According to he Xingping's account, Gu Chen basically knows why Wang Guifang's bank card cash was suddenly stolen and swiped without operation.
can say that in this case, the sniffer device used by criminal suspect He Xingping is very cheap.
As for the sniffer technology, it is not a high-tech technology, but why can it be used repeatedly?
Gu Chen naturally needs to reflect.
He Xingping, who was arrested, also took the initiative to confess: "you register information with your real name on some apps. Most of the time, it is convenient for you."
"But when you forget your password, you can log in through the SMS verification code. You will feel very convenient at this time."
"At the same time, it is convenient for us to steal your personal information and log in through this verification code, which is convenient for you and me."
"Yes, convenient payment is really a double-edged sword." Gu Chen also admits this.
What he Xingping said is exactly the loophole of mobile payment.
In addition, officer Wang randomly selected several commonly used apps on the mobile phone for testing. These apps can be logged in through user name plus password, and mobile phone number plus dynamic verification code.
When the user forgets the password, the password can be retrieved by sending the verification code through the mobile phone number.
All this seems to be very convenient and safe for users.
However, lawbreakers can also log in conveniently by using their mobile phone number and dynamic verification code. They can choose to input the user's mobile phone number on their mobile phones or computers in the dead of the night when people's awareness of anti-counterfeiting is relatively low.
Then the intercepted dynamic verification code is used to login the user's app to achieve the purpose of stealing user's funds.
However, the way to add CAPTCHA to mobile phones is probably the most popular method now, especially in cyberspace, which is commonly used by many apps.
And it's not about one or two, it's a pass through verification.
But this kind of verification method itself has certain security risks.
In other words, the captcha may be intercepted, which is one of them.
The second one is the reserved mobile phone number. In fact, the possibility of leakage of this number is very large.
Therefore, there are certain loopholes in the combination of these two methods to make a unique verification method.
Gu Chen is very clear that operators and banks should try their best to supplement other verification methods.
Not only that, many Internet companies do not protect users' personal information very well.
When you log in many apps and use many mobile services, each mobile service requires individuals to provide some personal data.
So when people enter so many places and use so many purposes, almost all the information is backed up in every node of the Internet.
But any of these backup lost, leaked, etc., will cause the loss of all personal data.
because the suspect can deliberately interfere with the mobile phone signal, which will enable 4G and 5G mobile phone to 2G network.
However, it is hard to make up for the inherent deficiency of 2G network.
This requires many Internet companies and banks, can not use mobile phone plus dynamic verification code as the only way of authentication.
Other verification methods should be added as much as possible.
At the same time, ordinary users should also strengthen personal prevention.
Seeing Gu Chen has been writing a draft on the transcript, Lu Weiwei can't help but stretch her neck.
Gu Chen in the inquiry he Xingping at the same time, has begun to work to prevent leakage of the draft program.
After glancing at he Xingping, Gu Chen asked again, "your sniffing technology should be very difficult to deal with."
"If it's you, from your own point of view, is there any suitable way to stop it? I'd like to hear your opinion."
Gu Chen really needs to listen to he Xingping.
From different angles, the party who committed the crime often has a more macroscopic view than the victim.
He Xingping nodded: "if the best way is to say, if you want to bind a bank card of a third-party platform, try not to put too much money into it."
"That is to say, poverty can prevent theft?" Officer Wang suddenly felt deeply.
After so many years of mixing, I suddenly realized that poverty is not bad, at least not afraid of thieves. It is true.
He Xingping was also stunned. He then nodded: "bad That's almost what it means
Gu Chen understood the situation of the scene, then took out the handcuffs and directly tortured he Xingping: "please come back with us to Furong Branch Office for investigation."
……
……
After he Xingping was brought back to Furong Branch Office, the equipment that he Xingping rented out for debugging was also brought back.
Gu Chen gives these to he Junchao and asks him to sort out the data.At the same time, Wang Guifang, who had been waiting for a long time in the office of the third group of Furong Branch Bureau, also got the 50000 yuan cash that was lost, and the whole person's jaw almost fell there.
