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!

On barrier-free design： the secret of blind people playing smart phones happily

If you, as a product manager, were to design a smart phone for the blind, what would you do?

It is nothing new for blind people to use mobile phones. In the era when Nokia was still dominating traditional mobile phones, they could play their mobile phones as smoothly as normal people through physical buttons and voice prompts, and it was no problem to listen to music and make phone calls. Even with a huge base, the blind are still a marginal group, and it is difficult for them to enjoy the fun brought by intelligent technology like normal people.

There are many kinds of mobile phones for the blind in the market. Mobile phone manufacturers are following the product concept of "less is more", removing useless modules and highlighting core functions.No screen, multiple buttonsIt has become the "standard" for blind people’s mobile phones. Even if you go out with a mobile phone as ugly as a TV remote control, Who care? I can’t see it anyway, just use it.

However, simply relying on voice broadcast to exchange information can’t solve the contradiction between the blind people’s yearning for a better life and the single function of the special machine. And the barrier-free design in smart phones, with a bang, brought them Marxism, ah no, it brought them "a pair of eyes". In the jargon of our products, the special machine for the blind is the superficial demand-a faster horse, while the barrier-free service in smart phones is the train and car, which solves their deeper needs.

Barrier-free is relative to "disabled" people, which is what we often call disabled groups. Since the era of special machines for the blind, information barrier-free technical services have always been around.Phonetic assistanceWith the development of this core function, the blind can get voice feedback by touching physical keys, thus guiding further operation. But today’s mobile phonesThe screen is getting bigger and bigger, and there are fewer and fewer buttons.Without a comprehensive screen, I am embarrassed to open a press conference. Everyone can’t wait to make the screen ratio the ultimate 100%. Chopin of B can’t play the sadness of the blind, but the information barrier-free technology of B has given this "useless" screen a new historical mission.

The two heroes, Android’s TalkBack and Apple’s VoiceOver, make the blind finally use the mobile phone screen, and the more they use it, the smoother it is! Blind people touch the screen and use different interactive gestures to identify the current content and perform functional operations through screen reading.

Instead of exquisite visual animation and flat design style, the focus of interaction falls on physical gestures. For example, normal people’s interactive operations such as "click to enter", "long press and drag" and "slide to cut the screen" on the mobile phone are all redefined in the barrier-free auxiliary mode, so blind people can use various program services more deeply without relying on the physical buttons of the mobile phone.

Take Apple’s mobile phone as an example. You can turn on or off the VoiceOver service in "Settings–General–Accessibility", and the interactive gestures of the mobile phone will change after turning on. Taking opening an APP as an example, the normal operation is to directly click the icon of the APP. However, in this mode, in order to prevent the blind from touching the APP by mistake, clicking the icon of the desktop APP will only read the name of the APP, and the blind will open the APP by double-clicking the screen when they touch the app that needs to be opened one by one through voice feedback. Looking at this text description alone, I already feel that the operation is cumbersome, but these new interactions have given them unlimited possibilities.

Although mainstream aesthetics runs counter to the actual needs of the blind, thanks to barrier-free design, the scenes of blind people using smart phones are enriched. Starting from scenes and user portraits, it solves the pain points of how blind people use smart phones, which is equivalent to solving most of the pain points in their lives:

Difficulties in traveling-insufficient blind road facilities, greatly affected by the weather, and scarce guide dogs;

Corresponding plan: travel apps (such as Didi, Shenzhou special car, using express car and other travel modes)

Social difficulties-narrow communication circle, daily access to information only by listening to the radio, and single information channel;

Corresponding solutions: news & social apps (such as WeChat, QQ, various news clients, voice chat or listening to news).

Difficulties in shopping-it is difficult to identify the authenticity of banknotes, and buying goods is easy to be stolen and shoddy;

Corresponding plan: shopping apps (such as Taobao and JD.COM, through voice search, you can buy various items without leaving home to solve the payment problem).

……

You don’t have to visit users, investigate the market, and try to figure out the product positioning and direction. Any analysis can dig out a lot of pain points in blind people’s lives, and each pain point seems to have corresponding APPs to "relieve pain". However, barrier-free service is not a panacea for blind people to use smart phones, and there are often embarrassing scenes with full ideals and skinny reality.

