Abstract: A method for monitoring memory access behavior of a sample process is provided. A processing unit of a computer device determines a page table of the sample process based on a page directory base address of the sample process, where each entry of the page table includes first information, the first information indicates whether the entry has been assigned a guest physical address, the entry that has been assigned the guest physical address includes second information that is used to indicate an access permission of the assigned guest physical address; determines a target entry from the page table, the target entry has been assigned a guest physical address, and an access permission is execution allowed; determines a target host physical address corresponding to the target guest physical address that is assigned to the target entry; and monitors behavior of accessing memory space indicated by the target host physical address.

Abstract: This application provides a program code execution behavior monitoring method. A computer device executes, in a virtual execution environment, first code corresponding to first program code, where the first code belongs to external code, the external code is code, other than internal code, invoked in the first program code, the external code includes system code provided by an operating system of the computer device, and the internal code is code of a process generated by the first program code. In a process of executing the first code, if second code belongs to the internal code, before execution of the second code is completed, the computer device switches an execution environment of the first program code to a simulated execution environment, where the second code is to-be-executed code. The computer device executes the second code in the simulated execution environment.

Abstract: A threat detection method and apparatus, and a network system are disclosed. The threat detection apparatus obtains page code of a first display page group identified by the URL and an overall size occupied by the first display page group in a display area of the browser when loading a URL in a browser of a Web sandbox; inject preset dynamic code into the page code of the first display page group; parses and executes the page code that includes the preset dynamic code; sends a request message when a value of a display variable is greater than or equal to a preset value, to request to obtain page code of a second display page group; receives a response message that carries the page code of the second display page group; and detects in the Web sandbox, whether the page code of the second display page group carries attack code.

Abstract: Example threat detection methods and apparatus are disclosed. One example method includes obtaining page code of a first display page group identified by a uniform resource locator (URL) and an overall size occupied by the first display page group in a display area of a browser of a Web sandbox when loading the URL in the browser. After preset dynamic code is injected into the page code of the first display page group, the page code is parsed and executed. A request message is sent when a value of a display variable is greater than or equal to a preset value, to request to obtain page code of a second display page group. A response message that carries the page code of the second display page group is received. It is further detected, in the Web sandbox, whether the page code of the second display page group carries attack code.
