Hacker examples explain the analysis method of Trojan horse!

There was a domestic model before, and it had a nice name called "Guangwai Girl". This is the work of "Guangwai Girls" network group of Guangdong University of Foreign Studies. It can run on WIN98, WIN98SE, WINME, WINNT, WIN2000 or Win95/97 with Winsock2.0 installed. Compared with the past, it has the characteristics of smaller volume and more ingenious hiding. It can be expected that in the future, it will become another popular Trojan after the "Ice River".

Address quoted in this article: https://www.eepw.com.cn/article/201706/357346.htm.

Because the method of "Guangwai Girl" is typical, I will explain the research method of general Trojan through the detailed analysis process of this new Trojan. The following test environment is the Chinese version of Windows2000.

I. Tools needed

1.RegSnap v2.80 is the best tool for monitoring changes in the registry and system files.

2.fport v1.33 tools for viewing ports opened by programs.

3.FileInfo v2.45a tool for viewing file types.

4.ProcDump v1.6.2 Shelling tool

5.IDA v4.0.4 disassembly tool

Second, the analysis steps

All the tools are ready, and we begin to analyze this Trojan horse. Once the general Trojan horse runs, it will do some tricks on the registry and system files, so we should make a backup of the registry and system files before analysis.

First open RegSnap, select new from the file menu, and then click OK. In this way, we make a record of the current registry and system files, and if the Trojan horse modifies one of them later, we can analyze it. Save it as Regsnp1.rgs after the backup is completed.

Then we will run the "Guangwai Girl" terminal on our computer. Don’t be afraid, because we have made a detailed backup, and we can change the hands and feet it made as it is. Double-click gdufs.exe, and then wait a moment. If you are running Skynet or Kingsoft Internet Security, you should find that these two programs quit automatically. Is it strange? And listen to our analysis later. Now the Trojan horse is already in our system. Let’s take a look at what it has done to us. Re-open RegSnap, select new from the file menu, and then click OK to save the snap result as Regsnp2.rgs.

Select Compare from the file menu of RegSnap, open Regsnp1.rgs in the First snapshot, open Regsnp2.rgs in the Second snapshot, and select show modified key names and key values in the radio box below. Then press the OK button, so RegSnap will start to compare the two records, and what’s the difference? When the comparison is completed, it will automatically open the analysis result file Regsnp1-Regsnp2.htm.

Look at Regsnp1-Regsnp2.htm and pay attention to it:

It means that in the two records, the registry key was not deleted, 15 registries were modified and one registry was added. Look at the back:

The meaning of this passage is that a new file, diagcfg.exe, has been added under the directory C:WINNTSystem32. This file is very suspicious, because we only ran the Trojan named "Guangwai Girl" between two system information comparisons, so we have reason to believe that diagcfg.exe is the backdoor program that the Trojan left in the system. If you don’t believe me, open the task manager and have a look, and you will find that there is a process of DIAGCFG.EXE, which is the original body of the Trojan horse. But don’t delete DIAGCFG.EXE at this time, otherwise the system will not work normally.

Trojans usually set some key values in the registry so that they can run automatically every time the system restarts. Let’s take a look at which registry keys have changed in Regsnp1-Regsnp2.htm. With experience, we should pay attention to the following:

This key value was changed from the original %1 %* to C:WINNTSystem32DIAGCFG.EXE %1 %*, which is the most suspicious because it contains the Trojan horse DIAGCFG.EXE. So what does this registry key do?

It is the format of running executable file, which was changed to C:WINNTSystem32DIAGCFG.EXE %1. % * After that, run the program C:WINNTSystem32DIAGCFG.EXE every time you run any executable file.

It turns out that this Trojan horse has been tampered with here, so that it can run automatically. Its startup method is not the same as that of ordinary Trojans, which are in

Add a key value to the key, so that you can start yourself, but this method is well known by anti-virus software, so it is easy to be killed. The trojan horse of "Guangwai Girl" is more cunning, and it sets the startup item in another position.

Now that we have mastered the location of this Trojan horse and the startup items in the registry, it is also important to find out which port it is listening to. This can be easily achieved by using fport. Run fport.exe on the command line, and you can see:

We can clearly see that the Trojan horse program is listening on TCP port 6267. So far, we can say that we have mastered all the actions of the trojan horse "Guangwai Girl" in our system, and now we can easily kill it.