After the author’s experience for a period of time (my eyesight is normal), I will share with you the pit in the process of using the mobile phone barrier-free service.

I believe many people will feel dizzy when they see this picture, let alone people with visual defects. The verification code often appears at the entrance of websites, software or services. As a tool to verify identity, blind people who are stuck at the entrance are disqualified from normal use, and the unreadability of pictures makes the screen reading function useless. The most famous case is that the verification code of 12306 website (which doesn’t explain what you know) was brought to court by a blind person. Although it ended in the blind person losing the case, the verification code problem that plagued the blind person’s operation can no longer be ignored.

Voice verification code is a better solution, although its original intention is not for the blind, like some take-away apps will be used when registering. Due to cost and technical reasons, this service has not been used on a large scale. In addition, the general SMS verification code also meets the screen reading requirements of the system. The difference in user experience between PC and mobile also makes more blind people rely more and more on mobile phones.

Due to their own physical conditions, the education level of the blind is generally not high, so the input method has become a threshold for them to use smart devices. They haven’t learned five strokes, can’t pinyin, and can only write some simple words by hand, which leads them to stumble when using traditional input methods. The input process is full of difficulties and the output words are full of mistakes and omissions. After the simulation experience, I suddenly realized that the original "goddess" chat mode is such a thing: others say ten sentences, and you only reply slowly.

Since the emergence of voice chat applications like WeChat and the rise of various intelligent voice recognition input methods, this pain point has been well solved, which not only facilitates most "lazy people", but also relieves the urgent needs of the blind. I’m trying to read a short passage of about 100 words by using Iflytek’s voice input method. The speed of synchronous input and voice recognition is very fast, and the accuracy of words is over 99%. Of course, this is also limited to the reader’s Putonghua level. I believe that the development of artificial intelligence will make the recognition rate higher when the voice input method is used.

Android is a little girl who can be dressed up at will. Large mobile phone manufacturers will build their own customized Android system, and all kinds of ROM packages on the Internet are flying all over the sky. In order to pursue the simplification and smoothness of the system, some people often castrate most of the built-in services, including accessibility, while satisfying most of the target groups, they accidentally hurt this small group of vulnerable people, making the blind get a carefully "optimized" "brick" machine, which is useless. However, Apple has not lost in this aspect of the system and maintained its due conscience.

For normal people, even with the golden key of barrier-free service, after practical operation, it is found that there are actually many hurdles to be crossed. It is hard to imagine how blind people can play mobile phones happily with us. Everyone is joking that poverty limits their imagination, but after reading a set of real data, I find that my imagination is actually limited by prejudice.

According to the Basic Information Report of Internet Visually Impaired Users in China released by the Secretariat of China Information Accessible Products Alliance (CAPA) in 2016, China has13 millionVisually impaired people, among the surveyed users of visually impaired people, there are92%While using smart phones, 22% of the visually impaired have used Internet software such as Didi, Kuaidi and uber taxi to take a taxi, 33% of the visually impaired have installed 11 to 20 applications on their mobile phones, and 83% of the visually impaired are operating their mobile phones and computers.Can be completely relied onScreen reading function.

Lovely and respectable products and technicians did not limit their imagination to mainstream design, but turned "waste" into treasure, turning the mobile phone screen that was useless to the blind into the best entrance to enjoy intelligent services. Although there are still many pits in the barrier-free product experience, more and more manufacturers are gradually aware of the existence of this special group. For products like BAT, barrier-free details are finely integrated into QQ and Alipay, which may not be noticed by normal users because we are not the "target group".

Although the target group always excludes blind users by default in the process of our product analysis, and the benefits created by 1% special users seem to be so insignificant for a product that meets 99% normal users, with the development, China’s Internet information accessibility level is gradually improving, and more products begin to examine their own barrier-free user experience design, opening up a green information channel for visually impaired people to integrate into the mainstream society.

Maybe one day, a blind man will come to me and say:

"Hey, I’ve used your product, it’s really good!"

It has solved the pain points of users, realized the benefits of products, and fulfilled the social responsibilities. As the glory of product people, this is much Cool.

Double 11 is a little ＂cold＂？ Don’t sing down yet.

　　Big data shows that 15-year-old "double 11" is a bit "cold".