She took Gu Chen's hand and said, "officer Gu, thank you very much. I didn't expect that my stolen cash could be recovered so soon. Did you raise your efficiency?"
"It's OK. I wish the cash can be recovered..."
Before Gu Chen's voice dropped, Wang Guifang immediately interrupted: "I've heard that it takes a long time to recover such a situation as mine. For example, as a good friend of mine, tens of thousands of yuan were lost by telecom fraud last year, and it has not been recovered yet."
"In fact, I really don't care about the 50000 yuan. I just think that the card still has so much cash. If it's stolen one day, I'll be in big trouble."
"I know." Gu Chen also reached out and interrupted Wang Guifang's words and continued to warn: "but I want to remind you that your name, mobile phone number, dynamic SMS verification code, ID card information and bank card account number have been mastered. It is suggested that you change these information immediately to avoid the same situation again."
"You I beg your pardon? My name? And these cell phone numbers, bank cards and so on. How can these things be known by others? "
Gu Chen couldn't give her a detailed explanation, so he reorganized his language and said, "let's just tell you, your cell phone signal is interfered by people and directly becomes 2G signal." Put all sorts of things together, and
"and the suspect use the loopholes of 2G signals to catch your mobile phone numbers and dynamic verification code, and then use these to log on all social APP you registered, and use these login accounts to gather together to catch your other information."
"this includes your ID card number, name, and bank card information."
"through these data, the suspect can accurately control your income, so that if you do not strengthen the prevention now, I am afraid that the theft will happen again."
"Really Is that terrible? "
Listening to Gu Chen's explanation, Wang Guifang suddenly panicked.
You know, you are a rich woman at least. Now the identity information is completely mastered by criminals.
In this way, I have become a cash machine for criminals.
Thinking of this, Wang Guifang almost cried: "officer Gu, that What should I do? What should I do? "
"Don't worry." Gu Chen had long anticipated Wang Guifang's reaction, so he suggested: "if you want to bind the bank card of a third-party platform, try not to put too much money into it."
"It's because criminals are taking advantage of secret payment, that is, the vulnerability that SMS verification codes can pay for, so they can brush your money away."
"Therefore, you should try not to put too much money into the bank card of the third-party platform that is bound."
"Well, I'll take your advice." Wang Guifang suddenly nodded like a chicken peck, and a group of worried hearts asked, "what else should I pay attention to besides this?"
Gu Chen thought about it, and then said, "if you suddenly receive an unknown verification code, and then find that the bank card has been stolen, don't panic."
"The first thing you think of is to go to the public security organ and stop payment in time, and report the loss of your bank card and freeze it."
"The next thing is for the public security organs to help you recover the money. Do you understand?"
"Ming Yes, I understand. " Of course, Wang Guifang understood that she might be about to change from a rich woman to a negative one.
Zhang Peijun, the vice president of the bank, said in dismay: "I didn't expect it. I really didn't expect that these criminals are now more and more skillful in committing crimes. It's impossible to prevent them."
After looking at Wang Guifang, Zhang Peijun then said: "sister Wang, I have said that this must have nothing to do with our bank. There must be something wrong with it. You see, you left the responsibility to our bank at the beginning and let so many customers see it. It's really difficult for us to do it."
Wang Guifang is also smiling at the moment, quickly to Zhang Peijun compensation is not: "brother Zhang, is your sister Wang reckless, to your bank brought such a negative impact."
"But I was in a hurry at that time. After all, the bank card was stolen for no reason. If it was your bank, I had to guard against it."
"After all, in recent years, is it still rare for your bank leaders to secretly move customers' funds to stock market and buy funds?"
Asked by Wang Guifang, Zhang Peijun was speechless.
Indeed, what Wang Guifang said is also true. In recent years, various kinds of bank leaders embezzled the customer's book funds to do private work frequently, which also became a social hot spot for a time.
Wang Guifang used this move to talk. Zhang Peijun did not say anything. He could only happily nod his head and say, "sister Wang, you are right, but that is a minority after all."
"It's impossible that a mouse poop will spoil the whole pot of porridge, will it? This situation will never happen in our bank. We fully abide by professional ethics. With Zhang Peijun in the bank, you can make efforts to deposit money and loan. ""Yes, I believe in your brother." Wang Guifang did not seem so angry.
