as the inaccessibility of the website and the arrears of employees' wages have been repeatedly exposed.
"Securities Daily" reported that "station A was in a difficult situation, and the risk of stopping at any time, so the value of the data is not high." However, on June 5, Kuaishou wholly acquired Station A, allowing it to temporarily overcome the difficulties. The hacker saw the opportunity and wanted to cash out the data as soon as possible.
For this incident, Station A announced that it will take the following measures:
1. It is strongly recommended that users with hidden security risks change their passwords as soon as possible. Hidden accounts that have not actively changed their passwords in a timely manner will be required to change their passwords when logging in again for access.
2. After the incident, the internal and external technical experts were set up as soon as possible to set up a special security team to troubleshoot problems and upgrade the system security level.
3. Comprehensively strengthen the AcFun service to upgrade the technical architecture and security system.
4. Collect relevant evidence and report to the police.
A report from freebuf stated that "the personnel involved have published data and passwords on GitHub." The screenshot shows that the person involved said, "This event of selling data and shells is the result of multiple letters sent to the official email of AcFun without reply. As a multi-year fan of secondary yuan and a leak of information I do n’t want people who are deeply disgusted to destroy the once beautiful A station like this, and user information is misused. We want to reach a consensus with the official, we hope to destroy this batch of data, we hope to help A station through the near future The storm has made Station B always have a competitor (hardcore fan of Station A). "
For this incident, the station A's own security awareness is insufficient, and the site's security work is not in place. In the Internet era, cyber attacks and data leakage are becoming more and more serious. I hope that everyone and every company can continue to pay attention to network security issues.