　　According to Baidu Index, the search index of "double 11" was on the rise from 2011 to 2015, and it basically maintained its popularity in 2016, but it dropped significantly in 2017, only slightly rising in 2019, when live e-commerce rose, and then falling all the way, making 2022 the coldest "double 11" in the past 10 years. It should be said that this year’s "double 11" heat is slightly higher than last year, but judging from the trend, its highlight moment has passed.

Double 11 is a little "cold"? Don't sing down yet.

　　Baidu index screenshot, provided by the author.

　　From the outside, after the rise of live e-commerce and social e-commerce, strategies such as anchor welfare and 10 billion subsidies have made low prices run through the year. Statistics show that two-thirds of Tmall’s days in a year are shopping festivals, and consumers have long been "desensitized" to big promotions; From the inside, the negative impression of false promotions such as raising prices first and then lowering prices, and getting together for half a day is only one yuan and eighty cents cheaper, has killed consumers’ passion and trust in big promotion. If we catch up with some consumers who are not well off, it will inevitably get cold.

　　However, this does not mean that "double 11" is completely cold. Besides big data, there is another hot "double 11"-

　　There are more and more participants. This year, JD.COM Live and Xiaohongshu e-commerce have entered the market, and the record is good. Take Xiaohongshu as an example. During the "double 11" period, the number of e-commerce orders of Xiaohongshu was 3.8 times that of the same period of last year, and the amount of powder broadcast in stores was 14.2 times that of the same period of last year.

　　The value brought to businesses is becoming more and more accurate. Take Tmall as an example. As of 0: 00 on November 11th, Taobao Tmall has brought more than 100 million new members to merchants, and the turnover of 38,000 brands has increased by more than 100% year-on-year.

　　Some consumers don’t pay attention on the surface, but their actions are sincere. According to the data of the State Post Bureau, from November 1 to 11, the national postal express delivery enterprises collected 5.264 billion express parcels, a year-on-year increase of 23.22%.

　　The figures show that "double 11" is still the most important outbreak period of various brands in a year, and it is the training ground with the most concentrated infrastructure such as supply chain, cloud service and logistics. Today’s "double 11" peak may be the norm in the future. "double 11" has been transformed into a "concern war" and a "value war". Every November, people always think about whether to buy something. For this reason, "double 11" should not be underestimated.

Double 11 is a little "cold"? Don't sing down yet.

　　Among all the data, there is a set of data that deserves special attention: this year, in double 11, there are 1,606 new brands that have opened stores in Tmall for less than three years, winning the champion of new trend category, which means that as long as consumers are treated with care, there will be a lot of market opportunities. In Xiaohongshu, there are also 30 brands located in the new track, and their products cover furniture, accessories, bags, new Chinese clothes and so on. Tracks are constantly emerging and brands are changing rapidly. Such a market is full of vitality and the competition is extremely fierce.

　　However, no matter how difficult it is, there is still a chance. Apart from China, it is hard to imagine any other market that can breed so many new brands in a short time. This is the resilience of China’s economy, and it is also the strength of a consumer market with a population of more than 1.4 billion.

　　There’s no need to talk bad about "double 11" now. Even at the end of the attention cycle, there is a long tail effect.

　　How "double 11" behaves next depends on itself. This year, the General Administration of Market Supervision once again issued the "double 11" Guide to Promoting Compliance, emphasizing nine aspects, such as eliminating price fraud, strengthening advertising review, preventing counterfeiting and resolving consumer disputes, which can be called the "longevity guide" of "double 11". "double 11" should be able to accompany consumers in China for several years if we can listen to users’ voices, resolutely implement regulatory regulations and firmly guarantee quality services.

Check the pickup trucks with fuel-saving mode from the source

At 24: 00 on March 17th, a new round of domestic refined oil price adjustment window was reopened. According to the news of the National Development and Reform Commission, the domestic gasoline and diesel prices increased in 750 yuan and 720 yuan respectively per ton. After the price adjustment, the No.95 gasoline has exceeded 9 yuan per liter. Adding to a price increase at the end of December last year, the domestic refined oil price has risen for six consecutive years, and the cost of car use for migrant workers has increased.