Before, they were still shouting in the bank hall about who was right and who was wrong. Now Gu Chen recovered Wang Guifang's stolen funds, and Wang Guifang was naturally happy.
Gu Chen also told her to take remedial measures. Wang Guifang's first problem now is to set the bound third-party payment bank card to a small amount, which naturally requires Zhang Peijun to operate.
After thanking Gu Chen and all three police officers, Wang Guifang left Furong Branch with Zhang Peijun.
Seeing this, he Junchao could not help asking Gu Chen: "by the way, group leader Gu, how do you deal with he Xingping who you arrested? Do you want to get rid of the guy he's in direct contact with? "
"Leave that alone." Gu Chen directly stopped: "although this case is not big, but the problems reflected deserve our attention."
"And pull out the radish and bring out the pit. This industrial chain is not so simple. He Xingping is only a small role. We must rely on him to dig out the whole industry chain."
Officer Ding frowned and asked Gu Chen, "what do you say?"
"I'm preparing a material. I want to sort out the information about this problem directly and send it to the email address of Zhaoju. I think the Zhaoju bureau should be interested in it."
"That's best." Police officer Ding also agreed with Gu Chen's statement, so he said: "it's hard to work group leader Gu. Hurry up. If you need help, talk to our brothers."
"I don't need it now. I think it will be soon." Gu Chen will sit at his desk and begin to prepare the report materials.
After that, the third criminal investigation team will be the absolute main force in handling cases.
At the same time, it also needs the full cooperation of other departments of Furong Branch Bureau.
Gu Chen, who knows this well, needs a complete report to Zhao Guozhi, so that he can get a little command from Zhao Guozhi, so as to mobilize other departments to help handle the case.
In the office, we repeatedly browse Gu Chen's investigation record, and suddenly feel that the sniffing technology is a little terrible.
After a few cheap laptops, the police officer would be surprised to find a cheap laptop
"That's it." Yuan Shasha also thought carefully and said: "in this way, our personal information is like the water in the pool. Every time we use an Internet service, it is like installing a pipeline in the pool, which increases the risk of leakage."
"What's worrying is that many pipes use the same kind of tap, that is, the mobile phone number plus dynamic verification code." Lu Weiwei adds, let everybody hear more understand.
"The current environment is much better than we used to be, but there are more and more cyber crimes," Wang said
"And the reason why these illegal elements can succeed is to take advantage of various loopholes in network technology."
"I hope these telecom operators, Internet companies, banks and regulatory authorities can think more about ways to effectively protect the property safety of the people," he said with a curled mouth
"After all, there's no point without security and convenience."
"Isn't this something banks and network operators should consider strengthening?" There are also probation police.
Soon, the scene became extraordinarily noisy.
A group of police officers with thousands of dollars' wages are beginning to worry about the safety of the property of these multimillionaires.
Lu Weiwei raised her hand and said, "and there are also major apps. Since you want to have permissions, you should not be a shrinking turtle when privacy is leaked."
"Yes." Yuan Shasha also raised her hand in praise: "sometimes, they really let you feel the sense of desperation that they shirk responsibility."
"That should let the operator compensate." He Junchao slapped the table, but also filled with indignation: "who let their base station so unclassified, not only have to pay compensation, but also a huge fine, saving this group of people to push all kinds of network packages all day long, that is, doing nothing."
"Ha ha, it's so terrible that ordinary people can't defend against this kind of thing. Inexplicably, text messages come and money is drawn away. How to prevent it? Only the operators can strengthen the prevention. " A female probationary police officer is not from the point said.
Soon, everyone's discussion also entered the white hot.
During the debate, many members of the other three groups were in the office.
Of course, Gu Chen is also very aware of the seriousness of this kind of thing.
Because sniffer technology, objectively speaking, is really the kind of defense that we say is impossible to defend.
And from the investigation of he Xingping, we can see that he is only a small role.
It can be seen that in the whole Jiangnan City, it seems that this criminal gang has appeared.
To find this criminal gang, and to capture the core, is clearly a fierce battle.
