The format is simple and to the point:

1. State your identity, which department you work in, and the purpose of the provident fund

2. Write clearly that you have been clear about the relevant provisions of the provident fund and will abide by the provisions and the company's rules and regulations, and ask the leader for approval

2. Application for payment of housing provident fund

3. Take the business license, official seal, code certificate and social security payment notice to the provident fund center.

4. The retirees should withdraw the balance in the employee's housing provident fund account at one time according to the following proceres:
① the employee who meets the withdrawal conditions should first apply to the unit for withdrawing the housing provident fund, and the unit will check whether the employee meets the withdrawal conditions
2. After verification, the company should issue the withdrawal certificate to the staff in time to prove that the withdrawal of the staff is correct
③ when withdrawing the housing provident fund, the employee should also apply to the housing provident fund management center, and provide the retirement approval form and the of the ID card, as well as the valid certificate of the deposited housing provident fund and the application for withdrawal of the housing provident fund
4. After receiving the withdrawal application for housing provident fund and the above supporting documents, the housing provident fund management center will review the deposit of housing provident fund, the supporting documents for withdrawal conditions, and the identity of the applicant, and check whether the certificate provided by the applicant is true, whether the balance is correct, and whether it meets the withdrawal conditions< (5) the housing reserve management center allows the employees to withdraw the housing provident fund and handle the withdrawal and payment proceres immediately.

5. 1. If it is the first time to withdraw, if the down payment is more than 20%, you can take the down payment voucher, house purchase contract, provident fund withdrawal approval form (you need to fill in the provident fund account number, the bank account number of the provident fund issuing bank, for example, if your provident fund is stored in ICBC by the company, you can find a passbook of ICBC at your own will and fill in the account number), ID card, online record form, And then through your company's human resources department approval and seal, you can go to the provident fund center to extract
2. If it's the second withdrawal, you need to bring your house property card, ID card and repayment certificate issued by the bank. You may not have a provident fund card, but you need to know the provident fund account number, and then you can withdraw it in the corresponding bank lending month of the next year. Remember: after the first withdrawal, you can only withdraw it once a year

for specific information, you can go to the local provident fund website for inquiry and consultation. You should also pay attention to how many copies you need and what kind of copies you need. Copying well in advance will help you save time.

6. I was cheated by this too. I've already reported it. Tell general Guohao to get the money back

7. Hacker attack
Open classification: computer, technology, military

--- explanation 1 --------

I. common hacker attack means

hacker attack means can be divided into non-destructive attack and destructive attack. Generally, non-destructive attack is to disturb the operation of the system, and does not steal system data. It usually uses denial of service attack or information bomb; The purpose of destructive attack is to invade other people's computer system, steal confidential information of the system and destroy the data of the target system. Here are four common attack methods of hackers (Note: password cracking is also one of the common attack methods of hackers)

1. Backdoor program
when programmers design some programs with complex functions, they usually adopt the idea of molar programming, dividing the whole project into multiple functional moles for design and debugging respectively. At this time, the backdoor is the secret entrance of a mole. In the program development phase, backdoor is easy to test, change and enhance the mole function. Under normal circumstances, the backdoor of each mole needs to be removed after the completion of the design, but sometimes e to negligence or other reasons (such as leaving it in the program for future access, testing or maintenance), the backdoor is not removed. Some people with ulterior motives will use the exhaustive search method to find and use these backdoors, and then enter the system and launch attacks

2. Information bomb
information bomb is an attack method that uses some special tools and software to send a large amount of information exceeding the system load to the target server in a short time, causing the target server overload, network congestion and system crash. For example, sending a specific combination of UDP packets to an unpatched Windows 95 system will cause the target system to crash or restart; Sending specific packets to a certain type of router causes the router to crash; Send a lot of spam to someone's e-mail to "burst" this mailbox, etc. At present, the common information bombs are mail bomb, logic bomb and so on

3. Denial of service (DOS) is also called distributed d.o.s attack. It uses a large number of packets that exceed the processing capacity of the attacked target to consume the available system and bandwidth resources of the system, and finally results in the paralysis of network services. As an attacker, first of all, he needs to intrude and control a website through conventional hacker means, and then install and start a special instruction on the server that can be issued by the attacker to control the process. When the attacker gives the IP address of the attack object to the process as an instruction, these processes start to attack the target host. This method can concentrate a large amount of network server bandwidth to attack a specific target, so it has great power. In an instant, the bandwidth resources of the attacked target can be exhausted, resulting in server paralysis. For example, in 1999, the University of Minnesota was attacked by hackers in this way