Third, killing

After the previous analysis, we have understood the working mode of the trojan horse "Guangwai Girls", and now we will clear it. The following is the method to completely remove the "girl students from Guangzhou". Note: the order of this step cannot be reversed, otherwise the Trojan horse may not be completely removed.

1. Press the Start menu, select Run, enter regedit, and press OK. Open the following key values:

But don’t modify it yet, because if you modify the registry at this time, the DIAGCFG.EXE process will still change it back immediately.

2. Open Task Manager, find the process of DIAGCFG.EXE, select it, and press "End Process" to close this process. Be careful, don’t close the process before opening the Registry Manager, otherwise DIAGCFG.EXE will be started when regedit.exe is executed.

Step 3 put

The key value of is changed from the original C:WINNTSystem32DIAGCFG.EXE %1 %* to %1 %*.

4. At this time, you can delete the DIAGCFG.EXE in the directory C:WINNTSystem32. Remember never to delete this file first, otherwise you will not be able to run any executable files in the system. Since we intend to further analyze this Trojan horse, we will not delete it now, but copy it to other directories for research.

Fourth, in-depth study

We already know the basic working principle, start-up process and how to get rid of it completely, but there is still one thing that we have not completely understood, that is, how it deals with Skynet or Kingsoft Internet Security. To understand this deeply, we must look at the code of "Guangwai Girl". This Trojan has not published the source code, but we can still take a look at it by disassembling it.

The end of "Guangwai Girl" is only 96K, which is obviously encrusted with compression software. We must first determine what shell it has added. It can be detected by using the small tool FileInfo. Now we will copy the DIAGCFG.EXE analyzed in front to the directory of FileInfo, then fi.exe at the command line, and then press Enter, and it will display:

FileInfo has detected that DIAGCFG.EXE has used ASPack v1.06b to shell. Knowing its encryption method, we can use ProcDump to shell it.

Run ProcDump, click the Unpack button, because we want to take off the shell of ASPack v1.06b, so we select Aspack108 in it, and then press OK. At this time, it will let you open the file to be shelled, so we will choose DIAGCFG.EXE and open it. Then wait a few seconds and press "OK". ProcDump will shell DIAGCFG.EXE, and then a dialog box will appear asking you to save the shelled file, and we will save it as gwns.exe.

Note: At this time, the Trojan horse runs on your system again, so it must be cleaned up again according to the previous cleaning steps. Since the cleaning method has been written before, I won’t repeat it here.

Well, now we have got the original file of this Trojan horse before it was shelled. Look at the shelled gwns.exe, which is as big as 194k, which is more than twice as big as the original program. This is the credit of the shelling software. Now you can use the disassembler to disassemble it, and then look at its assembler code.

Let’s use IDA to disassemble it. By the way, this IDA is a super disassembly tool, which is a necessary tool for cracker and Windows hacker. Let’s take a look at some of the disassembled code:

Trojan first loads kernel32.dll, and then uses GetProcAddress to get the address of the API RegisterServiceProcess. Trojan first needs to register itself as a system service, so it is not easy to be found by the task manager when running under Win9x. Then it will GetCommandLineA to get the running parameters, and if the parameters are executable files, it will call Winexec to run.

Then the Trojan will find the process of snfw.exe and kav9x.exe, that is, the process of Skynet or Kingsoft Internet Security, and then kill it.

Trojan will also modify the startup items of "Skynet Firewall" or "Kingsoft Internet Security" in the registry, so that it will not run automatically when the system is restarted next time.

The following is to modify the registry startup item of Trojan horse, namely

Item, so that it can start itself every time the system restarts. Next, the Trojan will initialize Winsock dll, bind the port, and wait for the connection of the Trojan client.

