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
network security experts suggest that users should disconnect the network and start up, that is, first unplug the network cable and then start up, so as to basically avoid being infected by blackmail software. After power on, you should find a way to put on a security patch as soon as possible, or install the defense tools launched by various network security companies, so that you can connect to the Internet. It is suggested that the important files in the computer should be backed up to the mobile hard disk and U disk as soon as possible, and the disk should be saved offline after the backup. At the same time, we should be vigilant against unknown links, files and e-mails<

As long as the influence of bitcoin scam is not particularly bad, the government generally adopts the policy that the people do not sue, the officials do not blame, and turn a blind eye to it. Because even if the government enters, it is difficult to find the culprit. The information of some operation teams is not public, and it is difficult to find it on the Internet. Some of them are still abroad, so it is difficult to solve the case. Some of the culprits turn around and become victims. There are also those who participated in the bitcoin pyramid scheme. A large number of victims are also the biggest accomplices< br />

(3) in view of the current technical means, if blackmail virus can not be solved, it can only be completely formatted, Then, the system is reinstalled and the system vulnerability patch is made to prevent the secondary poisoning
it's not that they are not controlled by the makers. On the contrary, when the makers don't want to play, the investors will have nothing left.
in the medium term, with the long-term speculation of bitcoin, some people also realized its value, and some teams began to develop bitcoin technology. In this way, with the passage of time, the technology of bitcoin is perfect, the quantity is rare, the hype is fierce, and bitcoin is sought after by all kinds of gods, so the price will slowly go up
in the later stage, after the implementation of application, promotion and entity trading, people feel that the rise of bitcoin should be taken for granted.
Priority 1 & gt; 2> 3> 4> 5> 6:
1. Main line (a lot of experience, level one must finish)
2. Branch line (a lot of experience, the same main line)
3. Activities (a lot of experience, can catch up as much as possible, and props to)
summary: as the liver emperor, level is definitely the first condition, without level nothing can be done, here is why to build two numbers in the same district, In this test
after finishing the main line and daily routine, you can only get experience by hanging up and brushing monsters, and the two fighting skills are the fastest in all professions, because the fighting skills take a short time
the reason for two fights is that one fight can't clear the monsters in two rounds (in the case of TX magic group, the monsters will have Holy Shield in the first round and weaken automatically in the second round. It takes almost two seconds to hit them)
in the first round, you can't fight to death, and in the second round, you may have too many eggs to clear, so you can cooperate in the last two fights, or you can replace one with a heavy one to make up for the leak. And then all the little friends don't bring (little friends will talk about later) pets also defense, rely on people to fight. The two rounds are absolutely over
then, if you have the conditions, you must hang up and brush the blame. Don't get offline experience. First, offline experience is only favored by people, and then hang up experience is almost twice as much as offline experience
