Blackmail virus event bitcoin

1. In the evening of May 12, the wanna cry worm virus broke out in more than 74 countries around the world. At least 45000 machines have been infected. The network system of some colleges and universities in China has become a disaster area, and the network payment system of PetroChina gas station has also been affected
it is reported that the virus can spread rapidly in the local area network by taking advantage of the vulnerability of port 445 of windows system, but large local area networks such as schools have not done similar prevention, so it has become the target of attack
the success probability of brute force cracking is 0
a person in bitcoin instry said that bitcoin blackmail virus had existed as early as 2014. This time, the technology used by hackers is more high-end than last time, and the scope of influence is wider, but the identity of hackers is still unclear
moreover, the "variability" of this virus lies in the addition of automatic transmission for windows 445 port. As long as the windows system machine fails to upgrade the latest patch, making port 445 open, the virus can invade the machine
the virus requires the intruder to pay $300 worth of bitcoin ransom within six hours, and then the ransom will rise every other time
some netizens pointed out that it is difficult to crack the virus by violence. If bitcoin blackmail virus wants to crack by violence, the possibility is infinitely small, and it is impossible to complete it by virtue of personal ability
port 445 enables users to easily access all kinds of shared folders or shared printers in the LAN
port 445 gives an opportunity for malicious attackers. The normal home network has been limited by the operators to 445 port access, but the school and other large LAN did not do similar prevention, so it became the target of attack
in this virus attack, most of the domestic students who are affected are in Colleges and universities, and the seniors who are about to graate are affected, and the documents related to the design papers are locked. Many universities, including Shandong University, Nanchang University, Guangxi Normal University and Northeast University of Finance and economics, have issued emergency notices to remind teachers and students to take precautions
this virus is more accurately an encryption method. The virus will encrypt all the key files in the computer and make people pay for the unlock password, but whether the hacker will keep his promise and provide the unlock password is his problem
bitcoin blackmail virus has appeared many times
one of the characteristics of this type of virus is to ask the victim to pay bitcoin as ransom. According to many people in the instry, bitcoin is usually used as a tool for cross-border payment and remittance because of its global characteristics. In addition, as a kind of network encryption virtual currency, bitcoin has the characteristics of decentralization and anonymity. The flow of funds is not easy to track, so it is convenient for hackers to make use of its collection and payment, and it is more convenient for them to hide their identities
"if you transfer money to a hacker, you essentially give him a small string of encrypted codes that can be quickly transmitted on the Internet and stored in an electronic wallet." Some people in the instry told reporters that the anonymity of bitcoin is often the reason why computer fans, financial speculators and even drug dealers are fascinated by it
according to the current attacked computers, hackers ask for a ransom of $300 (about RMB 2069.16) worth of bitcoin for each computer
but the area of this virus infection is very large. If everyone pays the ransom, will malicious attackers be able to unlock it in time? Because it is not clear whether the virus will be unlocked manually or online. If it is handled manually, it is likely that it will be too late to handle. However, online processing is fully automatic. After bitcoin has paid, it will automatically collect money and then issue the unlock code
therefore, it is not recommended that the victim pay a ransom to the hacker, because even if you pay, the hacker may not know which computer you have
it is worth mentioning that the outbreak of bitcoin blackmail virus has pushed bitcoin to the top of the wave again. "Bitcoin virus" has become a hot search keyword, and many bitcoin insiders have expressed their concerns about bitcoin's "stigmatization"“ Good tools should not be blamed because they are used by bad people. " A person in the bitcoin instry said, "bitcoin is bitcoin, virus is virus, injustice has a head, debt has owner, so it is unnecessary to have hostility to bitcoin."
now, the most important thing is that the victims should install the patch released by Microsoft as soon as possible to prevent unfamiliar e-mail, and important files should be backed up to the cloud platform and local offline hard disk
wannacry blackmail virus prevention method:
1. Install the latest security patch for the computer. Microsoft has released patch ms17-010 to fix the system vulnerability of "eternal blue" attack. Please install this security patch as soon as possible; For Windows XP, 2003 and other machines that Microsoft no longer provides security updates, we can use 360 "NSA Arsenal immunity tool" to detect whether there are vulnerabilities in the system, and close the ports affected by the vulnerabilities, so as to avoid being infringed by blackmail software and other viruses
2. Close ports 445, 135, 137, 138 and 139, and close network sharing
3. Strengthen the awareness of network security: don't click the unknown link, don't download the unknown file, don't open the unknown email...
4. Back up the important files in your computer to the mobile hard disk and U disk as soon as possible (regularly in the future), and save the disk offline after the backup
5. It is recommended that users who are still using Windows XP and windows 2003 should upgrade to Windows 7 / windows 10 or windows 2008 / 2012 / 2016 as soon as possible.

