Description

Technical Field

[0001] The present disclosure belongs to the field of web forensics, and relates to a method for establishing web page levels, in particular to a method, device, medium and electronic device for establishing web page levels. Background Art

[0002] In the field of web forensics, when forensically investigating a third-party website, it is often not just a single page that is extracted. Instead, starting from the website's home page as an entry point, the entire website needs to be fixed. The website can be regarded as a tree structure, with the home page entry as the first level of the website. Clicking on the links in the home page leads to the pages of the second level, and clicking on the links in the pages of the second level leads to the pages of the third level, and so on. By traversing layer by layer, the entire website is fixed.

[0003] It can be seen that the most crucial part here is to obtain the links in the third-party web pages and construct the hierarchical relationship. The traditional way to obtain web page links is to analyze the web page structure and extract the links in the a tags. With the development of technology, such static websites are becoming fewer and fewer, and are replaced by dynamic web pages that use js for direct jump navigation. For such websites, it is impossible to obtain the links by directly analyzing the page structure, and it is also impossible to know which elements can be clicked and jumped by analyzing the website structure. This poses a great challenge to web forensics, and currently, web forensics software on the market cannot well establish the hierarchical relationship of dynamic websites. Summary of the Invention

[0004] The purpose of the present disclosure is to provide a method, device, medium and electronic device for establishing web page levels, which is used to solve the problem that it is difficult to establish the hierarchical relationship of dynamic websites in the actual current forensics process.

[0010] In one embodiment of the present disclosure, the implementation method of jumping to the next-level page based on the jump element of the current web page and dynamically capturing the link of the next-level page by triggering a hook to obtain the link of the next-level page includes: obtaining the jump element selected by the user; jumping to the next-level page based on the selected jump element; and dynamically capturing the link of the next-level page by triggering a hook to obtain the link of the next-level page.

[0011] In one embodiment of the present disclosure, it further includes: dynamically generating an execution script based on the hierarchical relationship; and fixing the website associated with the hierarchical relationship layer by layer based on the execution script.

[0012] In one embodiment of the present disclosure, the read-only protection includes: when the global variable attribute of the V8 engine contains read-only or non-enumerable, throwing a prohibition of redefinition exception.

[0013] In a second aspect, embodiments of the present disclosure provide a web page hierarchy establishment device, including: an engine modification module for modifying the web page V8 engine to bypass the read-only protection of the V8 engine for the global variables to be rewritten; a web page loading module for loading the current web page and injecting a script after successful loading; a link capture module for jumping to the next-level page based on the jump elements of the current web page and dynamically capturing the links of the next-level page by triggering a hook to obtain the links of the next-level page; a hierarchy establishment module for, if the next-level page is the finally jumped page, establishing a hierarchical relationship of the web page links based on the link of the current web page and the link of the next-level page, otherwise returning to the web page loading module, and the page of the current web page in the web page loading module is the next-level page.

[0014] In a third aspect, embodiments of the present disclosure provide a computer-readable storage medium having a computer program stored thereon, and when the computer program is executed by a processor, the hierarchical establishment method described in the second aspect is implemented.

[0018] In addition, the hierarchical establishment method also has the following features: Customizability: The jump elements are specified by the user. Different users can select different jump elements for the same page, and the final hierarchical relationship of the website is also different, meeting the different fixed requirements of different users for the website. Security: This method dynamically intercepts without changing the running logic of the website itself, and the jump elements are specified by the user, thus avoiding clicking on buttons such as the delete button on the web page that change the status of the web page. Efficiency: The jump elements are specified and filtered by the user, and accurate jump interception is performed, avoiding the inefficiency problem existing in analyzing the entire website and performing sequential click tests and waiting.

[0032] The following embodiments of the present disclosure provide a web page hierarchy establishment method, which can be applied to an electronic device as shown in Figure 1 The electronic device described in the present disclosure may include a mobile phone 11 with wireless charging function, a tablet computer 12, a notebook computer 13, a wearable device, a vehicle-mounted device, an augmented reality (AR) / virtual reality (VR) device, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), etc. The specific type of the electronic device is not limited in the embodiments of the present invention.

