Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar modules or modules having the same or similar functionality throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application. On the contrary, the embodiments of the application include all changes, modifications and equivalents coming within the spirit and terms of the claims appended hereto.

For a better understanding of the present application, some terms referred to in the present application will be described first.

Defining:

dynamic debugging: the dynamic behavior of the program is analyzed by using a debugging function provided by a program language or a special debugging tool. The general program language and the debugging tool provide debugging functions of checking a main memory and a register; a breakpoint is set, i.e., when execution is to a specific statement or the value of a specific variable is changed, the program stops execution so as to analyze the state of the program at that time. The operation mechanism of the program can be known through the method.

Static analysis, also known as static code analysis, is a method of debugging a computer program by examining source code or code obtained by reverse analysis, without executing the program. The method can analyze and understand the code structure, and can understand the logic of the program function realization through the analysis of the code.

Communication group: is a combination of something of the same character. In many existing ways, such as social software, IM software, social networking sites, etc., each group sets a certain theme and related organization rules.

Communication software: the software where the communication group is located is, for example, the social software, the IM software, the social network site, and the like. In the embodiment of the present application, IM software is taken as an example.

Among them, IM software is for example: tencent QQ, Yixin, WeChat, nailing, Baidu HI, Feixin, Yixin, Aliwangwang, Jingdongdong, Feiyi, yy, Skype, Google Talk, icq, FastMsg, parox, etc.

Fig. 1 is a flowchart illustrating a method for acquiring a user according to an embodiment of the present application.

Referring to fig. 1, the method of the present embodiment includes:

s11: and acquiring a first account number of the current login communication group.

For example, after the user runs the IM software, the user may log in the IM software using an available account, and after logging in, join the currently processed communication group, where the account currently logged in the communication group may be referred to as a first account.

In some embodiments, the IM software may be executed in a debug mode by a debugger, so that the relevant flow is executed during the execution of the IM software executed in the debug mode.

In some embodiments, the IM software may be executed in a normal manner, for example, a click command of the user to the IM software is received, and the IM software is executed according to the click command. After the IM software is run in a normal manner, a preset code may be injected into the IM software that has already been run, so as to execute the relevant process through the preset code, wherein the injecting of the preset code into the IM software that is running may specifically be in a HOOK manner. See the following description for details.

In addition, an available account in the IM software can be applied, and the IM software can be logged in through the available account.

After logging in the IM software using the available account, the currently logged-in account may be used to join the predetermined group of information to be acquired, for example, the currently logged-in account is used to send an application join request to the group of information to be acquired, and after the group of information to be acquired agrees automatically or after manual approval, the currently logged-in account is added to the group of information to be acquired.

S12: acquiring pre-loading information of the first account, wherein the pre-loading information comprises: information of group members in the communication group.

In order to improve user experience, when the IM software is running, some information related to the currently logged-in account may be preloaded from the local disk and/or from the server via the network, for example, account information of the currently logged-in account (for example, personal information such as gender and age, and the account is status information such as online, offline and stealth), social relationship information such as friends of the currently logged-in account, joined groups and group members, and the like. In addition, the preloaded information also includes information of other users who have social relations with the currently logged-in account, for example, information of friends of the currently logged-in account or group members in the added group.

The above information is not limited to contact information such as account number (e.g. QQ number), phone number, etc., and may also include: IP address, port number, etc.

In addition, typically, the preloaded information is stored encrypted on the local disk and transmitted encrypted when transmitted over the network. However, during the IM operation, the preloaded information is decrypted into plaintext and stored in the memory. And all or part of information can be displayed according to the requirements of the use scene in the IM operation process. For example, friends or group members typically exhibit an account number, nickname, avatar, or the like.

S13: and acquiring the information of the group members in the group according to the preloading information.

Since the preloaded information of the first account includes information of group members of the communication group, the information of the group members in the communication group can be acquired from the preloaded information.

In addition, when acquiring information of group members in the communication group, information of all group members may be acquired, or information of some group members required in the group may be acquired as needed.

Wherein, the information of each group member may include: account number, nickname, contact means, IP address, port number, etc.

As shown above, the above-mentioned flow can be executed by running IM software in a debugging manner, or by injecting preset code into the running IM software. Corresponding embodiments may be as follows.

In some embodiments, referring to fig. 2, the method of obtaining information may include:

s21: the IM software is run in a debug mode through a debugger.

Compared with the operation mode of common IM software, the IM software is operated in a debugging mode, and one or more items of reading, processing and outputting of the specified information can be carried out in the operation process of the IM software.

Specifically, in this embodiment, the IM software running in the debug mode may execute the following process:

s22: logging in IM software using the first account number.