　　For pickup trucks that undertake multiple tasks such as production and travel, fuel saving is very important. In recent years, fuel-saving configuration has gradually appeared on domestic pickup trucks, especially the increase of high-end pickup products, which has gradually popularized the ECO economic model. After the ECO mode is turned on, the vehicle will run in the economic mode, the fuel injection quantity will be controlled by the vehicle computer, and the shift logic will be controlled by the gearbox control module, so that the vehicle can run in the most economical mode to achieve the purpose of fuel saving. At present, ECO economic model is becoming more and more common in high-end automatic pickup products.

　　Changchengpao

　　As a representative work of domestic pickup trucks, 8AT models of Great Wall Gun have fuel-saving economic models to choose from. Among them, the Great Wall commercial gun is equipped with three driving modes: economy, standard and sport, the passenger gun has four driving modes: standard, economy, 4L and sport, and the off-road gun is equipped with seven all-terrain driving control modes (standard, economy, sport, snow, mud, sand and 4L). In the economic mode, the acceleration of the Great Wall Gun is relatively smooth, the throttle and brakes are also very comfortable, and the steering wheel is relatively light, which is suitable for driving on flat sections of the city.

　　SAIC Datong T70/T90

　　In the domestic pickup truck market, SAIC Chase was the first pickup truck product to launch the ECO ECOnomic model. As early as the T60 was launched in 2017, SAIC Datong simultaneously launched the concept of "three-mode driving", namely eco mode, POWER mode and NORMAL mode. On T70 and T90, which went on the market later, the three-mode driving mode was still continued. When driving on expressways and urban roads, the ECO mode can be started, and the fuel saving effect can be achieved.

　　Jiangling domain tiger 9

　　As the highest-end product of Jiangling pickup truck, Domain Tiger 9 is not inferior in technology configuration, and it is also the first diesel pickup truck in China to realize 8-speed automatic transmission. Domain Tiger 9 uses the BOG Warner TOD two-speed intelligent four-wheel drive system, which can realize eight different driving modes, such as mud, sand, snow, rock, 4L, 4H, sports mode and economic mode. The car sits comfortably and has a wide field of vision when driving. After the economic mode is turned on, the steering wheel is soft, and its strength and quality can be comparable to those of SUVs at the same price.

　　Zhengzhou Nissan Ruiqi 6

　　Ruiqi 6 is one of the core products of Zhengzhou Nissan, and it has always had strong competitiveness in the domestic pickup truck market. Ruiqi 6 automatic transmission has four driving modes: standard, ECO (economy), SPORT (sports) and SNOW (snow), and there are control buttons under the air conditioning panel. After the economy mode is started, the vehicle gearbox upshifts actively, and will maintain a lower speed to obtain better fuel economy.

　　China heavy duty truck VGV VX7

　　In February this year, China Heavy Duty Truck VGV, a new force car company in the domestic pickup truck industry, launched its first pickup VX7, which is unique because of its load-bearing body structure, rich safety and intelligent configuration. VX7 pickup truck adopts 8AT gearbox, which can shift smoothly. The electronic knob shift design can realize the freedom of switching between economic, sports, snow and other multi-scene modes. For this pickup truck which is mainly used in cities, the fuel-saving economic model is very useful.

　　General Futian

　　General Futian pickup truck is a brand-new pickup truck model of Foton Motor, and the diesel 8AT combination is also in the forefront of the market. General G9 provides ECO mode and SPORT mode. Users can switch between them by pressing buttons, and choose energy-saving or sports driving mode according to their needs, so as to obtain corresponding dynamic response. In ECO mode, the whole car looks lazy, and it is very friendly to the fuel economy of the vehicle at low speed.

　　Chang ‘an Kaicheng F70

　　Chang ‘an Kaicheng F70 is a representative product of a new brand and model of pickup truck in China. The performance of its automatic transmission model has impressed users deeply. Like many mid-to high-end pickup trucks, Chang ‘an Kaicheng F70 automatic transmission model also has a "three-mode driving mode", namely, standard (NORMAL), ECOnomy (eco) and SPORT. Under the economic mode, Chang ‘an Kaicheng F70 appears to be much more obedient, and fuel saving is its core logic, and on this basis, it achieves the balance between performance and fuel consumption.

　　With the rise of oil price, car owners pay more and more attention to fuel-saving driving skills, and the electronic configuration with fuel-saving function has also received more attention, and the ECO economic model has become popular at this time. After the ECO mode is turned on, the fuel consumption can be reduced to a certain extent, but the driving pleasure is indeed discounted accordingly. If card friends don’t want to sacrifice driving pleasure at ordinary times, they can only turn it on when driving on urban roads to realize intelligent fuel saving.

