step S132, inserting a preset counter code into the fraud website file;
step S133, triggering the counter code according to a website login instruction of a fraud website manager;
step S134, obtaining the fraud account data based on the counter code.
In the step S134, the fraudulent account data may be encrypted and transmitted back to the analysis server for analysis in step S135.
If the fraud account data cannot be successfully acquired through the steps S131 to S134, the following steps are continued:
step S136, acquiring account passwords of fraud website managers through disguised links;
step S137, logging in a fraud website from a background based on the account number and the password of the fraud website manager;
s138, deploying a reverse code;
step S139, triggering the counter code according to a website login instruction of a fraud website manager;
step S140, obtaining fraud account data based on the counter code.
After step S140, step S141 of encrypting the fraud account data back to the analysis server may be further performed.
The fraudster virtual identity information in the fraudster account data can be a QQ account, a Taobao account, a Baidu account, a Yiyi account, a weibo account and the like.
That is, the countermeasures disclosed in CN111865925A are intended to obtain the social networking numbers of the fraudsters, and cannot prevent the occurrence of fraud events, or even reduce the loss of the fraudsters.
It can be seen that the prior art is still in need of improvement and development.
Disclosure of Invention
In view of the above-mentioned shortcomings of the prior art, the present invention provides a fraud countercheck intercepting method, system and storage medium, which aims to solve the problems that the prior art can only obtain the network social number of a fraudster, cannot prevent the occurrence of fraud events, and cannot even reduce the loss of the fraudster.
The technical scheme of the invention is as follows:
a fraud countering interception method, comprising:
acquiring a fraud-related social account according to the user reporting data and the Internet data crawled by using a crawler technology, judging a fraud-related level of the acquired fraud-related social account, and dividing the fraud-related social account into: the confirmed fraud account and the fraud account to be confirmed;
and through an API (application programming interface) provided by a social software service provider, the confirmed fraud account is forbidden, a fraud warning plug-in is added aiming at the fraud account to be confirmed, and fraud warning is carried out on the social account communicated with the fraud account to be confirmed through the fraud warning plug-in.
The effect of above-mentioned scheme lies in: different from the existing countercheck method, the method can directly block the confirmed fraud account through the API provided by the social software service provider so as to prevent the fraud molecules from continuing to fraud through the fraud account; and adding fraud warning plug-ins to the fraud account to be confirmed through the API, so as to prevent the occurrence of fraud events, reduce the occurrence of fraud events at a high probability, and solve the problems that the prior art can only acquire the network social number of a fraud, cannot prevent the occurrence of fraud events, and even cannot reduce the loss of a scammed person.
In a further preferred aspect, the fraud early warning to the social account communicating with the fraud account to be confirmed by the fraud warning plug-in specifically comprises:
when detecting that the account number to be confirmed and the social account number have account transfer transaction for the first time or bank card information is sent, preventing the transaction from occurring or preventing the bank card information from being sent to the account number to be confirmed;
when detecting that the account number to be confirmed and the social account number perform transfer transaction for the second time or send bank card information, sending an early warning task to a fraud countercheck worker, and confirming whether the fraud countercheck worker is a fraud event to a suspected victim;
if so, preventing the transaction from occurring or preventing the bank card information from being sent to the fraud account number to be confirmed, marking the fraud account number to be confirmed as a confirmed fraud account number and carrying out sealing; and if not, marking the fraud account number to be confirmed as a suspected normal account number, and allowing the transaction to continue or allowing a bank card signal to be sent to the suspected normal account number.
The effect of above-mentioned scheme lies in: the account number to be confirmed is not determined as a fraud account number, the transaction can be fraud or normal transaction, when the transaction is first conducted or bank card information appears, the transaction is prevented from occurring or the bank card information is successfully sent, a suspected victim can be warned, when the suspected victim conducts the transaction again or the bank card information appears, whether the suspected victim is a fraud event or not can be confirmed manually, on one hand, when whether the suspected victim is the fraud event or not is not confirmed, the suspected victim is warned through technology, and if the suspected victim realizes the fraud event by himself, the workload of fraud countermakers is reduced and the fraud event is prevented from occurring; on the other hand, when the suspected victim insists on the transaction or sends the bank card information, the condition can be confirmed manually to accurately judge whether the transaction is a fraud event, if the transaction is confirmed to be the fraud event, the fraud event can be prevented from occurring and being continued to be deceived by blocking the fraud account, and if the transaction is confirmed to be a normal event, the completion of the event is not influenced by the method and the system.