[0035] Figure 2 is a flowchart showing a method for establishing a web page hierarchy according to an embodiment of the present disclosure. As Figure 2 shown, this embodiment provides a method for establishing a web page hierarchy, including:

[0036] Step S1, modify the web page V8 engine to bypass the read-only protection of the V8 engine for the global variables to be rewritten.

[0037] Optionally, V8 is the name of a JavaScript engine that provides support for the Chrome browser and can be used to execute browser-side JavaScript code. The V8 runtime code can be located in the chromium / src / v8 / src / runtime directory. After modifying the V8 engine runtime code, recompile the browser source code to obtain a new version of the browser, and re-execute the rewriting of the methods in the variable object to be rewritten in the new version of the browser to successfully complete the rewriting.

[0038] Optionally, the method for modifying the web page V8 engine to bypass the read-only protection implementation of the global variables to be rewritten by the V8 engine includes: skipping the read-only check of the global variables to be rewritten in the V8 engine, where the variables to be rewritten include location, history, and windows. Here, location, history, and windows are global variables in the HTML (HyperText Markup Language) web page standard, which will not be elaborated in this embodiment.

[0039] Optionally, the read-only protection includes: when the global variable attribute of the V8 engine contains read-only or non-enumerable, a prohibition of redefinition exception is thrown.

[0040] Optionally, when the global variable attribute of the V8 engine contains read-only or non-enumerable, the specific situation of throwing a prohibition of redefinition exception can be: before modifying the V8 engine, when JavaScript attempts to modify an object, it first uses the LookupIterator method to search for the variable in the global variables. If found, it calls JSReceiver::GetPropertyAttributes to obtain the property of the object, and determines whether its property contains read-only (READ_ONLY) or non-enumerable (DONT_ENUM). If the property contains read-only or non-enumerable, a prohibition of redefinition exception is thrown. The specific form of this exception can be as Figure 3 shown.

[0041] Step S2, load the current web page and inject a script after successful loading.

[0042] Optionally, the script may refer to a script for dynamically capturing web page links through a hook, and the script is injected into each successfully loaded web page.

[0043] Step S3, based on the jump element of the current web page, jump to the next-level page, and dynamically capture the link of the next-level page by triggering the hook to obtain the link of the next-level page.

[0044] Optionally, the jump element may refer to the element on the current web page that can jump to the next-level page.

[0045] Optionally, a hook may refer to various techniques for modifying or extending the behavior of an operating system, application program, or other software components by intercepting function calls, message passing, and event passing between software modules. The code for processing intercepted function calls, events, and messages is called a hook.

[0046] Optionally, the next-level page may refer to the next-level page of the current web page. For example, if the current web page is at the second level, the first-level page is the third-level page.

[0047] Optionally, the implementation method of dynamically capturing the link of the next-level page by triggering a hook to obtain the link of the next-level page includes: dynamically capturing the link of the next-level page based on the rewritten location.href property, rewritten location.hash property, rewritten location.replace method, rewritten location.assign method, rewritten history.pushState method, rewritten history.replaceState method, and rewritten windows.open method to obtain the link of the next-level page.

[0048] Optionally, location may refer to the location property provided by the window object, which is used to obtain or set the URL (Uniform Resource Locator) of the form and can be used to parse the URL. The property returns an object, and this property can be called the location object. Using the properties and methods of location can implement the acquisition and operation of the URL in the browser address bar. window may refer to the window object, and the window object represents the window opened by the browser. history may refer to the history object, and the history object stores all the page URLs visited by the current window.

