365 Difficult Ways To Live

After being stiff for a few seconds, Muyu returned to normal and accepted the reality.

Chu Yu was still in a daze, as if he hadn't recovered, but also seemed to be thinking, staring at the screen and concentrating.

Muyu put his hand on her shoulder, "Boss, it's okay, maybe it's like what Xiao Bang said. After finding out the truth, Xiao Huaihua was given a heavier sentence. It's a blessing in disguise. Maybe she doesn't want others to know her past."

Chu Yu propped his hand on the computer desk, pointed at the screen, "No, I think we can dig deeper."

"An old man in his 70s?"

The information shows that the owner of the ID card is Jiang Jianzhou, 70 years old, and lives in Weini Community, Linquan North Road.

Chu Yu nodded, although he expressed his affirmation, but his expression was confused: "I think the elderly are also suspected."

"Chu Chu, if you are 50 years old, it is still possible, but if you are 80 years old, you may not even know how to use a smartphone. The possibility of helping Xiao Huaihua is too small. Even if she wants to find an accomplice, why can't she think about it? Looking for an old man who may not be able to read clearly?"

"So you think Comrade Jiang Jianzhou is completely unaware?"

Muyu looked at the transaction records given by the bank, and said, "It should be. In fact, I think the chance of finding X in this way is relatively small. Although Xiaohuaihua has a bank card, a payment account, and an ID card and phone numbers, but these are not necessarily X’s own, or she may have stolen other people’s information for her own use.”

Chu Yu took the bank records in her hand and scanned the time with his eyes, "This card has been in use for 13 years and has been used in Wangjiang City, but it started two months ago, and the transaction places are spread across two provinces and cities. Luoyu City and Jinling City are also in line with Xiaohuaihua's trajectory, so it is certain that she used it. This shows that this card was first held by Jiang Jianzhou and later transferred to Xiaohuaihua. If the old man did not take the initiative to give the card to She, then he might have lost his card and was picked up by Xiao Huaihua, but if that's the case, why didn't he report the loss?"

"His card is still a magnetic stripe card, and has not been replaced with a chip. The principle of the magnetic stripe card is like a magnetic tape. It has low technology content and has no encryption key. It can be copied. Maybe the old man's card has been copied, but he didn't notice it. "

"But after copying the bank card, the password is still required?"

The corners of Muyu's mouth curled slightly, showing the proficiency of the "undebuted hacker": "There are many ways to obtain passwords, and it is relatively simple for the elderly to set passwords, such as birthdays, continuous numbers, and I think that since Xiaohuaihua has the ability to Copy the bank card of the other party, and you must be able to get the password."

Chu Yu once again expressed doubts: "But the use of the payment platform requires a mobile phone verification code. Whether it is a bank card or Alipay, it is bound to the old man's mobile phone number. If the old man didn't provide it on his own initiative, how did she know?"

"This can be achieved. If the old man accidentally clicks on the link she sent, a Trojan horse program is installed in the phone, and the corresponding permissions are enabled, then she can know all the verification codes."

After Muyu finished speaking, he turned his attention to the computer page of "witness the miracle" again, "Maybe Xiao Huaihua is eyeing him because he is an old man who knows nothing about the Internet, doesn't know how to check consumption records, and is unlikely to find that his ID card is bound. Suspicious accounts so she can get away with it.”

Chu Yu frowned slightly, thinking about what she said, and after a long silence, he said to Muyu, "Call Xiao Bang and Da Tuo over."

Seeing her like this, Mu Yu knew that she had something to discuss, so she didn't say much, and immediately contacted the other two.

Song Qingyang and Fang Datuo only knew that Chu Yu had achieved results in the bank, but they were busy with their own business, so they didn't gather in the technical department office. When they heard the call, they put down their work and rushed over.

As soon as Song Qingyang entered the door, she inquired about the result. Muyu showed her Grandpa Jiang's information, and she pouted, "Who are we looking for? The mysterious person who sent text messages?"

Fang Datuo sat down and shaved his hair, "I have thought about countless possibilities, men, women, children, teenagers, but I just never thought of being an old man. Do you suspect that he is not X?"

Mu Yu looked at Chu Yu and didn't speak for a while.

Chu Yu stared at the center of the table, blinking his eyelashes occasionally, and looked solemnly, "Yes, we have very little information about X now, just a text message, if I have to make a psychological portrait of X, I think he It should be a teenager, aged 23 to [-], has a criminal history, participated in a crime directly or indirectly, but has not been arrested, introverted, timid, not talkative, simple interpersonal relationship, innocent on the surface, but familiar with anti-investigation methods , know how to evade police pursuit."