5. It is recommended that users who are still using Windows XP and windows 2003 should upgrade to Windows 7 / windows 10 or windows 2008 / 2012 / 2016 as soon as possible.
2. Bitcoin extortion virus is basically sent with virus bound, so don't open files with uncertain sources, and back up important files in time. Although the anti-virus effect is not great, we should try our best to upgrade anti-virus and operating system patches in time. These measures are not only to prevent bitcoin virus, but also to prevent more viruses
3. 1、 Before being infected with the virus, you must regularly backup and save the important things in the computer. It's better to prepare another hard disk for regular backup.
2. After being infected with the virus, it's recommended to report to the public security organ immediately for the record, and it's better not to go to the prefecture level or above, county level or below, because as far as I know, many county-level organs are often overstaffed, What is more important is that they basically do not have the relevant technical processing ability and conditions, and many cases may have to be transferred to the higher authorities. As for how the police deal with it, it's out of the question
Third, prepare a new computer. This is the best way to minimize the loss. Never smash the computer or deal with it separately. Instead, you should listen to the arrangement of the police, because if the police are responsible, they may take this as a clue to carry out new detection. On the one hand, it is also a way to eliminate harm for the public, and on the other hand, it may bring some compensation for the loss

4. Wannacry, a blackmail virus, is rampant all over the world, affecting 200000 computers in more than 150 countries. Hackers extort bitcoin worth US $300 (equivalent to RMB 2067) from each computer victim, claiming that the hard disk of the computer will be unlocked only after payment. But it is understood that as of the 15th, hackers have only received bitcoin worth 50000 US dollars (equivalent to 340000 yuan). The blackmail of bitcoin by hackers has no impact on the price of bitcoin. According to the price of bitcoin of okcoin bank, the price of bitcoin was 10639 yuan as of the time of publication
okcoin reminds users that the current domestic bitcoin trading platform does not support extracting bitcoin. If netizens want to buy computers for ransom payment, they need to choose a trading platform that can withdraw bitcoin to avoid a second loss. In addition, after paying the ransom, whether the computer attacked by the virus can be effectively unsealed remains unknown. Therefore, the technical personnel of okcoin currency bank suggest that the majority of Internet users upgrade and install the relevant patches of Windows operating system as soon as possible, and the infected machines should be disconnected immediately to avoid further spread of infection. Users who have not been attacked by virus should update the system as soon as possible, install regular and safe anti-virus software, and improve the defense ability of the computer.

5.
The recent outbreak of bitcoin extortion virus has caused an uproar all over the world. Many people can understand that hackers obtain benefits through virus extortion. However, the strange part of this incident is that hackers demand payment of bitcoin by name. Personally, I don't think this incident is a pure virus blackmail or hacker's network attack, which must also contain an unfathomable purpose of interest
{rrrrrrr}
therefore, I guess that the behind the scenes or the people who started this bitcoin blackmail virus may be the founders and supporters of bitcoin. We should know that bitcoin is far from as good as they boast, and ordinary people will certainly not understand and explore bitcoin, From this we can see that both the value growth of bitcoin in recent years and the bitcoin blackmail virus attack are guided by the founder of bitcoin and its supporters
because if bitcoin can really become a common currency, then these beneficiaries can become banknote printing factories like governments and banks, which is a huge windfall for them
6. I don't think it's the back of the pot