[0049] The location.href property can set or obtain the URL of the current page. By setting its value to a new URL, page redirection can be achieved. The location.hash property can return the hash in the URL. The location.replace method can replace the history of the current page, preventing the user from returning to the previous page. The location.assign method can load a new URL to achieve the function of page redirection. The history.pushState method means adding a new history record to the current browsing history stack, and the page will not be reloaded after adding. The history.replaceState method is basically the same as the history.pushState method, with only one difference. The history.replaceState method does not generate a new history record but replaces the current history record, and is often used for landing pages. The windows.open method means loading a resource into a new browsing context (such as a window) or an existing browsing context according to the specified parameters.

[0050] Optionally, the implementation method for dynamically capturing the link of the next-level page based on the rewritten history.pushState method includes: Executing the hook: storing the original pushState method of the history object; storing the obtained web page link (the link of the next-level page) in the page cache for subsequent acquisition; calling the stored original pushState method to update the web page normally; after a delay, reverting the web page to the original state. Canceling the hook: restoring it using the stored pushState method.

[0051] Optionally, the implementation method for dynamically capturing the link of the next-level page based on the rewritten history.replaceState method includes: Executing the hook: storing the original replaceState method of the history object; storing the obtained web page link (the link of the next-level page) in the page cache for subsequent acquisition; calling the stored original replaceState method to update the web page normally; after a delay, reverting the web page to the original state. Canceling the hook: restoring it using the stored replaceState method.

[0052] Optionally, an implementation method for dynamically capturing the link of the next-level page based on the rewritten location.href property, rewritten location.hash property, rewritten location.replace method, and rewritten location.assign method includes: Executing the hook: Customize the setHookUrl (set hook URL) method, and this customized setHookUrl method stores the obtained web page link (the link of the next-level page) in the page cache for subsequent acquisition; Store the original location object; Determine the methods and properties that need to be rewritten, namely the replace and assign methods, and the href and hash properties; Traverse all method and property names in the original location. If it is a method that does not need to be rewritten, directly copy the original method. If it is a property that does not need to be rewritten, copy the original property value; Assign values to the replace method and assign method using the customized setHookUrl method; Modify (set) the href property using the customized setHookUrl method, and read (get) the href property using the original href property; Modify (set) the hash property using the customized setHookUrl method, and read (get) the hash property using the original hash property; Canceling the hook: Restore using the stored location object.

[0053] Optionally, an implementation method for dynamically capturing the link of the next-level page based on the rewritten location.href property, rewritten location.hash property, rewritten location.replace method, and rewritten location.assign method can be represented by the following code:

[0054]

[0055]

[0056]

[0057] Optionally, an implementation method for dynamically capturing the link of the next-level page based on the rewritten history.replaceState and pushState methods can be represented by the following code:

[0058]

[0059]

[0060]

[0061] Step S4. If the next-level page is the finally jumped page, establish a hierarchical relationship of web page links based on the link of the current web page and the link of the next-level page; otherwise, return to Step S2, and the page of the current web page in Step S2 is the next-level page.

[0062] Optionally, the hierarchical relationship of the web page links may refer to the hierarchical relationship between the page of the current web page and the next-level page, that is, the hierarchical relationship between the web page pages loaded during the process from Step S1 to Step S4. A website can be regarded as a tree structure. The home page entry is the first level of the website. Jumping to the link in the home page enters the page of the second level. Jumping to the link in the page of the second level enters the page of the third level, and so on. Jumping to the link in the page of the (N - 1)th level enters the page of the Nth level, where N is a positive integer.

[0063] Optionally, the finally jumped page can be flexibly set according to the actual situation, and this embodiment does not clearly limit this.

[0064] According to the above description, the hierarchical relationship establishing method includes: Step S1, modify the web page V8 engine to bypass the read-only protection of the V8 engine for the global variables to be rewritten; Step S2, load the current web page and inject a script after successful loading; Step S3, jump to the next-level page based on the jump element of the current web page, and dynamically capture the link of the next-level page by triggering a hook to obtain the link of the next-level page; Step S4, if the next-level page is the finally jumped page, establish a hierarchical relationship of web page links based on the link of the current web page and the link of the next-level page; otherwise, return to Step S2, and the page of the current web page in Step S2 is the next-level page.

