"Ah sneeze ......" when waiting for the traffic light, Yang Yan, who was sitting in the driver's seat, couldn't help but sneeze twice, in order to prevent the flu virus from affecting the car, he hurriedly opened the windows on both sides, ventilated a little, and then closed it.

"Is there really no problem? Why don't you stay at home with Luoluo and rest, tell me how to use these devices, and I'll go by myself." Xia Yu stretched out his hand from the back seat, put it on Yang Yan's backrest, and asked worriedly.

"It's okay, it's just a small cold, and a minor injury can't get out of the line of fire!" Yang Yan sniffed his nose to make his nose clearer, and then smiled.

Xia Yu couldn't resist him, so he had to sit back again.

Yang Yan and Xia Yu continued to discuss the case, and he asked with some puzzlement: "Within three months, Aunt Li transferred and remitted 13,000 yuan to this Xiao Wang one after another, and the account number of this transfer is different every time, doesn't Aunt Li feel strange?"

"This deception is not clever, I also feel this way, but Aunt Li can't believe her doubts. Xia Yu sighed, "Didn't the promotional materials say 'if you are not greedy, you will not be deceived'? I think Aunt Li has been deceived so many times in a row, also because she is still lucky, thinking that she can still get the subsidy of 70,000 yuan!"

"Well, that's right! The social security scam that our family encountered before also caught the greed for cheapness that many people have! If they didn't want to get these benefits that didn't belong to them at the beginning, I don't think they would have been deceived!" Yang Yan nodded lightly.

"That being said, these bastards who cheated the old man out of money are too hateful! The old man worked hard to save so little money, and they all wanted to cheat them out regardless of whether others lived or died!" Xia Yu said indignantly.

Luoluo was originally sitting in a child safety seat, happily looking out the window, but at this moment, her mother's excited tone attracted the little girl's attention.

She turned her little head and looked at her mother a little blankly. The mother's indignant expression was reflected in the little girl's innocent and pure eyes, as if forming a sharp contrast.

The little girl, who can't accurately judge other people's emotions, has begun to be ignorant and trying to understand the expressions of adults...... So, Luoluo misunderstood, she thought that her mother was angry and quarreling with her father!

It's really a bit like, if the voices of Xia Yu and Yang Yan are blocked, just looking at Xia Yu's frowning and patting his thighs, I'm afraid the viewers will also think that they are quarreling, right?

Xia Yu and Yang Yan were still discussing the case, and she asked: "By the way, I may not have expressed it clearly enough in yesterday's text message, and I will tell you a suspicious point, that is, the little Wang who called Aunt Li, knew that Aunt Li had rheumatism at the beginning!"

"He knows?" Yang Yan was slightly surprised.

"Yes, I also specifically asked Aunt Li, this matter is not that she was tricked, but from the first phone call, they knew, and Aunt Li also because their concern happened to fit their own situation, so they gradually believed their sweet words!" Xia Yu said, "Do you think this is a clue? You say, is it possible that an acquaintance committed the crime?"

When Xia Yu was talking at length, Luoluo pouted her little mouth, her nose made an anxious "hum" sound, and she stretched out her little hand with her mother.

The mantis arm is used as a car, and the little girl seems to want to use her short and small arms to stop her mother who is "quarreling" with her father!

Xia Yu didn't know Luoluo's thoughts yet, she reached out a little absentmindedly, first touched Luoluo's little head, as if to soothe it, and then she grabbed Luoluo's little hand, but turned her head back to Yang Yan, she was waiting for Yang Yan to help her analyze the case.

"It's hard to say, there are acquaintances who cheat money in pyramid schemes, but Aunt Li is facing more like telecom fraud. Yang Yan combined with the research he had done before and analyzed with Xia Yu, "And you also said before that Aunt Li received a letter with her name printed on it, I think it is very likely that her personal information has been leaked!"

"Personal information leaked?" Xia Yu asked suspiciously.

"Yes, for example, Aunt Li may have registered her personal information in some medical structures before, and in some underground channels, the information of these hospitals, or the courier information, is sold at a clear price!" Yang Yan said to Xia Yu.

He has also learned about similar transactions on the dark web, and knows that even if it is not the dark web, there is such a situation in reality, otherwise, how can we often receive some inexplicable text messages on our mobile phones?

"Someone buys and sells this personal information?" Xia Yu asked in surprise, "Isn't this illegal?"

"This is indeed a crime, but this related law has only been proposed in the past two years, and there is no relatively perfect evaluation standard and sentencing standard. Even most people don't know that this is a crime!" Yang Yan shook his head lightly and sighed, "So there are still many people who do such things openly and secretly, but few people can care." ”

Dad was there to talk at length, and Luoluo, who had been focusing on her mother, found that her mother hadn't paid attention to herself, and she was a little unhappy!

The little girl even forgot why she wanted to stop her mother just now, even if her mother didn't act as angry as she did just now, and her mother and father were still chatting energetically, and there was no quarrel at all, but the little girl was still thinking about her "mission" of fighting!

I saw that Luo Luo twisted on her child safety seat, and her little buttocks arched hard, but she was restrained by the seat belt and couldn't struggle out...... Mommy, Mommy, Mommy......"

The little girl screamed very anxiously, intermittently, and with some coquettish tone.

"Isn't Mom holding your hand?" Xia Yu had no choice but to stop, turned her head and smiled at the little girl, she held her little hand, and asked affectionately, "Are you going to pee?"

Luoluo is still wearing diapers, but recently she seems to have sprouted some active awareness, if there is a more obvious feeling of wanting to pee is discovered by her, she will tell her father or mother.

Of course, Luoluo didn't have this idea now, and when she heard her mother ask herself, the little girl pouted and shook her head, indicating no.

But with her mother's concern, Luoluo's little emotion just now soon disappeared, and after a while, she "hum, hum", showing a happy and sweet smile. The little girl turned her head to look outside again, as if her mission had been accomplished, and she looked at the scenery outside the car with joy.

......

It is not easy to trace the source of the information leak, and neither Yang Yan nor Xia Yu chose to start here.

Tracing the information of the receiving bank account is a better choice, and many telecom fraud cases are investigated and solved from this breakthrough!

But this is a matter for the police, and after Xia Yu handed over the registration book to Chen Zhe, they will also trace it based on the bank account information on the record.

However, this is also a very unsafe method, it takes too long, it is easy to startle the snake, if those fraudsters find out, escape, even if they find the bank information, it is difficult to arrest them.

You know, fraudsters aren't stupid enough to wait for the bank to freeze the account, they must quickly transfer out every money they receive!

If you can't catch people, especially the mastermind, Aunt Li and other deceived people will not be able to recover the losses they have suffered!

This is not the result Xia Yu wants to see!

Therefore, Yang Yan and Xia Yu quickly rushed to Aunt Li Qiongzhen's house, and Yang Yan brought some equipment, including computers, wireless routers, and some strange signal detection equipment.

Under the gaze of Xia Yu and Aunt Li, Yang Yan placed them on the table one by one.
