Latest virus bitcoin 360

1.

Internet security once again because of a large-scale outbreak of computer viruses and caused everyone's attention: bit virus. The emergence of this virus will make the computer's documents locked, hackers to coerce ransom, and most of the places are important units. For example, Chinese universities and British hospitals. The data of these units are very important. Most of the time, the school is not only an ecational unit, many key universities also undertake a lot of scientific research tasks. From a certain point of view, it also shows that hackers are very selective and targeted

Of course, the explanation given by Microsoft said that the virus was an attack against the vulnerability supplemented in March. In a way, hackers are also a test of users' security awareness. Microsoft has added software to the vulnerability in March. From this point of view, the hacker's attack is not brilliant. Because it is through the official patch, and then imagine no patch defects, so as to attack. Hackers also know the update awareness and security awareness of users. Of course, as a domestic company, 360 also seized this opportunity to quickly adjust the security housekeeper to check and kill the virus

from this point of view, Microsoft's vulnerability supplement is targeted and prescient, and the possible vulnerabilities should be supplemented in time

from the user's point of view, this virus attack is different from the previous one. In the past, it is generally in the form of camouflage and loading to ince customers to take the initiative to download. And this time the virus is mostly spread through the LAN, as long as you boot, the virus will invade. The document cannot be opened normally

if this virus attack has any inspiration for us to use computers and pay attention to Internet security, I think it can be inspired from at least two aspects: the first is to strengthen the security of computer systems, such as using official patches to repair vulnerabilities in time; the other is to install regular anti-virus software, update it in time, and strengthen the firewall

2. In the bitcoin virus, 360 antivirus is useless, and even some paid antivirus software can not be used

bitcoin virus (bitcoin Trojan horse) "bitcoin blackmailer" was popular abroad in 2014, and was found in China in early 15 years. This kind of Trojan will encrypt 114 kinds of files in the infected computer, such as docx, PDF, xlsx, JPG and so on, making it unable to open normally, and pop up windows to "blackmail" the victim, requiring the victim to pay 3 bitcoin as "ransom". According to the recent bitcoin price found by the reporter from the Internet, 3 bitcoin is almost 5000 yuan or 6000 yuan. This kind of Trojan horse is generally spread through English mail. The name of the Trojan horse program is usually in English, which means "order", "proct details", etc., and uses fax or form icon, which is very confusing. The recipient easily mistakenly thinks that it is a working file and clicks to run the Trojan horse program.

3. In short, blackmail virus is a computer virus that uses Windows system vulnerability to maliciously encrypt user files and then extort money
