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

Andrew was only able to operate four of the computers, and the remaining six belonged to two other colleagues who were temporarily absent. Andrew's 4 computers, two of which were not turned on, were not infected with the Bitcoin ransomware virus; A computer that is turned on but has a locked screen, enters the password and returns to the desktop, and the red interface of the Bitcoin ransomware virus does not pop up.

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

If it is only the Internet computer infected with the virus, it proves that the potential threat of the Bitcoin ransomware virus is not strong, at least far inferior to the hacking incident of the previous days.

In the Oahu Cryptography Center branch in Hawaii, the computers responsible for different businesses have different levels of security. Andrew's computer, because of the need to connect to the Internet frequently, from time to time also need to enable special permission to check the background information of Google, Facebook, Titter and other Internet companies, the hard disk rarely stores valuable information for a long time, and many retrieved materials are destroyed immediately after reading. The Oahu Cryptography Center Branch in Hawaii retraced the hacker intrusion incident and found that the Trojan virus released by Wei Dongsheng had already infected many computers, including the physical isolation LAN.

In addition to a large number of hacking tools, the Oahu Cryptography Center Branch in Hawaii stole a lot of important intelligence materials against Russia, China, Germany, Iran, Pakistan, Algeria and other countries. The National Security Agency suspects that the Avengers are a national team hacker organization, or that they have sold a large amount of intelligence information to Russia, China, Pakistan and other countries, and about 4,500 intelligence personnel serving the US intelligence agencies have been leaked. Because in just half a month, more than 100 key intelligence personnel have lost contact, and the potential loss is at least calculated in units of 100 million US dollars.

The Bitcoin ransomware virus in front of me does not infect the computer with the password lock screen, which proves that it has a high probability of instant invasion and instant outbreak, and will not download a large number of files and materials like a hacker intrusion incident. In this case, although the two failures in a short period of time create a sense of humiliation and humiliation, the real loss should be manageable.

The Bitcoin ransomware is indeed less threatening than the hacking incident, but the Bitcoin ransomware is not as simple as Andrew thinks. The worst thing about the Bitcoin ransomware is that instead of damaging your computer system or stealing your data, it encrypts your documents.

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

Ordinary users often lack the habit of backing up files, and can only be dumbfounded and depressed when they find that documents are encrypted. In an organized group like the Oahu Cryptography Center Branch in Hawaii, many documents need to be backed up across computers and servers, which is the vulnerability of the Avengers organization that can steal the NSA hacking kit avengers_group a few days ago, and it is also a security protection mechanism for important documents that are not afraid of being deleted by intruders and encrypted by Bitcoin ransomware.

Under normal circumstances, the Oahu Cryptography Center branch in Hawaii is not afraid of the Bitcoin ransomware.

However, this is not the normal situation at the moment.

The Avengers have released 108 hacking tools for free, and indirectly caused more than 100 key intelligence officers to lose contact, and the US National Security Agency is furious and is also urgently repairing firewall vulnerabilities, replacing all permission passwords, and updating all security services. Such a big project cannot be done in a few days, so many important documents cannot be backed up and deleted immediately, and it takes hours or a day to back up centrally. The bad part is that all of the data that cannot be backed up in real time is encrypted by the Bitcoin ransomware virus.

The Oahu Cryptography Center Branch in Hawaii tried to decrypt it by force, but it quickly turned black.

Wei Dongsheng's version of the Bitcoin ransomware is similar to the Bitcoin ransomware Annacry in 30 years of memory, but the performance has been enhanced. Wei Dongsheng's version of the Bitcoin ransomware annacry_enhanced also adopts a three-level key structure, but the encryption uses the algo01 cryptographic algorithm secretly made by computer intelligent life and supercomputer. The ALGO01 algorithm is used to protect the master secret key to the TK, the ALGO01 algorithm is used to protect the file key FK, and the file key FK is encrypted by the symmetric cryptographic algorithm AES.

Even if Wei Dongsheng uses the asymmetric cryptographic algorithm RSA to protect the master secret key against TK and file key FK like Annacry, the difficulty of brute-force cracking is already unbearable, not to mention the ALGO01 algorithm secretly made by Wei Dongsheng? So to speak. It is the NSA that has the ability to concentrate all the supercomputers in the United States, and with the current computer performance and brute force rate, it is predicted that they will never be able to decrypt the encrypted files of the Oahu Cryptography Center in Hawaii within their lifetime.

Employees of the Oahu Cryptography Center in Hawaii were noisily discussing the Bitcoin ransomware from the impact and technical aspects, when the department leader with the right to call suddenly received a call from the top that the Bitcoin ransomware had broken out around the world.

It turned out that at the same time as the Oahu Crypto Center Branch in Hawaii was attacked, the Bitcoin ransomware virus appeared in North America to South America, Japan to the United Kingdom, and countries around the world.