The three clerks looked at her and were stunned, "Just one text message, five numbers, you put out so many?"

Chu Yu didn't answer, her eyes were a bit mysterious - she had a guess about Xiao Huaihua's experience in the past four years, so she speculated on X's characteristics based on her experience.

Fang Datuo: "In this way, Jiang Jianzhou can be ruled out?"

"Muyu and I discussed it just now, guessing that he might not know about it, but the information was stolen and used by Xiaohuaihua."

Muyu: "Yes, although Xiao Huaihua used his bank card and payment account to bind his mobile phone number and ID card, but these can all be achieved through illegal means."

Chu Yu nodded, and continued her words: "I first thought that it was X who provided financial support to Xiao Huaihua, because her situation is different from ordinary financial fraud, and she needs a stable and reliable source of income, and to do this One point is to have a real ID card as a guarantee. First, she cannot use her own ID card, and she does not have an ID card; Financial institutions or the Public Security Bureau responded that once she was discovered, her financial resources would be cut off immediately, and there was a risk of being arrested by the police;

Third, I have thought that she might look for loopholes in banks and payment platforms, but like payment platforms, the safety factor is extremely high, and the programmers are top-notch in China. So far, no accidents have occurred. It is necessary to hack in and tamper with the data. almost impossible.As soon as Xiao Huaihua took action, she committed crimes for a long time, and the time span was several months or even longer. , It is necessary to ensure that one's own source of income is very stable and will never be discovered and tracked. "

Muyu understood what she meant, "So you guess, her source of income is a real person, and her ID card, payment account number, and phone number are all real. Even if you check it, you can't find any problems?"

Chu Yu nodded, "Combined with that text message, I suspect that the source of income is X."

"But now the source of income proves to be an old man. You just speculated about X's characteristics, and he is a teenager. Does it mean that we have found the wrong person? Xiao Huaihua didn't ask X to help her?"

Chu Yu narrowed his eyes slightly, "Just now Muyu said that Xiao Huaihua may have copied the old man's bank card, because the card is a magnetic stripe card. Since the chip card was issued, the bank has been urging users to change the card. Like this old man, although Now the magnetic stripe bank card can still be used, but the bank will send him a text message. Every time he goes to the bank, the teller may advise him to change the card. If one day he updates the bank card, the card of Xiaohuaihua Wouldn't it just be scrapped?"

"So you suspect that Jiang Jianzhou is also suspicious?"

"It seems that we can't get rid of the suspicion now. It's safer for us to check it ourselves."

The four discussed it and started to take action, but this time my heart was heavy and I felt like I was going to fight against the wall—if the old man can't find anything, the Sophora japonica project may really have to be written, which should actually be an ellipsis, followed by a string of unsolved puzzle.

Afraid of attracting the attention of the provincial department, they still didn't drive when they went out this time. They took a taxi to the Weini Community on Linquan North Road, went to the property office, explained that the police investigated the case, and obtained the specific unit number of Jiang Jianzhou.

Before coming here, Chu Yu was already familiar with some of his information. For example, his spouse had passed away, and he had a son and a daughter, both of whom were over [-] years old. He had his own family, and he was now living alone.

When they reached the downstairs of the unit building, Song Qingyang was waiting outside, while Chu Yu and Mu Yu went upstairs and knocked on the door.

After a while, a questioning voice came from inside: "Who is it?"

Chu Yu showed the police officer's certificate, knowing that he should be able to see it inside: "Mr. Jiang, hello, we are policemen from the Wangjiang City Public Security Bureau, and we are in charge of investigating an important case. I want to ask you something, can I open the door?"

The door was quiet for a few seconds, and Chu Yu was about to speak again, but the door opened, and Jiang Jianguo stood behind the door and welcomed them in.

The first impression he gave people was that he was tall and slender, with gray hair but neatly groomed, he was a fine old man.Chu Yu has seen the photos of him when he was young, he looks dignified and majestic, although he is gone now and his back is a bit bent, but his temperament is still preserved.

After Chu Yu and Mu Yu were seated, the old man made tea for them, as if receiving distinguished guests.

The two of them sat in the middle of the sofa, and Jiang Jianzhou sat on the side. He didn't look nervous, and smiled amiably: "Hi, police officers, what do you want to ask?"