[0065] The hierarchical relationship establishing method can intercept the jump method in the current web page standard and establish a hierarchical relationship of web page links according to the link of the current web page and the link of the next-level page by modifying the V8 engine and dynamically capturing the link of the next-level page by triggering a hook.

[0066] Figure 4 is a flowchart showing an implementation method for dynamically capturing the link of the next-level page based on the rewritten windows.open method according to an embodiment of the present disclosure to obtain the link of the next-level page. As Figure 4 shown, this embodiment provides an implementation method for dynamically capturing the link of the next-level page based on the rewritten windows.open method to obtain the link of the next-level page, including:

[0067] S21. Store the original `windows.open` method.

[0068] Optionally, the original `windows.open` method may refer to the original `windows.open` method of the browser.

[0069] Optionally, the method of storing the original `windows.open` method includes: performing a hook: storing the original `open` method of the `windows` object.

[0070] S22. Store the link of the next-level page in the page cache based on the rewritten `windows.open` method to obtain the link of the next-level page.

[0071] Optionally, the rewritten `windows.open` method may include storing the obtained link in the page cache for subsequent acquisition. The method of storing the link of the next-level page in the page cache based on the rewritten `windows.open` method to obtain the link of the next-level page includes: storing the obtained link (the link of the next-level page) in the page cache to obtain the link of the next-level page.

[0072] Optionally, the page cache is used for subsequent acquisition of the link of the next-level page.

[0073] S23. Restore using the stored `windows.open` method.

[0074] Optionally, restoring using the stored `windows.open` method may refer to restoring the rewritten `windows.open` method to the original `windows.open` method using the stored `windows.open` method.

[0075] Optionally, the method of restoring using the stored `windows.open` method includes: canceling the hook: restoring using the stored `windows.open` method.

[0076] Optionally, the implementation method of dynamically capturing the link of the next-level page based on the rewritten `windows.open` method to obtain the link of the next-level page can be represented by the following code:

[0077]

[0078]

[0079] Figure 5It is a flowchart showing an implementation method of jumping to the next-level page based on a jump element of the current web page according to an embodiment of the present disclosure, and dynamically capturing the link of the next-level page by triggering a hook to obtain the link of the next-level page, as Figure 5 As shown, this embodiment provides an implementation method of jumping to the next-level page based on a jump element of the current web page, and dynamically capturing the link of the next-level page by triggering a hook to obtain the link of the next-level page, including:

[0080] S31, obtain the jump element selected by the user.

[0081] Optionally, the selected jump element may be an element that the user records or batch-selects on the web page that needs to be jumped, and the user may also select to extract table data, pictures, etc. on the web page for custom operations.

[0082] Optionally, the script in step S2 may include the rewritten location.href property, the rewritten location.hash property, the rewritten location.replace method, the location.assign method, the rewritten history.pushState method, the rewritten history.replaceState method, and the rewritten windows.open method, event listening (for recording the user's operations), and the user's interaction interface.

[0083] S32, based on the selected jump element, jump to the next-level page.

[0084] Optionally, the implementation method of jumping to the next-level page based on the selected jump element may be to click on the selected jump element to jump to the next-level page.

[0085] Preferably, the implementation method of jumping to the next-level page based on the selected jump element may include: clicking on the first selected jump element or a relatively typical selected element. The meaning of only selecting one of them is that these batch elements are similar, and as long as one of them is set, it can correspond to the batch elements. The significance of jumping to the next-level page is to open the next-level page to allow the user to continue with the visual setting.

[0086] S33, dynamically capture the link of the next-level page by triggering a hook to obtain the link of the next-level page.

[0087] Figure 6 It is a flowchart showing a method for establishing a web page hierarchy according to an embodiment of the present disclosure, as Figure 6 As shown, this embodiment of the present disclosure provides a method for establishing a web page hierarchy, including:

[0088] S41. Dynamically generate an execution script based on the hierarchical relationship.

