Why blackmail with bitcoin
Publish: 2021-04-11 21:56:32
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.

2. Bitcoin virus (bitcoin Trojan horse) & quot; Bitcoin blackmailer & quot; It 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, so that it can not be opened normally, and pop up the window & quot; Blackmail & quot; Victim, ask victim to pay 3 bitcoin as & quot; Ransom;, According to the recent price comparison of bitcoin found by the reporter from the Internet, 3 bitcoin is about 5000 yuan or 6000 yuan. This kind of Trojan horse is generally spread through English mail, and the name of the Trojan horse program is usually English, which means & quot; Order & quot& quot; Proct details & quot; And use 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
in May 2017, computer network virus attacks have spread to 74 countries, including the United States, the United Kingdom, China, Russia, Spain, Italy, etc.

3. Bitcoin (bitcoin: bitcoin) was originally a kind of network virtual currency, similar to Tencent's q-coin, but it has been able to buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals. In 2013, the U.S. government recognized the legal status of bitcoin, making the price of bitcoin soar. In China, on November 19, 2013, a bitcoin was equivalent to 6989 yuan
