Hacker bitcoin virus ppt

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. There is no relevant regulatory unit and operating rules to rub the edge of the law. Don't rule out the possibility of black background.

4. If you want to dig a good mine, you have to dig deep
first dig a very deep place, preferably more than ten layers above the bedrock, and then, like in the picture, dig a corridor first, and then dig the corridor every two squares in a carpet style. Generally, you can dig some good mines. Also, don't use a low-grade chisel to dig high-grade ore, it won't drop things. Gold and diamond mines can only be g with iron. In addition, please ignore the red ore, red stone in PE version is just useless box.

5. Hello, the anti wana series of blackmailer Trojans introced on the Internet are as follows: first, download and patch to fix the system vulnerability in time; Then close 445 and other ports of network access, this is very important, can greatly prevent the invasion of the blackmailer Trojan horse, specific settings can be found online tutorial, a lot of. Finally, anti-virus software. Generally, our computers don't have anti-virus software. Take Tencent computer housekeeper as an example: turn on the housekeeper's active defense system. It can provide vulnerability defense, active interception, document protection, three layers of security protection, and file black detection, and prompt users to patch and repair vulnerabilities in time. I hope my answer can help you.

For merchants or indivials, the most simple and direct way to realize online payment is to open the online payment interface

the third-party payment platform is no stranger to us. For indivials, from shopping in supermarkets to shopping in markets to buying houses and cars, we live in the scene of third-party payment every day. For businesses, the third-party payment interface plays an important role in raw material procurement, commodity trading, cross-border settlement and so on. Generally speaking, the settlement process of third-party payment platform can be divided into three steps: merchant registration, website filing and website registration. Every step of the process, there are many details to pay attention to

merchant registration

Step 1: registration. Log in to the third-party payment platform you want to register, and register your account according to the platform prompts. If you encounter any problems in the registration, you should contact the third-party payment platform in time. Generally, customer service is online for 7 * 24 hours

Step 2: audit. After the data is submitted, the platform needs time to audit. The audit time of different platforms may be different, ranging from one day to one week. Generally, the notification method is to inform the registrant by email or mobile phone. Take smart payment as an example. With complete information, the audit can be completed in 1-3 working days, and the audit results will be sent by email

however, sometimes the audit fails. At this point, you need to check whether the information submitted to the third-party payment platform is wrong. Generally speaking, there are the following types of audit failure:

1, incomplete data. It includes that the merchant does not fill in the registered domain name, the indivial merchant does not upload the positive and negative sides of the personal ID card, the positive and negative sides of the personal bank card, the bank account information, and the enterprise merchant does not upload the enterprise five certificates (enterprise business license, tax registration certificate, organization code certificate, front and back sides of the enterprise legal person id card, and account opening license)

3. The certificate is not clear, true, complete and invalid

4. The contact person is inconsistent with the certifier

The contact information was invalid

website filing

website filing of third party payment platform generally refers to ICP filing. The so-called ICP filing means that all enterprises, institutions and indivials engaged in non-profit Internet information services should apply to the information instry authorities of provinces, autonomous regions and municipalities directly under the central government for filing proceres, and those websites that fail to file within the time limit will be closed. There is one thing to pay attention to when recording ICP. This access provider can be a service provider of website domain name, and the third-party payment is not an access provider. It is not responsible for dealing with the problem of customer filing. The specific filing process can refer to the following figure:

there are two cases of registering merchants on the third-party payment platform, one is indivial registration, the other is agent addition

1) indivial self registration. Register according to the prompt steps of the third party payment platform. Take smart payment as an example, after successful registration, login according to the merchant number, user name and password sent in the email. After successfully logging into the business management background, upload the five enterprise certificates (business license, tax registration certificate, organization code certificate, both sides of corporate identity certificate and account opening license) and fill in the relevant information according to the prompts on the page. After the merchant completes the background information, the third-party payment platform will notify by email within three working days. Please check the email for the specific results

2) agents add merchants. In the agent management background, click "business management" -- "add" -- improve the business registration information (please select "enterprise" in the process of improvement). After the successful addition, the merchant will receive the email of successful registration. According to the email prompt, log in to the merchant's background to improve the information. The third-party payment platform will give an email reply within three working days after the merchant completes the information
