Bitcoin virus paid

1.

Yesterday, I went to the electronic reading room. Not long after I plugged in the USB flash drive, the teacher suddenly asked everyone to unplug the USB flash drive. Some students found that all the files in the USB flash drive could not be opened, and there were two more documents asking for money

so everyone rushed to check, as long as the U disk inserted in the school computer were poisoned, large-scale computer poisoning occurred in the evening

a lot of people's information and graation thesis are in the computer. I really feel that hacker's behavior is disgusting. For the sake of money, regardless of the future of students, teachers' lifelong scientific research achievements...

hope to catch criminals as soon as possible and give them severe punishment by law

this virus will scan windows devices with open 445 file sharing port. As long as the user's device is on the Internet, hackers can implant blackmail software, remote control Trojan horse, virtual currency mining machine and other malicious programs in computers and servers

some security researchers point out that this large-scale network attack seems to be deployed through a worm application, and wannacry can spread among computers. What's more terrible is that unlike most malicious programs, this program can replicate and spread on its own in the network, and most of the current viruses still need to rely on the successful users to spread by cheating them to click the attachment with the attack code

the attack has affected 99 countries and as many as 75000 computers, but because the virus uses anonymous network and bitcoin anonymous transaction to obtain ransom, it is very difficult to track and locate the originator of the virus

The virus in the "bitcoin virus" incident is known as "ransomware". By encrypting the files in the victim's computer, you can't open them completely to ask for ransom. This is a virus attack launched by lawless elements by using "eternal blue" leaked from NSA hacker's weapon library. It does not need any operation of users. As long as it is turned on and connected to the Internet, lawless elements can implant blackmail software into computers and servers

What's more terrible is that this is just the beginning. Now this blackmail virus has spread to all over the world, including many colleges and universities in China. You can see many students on the Internet showing pictures of their computers being attacked. I have to say that hackers are really well intentioned, even in simplified Chinese

3. First of all, turn on the firewall and turn off Port 455. As I said last time, it's easy for you to understand, and it's also easy to understand.

4. Blackmail virus is an encrypted file. If there is no password after being encrypted, you can't see the normal content. After reloading the system, we can only say that there was no virus at that time, and the encrypted files could not see the normal contents. What we can do is to strengthen prevention, make good patches, install anti-virus software and upgrade to the latest virus library. Back up the file to the mobile disk.

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

{rrrrrrr}

therefore, it is not recommended that the victim pay 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 victims should install the patch released by Microsoft as soon as possible to prevent strange mail, and important files should be backed up to the cloud platform and local offline hard disk
