Tomorrow is 515, the anniversary of the starting point, and the day with the most benefits. www.biquge.info In addition to the gift bag and schoolbag, this time the 515 red envelope must be turned over, how can the red envelope not rob the reason, set the alarm clock ang~

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

The deceased's name is Zhang Ming, 28 years old, non-Kyoto, college graduate, and has worked in various occupations; The husband of the deceased, Chu Xinjian, was a 42-year-old vice president of a listed company, who had just divorced his ex-wife shortly before marrying Zhang Ming and had a 12-year-old daughter.

According to the information collected by the police, this is a standard story of the top three, Zhang Ming and Chu Xinjian met because of a rear-end accident, and finally the two got acquainted with each other and fell in love until they got married.

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

No wonder the police feel that Chu Xinjian has no suspicions, it is conceivable that Chu Xinjian is not young, and as a company executive, he will definitely consider the problem quite comprehensively and thoughtfully, and will not make a decision easily.

Since he paid a huge price to abandon his original partner and marry Zhang Ming, it is unlikely that in just one year, his relationship will change dramatically, and it will be so huge that he wants to kill someone. So from this point of view, Chu Xinjian does not seem to have a motive to kill. I don't know how the police analyzed the case and listed Chu Xinjian as the first suspect.

Mo Hui roughly prepared, and was ready to start stealing Chu Xinjian's private information, he decided to use WeChat as a breakthrough to get the password of WeChat first.

Instead of using a standard HTTP/HTTPS session, WeChat has implemented a customized communication protocol on its own, 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 is also a problem with the way WeChat reads the debugging settings, it can be equipped to send the log to a remote server, the log contains the user password in MD5 format, which is easy to crack, WeChat's local database uses sqlite's encryption extension sqlcipher encryption, and the key generation algorithm truncates the password into 7 16 decimal characters, and brute force cracking is not difficult.

And Mo Hui's choice is to crack it brute-forced, because he can't intercept Chu Xinjian's communication packets, so he can only crack the password remotely.

When you send a registration request through the script automation, the server will automatically return the database comparison results, such as whether the username has been used.

There is a slight difference between the username that has been used and the username that has been used but the password is incorrect, and the packets returned are different. Mohui grabs the return packet to determine whether the password is correct.

In fact, there is no limit to the number of verifications to register, if he brute-force the password on the login page, the account will be suspended after a few trial and error, so Chu Xinjian will definitely notice the abnormality.

If you want to avoid abnormal data being detected by the server, you just need to change some broilers and forge a large number of IPs to make registration attempts at the same time.

A person's password choice rarely appears out of thin air, and most of them have various correlations with their own information, so on the basis of obtaining Chu Xinjian's relevant information, it is much less difficult to break it. Mo Hui only tried for more than an hour, and he got Chu Xinjian's WeChat password.

Mo Hui is not in a hurry to move on to the next step, because he will operate accordingly, if there will be a reaction on Chu Xinjian's WeChat, as long as Chu Xinjian's WeChat has been hanging, it is easy to have problems.

So Mo Hui deliberately waited for more than 4 o'clock in the middle of the night before logging in to Chu Xinjian's WeChat with a virtual mobile phone, and Mo Hui didn't move anything when he entered WeChat, but just used WeChat to follow an official account.

This official account is actually a Trojan horse's vest, when Chu Xinjian logs in to WeChat, the Trojan horse will quietly take root in his mobile phone, because it is associated with WeChat, so this Trojan can easily avoid the supervision of mobile phone security software.

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

When the Trojan invades, Mo Hui is equivalent to setting up a small spy in the opponent's mobile phone and PC, which can be remotely controlled through the Trojan if necessary.

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

Two days later, Mo Hui checked the information sent back by the Trojan and found that Chu Xinjian didn't seem to have the habit of using the PC version of WeChat, and he had only used that mobile phone all along.

Mo Hui began to use the Trojan horse to collect information on the mobile phone during the time when the phone was sleeping, first of all, WeChat's chat history is a must, Mo Hui is like a mouse stealing eggs, and the chat history has been moved back many times and little by little.

Not only is there a chat record in the mobile phone, but Mo Hui also found Didi, it seems that Chu Xinjian's divorce still has a great impact on his daily life. In addition, there is Alipay, a credit card official account, bank card information, his address book, his photo library, and a Weibo account that he often logs in~~~~

After conquering the mobile phone, it was very easy later, and in the following week, Mo Hui successfully planted a Trojan horse in Chu Xinjian's two notebooks, an iPad, and another mobile phone, and all the information on it, as well as Chu Xinjian's commonly used account passwords.

Wang Xiaoqiang was very excited to devote himself to the examination of this information, and the whole process of Chu Xinjian and Zhang Ming's acquaintance gradually leaked out.

Zhang Ming's relevant information was obtained through the landlord Li Gang, and the two sides compared and verified, and did not find too many abnormalities, Chu Xinjian and Zhang Ming did not seem to have any major conflicts for a period of time before the deceased's death.

This situation made Wang Xiaoqiang very frustrated, he felt that it shouldn't be like this, how could it be that there were no signs of it.

Mo Hui had no choice but to comfort him, "If you think about it differently, Zhang Ming and Chu Xinjian will inevitably face each other day and night as husband and wife, and they don't have to communicate through electronic devices at all about many things, just go home from work and talk about it in bed." ”

"It's also right~~~, so what should I do? Zhang Ming is dead, who knows what happened to the two of them locked up in a hut. ”

"I think that Zhang Ming's social relationship is relatively simple, you can take her as the center of the circle, check her relation, and then see which of them have contact with Chu Xinjian, and search for Chu Xinjian's information accordingly to see if you can find something in the middle."

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