[0089] Optionally, the hierarchical relationship may refer to the hierarchical relationship of web page links established by recording user settings. The execution script may refer to a script dynamically generated during the process of constructing the hierarchical relationship according to user settings, and the execution script can fix the websites associated with the hierarchical relationship.

[0090] S42. Fix the websites associated with the hierarchical relationship layer by layer based on the execution script.

[0091] Optionally, the implementation method of fixing the websites associated with the hierarchical relationship layer by layer based on the execution script includes: by executing the generated execution script, batch-fixing the websites according to the user's settings layer by layer, so as to ultimately achieve the purpose of fixing the entire site layer by layer. The websites associated with the hierarchical relationship refer to the entire website including the current web page and the next-level page.

[0092] Figure 7 is a flowchart showing the method for establishing web page levels in an embodiment of the present disclosure. As Figure 7 shown, an embodiment of the present disclosure provides a method for establishing web page levels. As Figure 7 shown, the method for establishing web page levels includes:

[0093] 1. Modify the V8 engine to bypass the read-only protection of global variables such as location by the V8 engine.

[0094] 2. Load the web page and inject the script after the web page is successfully loaded.

[0095] 3. Hook all methods for dynamic web page jumps and dynamically capture jump links when the web page code is executed. This includes rewriting the location.href property, location.hash property, location.replace method, location.assign method, history.pushState method, history.replaceState method, and windows.open method.

[0096] 4. Guide the user to record or batch-select the elements on the web page that need to be jumped. During this period, the user can also choose to extract custom operations such as table data and pictures on the page.

[0097] 5. After the user finishes setting on the current page, click to enter the next-level page. By default, the first element is selected for jumping, or a relatively typical element selected by the user is used for jumping. The meaning of only selecting one of them here is that all elements in this batch are similar, and setting only one of them can correspond to the batch of elements. The significance of jumping to the next-level page is to open the next-level page to allow the user to continue visual setting.

[0098] 6. After the method for triggering the hook dynamically intercepts the link, repeat step 2 until the user exits and continues to jump.

[0099] 7. Record the user's operations, establish the hierarchical relationship of the link according to the user's guidance, and dynamically generate an execution script.

[0100] 8. Execute the generated script to fix the target website in batches according to the user's settings layer by layer, so as to finally achieve the purpose of fixing the entire site layer by layer. The difference between this disclosure and general interception methods lies in: General interception methods have limitations and can only hook some methods and variables not protected by V8, while this disclosure has no such limitation and can intercept all jump methods in the current web page standard. More importantly, the construction of the web page hierarchical relationship is constructed under the user's custom operations, with a more definite target and meeting the requirements for accuracy in the field of evidence collection.

[0101] In an embodiment of the present disclosure, the hierarchical establishment method can fix the evidence collection of a certain illegal website. The hierarchical establishment method includes:

[0102] 1. Prepare a customized version browser with the V8 engine modified.

[0103] 2. Load the illegal website link.

[0104] 3. Automatically inject a script after the website is successfully loaded to hook the method of dynamic jumping.

[0105] 4. Guide the user to batch-select jump elements and enter the next-level page to continue setting.

[0106] 5. Trigger the method of the hook to intercept the jump link.

[0107] 6. Repeat the above step 2 until the user exits the setting.

[0108] 7. Build a hierarchical key according to the user's settings and dynamically generate a script.

[0109] 8. Execute the generated script to fix the entire site layer by layer.

[0110] The protection scope of the web page hierarchy establishment method described in the embodiments of the present disclosure is not limited to the execution order of the steps listed in this embodiment. Any solution achieved by adding or subtracting steps of the prior art or replacing steps according to the principles of the present disclosure is included in the protection scope of the present disclosure.

[0111] Figure 8 shows a web page hierarchy establishment device in the embodiments of the present disclosure. As Figure 8 shown, this embodiment provides a web page hierarchy establishment device 80, including:

[0112] An engine modification module 810, configured to modify the web page V8 engine to bypass the read-only protection of the V8 engine for the global variables to be rewritten.