After analyzing the pros and cons in the report, Gu Chen rechecked it and sent it to Zhao Guozhi by email.
And Zhao Guozhi also has a tradition that has always been preserved, that is, before leaving work, he must read his work mailbox before going home.We should report the work of all police officers of Furong sub bureau to the end of the day.
Zhao Guozhi will know the situation immediately if there is something urgent to be solved.
Zhao Guozhi will take the next morning to solve the problems that are not difficult.
This is the bridge between Zhao Guozhi and many police officers of Furong Branch, and has been popular with all the time.
After returning his analysis report, Gu Chen stretched himself and moved his muscles and bones.
Seeing that everyone is still discussing, Gu Chen picks up the water cup and goes directly to the water dispenser to pour hot water.
Police officer Ding also complained to Gu Chen: "I said Gu Chen, now personal privacy leakage is really serious."
"For example, every time I receive a variety of sales calls, I feel very shocked. I want to ask where the privacy has been leaked, but I don't know who to scold. It is estimated that the bank's grandsons leaked out, especially the secret payment. Although convenient, it has many loopholes."
"Senior brother Ding." It seems that Tucao bank is very excited. Gu Chen is also a way to make complaints about the language:
, "objectively speaking, I remember that banks had to transfer money before they had to use net silver shield, and they could not do with the verification code. This is a good thing for people to do."
"But after mobile payment became popular, you can transfer money without using online silver shield. It's more convenient and faster if you have a verification code."
"I think that later, the banks should also be forced by the pressure of competition, which leads to the fact that some mobile phone verification codes are bound now, so the banks can't be entirely blamed."
"Yes, I think what elder martial brother Gu said is very objective." Yuan Shasha also very much agreed with Gu Chen's opinion, and continued: "after all, society is progressing, banks are strengthening confidentiality, and cheaters are also studying how to crack it. This is the relationship between spear and shield. Only when there is mutual pressure can progress be made."
"It's no use." He Junchao has always been a pessimist. He make complaints about operators for many years, and directly Tucao:
, "now those operators do not say that they are protected. Some of them will sell your information. All kinds of sales calls are those people sell."

"I think that later, the banks should also be forced by the pressure of competition, which leads to the fact that some mobile phone verification codes are bound now, so the banks can't be entirely blamed."
"Yes, I think what elder martial brother Gu said is very objective."

"It's no use." He Junchao has always been a pessimist. He make complaints about operators for many years, and directly Tucao:

According to he Xingping's account, Gu Chen basically knows why Wang Guifang's bank card cash was suddenly stolen and swiped without operation. can say that in this case, the sniffer device used by criminal suspect He Xingping is very cheap. As for the sniffer technology, it is not a high-tech technology, but why can it be used repeatedly? Gu Chen naturally needs to reflect. He Xingping, who was arrested, also took the initiative to confess: "you register information with your real name on some apps. Most of the time, it is convenient for you." "But when you forget your password, you can log in through the SMS verification code. You will feel very convenient at this time." "At the same time, it is convenient for us to steal your personal information and log in through this verification code, which is convenient for you and me." "Yes, convenient payment is really a double-edged sword." Gu Chen also admits this. What he Xingping said is exactly the loophole of mobile payment. In addition, officer Wang randomly selected several commonly used apps on the mobile phone for testing. These apps can be logged in through user name plus password, and mobile phone number plus dynamic verification code. When the user forgets the password, the password can be retrieved by sending the verification code through the mobile phone number. All this seems to be very convenient and safe for users. However, lawbreakers can also log in conveniently by using their mobile phone number and dynamic verification code. They can choose to input the user's mobile phone number on their mobile phones or computers in the dead of the night when people's awareness of anti-counterfeiting is relatively low. Then the intercepted dynamic verification code is used to login the user's app to achieve the purpose of stealing user's funds. However, the way to add CAPTCHA to mobile phones is probably the most popular method now, especially in cyberspace, which is commonly used by many apps. And it's not about one or two, it's a pass through verification. But this kind of verification method itself has certain