In a further preferred scheme, the fraud account to be confirmed is divided into: the account number to be confirmed with high risk, the account number to be confirmed with medium risk and the account number to be confirmed with low risk; before the confirming of the suspected victim as a fraud event by the fraud counter-controller, the method further comprises: the computer end searches identity information of a suspected victim according to the data matching of the suspected victim social account, the risk level of the fraud account to be confirmed, the suspected victim social account and the fraud type, and respectively generates a high-risk fraud interception task, a medium-risk fraud interception task and a low-risk fraud interception task according to the identity information of the suspected victim and the risk level of the fraud account to be confirmed; the identity information includes: family name, gender, contact details, age, occupation, and whether or not they are fraudulently experienced.
The effect of above-mentioned scheme lies in: the occurrence of fraud events is basically irregular in time and position, and more fraud events are likely to occur in the same region in the same time period, when fraud events occur intensively or fraud countermakers cannot confirm and intercept the fraud events in time due to other conditions, under the condition of first transaction warning, the risk level is marked, so that the fraud countermakers preferentially contact suspected victims easy to cheat (people in different age groups are different in cheating degree, and people in different professions are also different in cheating degree), and the occurrence probability and loss of fraud events can be further reduced.
In a further preferred approach, said confirmation by the fraud counterfeiter to the suspected victim whether or not it is a fraudulent event is specifically: the method comprises the steps that a mobile phone end receives and displays an interception task list, receives an instruction of a fraud counter worker for receiving a current highest-risk interception task, and locks a selected interception task; when the fraud interception task is not picked up after the preset time, sending an early warning short message to warn suspected victims, sending task incompletion information to a computer terminal, and temporarily forbidding the fraud account to be confirmed by the computer terminal.
The effect of above-mentioned scheme lies in: when the tasks are too many or the fraud countermeasures have other tasks and are not picked up by people, on one hand, the suspected victim is warned through the early warning short message to ensure that the suspected victim can receive the early warning, and the occurrence probability and loss of fraud events are reduced; on the other hand, the computer end temporarily forbids the fraud account numbers to be confirmed so as to reduce or even avoid the property loss of suspected victims as much as possible.
In a further preferred scheme, the steps of blocking the confirmed fraud account and adding a fraud warning plug-in for the fraud account to be confirmed through an API interface provided by a social software service provider, and fraud warning to the social account in communication with the fraud account to be confirmed through the fraud warning plug-in further comprise: and receiving the type of the social account related to fraud, the type related to fraud, the number and the reason for countermeasures input by anti-fraud personnel in batches, and matching and calling an API (application programming interface) provided by the social software service provider according to the type of the social account related to fraud.
The effect of above-mentioned scheme lies in: the method for reverse control of the social account number by means of forbidding or adding fraud warning plug-ins and the like cannot be applied unscrupulously, and normal social contact of social users is easily influenced by false control, so that the method adopts a batch uploading mode after manual auditing, on one hand, the reverse control efficiency is improved, on the other hand, the reverse control accuracy is improved, and the false control probability is reduced.
In a further preferred embodiment, the step of obtaining a fraud-related social account according to the user reporting data and the internet data crawled by using a crawler technology, and determining a fraud-related level of the obtained fraud-related social account further includes: acquiring a fraud-related website and judging a fraud-related level of the acquired fraud-related website, wherein the fraud-related level comprises: the confirmed fraud websites and the fraud websites to be confirmed;
the steps of acquiring the fraud-related websites and judging the fraud-related level of the acquired fraud-related websites further comprise: and logging out the domain name resolution of the confirmed fraud websites through an API (application programming interface) provided by a server operator, and adding a fraud interception plug-in aiming at the fraud websites to be confirmed, wherein the fraud interception plug-in is used for locking a page when detecting that a user inputs bank card information until a fraud counter man manually issues a lock releasing instruction.
The effect of above-mentioned scheme lies in: in various fraud types, such as single-swiping fraud, loan fraud, impersonation common law fraud, sent fake wanted and other fraud types, a suspect sends a relevant website to a victim, and the victim basically performs website access by clicking. If the relevant case-related websites are countermarked, when the victim clicks and visits the relevant websites, the victim is prompted to be unable to visit or the websites are suspected to be reported for many times and are sealed, or the page is temporarily locked when the user inputs sensitive information such as a bank card and the like, so that the victim is prevented from browsing the relevant webpages, the victim can be warned, the possibility of being cheated is reduced, or whether the fraud is a fraud event is confirmed manually, on one hand, the countermarking efficiency is improved, on the other hand, the countermarking accuracy is improved, and the false sealing probability is reduced.