After the IM software is started, the IM software can be logged in by using a pre-applied available account, and the account for logging in the IM software can be referred to as a first account.

S23: and joining a communication group in the IM software by using the first account.

Wherein the joined communication group is a group for which information acquisition is required.

For example, communication group a may be joined if it is desired to obtain information about group members in communication group a.

In addition, if there are a plurality of groups that need to acquire information, each communication group that needs to acquire information may be sequentially taken as a currently processed communication group, and may be sequentially added to the currently processed communication group.

S24: after a first account is used to join the communication group, acquiring pre-loading information of the first account, wherein the pre-loading information comprises: information of group members in the group.

S25: and acquiring information of group members in the communication group in the preloading information.

In some embodiments, referring to fig. 3, the method of obtaining information may include:

s31: the IM software is run in the normal manner.

For example, after receiving a click command of the IM software, the IM software is executed.

S32: and injecting preset code into the running IM software.

For example, by adopting a HOOK mode, when the running of the IM software is detected, preset codes are injected into the running IM software.

S33: and logging in the IM software by using the first account through a preset code.

S34: and joining a communication group in the IM software by using the first account through a preset code.

S35: after a first account is used to join the group through a preset code, acquiring the preloading information of the first account, wherein the preloading information comprises: information of group members in the communication group.

S36: and acquiring the information of the group members in the communication group from the pre-loading information through a preset code.

In the case of the scheme of operating the IM software in the debug mode, S22-S25 are performed by the IM software operating in the debug mode, and in the scheme of injecting the preset code into the IM software, S33-S36 are performed by the preset code. The specific implementation contents of the IM software executed in a debugging mode or the preset code execution can be referred to the above related description, and will not be described in detail here.

In the related art, the user information is extracted through the recorded chat records, but for the group members who do not speak, the information of the group members cannot be acquired because the chat records do not exist. In the embodiment, the information of the group members is obtained from the social relationship information of the currently logged-in account, and the information of the group members can still be obtained for the group members who do not speak, so that the information obtaining scope can be improved. In the related art, only the information such as the phone number and the account number can be extracted at most by extracting the information from the chat records, but in the embodiment, the information such as the phone number and the account number can be obtained by obtaining the information from the social relationship information, and high-quality information such as an IP address and a port number can be obtained, so that the depth of obtaining the information can be improved. In the related art, the information is extracted by extracting the information from the chat records, and the chat records can be generated only after the group members speak, but in the embodiment, the information can be acquired after the group members join the group, and the group members do not need to wait for speaking, so that the timeliness of acquiring the information can be improved. In summary, in the embodiment, the information of the group members of the communication group is acquired according to the preloaded information of the first account, so that the limitation that the information is only acquired from the published chat records can be avoided, and the breadth, depth and timeliness of acquiring the information can be improved.

Whether the IM software is run through a debugger or code is injected into the IM software, in order to obtain the preloaded information, it is necessary to determine the stored information of the preloaded information to obtain the preloaded information according to the stored information.

Fig. 4 is a flowchart illustrating a method for acquiring information according to another embodiment of the present application.

Referring to fig. 4, the method of the present embodiment includes:

s41: and performing static analysis and/or dynamic debugging on the IM software to determine the stored information of the pre-loaded information.

Static analysis and dynamic debugging are two ways to analyze software.

Static analysis is a theory and technology for analyzing software behaviors without executing software. The internal realization mechanism of the software is analyzed and researched by a reverse method, the scheduling logic of data flow and instruction flow in the software is analyzed, and the internal data structure and the encryption algorithm which can be used are analyzed. Dynamic debugging refers to analyzing the dynamic behavior of software running through a special debugging tool. The debugging function provided by the debugging tool comprises an access check main memory and a register; a breakpoint is set, i.e., when execution is to a particular statement or the value of a particular variable is changed, the software suspends execution in order to analyze the state of the software at that time.

In this embodiment, taking static analysis and dynamic debugging as an example, mutual verification is performed by combining two ways, so that a more accurate analysis result can be obtained.

The IM software is subjected to static analysis and dynamic debugging, so that the relevant information of the IM software can be analyzed, wherein one analysis result is the storage information of the preloaded information.

Further, the storage information may comprise different contents according to different storage carriers.

Specifically, when the storage carrier is a memory, the storage information includes: the storage address and data organization in the memory. Wherein, the storage address in the memory is used for indicating the storage position of the information; the data organization form is used for indicating the organization form among information, and may include: a linked list form or an array form.

When the storage carrier is a local disk, the above-mentioned storage information includes: storage address and data organization in the disk.