security risks. In other words, the captcha may be intercepted, which is one of them. The second one is the reserved mobile phone number. In fact, the possibility of leakage of this number is very large. Therefore, there are certain loopholes in the combination of these two methods to make a unique verification method. Gu Chen is very clear that operators and banks should try their best to supplement other verification methods. Not only that, many Internet companies do not protect users' personal information very well. When you log in many apps and use many mobile services, each mobile service requires individuals to provide some personal data. So when people enter so many places and use so many purposes, almost all the information is backed up in every node of the Internet. But any of these backup lost, leaked, etc., will cause the loss of all personal data. because the suspect can deliberately interfere with the mobile phone signal, which will enable 4G and 5G mobile phone to 2G network. However, it is hard to make up for the inherent deficiency of 2G network. This requires many Internet companies and banks, can not use mobile phone plus dynamic verification code as the only way of authentication. Other verification methods should be added as much as possible. At the same time, ordinary users should also strengthen personal prevention. Seeing Gu Chen has been writing a draft on the transcript, Lu Weiwei can't help but stretch her neck. Gu Chen in the inquiry he Xingping at the same time, has begun to work to prevent leakage of the draft program. After glancing at he Xingping, Gu Chen asked again, "your sniffing technology should be very difficult to deal with." "If it's you, from your own point of view, is there any suitable way to stop it? I'd like to hear your opinion." Gu Chen really needs to listen to he Xingping. From different angles, the party who committed the crime often has a more macroscopic view than the victim. He Xingping nodded: "if the best way is to say, if you want to bind a bank card of a third-party platform, try not to put too much money into it." "That is to say, poverty can prevent theft?" Officer Wang suddenly felt deeply. After so many years of mixing, I suddenly realized that poverty is not bad, at least not afraid of thieves. It is true. He Xingping was also stunned. He then nodded: "bad That's almost what it means Gu Chen understood the situation of the scene, then took out the handcuffs and directly tortured he Xingping: "please come back with us to Furong Branch Office for investigation." After he Xingping was brought back to Furong Branch Office, the equipment that he Xingping rented out for debugging was also brought back. Gu Chen gives these to he Junchao and asks him to sort out the data.At the same time, Wang Guifang, who had been waiting for a long time in the office of the third group of Furong Branch Bureau, also got the 50000 yuan cash that was lost, and the whole person's jaw almost fell there. She took Gu Chen's hand and said, "officer Gu, thank you very much. I didn't expect that my stolen cash could be recovered so soon. Did you raise your efficiency?" "It's OK. I wish the cash can be recovered..." Before Gu Chen's voice dropped, Wang Guifang immediately interrupted: "I've heard that it takes a long time to recover such a situation as mine. For example, as a good friend of mine, tens of thousands of yuan were lost by telecom fraud last year, and it has not been recovered yet." "In fact, I really don't care about the 50000 yuan. I just think that the card still has so much cash. If it's stolen one day, I'll be in big trouble." "I know." Gu Chen also reached out and interrupted Wang Guifang's words and continued to warn: "but I want to remind you that your name, mobile phone number, dynamic SMS verification code, ID card information and bank card account number have been mastered. It is suggested that you change these information immediately to avoid the same situation again." "You I beg your pardon? My name? And these cell phone numbers, bank cards and so on. How can these things be known by others? " Gu Chen couldn't give her a detailed explanation, so he reorganized his language and said, "let's just tell you, your cell phone signal is interfered by people and directly becomes 2G signal." Put all sorts of things together, and "and the suspect use the loopholes of 2G signals to catch your mobile phone numbers and dynamic verification code, and then use these to log on all social APP you registered, and use these login accounts to gather together to catch your other information." "this includes your ID card number, name, and bank card information." "through these data, the suspect can accurately control your income, so that if you do not strengthen the prevention now, I am afraid that the theft will happen again." "Really Is that terrible? " Listening to Gu Chen's explanation, Wang Guifang suddenly panicked. You know, you are a rich woman at least. Now the identity information is completely mastered by criminals. In this way, I have become a cash machine for criminals. Thinking of this, Wang Guifang