V. Summary

Up to now, we have completed the whole analysis process of the Trojan horse program "Guangwai Girl" and learned about the startup and operation mechanism of the Trojan horse. Of course, the purpose of writing this article is not simply to introduce the Trojan horse of "Guangwai Girl", but to introduce the analysis method of the general Trojan horse through the detailed analysis of this typical Trojan horse. Using the analysis method in this paper, you can completely analyze any unknown Trojan horse variety. Finally, let’s summarize the methods and steps of Trojan horse analysis:

First, the system registry and system files are backed up, then the Trojan server is run, and then the registry and system files that have been run by the Trojan are recorded, and the results of the two records are compared by using registry analysis tools, so that we can know what the Trojan has done in the system. Use fport to view trojan listening port. Then, using the obtained information, the method of removing Trojan horses is made.

If you want to analyze the Trojan deeply, you should also shell and disassemble the Trojan server. In this way, you can fully grasp any action of the Trojan horse. Of course, this requires you to have a good grasp of assembly language and a certain degree of patience, because the lengthy assembly code is not completely readable by ordinary novices.

If you want to further analyze the Trojan message format, use sniffer to monitor the Trojan port, and then make a comparative analysis. This analysis method is more complicated, so this article will not give an example.

Just reading the article is not enough. If you want to fully analyze a Trojan horse, you need to practice it! Good luck!

The combination of theory and practice makes ideological and political course a popular course.

　　Bright picture

　　 The combination of theory and practice is the basic requirement and direction of the "Great Ideological and Political Course" in the new era. The theoretical essence of the "Great Ideological and Political Course" lies in the combination of textbooks and reality, and the unity of theory and practice, which is related to whether the "Great Ideological and Political Course" can be taught with temperature, strength and effectiveness. General Secretary of the Supreme Leader clearly stated: "‘ Great ideological and political course ’ If we want to make good use of it, we must combine it with reality ",emphasizing that" ideological and political lessons should be taught not only in class, but also in social life ". We should thoroughly implement the spirit of the important speech of the Supreme Leader General Secretary, promote the theory and practice of "big ideological and political course" to complement each other, promote the combination of "small ideological and political class" and "big social class", realize the unity of course theory and practice, and accelerate the opening up of a new situation of ideological and political course reform and innovation in the new era.

　　Make the ideological and political course attractive, tense and energetic.

　　 As the main channel of Marxist theoretical education in colleges and universities, "Great Ideological and Political Course" needs theoretical knowledge to enhance students’ understanding of the socialist road, and also needs practical training to cultivate students’ firm and correct political direction. The theoretical knowledge and practical exercise of "Great Ideological and Political Course" complement each other and are indispensable. In the teaching of "Great Ideological and Political Course", there is no pure theoretical knowledge that does not come from practice, and there is no practical exercise that lacks value guidance and theoretical guidance. Only when the theory and practice of "Great Ideological and Political Course" complement each other can the knowledge of ideological and political textbooks be thoroughly explained and turned into students’ conscious thoughts and actions. Promoting the theory and practice of Dali Theory Course complement each other, which has the following three functions:

　　 The ideological and political course is more energetic. The General Secretary of the Supreme Leader pointed out: "The situation at home and abroad and the tasks of the Party and the state are developing and changing rapidly. The teaching content of ideological and political courses should keep up with the times. Only by constantly preparing lessons and constantly talking about innovation can we achieve better teaching results." The great practice of Socialism with Chinese characteristics’s modernization provides a social classroom for the "Great Ideological and Political Course", in which students can deeply experience the historic achievements and changes made by the Party and the country, such as the Party leading the people to complete the great historical task of getting rid of poverty in the new era and leading the people throughout the country in their immortal struggle against the COVID-19 epidemic. Vivid practice and vivid reality are magnificent and boundless, which contain the source of theory, the foundation of belief, the degree of right and wrong and the root of feelings, and are the vivid teaching materials for the teaching of "Great Ideological and Political Course". These vivid and vivid "ideological and political textbooks" inspire the enthusiasm and initiative of young people in the new era to build the cause of Socialism with Chinese characteristics, strengthen their political stance and struggle confidence, and encourage young people in the new era to write life chapters in the vivid practice of realizing the Chinese dream.

　　 The ideological and political course keeps the tension more. General Secretary of the Supreme Leader pointed out: "Students will ask some sharp and sensitive questions in ideological and political classes, which often involve deep-seated theoretical and practical problems. It is not easy to make these questions clear and thorough." The construction of "Great Ideological and Political Course" needs to start from students’ concerns, focus on the goal of cultivating people by virtue, and respond effectively to students’ needs and concerns according to the unprecedented changes in the world, the overall development of the cause of the party and the country, and the vivid practice of the Communist Party of China (CPC) leading the people to govern the country, such as the dynamic follow-up teaching supply.

