257th eventful autumn

There is only Andrew in the glass room at the moment, but there are ten laptops and desktops.

Andrew's authority can only operate 4 of the computers, and the remaining 6 computers belong to the other two colleagues who are temporarily absent. Andrew's four computers, two computers that were not turned on, were not infected with the Bitcoin ransomware virus; one computer that was turned on but was locked and returned to the desktop after entering the password, but the red interface of the Bitcoin ransomware virus did not pop up.

Andrew breathed a sigh of relief: "It's okay."

If it is just a networked computer infected with a virus, it proves that the potential threat of Bitcoin ransomware is not strong, at least far inferior to the hacking incidents of the past few days.

In the branch office of the Cipher Center in Oahu, Hawaii, computers responsible for different businesses have different security levels. The computer operated by Andrew needs to be frequently connected to the Internet. From time to time, special permissions need to be activated to check the background information of Internet companies such as Google, Facebook, Twitter, etc. The hard disk rarely stores valuable information for a long time, and many retrieved materials are destroyed immediately after being read. The Oahu Crypto Center Branch in Hawaii reversed the hacking incident and found that the Trojan horse virus released by Wei Dongsheng had already infected multiple computers including physically isolated LANs. It was only when the Trojan horse virus quietly transferred the hacker toolkit to Andrew’s computer. Activate the download at the risk of being discovered.

In addition to a large number of hacking tools stolen by the Oahu Cryptographic Center branch in Hawaii, there are also many important intelligence materials targeting Russia, China, Germany, Iran, Pakistan, Algeria and other countries. The US National Security Agency suspects that the Avengers are the national hacker organization, or they have sold a large amount of intelligence information to Russia, China, Pakistan and other countries. About 4,500 intelligence personnel serving the US intelligence agencies have been leaked. Because more than a hundred key intelligence personnel lost contact in just half a month, and the potential loss was calculated in units of at least 100 million U.S. dollars.

And the Bitcoin ransomware in front of us, without infecting a computer with a password lock screen, proves that it has a great probability of instant intrusion and instant outbreak, and it will not download a large amount of files like a hacker intrusion. In this case, although the two failures in a short period of time give rise to a sense of humiliation for losing power and humiliating the country, the real loss should be within control.

The threat of Bitcoin ransomware is indeed weaker than the hacking incident, but Bitcoin ransomware is not as simple as Andrew thought. The worst part of Bitcoin ransomware is not to damage computer systems or steal your data, but to encrypt your files.

Forced to end the Bitcoin ransomware process, Andrew was depressed to find that all the documents in the computer had been encrypted.

Ordinary users often lack the habit of file backup, and find that the files are encrypted, which can only be dumbfounded and depressed. And in an organized group like the Oahu Crypto Center Branch in Hawaii, many documents need to be backed up across computers and servers. This is the vulnerability that the Avengers group Avengers_Group was able to steal the US National Security Agency hacker toolkit a few days ago. It is also a security protection mechanism that protects important documents from being deleted by intruders and encrypted by Bitcoin ransomware.

Under normal circumstances, the Hawaiian Oahu Cryptographic Center Branch is not afraid of Bitcoin ransomware.

However, it is not normal right now.

The Avengers released 108 hacking tools for free, which indirectly caused more than a hundred key intelligence personnel to lose contact. In addition to the anger of the US National Security Agency, it also urgently repaired firewall vulnerabilities, changed all permissions and passwords, and updated all security services. Such a large project cannot be completed in a few days. Therefore, many important documents cannot be backed up and then deleted immediately. It takes several hours or a day to centrally backup. The bad problem is here. All the data that could not be backed up in real time was encrypted by the Bitcoin ransomware virus.

The Oahu Cipher Center branch in Hawaii tried to violently decrypt it, but it quickly turned black.

Wei Dongsheng's version of Bitcoin ransomware is similar to the Bitcoin ransomware WannaCry in 30 years of memory, but its performance has been enhanced. Wei Dongsheng's version of Bitcoin ransomware WannaCry_Enhanced also adopts a three-level key structure, but it uses the Algo01 cryptographic algorithm secretly developed by computer intelligent life and supercomputer. The network key pair WK uses the Algo01 algorithm to protect the host key pair TK, the host key pair TK uses the Algo01 algorithm to protect the file key FK, and the file key FK uses the symmetric cryptographic algorithm AES to encrypt files.

Even if Wei Dongsheng uses the asymmetric cryptographic algorithm RSA to protect the host key pair TK and file key FK like WannaCry, the brute force cracking is too difficult to bear, let alone the Algo01 algorithm that Wei Dongsheng secretly developed? It can be said like this. That is, the National Security Agency has the ability to centralize all supercomputers in the United States. With current computer performance and brute force cracking speed, they will never be able to decrypt the encrypted files of the Hawaiian Oahu Cryptographic Center branch within their lifetime.

The employees of the Oahu Crypto Center Branch in Hawaii are discussing the Bitcoin ransomware from the impact and technical aspects. The department leaders who have the right to call suddenly receive a high-level call: Bitcoin ransomware is breaking out worldwide.

