With the popularization of ADSL Broadband, many domestic users have entered the Internet era. However, we gradually feel that the speed of K is not fast enough. It would be better if it is faster. When installing broadband, China Telecom's staff will tell you that there are still 1 m and 2 m broadband options, but the cost is very expensive and there is no way to do it. Let's just wait for K.

 
China Telecom's rapid promotion of stars
But now it is different. China Telecom has launched the "Star speed", which is really good. It can be upgraded to 1 Mbit/s of bandwidth for free, which is definitely a pie for many netizens. Apply for installation now. Wow, the speed is quite fast, ...... Why does it not support routing? In the past, two computers in the House had to have only one Internet connection. How can I jump to the sky quickly when I open my browser? Fortunately, China Telecom is a big company, and its services are still good. After the stars are installed quickly, there are a large number of free advertisements on the Internet every day, and some value-added paid services are provided to us, these are forced embedding. All you can do is accept them unconditionally.
 

 

 
 
In the early days, the Internet access method of China Telecom was implemented through third-party software, but there were frequent network problems. It was found that the client was abnormal. In order to improve the network quality, to solve potential user problems, China Telecom has its own plans for dialing programs. Later, the popularity of shared bandwidth made China Telecom very uncomfortable. One dormitory had multiple computers, and only one route was needed to use one broadband account to access the Internet, occupying a large amount of network resources, therefore, China Telecom has the idea of killing routes. Later, the popularity of Bt angered China Telecom. According to China Telecom, 20% of Bt users occupied 80% of network resources, which is intolerable for China Telecom, as a result, China Telecom spent a lot of money to create a "star sky.
 
 

 
In order to popularize "star speed" as soon as possible, China Telecom tries its best to take various measures. For example, in Xi'an, 1 Mbit/s bandwidth is upgraded for free, while new broadband users are forced to install the software. Why does China Telecom spend so much effort to promote the software? Is it to provide users with better broadband quality? In this case, it is estimated that none of the primary school students will believe this. With the speed of the stars, China Telecom will be able to grasp your every action and route? BT? It will be your dream in the future. The purpose of China Telecom is not only embedded advertisements, but also various value-added paid services. In the case of China Telecom, it is to occupy the desktop of the user end.

 
The real purpose of Telecom's rapid promotion of stars
First, let's take a look at the working principle of the star sky speed. The working principle of this software is to encrypt your account and password again before you can log on successfully. That is to say, what you get is not a real password, so you cannot use other pppoe software to dial, even the dial-up software that comes with XP doesn't work. In this way, you will not be able to use the route, and the plan for Telecom to eliminate the route is successful.

 
Your privacy will be invisible
Second, as long as you have installed a starry sky, all your information will be recorded by China Telecom. Privacy does not exist for China Telecom. I remember that Nanjing Telecom once announced that it would charge by traffic, saying that it was used to restrict BT download traffic and improve network quality, but it was criticized by many Parties. Now, as long as China Telecom monitors clients, it is easy to find and limit BT users. When the sky is used, do you still want BT? It's really broken anytime, anywhere.

 
Third, in addition to basic dial-up functions, the starsky express client can also promote and sell other services. The client software runs on the user end, which is the most direct channel from the telecom operator to the target customer group. When the number of users reaches a certain scale, sending ad messages to users through a client and pushing value-added services is the quickest, most effective, and lowest cost method. China Telecom will adopt desktop marketing methods such as "embedded browser Display Marketing page" and "value-added service plug-in button. In this way, we will be forced to "enjoy" the free advertising and value-added paid services provided by China Telecom.

Pppoe is a layer-2 protocol that does not require support from layer-3 IP addresses. Therefore, the broadcast packet captured is the MAC address of the NIC on your computer. The working principle is: the host program starts pppoe dialing, And the pppoe protocol uses the MAC address of the host Nic as the original address. Because the address of the target RADIUS server is unknown, broadcast is adopted, at this time, the adslmodem should be in the rfc1483 bridge mode. It is only responsible for converting the Ethernet signal into a high-frequency digital signal that can be transmitted over the telephone line and transmitting it to the corresponding segment telecommunications server, the peer end is generally a telecom-grade ADSL access device. To put it bluntly, it is a huge adslmodem pool, which converts the received high-frequency digital signal into an Ethernet signal and determines what the data is, when a pppoe dial-up request is sent from the user's network card, the request is sent to the RADIUS Authentication Server, and the server will return the authentication information to the ADSL access device after authentication, to allow the ADSL access device to determine whether to allow the user data to pass through, and return the user's layer-3 IP address and DNS and gateway (this is done by the DHCP server). At this time, the user side receives the returned information, according to the working principle of standard Ethernet, adslmodem is transparent to users.
The first is a batch of iparp broadcasts, not pppoe broadcasts! This ARP broadcast will directly broadcast the MAC address of your Nic to the telecom end. It is reasonable to believe that the telecom bureau can obtain your MAC address and impose MAC address-based restrictions on the port, however, pppoe also broadcasts the MAC address, so this is not the cause for the communication board to find your route sharing. Looking down, there will be 224.0.0.22 IGMP (internt Group Management Protocol) in the network packet capture. This protocol is mainly used to publish information to all the routers and hosts participating in the group! You should understand it here! This is not available in other pppoe software. Therefore, the specification of pppoe dialing in common broadband routers cannot send IGMP requests, in this way, the special servers of the other party can distinguish whether or not you are using the rapid growth of China Telecom. In addition, because the use of dipper is equivalent to adding computers to the IGMP group, the IGMP server will send any information faithfully to all members of the group.
 

For ordinary home users, there may be no things, but for the vast majority of Internet users, the star sky is like various plug-ins on the network, which is very troublesome to use, not to mention those value-added services with free ads and charges. Fortunately, one of our friends on the bear altar found a method to crack the stars quickly and provided a reference here, hoping to help.
 
After learning about how skysky works, we know that upon login, Starsky will encrypt the account password again to generate a new password, therefore, the password can be found through excellent network protocol analysis software to crack the stars quickly. Simply put, it is a process of cracking passwords.
First, we need a network analysis software.

, The size is about 33 MB, with two versions in Chinese and English. Then install Sniffer Pro, install the Chinese patch, and restart the system. Do not run the starry sky to quickly connect to the network, run the program, click "file" --- "Select Settings", select your Nic, and click OK.

 
In step 4, click "Monitor" and "host list" in the menu, and the page is displayed. Click "local" in the figure 2 and "capture" in the Figure 3. Then, you can connect to and run the star network to quickly connect to the network, after connecting to the Internet, you can see four points in the figure, and the telescope has a red dot. Then, click four points in the figure to stop capturing.

Fifth, click decode at 1 in the figure, and a report is displayed. At 2, you can click the serial number of each step, observe the communication records between the local machine and the server, and find your username (marked in red ), password added (black ).
Sixth: Delete the star speed, and use the XP built-in program to dial. Note! Your username remains the same. Change the password to the one you just intercepted.

 
This method is absolutely feasible according to the test. No other problems will occur after the release. A Chinese user provided the method and the test speed was not affected. The only concern is what measures will China Telecom take if there will be a large number of users bypassing the stars to quickly access the Internet?