　　 The ideological and political course is more charming. General Secretary of the Supreme Leader pointed out: "Run the ideological and political course well … … Consciously integrate patriotism, ambition to strengthen the country and serve the country into the struggle to uphold and develop Socialism with Chinese characteristics, build a socialist modernization power and realize the great rejuvenation of the Chinese nation. " In the "Great Ideological and Political Course", the national political prosperity, economic and social events and people’s livelihood happiness are not only the distinct requirements of the "Great Ideological and Political Course", but also the outstanding features of the "Great Ideological and Political Course". The "great ideological and political course" is not the size of the classroom or the theoretical knowledge. No matter how large the class is, no matter how rich the theoretical knowledge is, it can’t be called big if it is placed between the vast world. We should regard the magnificent practice as an ideological and political classroom, so that students can feel the awe-inspiring righteousness between heaven and earth, let them take the initiative to feel the practice, explore the essence of things, grasp the law of development, and let the truths, principles and things that students have realized in practice be preserved after many years. Teachers of ideological and political courses should have a solid foundation, be flexible in various ways, respond to students with thorough theoretical analysis, and convince students with thorough ideological theory, so that students can be convinced and benefit for life. Only in this way can the ideological and political course become a "hot class" or even a "bursting class" full of charm.

　　Break through the barriers between "ideological and political classroom" and "social classroom"

　　 In recent years, colleges and universities all over the country have actively opened up the way of combining theory and practice of "Great Ideological and Political Course", constantly breaking through the barriers between "Small Ideological and Political Class" and "Big Social Class", and explored the following important ways of combining theory and practice of "Great Ideological and Political Course":

　　 The first is to strengthen the top-level design of the construction of "Great Ideological and Political Course" and promote the combination of theory and practice. It is an inevitable requirement to promote the construction of "Great Ideological and Political Course" to make concerted efforts by the party and government and strengthen the top-level design. As the first person in charge of the construction of "Great Ideological and Political Course", the party secretary and president of colleges and universities need to take the lead in attending lectures and investigating, take the lead in promoting the construction of "Great Ideological and Political Course", and establish and improve the working mechanism in which the academic affairs department and the teachers’ work department take the lead, the colleges (departments) are specifically responsible, and the publicity and personnel departments directly participate.

　　 Marxist College and other relevant departments should integrate the ideological and political resources of the whole school, coordinate the work of the "Great Ideological and Political Course" in the school, combine the characteristics and advantages of the school, constantly update the teaching content, constantly innovate and improve the teaching methods, be good at adopting various teaching methods such as case teaching, inquiry teaching, experiential teaching, interactive teaching and focus teaching, and actively use modern information technology to make the ideological and political course alive.

　　 The second is to promote the combination of theory and practice by means of social practice and other forms. General Secretary of the Supreme Leader emphasized that "all knowledge must be put into practice if it is to be transformed into ability. We must adhere to the unity of knowing and doing, pay attention to learning true knowledge and understanding the true meaning in practice, and strengthen our ability to hone and grow. " Social practice is just responding to this call, and it is an important way to transform theoretical knowledge into action practice. Guide students of different grades and stages to participate in practice and sharpen their growth. Through social practice, we can recognize the national conditions, increase our talents, exercise our perseverance and contribute to society.

　　 Students turn what they think and learn into concrete actions through practical forms such as investigation of national conditions, social service, learning and preaching, aiding border education, and scientific research practice. It can not only understand the society in multiple dimensions, improve practical skills, but also solve some concrete and practical problems. At the same time, colleges and universities should encourage and fund practical members and even ideological and political teachers to give theoretical lectures at the grassroots level, advocate practical teams to hold discussions with staff of grassroots people’s governments, enhance students’ sense of social responsibility and historical mission, and effectively guide young students to be firm believers, active communicators and model practitioners of socialist core values. Through the organic combination of ideological and political courses and practical courses, students are guided to put their life ambitions into down-to-earth practical actions, and the specific goals of study and struggle are combined with the great goals of national rejuvenation.