In a further preferred embodiment, the step of obtaining a fraud-related social account according to the user reporting data and the internet data crawled by using a crawler technology, and determining a fraud-related level of the obtained fraud-related social account further includes: acquiring a fraud-related mobile phone number and judging a fraud-related level of the acquired fraud-related mobile phone number, wherein the fraud-related level comprises: the confirmed fraud number and the fraud number to be confirmed;
the steps of acquiring the fraud-related mobile phone number and judging the fraud-related level of the acquired fraud-related mobile phone number further comprise: and locking the confirmed fraud numbers through an API (application program interface) provided by a communication operator, marking the fraud numbers to be confirmed as early warning numbers and sending the early warning numbers to a mobile phone end, and warning suspected victims through the mobile phone end.
The effect of above-mentioned scheme lies in: telecommunication fraud is cheated by calling and sending short messages at the earliest time, and then is developed into network number change, and with the popularization of the mobile internet, the proportion of crime made by using a network social tool rapidly rises; but the fraud modes of calling and sending short messages still occupy a larger proportion, the invention directly locks the confirmed fraud numbers through the API interface provided by the communication operator, and can prevent fraud molecules from continuously using the fraud numbers to cheat; and the marked fraud numbers to be confirmed are displayed through the mobile phone terminal, so that the suspects with fraud suspects can be prevented from carrying out fraud by using the fraud numbers to be confirmed to a certain extent, and the occurrence probability and loss of fraud events are reduced.

Detailed Description
The present invention provides a fraud countercheck intercepting method, system and storage medium, and in order to make the objects, technical schemes and effects of the present invention clearer and clearer, the present invention will be further described in detail below by referring to the attached drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention provides a fraud countercheck intercepting method, as shown in fig. 1, comprising:
s100, obtaining a fraud-related social account according to the user reporting data and the Internet data crawled by using a crawler technology, judging the fraud-related level of the obtained fraud-related social account, and dividing the fraud-related social account into: the confirmed fraud account and the fraud account to be confirmed.
Preferably, the method also receives the ecological data shared by the Internet companies and the joint anti-fraud laboratory warning situations of various regions so as to obtain the social account related to fraud; therefore, in a further preferred embodiment of the invention, the anti-fraud big data is acquired by combining the modes of user reporting, ecological data shared by internet companies, joint anti-fraud laboratory alarms in various regions, internet crawler technologies and the like, and by collecting and organizing various illegal websites, phishing websites, case-involved APPs, communication tools, VOS servers and other fraud-involved channels and means, the fraud-involved data and information data input by victims per se are acquired by utilizing the network technology to the websites, APP backgrounds and VOS servers of different fraud types.
In specific implementation, the fraud account to be confirmed is divided into: a high risk account to be confirmed, a medium risk account to be confirmed, and a low risk account to be confirmed.
S200, the confirmed fraud account is forbidden through an API (application programming interface) provided by a social software service provider, a fraud warning plug-in is added aiming at the fraud account to be confirmed, and fraud warning is carried out on the social account communicated with the fraud account to be confirmed through the fraud warning plug-in.
An API (application Program interface), i.e. an application Program interface, is a set of definitions, programs and protocols, and realizes mutual communication between computer software through the API interface, one main function of the API is to provide a general function set, and programmers can develop application programs by calling API functions, thereby reducing programming tasks. The API is also a middleware at the same time and provides data sharing for various platforms; by utilizing the characteristics of the API, fraud countermeasures (such as policemen and auxiliary policemen using fraud countermeasures systems) can directly block the confirmed fraud account without being checked layer by layer inside the social software service provider, so that the countermeasures efficiency of the fraud account is improved; similarly, the present invention also utilizes the characteristics, so that the fraud countermeasures can directly add fraud warning inserts to the fraud account to be confirmed, so as to prompt the suspected fraud molecules of the user opposite party in communication with the fraud account to be confirmed.