How much do you know about the background story of ＂Hunting in the Air＂？

1905 movie network news 2017 is a big year for audiences who love war movies. The appearance of the movie has boosted the box office of China mainland to an unprecedented height, and also let everyone see the potential of domestic main melody films. Later, it was shown in the mainland, showing the individual’s experience in the war, and the smoke of war decades ago reappeared on the screen. In contrast, aiming at the eleventh gear is a sword on the side, which shows the People’s Air Force under the background of the new international situation and the information age for the first time, and also shows the equipment development and actual combat capability of the People’s Air Force in the past five years.

As the first work directed and performed by Jerry Lee, Hunting in the Sky tells the story of the squadron of "Overlord Sirius" which gathers the elite of the air force, and is ordered to attack bravely in the face of the crisis when terrorists from neighboring countries control the missile well and take China citizens hostage. Among them, the emotional line between Jerry Lee and Fan Bingbing runs through from beginning to end, and transnational joint anti-terrorism and assistance to China citizens are also displayed in great length.

The main performance of "Hunting in the Air" is air force pilots, and air combat is the biggest attraction of this film. The main aircraft types of the Air Force, such as J -20, J -11B, J -10C, Yun -20, Air Police 500, Zhi -8, Zhi -9, etc., appeared in a concentrated manner, among which J-20 appeared in a fighting posture for the first time, and J -10C and Mirage 2000 confronted each other in complex terrain, and all kinds of difficult tactical actions were very enjoyable.

For war-themed works, if you don’t know much about the background knowledge of the film, the viewing effect will be greatly reduced, and the little knowledge behind the film "Hunting in the Air" is actually more interesting.

Military uniform: 17-style flight suit, 07-style military uniform, camouflage uniform.

Whether in the film or at the press conference, Li Chen is wearing a new flight suit that has not yet been installed. This gray-green one-piece flight suit looks simple and beautiful, and its subordinate troops are marked in an eye-catching position on the chest, which is obviously different from the current Type 02 flight suit in terms of color and style.

In a scene of parachute training in desert area, Jerry Lee, wearing a 17-style flight suit, was able to move freely after landing. He used his running track to write down the coordinate orientation of "South Mountain South" in the navigation system, which showed that this one-piece flight suit was light and convenient for pilots to move in a narrow cockpit.

At the same time, there is also a winter flying leather coat that is different from the current equipment, and there is an obvious hook and loop combination of rank and name on the chest of the leather coat. There is also a pocket with zipper above the left arm for convenient storage. This flying leather coat is more like a symbol of the membership of Batian Wolf Squadron in the film, which belongs to the fiction in the film.

The 07 navy uniform was briefly introduced in Wolf Warriors 2, and the 07 air force uniform was also shown in more space in Hunting in the Air. According to the rank configuration, the role played by Wang Xueyin, an old opera player, is the highest. When entering the command center, Wang Xueyin appeared in a uniform coat. This coat is designed with hidden buttons and a belt at the waist, which is simple and generous. Comparing the uniforms of Wu Xiubo, Fan Bingbing and others, it will be found that Wang Xueyin’s big-brimmed hat is equipped with golden ribbons and brim flowers, while the ribbons of field officers and commandant officers are light blue.

As the representative of the female soldier image in the film, Fan Bingbing appeared in the camera with the unique rolled-off hat of female soldiers, and sat under the stage with the captain’s epaulettes to listen to the speech of the senior colonel played by Wu Xiubo.

In camouflage clothing, there are three kinds of undistributed equipment in "Hunting in the Sky": desert camouflage, blurred edge camouflage and snow camouflage. Among them, snow camouflage adds light gray to the white background, which is convenient to blend in with the surrounding environment.

According to the different environment, the airborne soldiers use the camouflage with blurred edges in the film, which can play an excellent camouflage effect in the dark.

Noun explanation: Barents sea scalpel with gold helmet

When recruiting excellent pilots to join the "Sirius" squadron, Wang Qianyuan repeatedly emphasized the golden helmet pilots, and the so-called golden helmet was actually a flying skill competition award set up by the China Air Force. As an annual competition, the pilots who compete in air-to-air competitions every year will get the physical reward of the golden helmet, which symbolizes the highest honor of the pilots and is also an affirmation of their ability.

