How to prevent accidental deletion of anti-virus software

 

Today's Internet cafes have become an important place for people to communicate and entertain. However, there are always some people who like to get out of work and try to get online for free in various ways. This will not only harm the security of Internet cafes, but also cause a lot of economic losses to Internet cafe owners, is a very immoral behavior. To prevent Internet cafe users from accessing the Internet free of charge in various ways and cause unnecessary losses to the internet cafe owner, we will serve you todayManagementEmployees are advised to guard against various tips for free Internet access.
Dabing, hacker security technical expert, pays close attention to the trends and developments of hackers and security technologies, advocates and sticks to knowledge openness and technology sharing. For software cracking andNetworkAttack and Defense have unique insights.
Free internet first: out of nothing
The hacker walked through the rivers and lakes and sought free Internet access tips from various schools. He did not dare to share the tips with cainiao. The first trick was "out of nothing ". To change the user database method and enable free Internet access, you must first know the IP address of the Internet cafe host. Click the "run" command in the "Start" menu, enter "gpedit. msc" in the pop-up window, and click OK to open the "Group Policy" window. Click "user"Configuration"Under" manage template"SystemDouble-click the "disable command prompt" option and select "disabled". This allows you to easily break through the command prompt of the Internet cafe management software and the Windows Command LineTools.
Click "run commands" in the "Start Menu", enter "cmd.exe" in the pop-up window, open the Command Prompt window, and enter "ipconfig/all" in the command line of the window ", in the returned information, find the IP address 192.168.0.1 of the Internet cafe host and the IP address 192.168.0.6 of the Local Machine (generally, Internet cafes use intranet-like addresses ). Then run the prepared "ah d NetworkToolkit", Click the" Bot search "command under the" Tools "menu, and set it in the displayed operation interface. First, set "ip" to 192.168.0.1 in the "ip" option on the operation interface, and then click "Start search". The program will automatically crack the account and password of the Internet cafe host. If you are lucky, use the weak password that comes with the "ah d Network toolkit ".SuccessfulCrack the account and password of the Internet cafe host, and then successfully establish an IPC connection with the internet cafe host.
After successfully connecting to the Internet cafe host, click "Win2000 Remote Management" to view some information about the internet cafe host, including system information, system services, users and groups, and shared folders (1 ). Through viewing this information, we can learn some related information, which is called "know yourself, know yourself, and know yourself ". Then upload the configured Trojan program through the program's "grower" function. Click the trojan planting button and set it in the pop-up "Trojan Planting Machine" window. The program has automatically set the host, user name, password, and other options, we only need to click the button after "local file" to select the trojan program to be generated. After the configuration is complete, click the start button, and the program will automatically upload the program to the system of the Internet cafe host, and then run it automatically (2 ).

Start to connect the Trojan's server program. After the connection is successful, findInternet cafe managementProgram directory, and download the database files to the local device. Use a tool to open it. Find your account and modify the account balance. After modification, use the toolManagementAfter the software process ends, copy the modified database file to the database directory of the Internet cafe management software. In the future, we will be able to use this account for free Internet access.
Trick: reinforce the system
There is nothing new about this trick. It can be easily solved by looking at my little "three moves.
First, update the system patch in time. This can prevent hackers from intruding from the Internet, remote overflow of Internet cafe hosts by Internet cafe users through system vulnerabilities, and elevation of permissions on local computers.
Method 2: disable unnecessary system sharing. Many Internet cafe hosts use server-version operating systems. By default, this system enables many systems to be shared. However, these systems are unnecessary for Internet cafe management, but they have many security risks. Therefore, administrators should close unnecessary system sharing as early as possible to avoid convenient access to hackers.
Step 3: Strengthen the password strength of the administrator account. At present, the Administrator account and password of many Internet cafes are too simple, and many or even empty passwords are easily cracked by hackers. It is recommended that the Administrator set the password to more than 8 digits, preferably a combination of letters, numbers and other symbols, which can increase the difficulty of cracking.
Second trick for free Internet access:
If the first trick is "nothing comes out of life", then I will look at my second trick, "Crossing the sea in the sky ". The most common method for free Internet access is to quickly press the CTRL + ALT + DEL key when starting the system, and then terminate the process of the Internet cafe management software. However, this method quickly attracted the attention of software developers in Internet cafes. Therefore, developers adopt different methods to protect their software processes from being terminated by users, for example, the thread Insertion Technology and multi-process technology are used, so that users can easily terminate the process of the Internet cafe management software. In fact, it is better to be wise than a strong attack. Here, we only need to use a tool named "Camera thief" to achieve our goal of free Internet access.
EncounterNetwork ManagementThe software will be restarted immediately after the check-out is down, and you will use the method of freezing the program to achieve free Internet access. The general process is thatNetwork CardWhen the balance is used up, run "On-Demand thieves", set a short period of time, select the "Freeze program" option in "function Selection", and then activate the network management software as the current window. In this way, when the network management software is frozen, your goal will be achieved.
In the event that the network management software will not restart after it is checked off, in addition to the above method, you can also use another method to easily achieve free Internet access. The specific method is to set an appropriate time, select "Run window", and then select "hidden interface" or "brute force cracking" (3 ). Now you can check out and get off the machine. When we set the time, you will see a window showing the desktop icon on the locked computer screen, the following figure shows the free Internet access time.

Trick: Kill "blacksoft"
This trick seems good, but the network management can also be easily resolved.
Step 1: Install the latest version of Internet cafe management software. In addition to fixing vulnerabilities in the software, the new version also provides corresponding methods for cracking.Solution. In this way, it is difficult for users to break through the Internet cafe management software for free Internet access.
Step 2: Install the latest anti-virus software and update the virus database of the software in time. Today, many anti-virus software cracking tools have been blacklisted on the anti-virus software, so anti-virus software can promptly kill these tools that disrupt the order of Internet cafes.
Free Internet access: pay-as-you-go
It seems that I have to do my best, and look at my third move, "pay-as-you-go ". This is a new free Internet access method recently. It is actually by installing a manageable port on the clientNetworkFirewallThen, disable the communication port of the network management software to prevent network communication between the client and the host of the Internet cafe, so that the host of the Internet cafe cannot provide services such as consumption query for the client, we can also achieve free Internet access. However, although billing communication is sometimes blocked, our internet access is also affected. At this time, we only need to adjust the network rules of the firewall.
Breakthrough: when the Group Policy is off
As we call it, you have the technical skills, and I have the trick. Didn't you want to run the firewall? I couldn't let it run. I only allowed the specified program to run and see how you can access the Internet for free. Click the "run" command in the "Start" menu, enter "gpedit. msc" in the pop-up window, and click OK to open the "Group Policy" window. Click "system" in "management template" under "user configuration" to go to the "run only specified Windows Applications" project and select the "enabled" option, then, set the programs that can be run in the "allowed applications list" below. In this way, no program can be used except for the programs I allow.
The so-called "Do not stretch your hand and reach out to be caught ." I suggest you do not do anything that harms your own interests to get online for free.