In a further preferred embodiment of the present invention, the fraud early warning to the social account communicating with the fraud account to be confirmed by the fraud warning plug-in specifically comprises:
and when detecting that the account number to be confirmed and the social account number have the transfer transaction for the first time or bank card information is sent, preventing the transaction from occurring or preventing the bank card information from being sent to the account number to be confirmed. For example, the account a is a fraud account to be confirmed, the fraud warning plug-in added in the invention monitors the behavior of the account a at any time, and when the account a is monitored to send information to other accounts (such as the account B), the suspected fraud-related information of the account a is displayed on the communication page, so that the probability of being cheated by the social user can be reduced; inevitably, part of users do not pay enough attention to the prompt information, and still can transact with the account A or send the related information of the bank card to the account A, at the moment, the invention can improve the vigilance of the users by preventing the transaction and the related information from being successfully sent, and further reduces the cheating probability of social users.
And when detecting that the account number to be confirmed and the social account number perform transfer transaction for the second time or send bank card information, sending an early warning task to a fraud countercheck worker, and confirming whether the fraud countercheck worker is a fraud event to a suspected victim. Under the conditions of fraud warning and first transaction prevention, the account B still initiates transaction or sends related information of a bank card, and is possibly a non-fraud event, but because the account A is suspected to be fraud, the invention adopts a fraud counter to manually confirm the condition, so that normal transaction and the occurrence probability of fraud events are ensured, and the fraud probability of social users is further reduced.
Specifically, the process for the fraud counter-operator to manually confirm the situation is as follows: if so, preventing the transaction from occurring or preventing the bank card information from being sent to the fraud account number to be confirmed, marking the fraud account number to be confirmed as a confirmed fraud account number and carrying out sealing; and if not, marking the fraud account number to be confirmed as a suspected normal account number, and allowing the transaction to continue or allowing a bank card signal to be sent to the suspected normal account number.
Further, before said confirming by the fraud counterfeiter whether the fraud event is a fraud event to the suspected victim: the computer end searches identity information of a suspected victim according to the data matching of the suspected victim social account, the risk level of the fraud account to be confirmed, the suspected victim social account and the fraud type, and respectively generates a high-risk fraud interception task, a medium-risk fraud interception task and a low-risk fraud interception task according to the identity information of the suspected victim and the risk level of the fraud account to be confirmed; the identity information includes: family name, gender, contact details, age, occupation, and whether or not they are fraudulently experienced. People of different ages and professions are different in fraud possibility, and in fraud modes, fraud countermeasures are different, fraud risk confirmation is carried out according to the ages and professions, high-risk fraud intercepting tasks can be processed firstly under the condition that anti-fraud artificial resources are in shortage, and fraud intercepting effects can be guaranteed.
In practice, the confirmation of whether the fraud event is a fraud event to the suspected victim by the fraud countermeasures is: the method comprises the steps that a mobile phone end receives and displays an interception task list, receives an instruction of a fraud counter worker for receiving a current highest-risk interception task, and locks a selected interception task; when the fraud interception task is not picked up after the preset time, sending an early warning short message to warn suspected victims, sending task incompletion information to a computer terminal, and temporarily forbidding the fraud account to be confirmed by the computer terminal.
For the interception task, the priority of the high-risk interception task is higher than that of the medium-risk interception task undoubtedly, and the priority of the medium-risk interception task is higher than that of the low-risk interception task; in the invention, when the early warning counterman receives the interception task, if the high risk interception task exists, the early warning counterman cannot receive the middle risk interception task and the low risk interception task, if the high risk interception task does not exist but the middle risk interception task exists, the early warning counterman can receive the middle risk interception task but cannot receive the low risk interception task, and under the condition of anti-fraud artificial resource shortage, the fraud interception task with higher risk is processed at first, so that the fraud interception effect can be ensured; meanwhile, for the task which is not picked up by people within a certain time, the invention prompts the user by sending the warning short message, and temporarily forbids the fraud account number to be confirmed through the computer terminal, thereby preventing the fraud event.
Preferably, S100 further comprises: and receiving the type of the social account related to fraud, the type related to fraud, the number and the reason for countermeasures input by anti-fraud personnel in batches, and matching and calling an API (application programming interface) provided by the social software service provider according to the type of the social account related to fraud. The method for reverse control of the social account number by means of forbidding or adding fraud warning plug-ins and the like cannot be applied unscrupulously, and normal social contact of social users is easily influenced by false control, so that the method adopts a batch uploading mode after manual auditing, on one hand, the reverse control efficiency is improved, on the other hand, the reverse control accuracy is improved, and the false control probability is reduced. Similarly, the invention can also be applied to the control of the fraud-related websites, and the control of the fraud-related websites and the control of the fraud-related social accounts can be centralized on the same page input and batch control, and the text invention is not repeated.