　　 The third is to promote the combination of theory and practice through various scientific research projects and competitions. The development and promotion of scientific research projects and competitions can purposefully promote the organic combination of theoretical knowledge and practical exercise. It is necessary to highlight the realistic orientation and problem orientation of scientific research projects and competition results, and to refine the practices and experiences in the process of promoting projects and competitions into theoretical knowledge. For example, the National Challenge Cup, internet plus Competition, "Creating Youth" Competition and Red Brigade Special Competition are important platforms for integrating the theory and practice of "Great Ideological and Political Course", and integrating ideological and political elements such as family feelings, public service, innovation and entrepreneurship will greatly improve the quality and effect of scientific research projects and competitions.

　　 At the same time, by enriching the ideological and political content of scientific research projects and competitions, the concept of "Great Ideological and Political Course" is extended to many aspects such as project declaration, competition planning, activity design and achievement evaluation, so as to improve the effectiveness and appeal of ideological and political education and realize the organic unity of "scientific research ability improvement" and "value guidance". On the basis of fully understanding the characteristics of scientific research projects or competitions and related professional knowledge, we should dig out the points of combination with China’s excellent traditional culture, the major policies of the party and the state, and the socialist core values from the knowledge units closely related to scientific research activities and competitions. The team should be good at embodying and displaying the corresponding highlights of ideological and political elements, so as to make the integration process "flexible and vivid", which can not only enhance the realm of scientific research projects and competitions, but also enhance the practice of ideological and political education.

　　 The fourth is to build a multi-dimensional evaluation system for the construction of "Great Ideological and Political Course" and promote the combination of theory and practice. To build a multi-dimensional evaluation system for the construction of "Great Ideological and Political Course", it is necessary to set up concrete and operable evaluation indicators, including curriculum construction planning, ideological and political ideas, teaching methods and teaching means reform, evaluation methods, teaching achievements and application promotion effects. To improve the quality and effect of the construction of "Great Ideological and Political Course", it is necessary to strengthen the process management of "Great Ideological and Political Course" and highlight the characteristics of regularization, institutionalization and standardization of the construction management of "Great Ideological and Political Course".

Ministry of Ecology and Environment： In 2017, the air quality of 99 cities at prefecture level and above reached the standard.

　　CCTV News:Today, the Ministry of Ecology and Environment released the Bulletin on Ecological Environment in China in 2017: In 2017, the quality of atmospheric and water environment in the whole country was further improved, the risk of soil environment was contained, the pattern of ecosystem was generally stable, and the people really felt the positive changes in the quality of ecological environment.

　　The quality of air and water environment in China has been further improved.

　　The communique shows that the blue sky defense war has achieved remarkable results. The average concentration of PM10 in 338 cities at prefecture level and above decreased by 22.7% compared with 2013.The average concentration of PM2.5 in Beijing-Tianjin-Hebei, Yangtze River Delta and Pearl River Delta regions decreased by 39.6%, 34.3% and 27.7% respectively compared with 2013.,The average concentration of PM2.5 in Beijing dropped from 89.5 μ g/m3 in 2013 to 58 μ g/m3.The air quality improvement objectives and key tasks of the Air Pollution Prevention and Control Action have been fully completed.

　　Increase the intensity of water pollution control. The proportion of excellent surface water quality sections in China has been increasing.The proportion of I-III water bodies reached 67.9%, and the proportion of inferior V water bodies decreased to 8.3%.The water quality of the main stream of major rivers has improved steadily.The black and odorous water bodies in the built-up areas of 36 key cities have been basically eliminated.All the 490 environmental problems identified by drinking water sources in cities at the prefecture level and above in the Yangtze River Economic Belt have been cleaned up and rectified.

　　Central environmental protection inspector solves a large number of environmental problems

　　According to the 2017 Bulletin on Ecological Environment in China, in 2017, the national environmental supervision and law enforcement was continuously strengthened, and the third and fourth batches of inspectors from 15 provinces were completed, which achieved the full coverage of the first round of central environmental protection inspectors and promoted a large number of environmental problems to be solved.

