Chen Xu uploaded the extracted information to the self-made intelligent crawler software, and then hung it on the major search engines and APP platforms to start retrieval.

There are a lot of interesting things that crawlers can do.

For example, climb the recruitment information and real estate information of major cities;

Crawl major e-commerce websites for product sales information and user evaluation;

Climb the user consumption and evaluation of various stores of catering websites such as Dianping and Meituan;

As long as Yanyu Xiaoxiao has left footprints on these websites and used the same registration information and user nicknames, it can be found.

That's how those peels often come about.

The mouth is cool for a while, and the skin is ruined for life.

Many keyboard warriors hiding behind the computer think they are safe, but they don't know that they are actually running naked in the emperor's new clothes.

After hanging up the crawler software, Chen Xu went to school.

After the second class in the morning, Zhu Cheng came to him and told him that he would go to Switzerland tomorrow.

Chen Xu is naturally envious, jealous and hateful.

"How's that going on with that?"

"What's the matter?"

"Weiye data security consultant, didn't I tell you before. ”

The two of them were standing by the corridor window of the teaching building and chatting, the winter sun shining through the glass on their bodies, warm and comfortable.

Chen Xu leaned against the glass and said, "The problem is that I'm busy now, and I don't have time to be a safety consultant for Rausch."

Zhu Chengyun smiled and said: "You don't understand, data security consultant is a title, not responsible for specific affairs, and you don't have to clock in to Weiye on time, to put it simply, Weiye spends money to buy a psychological comfort, tell yourself, if there is a problem in the IDC computer room in the future, everything will be in charge of you, the data god!"

After a pause, Zhu Carrier said: "Of course, if there is a problem with Weiye data one day, the recovery fee will still be calculated separately, understand." ”

"So, that'......"

"You said salary, right?" Zhu Cheng smiled and said, "The salary is 30,000 a month, if you want to agree, it will be calculated from today." How's that, do you want to do it?"

"Nonsense, of course I did. Chen Xu immediately smiled when he heard this. You don't have to do anything, you get 300,000 yuan a year, and you don't want it if your brain is in water.

In two days, Weiye Group will mail you a letter of appointment, you should pay attention to check it. ”

"Well, got it. ”

"Let's go~" Zhu Carrier waved his hand, turned around, and showed a relaxed look on his face.

Last time, Chen Xu repaired the data for Weiye, and only collected 800,000 yuan, and he was ashamed of this matter.

At that time, he knew that even if Chen Xu asked for 8 million, Weiye Group could only pinch his nose and admit it, but he didn't remind him out of selfishness.

Because if Chen Xu really asked for 8 million, then this matter is a commercial behavior, as a middleman, he can be said to have no credit at all, maybe after talking about Yongsi, he will think that Chen Xu took advantage of the fire to rob, so he was angry with him.

It's not out of the question.

The human heart is complicated, and he can't take that risk.

So I can only sacrifice Chen Xu's interests.

It is precisely because of this that he tried his best to promote Chen Xu's title of security advisor, which can be regarded as making up for part of his losses. Otherwise, this matter is likely to be over.

In short, it's a win-win situation.

……

When Chen Xu returned to Zizhu Garden in the evening, the crawler software had crawled back hundreds of gigabytes of information from the network.

With such a huge amount of information, it is not necessary to change the general program ape to "noise reduction" processing, and there is no need to straighten out the clue in three or five days.

But Chen Xu is different, Xiaobai personally went out, and the noise reduction treatment or something is a piece of cake.

Hundreds of gigabytes of data have become more than 10 gigabytes in the blink of an eye.

Then it continued to shrink to less than a G.

The rest need to be screened one by one.

As I said before, in these data, there are not only user evaluation information of major e-commerce companies, but also consumption information and evaluation of catering websites, as well as comments on Weibo, Douyin, and Station B.

It didn't take much effort, Chen Xu found information in the refined database that was more consistent with the information left by Yanyu Xiaoxiao in Weixin, and according to this information, he tracked down Yanyu Xiaoxiao's accounts on Station B, Douyin, and Weibo.

Then you get the following information.

Name: Xie Yuxiao/Wang Hong.

Customary nickname: Yanyu Xiaoxiao / Yanyu Xiaoxiang.

Date of birth: May 13, 1997.

Nationality: A native of Xingcheng, Hunan Province.