In specific implementation, the fraud-related social account types and the fraud-related types are indispensable options for selecting input modes, so that the information input efficiency can be improved, the numbers are indispensable items for filling the input modes, the countermeasures reason is unnecessary items, and the countermeasures can be subsequently supplemented, so that the countermeasures efficiency of fraud channels is improved, and the countermeasures can not be abused.
According to another aspect of the present invention, the S100 further includes: acquiring a fraud-related website and judging a fraud-related level of the acquired fraud-related website, wherein the fraud-related level comprises: the confirmed fraud websites and the fraud websites to be confirmed; this step is followed by: and logging out the domain name resolution of the confirmed fraud websites through an API (application programming interface) provided by a server operator, and adding a fraud interception plug-in aiming at the fraud websites to be confirmed, wherein the fraud interception plug-in is used for locking a page when detecting that a user inputs bank card information until a fraud counter man manually issues a lock releasing instruction.
In various fraud types, such as single-swiping fraud, loan fraud, impersonation common law fraud, sent fake wanted and other fraud types, a suspect sends a relevant website to a victim, and the victim basically performs website access by clicking. If the relevant case-related websites are countermarked, when the victim clicks and visits the relevant websites, the victim is prompted to be unable to visit or the websites are suspected to be reported for many times and are sealed, or the page is temporarily locked when the user inputs sensitive information such as a bank card and the like, so that the victim is prevented from browsing the relevant webpages, the victim can be warned, the possibility of being cheated is reduced, or whether the fraud is a fraud event is confirmed manually, on one hand, the countermarking efficiency is improved, on the other hand, the countermarking accuracy is improved, and the false sealing probability is reduced.
According to still another aspect of the present invention, the S100 further includes: acquiring a fraud-related mobile phone number and judging a fraud-related level of the acquired fraud-related mobile phone number, wherein the fraud-related level comprises: the confirmed fraud number and the fraud number to be confirmed; this step is followed by: and locking the confirmed fraud numbers through an API (application program interface) provided by a communication operator, marking the fraud numbers to be confirmed as early warning numbers and sending the early warning numbers to a mobile phone end, and warning suspected victims through the mobile phone end. Telecommunication fraud is cheated by calling and sending short messages at the earliest time, and then is developed into network number change, and with the popularization of the mobile internet, the proportion of crime made by using a network social tool rapidly rises; but the fraud modes of calling and sending short messages still occupy a larger proportion, the invention directly locks the confirmed fraud numbers through the API interface provided by the communication operator, and can prevent fraud molecules from continuously using the fraud numbers to cheat; and the marked fraud numbers to be confirmed are displayed through the mobile phone terminal, so that the suspects with fraud suspects can be prevented from carrying out fraud by using the fraud numbers to be confirmed to a certain extent, and the occurrence probability and loss of fraud events are reduced.
According to yet another aspect of the present invention, the S100 further includes: obtaining false APP information, wherein the false APP information comprises: name, profile, download link, and fraud type; this step is followed by: and sending the false APP information to a mobile phone end, monitoring the mobile phone of the user through the mobile phone end, and warning the user when the mobile phone of the user downloads the suspected false APP application program.
Telecommunication network fraud cases implemented by fraud groups by using false APPs account for about 15% of all fraud cases, the false APPs become indispensable key links in the whole crime chain, and thus a huge technical development gray industry chain is generated, and a large number of illegal criminals participate in the technical development gray industry chain. Related technology developers are definite in work division and plan in groups, various fraud functions of the APP are customized around the specific requirements of telecommunication network fraud groups, some of the APP functions are responsible for writing program codes, some of the APP functions are responsible for purchasing domain names and leasing servers, and some of the APP functions are responsible for packaging and distributing. Through the operation of each link layer by layer, the false APP is sold to fraud groups. Subsequently, the fraud party packages the illegal objects and APP functional characteristics into a very confusing 'regular' application platform, and lures the victim to click a link or scan a two-dimensional code to download the APP, thereby implementing fraud. According to the method and the device, the mobile phone of the user is monitored through the mobile phone terminal, data comparison is carried out when the user downloads the APP, and when the suspected false APP application program is detected, the early warning information is sent to the user, so that the false APP fraud event is reduced, and the application range of fraud countercheck interception is enlarged.