　　According to the communique, during the inspector’s presence, the central environmental protection inspector held more than 18,000 party and government leading cadres accountable.Accepted 135,000 environmental reports from the masses, and directly promoted the solution of more than 80,000 environmental problems around the masses.. Among them, special supervision was carried out on the ecological problems of Qilian Mountain National Nature Reserve in Gansu Province, and 11 cadres with leadership responsibilities, including 3 middle-ranking cadres, were seriously accountable. At the same time, strengthen the supervision of environmental protection, and interview 30 cities (counties, districts), departments and units in 2017; Regional restrictions were imposed on cities such as Linfen, Shanxi Province, and the atmospheric environmental problems in Langfang, Hebei Province were listed and supervised. Typical cases such as poor rectification of Nantong inspectors in Jiangsu Province and serious air pollution in Heilongjiang Province were carried out with mobile and acupoint-type special inspectors.

　　In 2017, we will continue to carry out the annual activities for the implementation of the Environmental Protection Law, severely investigate and punish human interference with environmental monitoring, carry out the special action of supervision and inspection of the "Green Shield 2017" national nature reserve, investigate and deal with violations of laws and regulations, and steadily promote ecological protection.

　　There are still 70% cities whose air quality is not up to standard.

　　In 2017, the quality of the national atmospheric environment was further improved, but 70% of the cities still failed to meet the standards, and the overall situation was still not optimistic.

　　According to the current air quality standards, that is, the average annual concentration of PM2.5 is not more than 35 μ g/m3, PM10 is not more than 70 μ g/m3, and other comprehensive indicators of six pollutants such as sulfur dioxide and nitrogen dioxide,In 2017, among the 338 cities at prefecture level and above, 99 cities met the air quality standards, 239 cities failed to meet the standards, and 70.7% cities failed to meet the standards.In 2017, the average annual concentration of PM2.5 in 338 cities nationwide was 43 μ g/m3, and the average annual concentration of PM10 was 75 μ g/m3, which still exceeded the standard.

　　According to the comprehensive air quality index evaluation, in 2017, among the 74 cities where the new standards were monitored and implemented in the first phase,The ten cities with relatively poor air quality are: Shijiazhuang, Handan, Xingtai, Baoding, Tangshan, Taiyuan, Xi ‘an, Hengshui, Zhengzhou and Jinan.The ten cities with relatively good air quality are Haikou, Lhasa, Zhoushan, Xiamen, Fuzhou, Huizhou, Shenzhen, Lishui, Guiyang and Zhuhai.

　　Surface water generally improves the stability of coastal seawater quality.

　　According to the 2017 Bulletin on Ecological Environment in China, in 2017, the surface water in the whole country improved, the quality of coastal seawater remained basically stable, and the water quality level was average.

　　Among the major rivers in China,The water quality of the rivers in the northwest and southwest is excellent, the rivers in Zhejiang and Fujian, the Yangtze River and the Pearl River Basin are good, the Yellow River, Songhua River, Huaihe River and Liaohe River Basin are slightly polluted, and the Haihe River Basin is moderately polluted.Of all the 1617 water quality sections, the first-class water quality section increased by 0.1 percentage points over the previous year, while the fifth-class and inferior fifth-class water quality sections decreased by 1.1 percentage points and 0.7 percentage points respectively.

　　Among the 112 important lakes (reservoirs), there are 70 with water quality of I-III, 22 with water quality of IV, 8 with water quality of V, and 12 with water quality worse than V. The main pollution indicators are total phosphorus, chemical oxygen demand and permanganate index.

　　Water quality in coastal waters,The Bohai Sea is average, the Yellow Sea is good, the water quality in the East China Sea is poor and the water quality in the South China Sea is average.In the important estuaries and bays, compared with 2016, the water quality of Jiaozhou Bay and Minjiang Estuary has improved, the water quality of Yellow River Estuary, Pearl River Estuary and Beibu Gulf has deteriorated, and the water quality of other estuaries and bays has remained basically stable.

Why hasn’t Huawei P70 been released yet？ What is it waiting for？

Everyone is still waitingHUAWEI P70Anyway, I can’t wait any longer.

How popular the Huawei Mate series and P series are, it can be said without further ado. Far from saying, when the Huawei Mate 60 series was just released last year, the whole network was talking about this new "suddenly" emergingcell phoneMany people couldn’t buy it for a few months, and they were still queuing up for delivery until the end of last year. What’s more, they didn’t hesitate to spend more money just to be able to "enjoy" in advance.