It turned out that at the same time that the Oahu Cryptographic Center branch in Hawaii was attacked, Bitcoin ransomware emerged from North America to South America, Japan to the United Kingdom, and countries around the world.

As of 0:00 on February 2, 2010, Yanjing time, 30,000 institutions around the world have been infected with the Bitcoin ransomware virus, and it is difficult to recover a large number of important data without backup.

During this period, in order to avoid targeted suspicion, Wei Dongsheng decisively introduced the Bitcoin ransomware virus into China and took the opportunity to strike at dissident forces. In other words, the Spring and Autumn Department has been developing in China for eight years, uniting countless allies through economic interest relations, and offended many forces because of their interest relations. For example, recently, they wanted to sacrifice the interests of the Spring and Autumn Department in exchange for the anti-zhiyu alliance that the United States promised not to raise tariffs. With the idea of ​​"killing the mistake but not letting it go", Wei Dongsheng commanded a brutal charge of the Bitcoin ransomware army, paralyzing one company after another of the anti-zhiyu alliance. Considering that people are accustomed to the thinking of "who gains, who is the mastermind", Wei Dongsheng expanded the scope of the attack with the anti-zhiyu alliance as the center point, and even deliberately injured the Chunqiu industry and weakened the suspicion of the Chunqiu family.

However, Wei Dongsheng has a spring and autumn security steward vest after all.

Wei Dong released the Bitcoin ransomware virus as a big villain before his life, and appeared in the Spring and Autumn Security Housekeeper as a salvation hero.

As early as Wei Dongsheng announced 108 hacking tools with the Avengers vest, Wei Dongsheng called the thief to catch the thief and ordered the Spring and Autumn Security Butler team to work around the clock. As soon as the Internet showed signs of Bitcoin ransomware virus, the Spring and Autumn Security Butler immediately forced a bullet box to warn users of the Bitcoin ransomware attack, reminding users to reduce the risk of infection with Bitcoin ransomware before the security patch came out. After that, Wei Dongsheng came to the Spring and Autumn Security Butler team in person to fight on the front line with security experts and employees to meet this global virus storm.

Wei Dongsheng personally supervised the Spring and Autumn Security Butler team to reduce the suspicion of the outside world.

In reality, Wei Dongsheng did not work hard, watching the Bitcoin blackmail virus sweep the world.

No, we cannot accuse Wei Dongsheng of failing to contribute. To say that Wei Dongsheng did not work hard means that Wei Dongsheng knew the weakness of the Bitcoin ransomware virus, but he kept silent and asked the Spring and Autumn Security Butler team to find it by themselves. And if you ignore the reality that Wei Dongsheng already knows the answer and that Wei Dongsheng holds a computer intelligent life, his "performance" in the Spring and Autumn Security Butler team is definitely not weaker than any security expert. In other words, Wei Dongsheng used a senior security expert as the standard to conceal the fact that he is the real man behind the scenes.

Programmers are very boring at work.

In order to prevent employees from suspecting that he was not working hard, Wei Dongsheng returned to the Liangbaihat hacker group during his break and communicated with civilian whitehat hackers as an itm.

Wei Dongsheng did not pay special attention to You Jinliang.

This is not that Wei Dongsheng is unfeeling, but that Wei Dongsheng feels it is unnecessary for the time being.

The icing on the cake has been common since ancient times, and it is hard to find charcoal in the snow. Wei Dongsheng’s personality is just the opposite. He seldom takes the initiative to do icing on the cake, and his energy often focuses on giving charcoal in the snow. If You Jinliang, Gao Yongqi, Undernet, etc. are currently poor, Wei Dongsheng will definitely help them, at least not embarrassing them to be displaced. But the reality is that they can live very well without the help of Wei Dongsheng. Gao Yongqi was promoted to the post of deputy director of the Municipal State Taxation Bureau, and the official road was smooth; the road of You Jinliang's web game was like a fire, with both family and business; even if he fled to Canada Undernet, the little days are also fun. They are all doing well, so why should Wei Dongsheng take care of his business to make them icing on the cake?

The old friendship between Wei Dongsheng and Huo Yongshan is the same. If Huo Yongshan is embarrassed, Wei Dongsheng will pull him within the scope of the law; and now Huo Yongshan, with the profit of Internet cafes, the 100 million US dollars dividend of the Spring and Autumn Network, and the protection of the rights of his father-in-law Dong Heping, has long been a big winner in life envied by the people of Hedong Province. There is no need for Wei Dongsheng to add another zero to his assets.

Wei Dongsheng usually thinks of You Jinliang, boring to read the exchanges between these white hat hackers.

From the perspective of this group of white hat hackers, 2010 was truly an eventful year.

The Patriot missile incident on January 6 just led to a battle of patriotic hackers. At that time, hackers from the US camp hacked many websites in China. Even the Spring and Autumn search was illegally tampered with DNS domain names by hackers, and access failures occurred for about 40 minutes; Hackers from the Chinese camp subsequently counterattacked and hacked many American websites, and Google search was also paralyzed for 4 hours after Spring and Autumn Search. Unexpectedly, the hacker attack and defense war between China and the United States has not yet come to an end. Suddenly, the Avengers group has stolen the NSA hacker toolkit.