When the storage carrier is a data packet transmitted by a network, the storage information includes: and transmitting the identification of the header of the data packet of the preloading information.

S42: and after the IM software is operated and the IM software is logged in by using the first account, joining a communication group in the IM software by using the first account.

S43: after a first account is used to join the communication group, acquiring the preloading information of the first account according to the determined storage information, wherein the preloading information comprises: information of group members in the communication group.

After the storage information is determined, the preloading information can be acquired according to the storage information.

Specifically, when the storage carrier is a memory, the storing information includes: the memory address and the data organization form in the memory can obtain the preloading information of the plaintext from the memory according to the memory address and the data organization form in the memory.

For example, the storage address in the memory is specifically a start address, the data organization form is a linked list form, so that the information of the first position can be determined and acquired according to the start address, the next position can be determined and the information of the next position can be acquired according to the pointer in the linked list, and so on, all the preloading information can be acquired according to the pointer. Or the storage addresses in the memory specifically include a start address and an end address, and the data organization form is an array form, so that address increment can be sequentially performed from the start address to the end address, and the pre-loading information in all storage locations between the start address and the end address is acquired.

When the storage carrier is a local disk, the preloaded information stored in the local disk can be obtained in a manner similar to the processing in the memory. Different from the memory storage information, the preloading information is stored in the memory in a plaintext mode, and the preloading information in the disk is in an encrypted form, so that decryption processing is carried out after the preloading information is acquired from the disk, the decrypted preloading information is acquired, and the user information is acquired from the decrypted preloading information.

When the storage carrier is a data packet transmitted in a network, the corresponding data packet can be found according to the packet header identification, and then the preloading information is obtained from the data packet. In addition, the preloaded information included in the data packet is also typically in an encrypted form, and in this case, the preloaded information also needs to be decrypted.

The key used for decryption may be obtained by performing static analysis and/or dynamic debugging on the IM software, or in other manners.

S44: and acquiring information of group members in the communication group in the preloading information.

It is understood that some specific contents in the present embodiment that are not specifically described may be referred to the related description of the above embodiments, and are not described in detail herein.

In this embodiment, on the basis of the above embodiment, by performing static analysis and/or dynamic debugging on the IM software, the storage information of the preloaded information can be determined, and the preloaded information can be accurately obtained.

On the basis of the above embodiment, one or more groups of information to be acquired may be provided, and these groups may form a group queue.

Fig. 5 is a flowchart illustrating a method for acquiring information according to another embodiment of the present application.

In this embodiment, taking an example of running IM software in a debugging manner, taking an example of reading preloaded information from a memory, and taking an example of processing a group queue.

Referring to fig. 5, the method of the present embodiment includes:

s51: and acquiring a storage address and a data organization mode in the memory of the preloaded information through static analysis and dynamic debugging.

The storage address and the data organization mode in the memory can be obtained through a static analysis and dynamic debugging mutual verification mode.

S52: the IM software is run in a debug mode through a debugger.

S53: logging in IM software using the first account number.

S54: and loading the group queue of the information to be acquired.

S55: and determining a currently processed communication group from the group queue, and joining the currently processed communication group by using the first account.

The group queue may be selected as the currently processed group by selecting one group at a time in a sequential manner or a random manner.

S56: according to a memory address and a data organization mode of a memory, acquiring pre-loading information of a first account, wherein the pre-loading information comprises: information of group members in the currently processed communication group.

Specifically, the preloaded information may be obtained after it is determined that the preloaded information is loaded.

Whether the group number of the current processing exists in the memory space of the corresponding address can be judged according to the memory address of the memory, if yes, the preloading information is indicated to be loaded completely, and otherwise, the preloading information is not loaded completely.

S57: in the preloading information, information of group members in the currently processed communication group is acquired.

In addition, after the above information is acquired, the acquired information may be stored in a database or a file system.

In addition, when storing information of a plurality of groups, information of different groups may be stored in association with corresponding group numbers or the like.

S58: and judging whether the group queue has unselected communication groups, if so, repeatedly executing S55 and the subsequent steps, and otherwise, executing S59.

For example, after processing one communication group each time, that is, after performing the above-mentioned S57 corresponding to the currently processed communication group, the currently processed communication group may be deleted in the group queue, so that when the group queue is empty, it may be determined that there is no unselected communication group in the group queue.

Of course, it is understood that a marking mode may also be adopted, in the group queue, initially, each communication group is marked as unselected, and after one communication group is selected each time, the communication group may be marked as selected, so that whether an unselected communication group exists in the group queue may be determined according to the marking.

S59: and (6) ending.