4. Network monitoring
network monitoring is a management tool to monitor the network status, data flow and information transmitted on the network. It can set the network interface in monitoring mode and intercept the information transmitted on the network. That is to say, when the hacker logs in to the network host and obtains the super user permission, if he wants to log in to other hosts, he can log in to other hosts, Network monitoring can effectively intercept the data on the Internet, which is the most commonly used method by hackers. However, network monitoring can only be applied to the host physically connected to the same network segment, which is usually used to obtain the user password< Second, the purpose of the hacker attack. First, the execution of the process. Second, the attacker may only run some simple programs after boarding the target host, or these programs are harmless, only consuming some CPU time of the system
but things are not so simple. As we all know, some programs can only run in one system, but they will not run in another system. A special example is that some scans can only be run in UNIX system. In this case, in order to attack, attackers often find an intermediate site to run the required programs, and this can also avoid exposing their real purpose. Even if it is found, only the middle site address can be found
in other cases, if a site can access another strictly controlled site or network, in order to attack the site or network, the intruder may attack the intermediate site first. This situation may not cause damage to the attacked site or network itself, but the potential danger already exists. First of all, it takes a lot of processor time, especially when running a network monitoring software, which makes the response time of a host very long. In addition, from another point of view, it will seriously affect the trust of the target host. Because the intruder with the help of the target host to the target host can access, and strictly controlled site or attack. When the loss is caused, the responsibility will be transferred to the administrator of the target host, and the consequence is hard to estimate. It may cause the target host to lose some trusted sites or networks. Furthermore, it is possible for the user to transfer a bill to the target host, which is very likely to obtain charging information on the Internet

Second, access to files and data in transmission

the attacker's target is important data in the system, so the attacker attacks by boarding the target host or using network monitoring. In fact, even if the intruder is not sure what time to attack, in general, He will back / etc / hosts or / etc / passwd from the file system in the current user directory< Third, getting the permission of super user means that you can do anything, which is undoubtedly a great temptation for intruders. In UNIX system, it is necessary to have this kind of authority to support the network monitoring program. Therefore, in a LAN, if you master the super user authority of a host computer, you can say that you master the whole subnet< Fourth, illegal access to the system

many systems are not allowed to be accessed by other users, such as the network of a company or organization. Therefore, it is necessary to obtain the right of access by an extraordinary act. The purpose of this kind of attack is not necessarily to do anything, perhaps just for the purpose of access surface attack. In a user network with many windows 95
, many users often share their own directories, so others can easily browse, find things they are interested in, or delete or replace files on these computers. Maybe the act of proving one's own technology through attack is the act of hacking in our imagination. After all, no one likes intruders who specialize in sabotage or bring trouble to others. However, this kind of illegal access to the hacker behavior, people do not like< Sometimes, users are allowed to access some resources, but they are usually restricted by many restrictions. In a UNIX system, without the authority of super user, many things will not be able to do, so with an ordinary account, I always want to get a greater authority. In Windows NT system, there are too many secrets hidden in the system, so people can't stand the temptation. For example, the gateway strictly controls the access of some sites. Many users intentionally or unintentionally try to obtain some permissions that exceed the permission, so they look for the administrator's loopholes in the setting, or find some tools to break through the system's security line of defense. For example, Trojan horse is a means of using multiple users< Compared with the above purpose, denial of service is a kind of purposeful destruction. There are many ways of denial of service, such as grounding the cable connecting the LAN; Sending a large number of meaningless requests to the DNS makes it unable to complete the name resolution requests from other hosts; Create network storm, let the network full of a large number of packets, occupy the network bandwidth, delay the network transmission< 7. Altered information, including the modification, replacement and deletion of important files, is a very bad attack. Untrue or wrong information will cause great losses to users< 8. Exposed information

the invaded site has a lot of important information and data to use. If attackers use some system tools, they will be recorded by the system. If they directly send them to their own sites, they will also expose their identity and address. Therefore, when stealing information, attackers often send these information and data to a public FTP site, or send them to a place where they can get them by e-mail, and then take them from these places later
this is a good way to hide yourself. Sending these important information to public sites results in the spread of information. Because those public sites are often visited by many people, other users are likely to get the information and spread it again< (1)

it should be said that hackers are very smart, but they are not all geniuses. They often use tools and technologies widely used by others in the field of security. Generally speaking. If they don't design their own tools, they have to make use of them. On the Internet, there are many such tools, from Satan and ISS to various short and practical network monitoring tools

in a UNIX system, when the intrusion is completed, the system sets up large and small vulnerabilities. It is very difficult to completely clean up these vulnerabilities. At this time, the system can only be reinstalled. When an attacker listens in the network and gets the password of some users, as long as one password remains unchanged, the system is still insecure, and the attacker can re access the network at any time

for a network, the difficulty lies in boarding the target host. There are many ways to use it when you board it. Even if the attacker doesn't do anything, he can still get important information of the system and spread it out, such as spreading the hosts file in the system. The serious situation is that the attacker will get the following password file on the network for communication. Each tool has its own unique limitations e to its specific design, so from the user's point of view, all the attacks carried out by this tool are basically the same. For example, if the target host is a saprc workstation running SunOS 4.1.3, the administrator may hear exactly the same phenomenon in all attacks using the strobe tool. Understanding these signs is an important aspect of administrator ecation

for a new intruder, he may follow these instructions to attack stiffly, but the result often disappoints him. Because some attack methods are out of date (system upgrade or patching will only waste time), and these attacks will leave traces of attackers. In fact, the administrator can use some tools, or some scripting programs, to let the

8. The other party uses DDoS attack, and penetrates and filters out the computer room, directly hits your server terminal, can CC defense, distributes the other party's traffic packets, so that your server will not collectively drop the card end, or crash

9. This needs to be decided according to your own situation!! Each mole has the same command and different commands
but the super mole hasn't been updated for a long time! Jingyi mole may be updated frequently
but I seldom use moles! Use your own mole! ha-ha

10. Jingyi mole version 2.57 can directly call FTP commands, very convenient, such as FTP_ Create & Directory; 123")
