[Latest Broadcast] Tomorrow is 515, the starting point anniversary, the most benefits day. In addition to gift bags and school bags, this time the "515 red envelopes are flirted with" must be seen. There is no reason to not grab red envelopes. Set an alarm clock~

Mo Hui hasn't started working yet, Wang Xiaoqiang has already asked the landlord for information about the case.

The deceased is Zhang Ming, 28 years old, not from Kyoto, graduated from college, and has worked in various occupations. The deceased's husband Chu Xinjian, is the vice president of a listed company, 42 years old. He just divorced his ex-wife not long before marrying Zhang Ming and had a 12-year-old daughter.

Information collected from the police showed that this was a standard story of a mistress. Zhang Ming and Chu Xinjian met because of a rear-end accident. In the end, the two met each other and fell in love until they got married.

Chu Xinjian paid a huge price to marry Zhang Ming. In order to divorce his ex-wife, he almost left the house in vain, which led to him renting a house with Zhang Ming after marriage, and he didn't even have a car to carry on.

No wonder the police think that Chu Xinjian has no doubts. You can imagine that Chu Xinjian is not young anymore, and as a company executive, he will definitely consider issues very comprehensively and thoughtfully and will not make a decision easily.

Since he paid a huge price to abandon his original wife and marry Zhang Ming, it is unlikely that his relationship will change tremendously in just one year, and it will be so huge that he wants to kill people. So from this perspective, Chu Xinjian seems to have no motive for murder. He just doesn't know how the police conducted the case analysis and ranked Chu Xinjian as the first suspect.

Mo Hui made a rough preparation and was about to start stealing Chu Xinjian's private information. He decided to use WeChat as a breakthrough to get the WeChat password first.

Instead of using standard HTTP/HTTPS sessions, WeChat implements a customized communication protocol itself, mainly transmitting information through TCP port 8080. This data transmission mode determines that WeChat's data transmission information can be quickly intercepted and decrypted.

There are also problems with the way of reading and debugging settings of WeChat. It can be equipped to send logs to remote servers. The log contains user passwords in MD5 format, which is easy to crack. WeChat's local database uses SQLite's encryption extension SQLCipher encryption. The key generation algorithm cuts the password into 7 hexadecimal characters, so brute force cracking is not difficult.

The way Mo Hui chose was to crack brute force, because he could not intercept Chu Xinjian's communication data packet, so he could only crack the password remotely.

Don’t click back and click on a few scripts you wrote yourself and start logging into the WeChat registration page. When automatically sending registration requests through the script, the server will automatically return the database comparison results, such as whether the username has been used.

There is a slight difference between this. The username has been used, and the username has been used but the password is incorrect. The returned data packet is different. Don’t reply to determine whether the password is correct by crawling the returned data packet.

Registration actually has no limit on the number of verifications. If he brute-forced the password on the login page, the account will be blocked after several trial and error, so Chu Xinjian will definitely notice the abnormality.

If you break through the registration page, there is no problem. If you want to avoid abnormal data being detected by the server, just change more broilers and fake a large number of IPs to register at the same time.

In fact, a person's password choice rarely appears out of thin air, and most of them have various correlations with their own information. Therefore, based on the information related to Chu Xinjian, the difficulty of breaking is much smaller. Mo Hui only tried for more than an hour and got Chu Xinjian's WeChat password.

Mo Hui was not in a hurry to go to the next step because he performed the corresponding operation here. If there was a reaction on Chu Xinjian's WeChat, as long as Chu Xinjian's WeChat was always on, problems would be prone to occur.

So Mo Hui waited specifically for about 4 o'clock in the middle of the night before logging in to Chu Xinjian's WeChat with a virtual phone. Mo Hui moved nothing when he entered WeChat, but just followed a public account with WeChat.

This official account is actually a Trojan horse. When Chu Xinjian logs into WeChat, the Trojan will quietly take root in his mobile phone. Because it is related to WeChat, this Trojan horse can easily avoid the supervision of mobile phone security software.

And there is an additional benefit. If Chu Xinjian is used to using PC version of WeChat, then which machine he uses will be invaded by this Trojan horse.

When the Trojan invades, Mo Hui is equivalent to setting up a small spy on the other party’s mobile phone and PC. If necessary, you can remotely control it through the Trojan.

After following the official account, Mo Hui threw it aside and went to sleep.

Two days later, Mo Hui checked the Trojan and found that Chu Xinjian didn't seem to have the habit of using PC version of WeChat, and he has always used only that mobile phone.

Mo Hui started to use Trojan horses to collect information on the phone during the time of his mobile phone hibernation. First of all, WeChat chat records are a must. Mo Hui is like a mouse stealing eggs. The chat records are moved back one by one in multiple times.

Not only did there be chat records on your phone, Mo Hui also found Didi. It seems that Chu Xinjian's divorce has had a significant impact on his daily life. In addition, there is also Alipay, a credit card official account, bank card information, his address book, his photo library, and a Weibo account that he often logs in to~~~~

After conquering the mobile phone, it was easy to come later. In the following week, Mo Hui successfully planted Trojans in two laptops, one iPad, and another mobile phone that Chu Xinjian built, and guided all the information on it, as well as Chu Xinjian's commonly used account and password.

Wang Xiaoqiang was extremely excited to investigate this information, and the whole process of Chu Xinjian and Zhang Ming getting to know each other gradually leaked out.

Zhang Ming’s relevant information was obtained through the landlord Li Gang. The two parties conducted comparative verification and did not find too many abnormalities. Chu Xinjian and Zhang Ming did not seem to have any major conflicts before the deceased’s death.

This situation made Wang Xiaoqiang very frustrated. He felt that this shouldn't be the case. How could any signs not be revealed?

Mo Hui had to comfort him, "If you think about it, think about it, Zhang Ming and Chu Xinjian must be together day and night, and they don't have to communicate with many things through electronic devices at all. Just go home from get off work and say it in bed."

"It's right~~~, what should I do? Zhang Ming is dead, who knows what happened when the two of them are locked in a small house."

"I think Zhang Ming's social relationship is relatively simple. You can treat her as the center of the circle and check her relationship, and then see which of them has contacted Chu Xinjian. The corresponding search for Chu Xinjian's information to see if you can find something in the middle."

This is actually just a simple way to denoise, because as a company executive, Chu Xinjian has very complex social relations and many contacts every day. This creates a lot of useless information clutter, which invisibly increases the workload. If you want to find information related to this case, the best way is to use correlation to denoise!