almost cried: "officer Gu, that What should I do? What should I do? " "Don't worry." Gu Chen had long anticipated Wang Guifang's reaction, so he suggested: "if you want to bind the bank card of a third-party platform, try not to put too much money into it." "It's because criminals are taking advantage of secret payment, that is, the vulnerability that SMS verification codes can pay for, so they can brush your money away." "Therefore, you should try not to put too much money into the bank card of the third-party platform that is bound." "Well, I'll take your advice." Wang Guifang suddenly nodded like a chicken peck, and a group of worried hearts asked, "what else should I pay attention to besides this?" Gu Chen thought about it, and then said, "if you suddenly receive an unknown verification code, and then find that the bank card has been stolen, don't panic." "The first thing you think of is to go to the public security organ and stop payment in time, and report the loss of your bank card and freeze it." "The next thing is for the public security organs to help you recover the money. Do you understand?" "Ming Yes, I understand. " Of course, Wang Guifang understood that she might be about to change from a rich woman to a negative one. Zhang Peijun, the vice president of the bank, said in dismay: "I didn't expect it. I really didn't expect that these criminals are now more and more skillful in committing crimes. It's impossible to prevent them." After looking at Wang Guifang, Zhang Peijun then said: "sister Wang, I have said that this must have nothing to do with our bank. There must be something wrong with it. You see, you left the responsibility to our bank at the beginning and let so many customers see it. It's really difficult for us to do it." Wang Guifang is also smiling at the moment, quickly to Zhang Peijun compensation is not: "brother Zhang, is your sister Wang reckless, to your bank brought such a negative impact." "But I was in a hurry at that time. After all, the bank card was stolen for no reason. If it was your bank, I had to guard against it." "After all, in recent years, is it still rare for your bank leaders to secretly move customers' funds to stock market and buy funds?" Asked by Wang Guifang, Zhang Peijun was speechless. Indeed, what Wang Guifang said is also true. In recent years, various kinds of bank leaders embezzled the customer's book funds to do private work frequently, which also became a social hot spot for a time. Wang Guifang used this move to talk. Zhang Peijun did not say anything. He could only happily nod his head and say, "sister Wang, you are right, but that is a minority after all." "It's impossible that a mouse poop will spoil the whole pot of porridge, will it? This situation will never happen in our bank. We fully abide by professional ethics. With Zhang Peijun in the bank, you can make efforts to deposit money and loan. ""Yes, I believe in your brother." Wang Guifang did not seem so angry. Before, they were still shouting in the bank hall about who was right and who was wrong. Now Gu Chen recovered Wang Guifang's stolen funds, and Wang Guifang was naturally happy. Gu Chen also told her to take remedial measures. Wang Guifang's first problem now is to set the bound third-party payment bank card to a small amount, which naturally requires Zhang Peijun to operate. After thanking Gu Chen and all three police officers, Wang Guifang left Furong Branch with Zhang Peijun. Seeing this, he Junchao could not help asking Gu Chen: "by the way, group leader Gu, how do you deal with he Xingping who you arrested? Do you want to get rid of the guy he's in direct contact with? " "Leave that alone." Gu Chen directly stopped: "although this case is not big, but the problems reflected deserve our attention." "And pull out the radish and bring out the pit. This industrial chain is not so simple. He Xingping is only a small role. We must rely on him to dig out the whole industry chain." Officer Ding frowned and asked Gu Chen, "what do you say?" "I'm preparing a material. I want to sort out the information about this problem directly and send it to the email address of Zhaoju. I think the Zhaoju bureau should be interested in it." "That's best." Police officer Ding also agreed with Gu Chen's statement, so he said: "it's hard to work group leader Gu. Hurry up. If you need help, talk to our brothers." "I don't need it now. I think it will be soon." Gu Chen will sit at his desk and begin to prepare the report materials. After that, the third criminal investigation team will be the absolute main force in handling cases. At the same time, it also needs the full cooperation of other departments of Furong Branch Bureau. Gu Chen, who knows this well, needs a complete report to Zhao Guozhi, so that he can get a little command from Zhao Guozhi, so as to mobilize other departments to help handle the case. In the office, we repeatedly browse Gu Chen's investigation record, and suddenly feel that the sniffing technology is a little terrible. After a few cheap laptops, the police officer would be surprised to find a cheap laptop "That's