ID number: xxxxxxxxxxxxxxx.

Mobile phone number: 1377**********.

Family situation: My parents divorced at an early age and I have a brother-in-law.

Hobbies: singing, dancing, piano and chess, calligraphy and painting.

Personal information is basically cleaned up.

In the social APP, the attention is paid to some travel bar owners.

And she wrote in her personal note: I am twenty-one years old on this day, which is the golden time of my life, and I want to earn 500 million before the age of 25, and travel around the world and wander the world from now on.

When ordinary people see this declaration, they laugh at most, and say in their hearts that people who have not been beaten by society are always so naïve and ridiculous when they speak.

But after learning some information about this girl, Chen Xu couldn't laugh at all, and even felt a little terrifying, this is definitely a ruthless stubble.

As for how ruthless it is, it needs to be investigated.

Using this known information, Chen Xu began to crack Yanyu Xiaoxiao's social account.

With the above information, plus some private information obtained earlier, cracking the password becomes a breeze.

Through brute-force cracking, he got the account passwords of Weixin and Douban, and then the passwords of all Xie Yuxiao's social accounts were exposed in front of Chen Xu.

At this point, it's basically done, and all that's left is to do your homework around this woman and see what kind of person she really is?

The crawler software continues to hang, but it is no longer aimed at the massive data of search engines and major apps, but crawls the information in all of Xie Yuxiao's online accounts, such as social travel: Didi, AutoNavi, Tencent Map, Baidu Map;

Shopping payment: Alipay, Taobao, Meituan;

Skin care and health: true self, beauty practice, peppermint fitness;

Photography: BeautyCam, faceu;

Entertainment software: iQiyi, Tencent, Weibo, Youku, Douyin, Kugou, QQ Music, NetEase Cloud......

At night, Chen Xu concocted the same method and implanted a Trojan horse in Xie Yuxiao's Weixin account.

In addition to Weixin, he also planted a Trojan in her QQ background folder.

This Trojan mainly monitors the network status of the device.

To put it simply, at home or at work, there is generally WiFi, and then because of the wall blocking, or going out, the WiFi is disconnected.

As long as the monitoring frequency is frequent enough, then combined with certain logical reasoning, it is completely possible to infer a person's work and rest time, including the state at home. For example, squatting in the pit to play with mobile phones, because of the poor signal, many people will get used to temporarily turning off the WiFi.

The implementation method is also very simple, that is, run the emulator of Android and iOS, and then use the key wizard to simulate the network status screenshot, and use curl to post to the server, and the server will save the time and screenshot of each sending.

Because it is a screenshot with the program, as long as the network status is the same, then the screenshot is the same, so that the server will only save 2~3 pictures. Then I did OCR (text recognition) manually, and I still noticed that there were only 2~3 pictures, so the workload was very small.

Under the combination of the two, it can be said that now Xie Yuxiao is completely under his 360-degree monitoring without dead ends.

When to get up, eat, go to the toilet, go out, where to go, who you have called and sent messages to, who you have been in contact with, go home, shop, sleep, etc., will be intuitively presented in front of Chen Xu through data information.

After doing these well, Chen Xu didn't care anymore.

……

……

On Friday, December 7th, it snowed heavily.

Shao Hong came to BJ District in the morning.

Version 1.1 of Xiaobai Dialect Translator has already completed the packaging test, but Chen Xu has not contacted Shao Hongcai.

Seriously, if the other party helps him promote on the Internet, take some advertising or something, he is quite happy, the total number of downloads of several major application platforms has been tens of thousands, and there are small advertisers to contact him to advertise a few days ago.

But now he is not optimistic about making it into a translation machine to sell.

Now that the economy is sluggish and the investment risk is high, Shao Hongcai is not a professional, and it is easy to lose money.

The most important thing is that the dialect is not a foreign language translation, and there is no market prospect, so he is too lazy to toss.

It's just that Shao Hong didn't insist, he had been grinding hard and soaking, so he went with him, and he didn't want him to invest a penny anyway.

In a coffee house near the university town, after the two of them discussed, Chen Xu signed an agency agreement to Shao Hongcai on the spot.

Shao Hongcai was overjoyed, took the agency agreement and looked at it again and again, and finally solemnly put it into his backpack.

"Then I'll go first, and if there's any problem with the software, just call me. Chen Xu got up and arrived.

"Okay, you go slowly. ”