When Wang Qianyuan was teaching students the history of war, he used Jerry Lee to intercept enemy fighters and compared it with the scalpel incident in Barents Sea. As the most famous Soviet air collision case during the Cold War, the Barents Sea scalpel incident has been mentioned many times. In 1987, the Norwegian Air Force’s P-3B anti-submarine patrol aircraft encountered a Soviet Air Force Su -27 fighter and was damaged by the other side’s vertical tail. According to the disclosure afterwards, the aerial contest consisted of three rounds and lasted for 17 minutes.

Main aircraft types: J -20, J -11B, J -10C, Yun -20, Air Police -500, Mirage 2000, Zhi -8 and Zhi -9.

"Hunting in the Air" is also a concentrated display of China Air Force equipment. The appearances of J -20, J -11B, J -10C, Yun -20, Air Police 500, Zhi -8 and Zhi -9 are dizzying, among which Yun-20 and J-20 appeared in front of the audience for the first time in a fighting posture. On the day before the film was released, a spokesman for China’s Ministry of National Defense said at a regular press conference of the Ministry of National Defense that the J -20 had been equipped with troops, which showed that this fighter had been finalized and entered the stage of small-scale production.

J -11B is the fighter plane that entered Mabu for the first time to perform its mission, with Wang Qianyuan as the leader and Jerry Lee as the wingman. After encountering the Sam -6 anti-aircraft missile controlled by terrorists, he made a wonderful escape. Finally, Jerry Lee accelerated to climb up after receiving the instructions, and Wang Qianyuan’s landline was damaged by the missile, and he himself was seriously injured in the eye.

A set of "combination boxing" appeared when the fighter plane was damaged and attacked Mabu again. Rainbow -5, a new UAV developed in China, cooperated with J -10C and Air Police -500 early warning aircraft mounted with Eagle Strike 91 anti-radar missiles, and Yun -20, which can perform long-distance air transportation tasks, and finally eliminated the terrorists entrenched in Mabu.

In the performance of foreign fighters, Mirage 2000 and F-15 appeared, among which the confrontation between J -10C and Mirage 2000 machine gun developed by France became the biggest highlight, and the picture of the confrontation between the two fighters in the valley was unforgettable.

In the film, Fan Bingbing plays a pilot who mainly flies a helicopter to perform a search and rescue mission. In the first mission to rescue people trapped by mudslides, Zhi -9 appeared, and the last mission was to drive Zhi -8.

Zhi -8 is a multi-purpose helicopter with many improved models, which was used to carry China citizens in Mabu in "Hunting in the Air". It can be clearly seen that the excellent transport capacity of Zhi -8 makes the overseas evacuation of overseas Chinese by the Air Force go smoothly, and it is also relatively smooth to travel through the complex terrain in mountainous areas. After terrorists from Mabu took the Mirage 2000 to aim at Zhi -8 on the way home, Jerry Lee made the decision of plane collision without ammunition.

Zhi -9 is a picture when the film begins to introduce Fan Bingbing who joined the Batianlang team. When the mudslide rushed to the primary school, Zhi -9 hovered over the target building and rescued the victims through ropes at the last minute.

Other equipment: reconnaissance robot, Bobcat ATV, Land Shield 2000 air defense system.

In the film, there are also brief pictures of reconnaissance robots, Bobcat ATVs, Land Shield 2000 air defense systems and other equipment, among which the domestic Bobcat ATVs with compact design and excellent handling performance performed well. This kind of car is used by airborne troops in the film, and it can gallop after carrying six passengers, which plays an auxiliary role in eliminating terrorists.

Land Shield 2000 air defense system appears in the film, which is used for terminal defense of the airport and can effectively intercept low-altitude targets such as air-to-ground missiles, cruise missiles and helicopters.

"Hunting in the Air" shows a lot of air force equipment for the first time, which is unforgettable. It is also a film that once again shows the image of China’s contemporary soldiers on the screen after the appearance of "Wolf Warriors 2", which triggered the topic. It has played an important role in establishing the image of contemporary China soldiers, enhancing people’s patriotic enthusiasm, and letting more and more audiences see the potential of China’s main melody films.