it." Yuan Shasha also thought carefully and said: "in this way, our personal information is like the water in the pool. Every time we use an Internet service, it is like installing a pipeline in the pool, which increases the risk of leakage." "What's worrying is that many pipes use the same kind of tap, that is, the mobile phone number plus dynamic verification code." Lu Weiwei adds, let everybody hear more understand. "The current environment is much better than we used to be, but there are more and more cyber crimes," Wang said "And the reason why these illegal elements can succeed is to take advantage of various loopholes in network technology." "I hope these telecom operators, Internet companies, banks and regulatory authorities can think more about ways to effectively protect the property safety of the people," he said with a curled mouth "After all, there's no point without security and convenience." "Isn't this something banks and network operators should consider strengthening?" There are also probation police. Soon, the scene became extraordinarily noisy. A group of police officers with thousands of dollars' wages are beginning to worry about the safety of the property of these multimillionaires. Lu Weiwei raised her hand and said, "and there are also major apps. Since you want to have permissions, you should not be a shrinking turtle when privacy is leaked." "Yes." Yuan Shasha also raised her hand in praise: "sometimes, they really let you feel the sense of desperation that they shirk responsibility." "That should let the operator compensate." He Junchao slapped the table, but also filled with indignation: "who let their base station so unclassified, not only have to pay compensation, but also a huge fine, saving this group of people to push all kinds of network packages all day long, that is, doing nothing." "Ha ha, it's so terrible that ordinary people can't defend against this kind of thing. Inexplicably, text messages come and money is drawn away. How to prevent it? Only the operators can strengthen the prevention. " A female probationary police officer is not from the point said. Soon, everyone's discussion also entered the white hot. During the debate, many members of the other three groups were in the office. Of course, Gu Chen is also very aware of the seriousness of this kind of thing. Because sniffer technology, objectively speaking, is really the kind of defense that we say is impossible to defend. And from the investigation of he Xingping, we can see that he is only a small role. It can be seen that in the whole Jiangnan City, it seems that this criminal gang has appeared. To find this criminal gang, and to capture the core, is clearly a fierce battle. After analyzing the pros and cons in the report, Gu Chen rechecked it and sent it to Zhao Guozhi by email. And Zhao Guozhi also has a tradition that has always been preserved, that is, before leaving work, he must read his work mailbox before going home.We should report the work of all police officers of Furong sub bureau to the end of the day. Zhao Guozhi will know the situation immediately if there is something urgent to be solved. Zhao Guozhi will take the next morning to solve the problems that are not difficult. This is the bridge between Zhao Guozhi and many police officers of Furong Branch, and has been popular with all the time. After returning his analysis report, Gu Chen stretched himself and moved his muscles and bones. Seeing that everyone is still discussing, Gu Chen picks up the water cup and goes directly to the water dispenser to pour hot water. Police officer Ding also complained to Gu Chen: "I said Gu Chen, now personal privacy leakage is really serious." "For example, every time I receive a variety of sales calls, I feel very shocked. I want to ask where the privacy has been leaked, but I don't know who to scold. It is estimated that the bank's grandsons leaked out, especially the secret payment. Although convenient, it has many loopholes." "Senior brother Ding." It seems that Tucao bank is very excited. Gu Chen is also a way to make complaints about the language: , "objectively speaking, I remember that banks had to transfer money before they had to use net silver shield, and they could not do with the verification code. This is a good thing for people to do." "But after mobile payment became popular, you can transfer money without using online silver shield. It's more convenient and faster if you have a verification code." "I think that later, the banks should also be forced by the pressure of competition, which leads to the fact that some mobile phone verification codes are bound now, so the banks can't be entirely blamed." "Yes, I think what elder martial brother Gu said is very objective." Yuan Shasha also very much agreed with Gu Chen's opinion, and continued: "after all, society is progressing, banks are strengthening confidentiality, and cheaters are also studying how to crack it. This is the relationship between spear and shield. Only when there is mutual pressure can progress be made." "It's no use." He Junchao has always been a pessimist.