Why hasn't Huawei P70 been released yet? What is it waiting for?

This year’s P series is no exception. As long as there is a wind and grass in the past few days, Huawei P70 will be on the hot search. For example, the day before the Xiaomi SU7 conference, the hot search is "Huawei P70".

Hot search is enthusiasm, and everyone’s enthusiasm is high, nothing more than this one thing: "Today is a suitable day, it’s time to release".

In fact, only the staircase rang, but no one came down. Before that, Huawei had launched new products for five consecutive days, including yesterday’s Huawei Hongmeng Spring Communication Conference, which also released a new smart world S7, notebook and new earphones. Only the Huawei P70 has not yet been confirmed.

We can’t help but ask, is this phone still being sent? This state of "still holding a pipa and half covering your face" can whet everyone’s appetite.

Why hasn't Huawei P70 been released yet? What is it waiting for?

Huawei P70 is constantly out of the loop, and in the end, Huawei is too popular. As the flagship of Huawei’s P series, this phone will not be weak. First of all, in terms of imaging, it is rumored that Huawei P70 Standard Edition and Huawei P70 Pro will use the main camera of the Howei OV50H sensor, while Huawei P70 Art will use the main cameraSonyIMX989 one-inch main camera, these two sensors are also our old acquaintances, blue and green factories and Xiaomi are using, although the parameters are not as good as the new LYT-900 sensor, but considering the advantages of Huawei’s computational photography, the combined XMEGA imaging strength of the two is still not to be underestimated.

As for telephoto lenses, there wasn’t much news yet, but the previous generation’s super-light-focused night vision telephoto was pretty good. It supported telephoto macro and had good anti-shake performance. This generation had to be upgraded more or less… right?

According to the same source, the standard version has a screen size of 6.58 inches, while the Pro and Art have a screen size of about 6.8 inches, both of which have a 1.5K resolution. I hope to use the Huawei Mate 60 series of four-curve screens, which have the best grip of all the widescreen phones I have ever used.

In terms of chips, there was still not much information to refer to, which was expected. However, the possibility of a chip upgrade was very low, after all, the cycle was very short, and the P series and Mate series had always been the same in terms of processors, so the probability was still the Kirin 9000S.

Other configurations, such as generative AI, Beidou satellite communication, Tiantong satellite communication, variable aperture, new Hongmeng system, high-density battery, Xuanwu architecture, Kunlun glass and other functions and highlights are also essential. If not, then you can wait for the Huawei Mate 60 series!

So far, the most reliable thing about the exposure of the Huawei P70 is the exterior design.

After yesterday’s Huawei Hongmeng Ecological Spring Communication Conference, a suspected photo of the back case of Huawei P70 standard appeared on the Internet. From the photo, the rear camera module is triangular design, which is quite recognizable, which seems to confirm the previous exposure.

In addition to the standard version, the design of the P70 Art is very "artistic". It is reported that the rear camera module is designed with irregular polygons. Although it is different from the previous generation, the tone has not changed at all, and the credibility is still very high.

Overall, the Huawei P70 series has been exposed in all aspects, but the substantive content is not much, so the small partners cannot be fully trusted. It is more reliable to wait for the press conference.

As for why the phone has not been released and officially announced, it is more likely to wait for another opportune moment. In the mobile phone industry, the release time of the product is not randomly selected. As a global leader in mobile phone manufacturing, Huawei’s new product release is particularly eye-catching, and the relevant release plan is bound to take into account the complex market environment and internal conditions.

For example, adjust the configuration, price, and marketing strategy of their own products to ensure that the P70 series can stand out among many competitors as soon as it enters the market.

Or polish the product finer. whether it issoftwareThe optimization and stability of the system can be further refined, and strict quality control can also enhance the user experience, allowing everyone to buy with greater confidence.

Finally, not announcing the specific release time also gives Huawei more time to do marketing and promotion. On the day of the actual release, the P70 series became popular on the whole network and sold well.

Of course, the premise of all this is that Huawei has sufficient strength and confidence, and judging from the performance of Huawei Mate 60, there is no doubt about this.
